Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Vitamin Shoppe, Inc. (“ VSI ”), is incorporated in the State of Delaware, and through its wholly-owned subsidiary, Vitamin Shoppe Industries Inc. (“Subsidiary” or “Industries” together with VSI, the “Company”), is a multi-channel specialty retailer and contract manufacturer of nutritional products. Sales of both national brands and our own brands of vitamins, minerals, herbs, specialty supplements, sports nutrition and other health and wellness products (“VMS products”) are made through VSI-operated retail stores and the internet to customers located primarily in the United States. The Company manufactures products for both sales to third parties as well as for the VSI product assortment. The condensed consolidated financial statements as of March 26, 2016 and March 28, 2015 are unaudited. The condensed consolidated balance sheet as of December 26, 2015 was derived from our audited financial statements. All intercompany transactions and balances have been eliminated in consolidation. In addition, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted. The interim financial statements reflect all adjustments, which are, in the opinion of management, necessary for a fair presentation in conformity with GAAP. The interim financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Form 10-K for the fiscal year ended December 26, 2015, as filed with the Securities and Exchange Commission on February 23, 2016 (the “Fiscal 2015 Form 10-K”). The results of operations for the interim periods should not be considered indicative of results to be expected for the full year. The Company's fiscal year ends on the last Saturday in December. As used herein, the term "Fiscal Year" or "Fiscal" refers to a 52-week or 53-week period, ending on the last Saturday in December. Fiscal 2016 is a 53-week fiscal year. The results for the three months ended March 26, 2016 and March 28, 2015 are each based on 13-week periods. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements, and revenue and expenses during the reporting period. Actual results could differ from those estimates. Except as noted below, the Company has considered all new accounting pronouncements and has concluded that there are no new pronouncements that may have a material impact on its results of operations, financial condition, or cash flows, based on current information. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606). Under ASU 2014-09, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB deferred the effective date of ASU 2014-09 by one year. ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017 for public companies and early adoption of ASU 2014-09 is permitted for public companies for annual reporting periods beginning after December 15, 2016. The Company is evaluating ASU 2014-09 to determine if this guidance will have a material impact on the Company’s condensed consolidated financial statements. In July 2015, the FASB issued Accounting Standards Update No. 2015-11 (“ASU 2015-11”), Simplifying the Measurement of Inventory (Topic 330). ASU 2015-11 simplifies the subsequent measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption of ASU 2015-11 is permitted. The Company is evaluating ASU 2015-11 to determine if this guidance will have a material impact on the Company’s condensed consolidated financial statements. In February 2016, the FASB issued Accounting Standards Update No. 2016-02 (“ASU 2016-02”), Leases (Topic 842). ASU 2016-02 was issued by the FASB to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. ASU 2016-02 will require modified retrospective application at the beginning of our first quarter of Fiscal 2019, but permits adoption in an earlier period. The Company is evaluating ASU 2016-02 in order to determine the impact of this guidance on the Company’s condensed consolidated financial statements and anticipates this guidance will significantly impact our condensed consolidated financial statements given we have a significant number of leases. In March 2016, the FASB issued Accounting Standards Update No. 2016-09 (“ASU 2016-09”), Compensation-Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 addresses simplification of several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption of ASU 2016-09 is permitted. The Company is evaluating ASU 2016-09 to determine if this guidance will have a material impact on the Company’s condensed consolidated financial statements.

Debt Disclosure [Abstract]
Credit Arrangements	Credit Arrangements Convertible Senior Notes due 2020 On December 9, 2015, the Company completed an offering of $143.8 million of its 2.25% Convertible Senior Notes due 2020 (the “Convertible Notes”). The Convertible Notes are senior unsecured obligations of the Company. Interest on the Convertible Notes is payable on June 1 and December 1 of each year, commencing on June 1, 2016 until their maturity date of December 1, 2020. The Company may not redeem the Convertible Notes prior to the maturity date. Prior to July 1, 2020, the Convertible Notes will be convertible only under certain circumstances. The Convertible Notes will be convertible at an initial conversion rate of 25.1625 shares of the Company’s common stock per $1,000 principal amount of the Convertible Notes, which is equivalent to an initial conversion price of approximately $39.74 . The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date, the Company is required to increase, in certain circumstances, the conversion rate for a holder who elects to convert its Convertible Notes in connection with such a corporate event including customary conversion rate adjustments in connection with a “make-whole fundamental change” as defined. Upon conversion, the Company may satisfy its conversion obligation by paying or delivering, as applicable, cash, shares of its common stock or a combination of cash and shares of its common stock, at its election. The Company allocated the principal amount of the Convertible Notes between its liability and equity components (see table below). The carrying amount of the liability component was determined by measuring the fair value of a similar debt instrument of similar credit quality and maturity that did not have the conversion feature. The carrying amount of the equity component, representing the embedded conversion option, was determined by deducting the fair value of the liability component from the principal amount of the Convertible Notes as a whole. The equity component was recorded to additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the Convertible Notes over the carrying amount of the liability component was recorded as a debt discount, and is being amortized to interest expense using an effective interest rate of 3.8% over the term of the Convertible Notes. The Company allocated the total amount of transaction costs incurred to the liability and equity components using the same proportions as the proceeds from the Convertible Notes. Transaction costs attributable to the liability component were recorded as a direct deduction from the liability component of the Convertible Notes, and are being amortized to interest expense using the effective interest method through the maturity date. Transaction costs attributable to the equity component were netted with the equity component of the Convertible Notes in additional paid-in capital. The Convertible Notes consist of the following components (in thousands): March 26, 2016 December 26, 2015 Liability component: Principal $ 143,750 $ 143,750 Conversion feature (24,800 ) (24,800 ) Liability portion of debt issuance costs (3,792 ) (3,800 ) Amortization 1,585 260 Net carrying amount $ 116,743 $ 115,410 Equity component: Conversion feature $ 24,800 $ 24,800 Equity portion of debt issuance costs (793 ) (793 ) Deferred taxes 941 941 Net carrying amount $ 24,948 $ 24,948 In connection with the issuance of the Convertible Notes, the Company entered into convertible note hedge transactions for which it paid an aggregate $26.4 million . In addition, the Company sold warrants for which it received aggregate proceeds of $13.0 million . The convertible note hedge transactions are expected generally to reduce potential dilution of the Company’s common stock upon any conversion of notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted notes. However, the warrant transaction could separately have a dilutive effect to the extent that the market value per share of the Company’s common stock exceeds the applicable strike price of the warrant transactions, which is approximately $52.99 at inception. As these transactions meet certain accounting criteria, the convertible note hedge and warrant transactions are recorded in stockholders’ equity, are not accounted for as derivatives and are not remeasured each reporting period. The net proceeds from the Convertible Notes and related transactions of $125.7 million , net of commissions and offering costs of $4.6 million , were used to repurchase shares of the Company’s common stock under the Company’s share repurchase programs. Refer to Note 9. Share Repurchase Programs for additional information. Revolving Credit Facility As of March 26, 2016 and as of December 26, 2015 , the Company had $6.0 million and $8.0 million of borrowings outstanding on its Revolving Credit Facility (the "Revolving Credit Facility"), respectively. Subject to the terms of the Revolving Credit Facility, which has a maturity date of October 11, 2018 , the Company may borrow up to $90.0 million , with a Company option to increase the facility up to a total of $150.0 million . The availability under the Revolving Credit Facility is subject to a borrowing base calculated on the value of certain accounts receivable as well as certain inventory of the Company. The obligations thereunder are secured by a security interest in substantially all of the assets of the Company. Under the Revolving Credit Facility, VSI has guaranteed the Company’s obligations, and Industries and its wholly-owned subsidiaries have each guaranteed the obligations of the other respective entities. The Revolving Credit Facility provides for affirmative and negative covenants affecting the Company. The Revolving Credit Facility restricts, among other things, the Company’s ability to incur indebtedness, create or permit liens on the Company’s assets, declare or pay dividends and make certain other restricted payments, consolidate, merge or recapitalize, sell assets, make certain investments, loans or other advances, enter into transactions with affiliates, change our line of business, and restricts the types of hedging activities the Company can enter into. The largest amount borrowed during the three months ended March 26, 2016 and March 28, 2015 was $15.0 million and $18.0 million , respectively. The unused available line of credit under the Revolving Credit Facility at March 26, 2016 was $81.1 million . Borrowings under the Revolving Credit Facility accrue interest, at the Company’s option, at the rate per annum based on an “alternative base rate” plus 0.25% or 0.50% or the adjusted Eurodollar rate plus 1.25% or 1.50% , in each case with the higher spread applicable in the event that the aggregate amount of the borrowings under the Revolving Credit Facility exceeds 50% of the borrowing base availability under the Revolving Credit Facility. The weighted average interest rate for the Revolving Credit Facility during the three months ended March 26, 2016 and March 28, 2015 was 1.70% and 1.44% , respectively. The commitment fee on the undrawn portion of the $90.0 million Revolving Credit Facility was 0.25% as of March 26, 2016 and December 26, 2015 . Interest expense, net for the three months ended March 26, 2016 and March 28, 2015 consists of the following (in thousands): Three Months Ended March 26, 2016 March 28, 2015 Amortization of debt discount on convertible notes $ 1,134 $ — Interest on convertible notes 804 — Amortization of deferred financing fees 237 39 Interest / fees on the revolving credit facility and other interest 87 125 Interest expense, net $ 2,262 $ 164

The following table summarizes restricted share units for the 2009 Plan as of March 26, 2016 and changes during the three month period then ended: Number of Unvested Weighted Unvested at December 26, 2015 11,280 $ 37.25 Granted — $ — Vested (3,760 ) $ 37.25 Canceled/forfeited — $ — Unvested at March 26, 2016 7,520 $ 37.25 The total intrinsic value of restricted share units vested during the three months ended March 26, 2016 and March 28, 2015 , was $0.1 million and $0.4 million , respectively. Compensation expense attributable to stock based compensation for the three months ended March 26, 2016 and March 28, 2015 , was approximately $1.7 million and $2.1 million , respectively. As of March 26, 2016 , the remaining unrecognized stock based compensation expense for non-vested stock options, restricted shares, performance share units and restricted share units to be expensed in future periods is $13.0 million , and the related weighted-average period over which it is expected to be recognized is 2.1 years. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company estimates forfeitures based on its historical forfeiture rate since the inception of granting stock based awards. The estimated value of future forfeitures for stock options, restricted shares, performance share units and restricted share units as of March 26, 2016 is approximately $1.1 million . The weighted-average grant date fair value of stock options was $8.30 during the three months ended March 26, 2016. Stock options were not granted during the three months ended March 28, 2015. The fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions: Three Months Ended March 26, 2016 Expected dividend yield 0.0 % Weighted average expected volatility 32.6 % Weighted average risk-free interest rate 1.2 % Expected holding period 4.00 years Treasury Stock – As part of the Company’s equity incentive plans, the Company makes required tax payments on behalf of employees as their restricted shares vest. The Company withholds the number of vested shares having a value on the date of vesting equal to the minimum statutory tax obligation. The shares withheld are recorded as treasury shares. During the three months ended March 26, 2016 , the Company purchased 6,965 shares in settlement of employees’ tax obligations for a total of $0.2 million . The Company accounts for treasury stock using the cost method. These shares are available to grant under the Company’s equity incentive plans.

Earnings Per Share [Abstract]
Net Income Per Share	Net Income Per Share The Company’s basic net income per share excludes the dilutive effect of stock options, unvested restricted shares, unvested performance share units and unvested restricted share units. It is based upon the weighted average number of common shares outstanding during the period divided into net income. Diluted net income per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. Stock options, unvested restricted shares, unvested performance share units and unvested restricted share units are included as potential dilutive securities for the periods applicable, using the treasury stock method to the extent dilutive. The components of the calculation of basic net income per common share and diluted net income per common share are as follows (in thousands except share and per share data): Three Months Ended March 26, 2016 March 28, 2015 Numerator: Net income $ 14,782 $ 18,700 Denominator: Basic weighted average common shares outstanding 24,802,335 29,497,599 Effect of dilutive securities: Stock options 73,372 123,583 Restricted shares 132,617 244,585 Performance share units 169 — Restricted share units 565 1,577 Diluted weighted average common shares outstanding 25,009,058 29,867,344 Basic net income per common share $ 0.60 $ 0.63 Diluted net income per common share $ 0.59 $ 0.63 Stock options and restricted shares for the three months ended March 26, 2016 and March 28, 2015 in the amount of 10,159 shares and 10,015 shares, respectively, have been excluded from the above calculation as they were anti-dilutive. The Company has the intent and ability to settle the principal portion of its Convertible Notes in cash, and as such, has applied the treasury stock method, which has resulted in the underlying convertible shares being anti-dilutive for the three months ended March 26, 2016 as the Company’s average stock price was less than the conversion price. Refer to Note 5. Credit Arrangements for additional information on the Convertible Notes.

Share Repurchase Programs	Share Repurchase Programs On August 5, 2014 , May 6, 2015 and November 23, 2015, the Company’s board of directors approved share repurchase programs that enable the Company to purchase up to an aggregate of $300 million of its shares of common stock from time to time over three year periods ending on August 4, 2017 , May 5, 2018 and November 22, 2018 , respectively. As of March 26, 2016 , 7,181,363 shares have been repurchased for a total of $246.2 million . The repurchase program does not obligate the Company to acquire any specific number of shares of its common stock and may be suspended, terminated or modified at any time for any reason, including market conditions, the cost of repurchasing such shares, the availability of alternative investment opportunities, liquidity, and other factors deemed appropriate. These factors may also affect the timing and amount of share repurchases. During the three months ended March 26, 2016 and March 28, 2015 , the Company repurchased 787,875 and 400,000 shares, respectively, of its common stock in the open market. The shares were retired upon repurchase. Open market share repurchases were $23.3 million in the three months ended March 26, 2016 and $16.5 million in the three months ended March 28, 2015 with average repurchase prices per share of $29.56 and $41.35 , respectively. In the first fiscal quarter of 2016, the Company also repurchased 646,666 shares of its common stock for $19.0 million , or $29.40 per share, under a 10b5-1 program which the Company entered into to purchase shares under predetermined criteria. Additionally, the Company has entered into accelerated share repurchase (“ASR”) arrangements with financial institutions. In exchange for an up-front payment, the financial institutions initially delivered shares of the Company’s common stock. The total number of shares ultimately delivered, and therefore the average repurchase price paid per share, is determined at the end of the purchase period of each ASR based on the volume weighted-average price of the Company’s common stock during that period. The shares were retired in the periods they are delivered, and each up-front payment was accounted for as a reduction to stockholders’ equity in the Company’s Condensed Consolidated Balance Sheet in the period the payment was made. The Company reflects each ASR as a repurchase of common stock in the period delivered for purposes of calculating earnings per share and as a forward contract indexed to its own common stock. The ASRs met all of the applicable criteria for equity classification, and therefore, were not accounted for as derivative instruments. The following table summarizes the Company’s ASR arrangements: Beginning of ASR Period Up-front Payment (in millions) Initial Share Deliveries End of ASR Period Final Shares Delivered Average Repurchase Price November, 2014 $ 50.0 982,714 January, 2015 88,325 $ 46.68 December, 2015 $ 50.0 1,391,940 February, 2016 235,053 $ 30.73

Segment Reporting [Abstract]
Segment Data	Segment Data The Company currently operates three business segments, retail, direct and manufacturing. The operating segments are segments of the Company for which separate financial information is available and for which operating results are evaluated regularly by executive management in deciding how to allocate resources and in assessing performance. The Company's management evaluates segment operating results based on several indicators. The primary key performance indicators are sales and operating income for each segment. The table below represents key financial information for each of the Company's business segments as well as corporate costs. The retail segment primarily includes the Company's retail stores. The retail segment generates revenue primarily through the sale of VMS products through Vitamin Shoppe and Super Supplements retail stores in the United States and Puerto Rico. The direct segment generates revenue through the sale of VMS products primarily through the Company's websites. The Company's websites offer customers online access to a full assortment of approximately 18,000 SKUs. The manufacturing segment supplies the retail and direct segments, along with various thirds parties, with finished products for sale. Corporate costs represent all other expenses not allocated to the retail, direct or manufacturing segments which include, but are not limited to: human resources, legal, retail management, direct management, finance, information technology, depreciation (primarily related to assets utilized by the retail and direct business segments as well as corporate assets) and amortization, and various other corporate level activity related expenses. Intercompany sales transactions are eliminated in consolidation. The Company’s segments are designed to allocate resources internally and provide a framework to determine management responsibility. The accounting policies of the segments are consistent with those described in Note 2. Summary of Significant Accounting Policies in the Fiscal 2015 Form 10-K. The Company has allocated $165.3 million , $45.3 million and $32.6 million of its recorded goodwill to the retail, direct and manufacturing segments, respectively. The Company does not have identifiable assets separated by segment, with the exception of the identifiable assets of the manufacturing segment which were $91.6 million and $88.4 million as of March 26, 2016 and December 26, 2015, respectively. Capital expenditures for the manufacturing segment for the three months ended March 26, 2016 and March 28, 2015 were approximately $0.4 million and $1.1 million , respectively. At March 26, 2016 and December 26, 2015 , long lived assets of the manufacturing segment were $60.0 million and $60.4 million , respectively. Depreciation and amortization expense, included in selling, general and administrative expenses, for the manufacturing segment during the three months ended March 26, 2016 and March 28, 2015 was approximately $0.4 million and $0.3 million , respectively.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value hierarchy requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, while Level 3 generally requires significant management judgment. The three levels are defined as follows: • Level 1: Unadjusted quoted prices in active markets for identical assets and liabilities. • Level 2: Observable inputs other than those included in Level 1. For example, quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets. • Level 3: Unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability. The Company’s financial instruments include cash, accounts receivable, accounts payable and its Revolving Credit Facility. The Company believes that the recorded values of these financial instruments approximate their fair values due to their nature and respective durations. The following table contains information of the Company’s Convertible Notes (in thousands): March 26, 2016 December 26, 2015 Fair Value $ 113,011 $ 119,784 Carrying Value 116,743 115,410 The fair value of the Convertible Notes was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, including the trading price of the Company’s Convertible Notes, when available, the Company’s stock price and interest rates based on similar debt issued by parties with credit ratings similar to the Company (Level 1 or 2). Certain assets are measured at fair value on a non-recurring basis, that is, the assets are subject to fair value adjustments in certain circumstances such as when there is evidence of impairment. These measures of fair value, and related inputs, are considered Level 2 or 3 measures under the fair value hierarchy.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements, and revenue and expenses during the reporting period. Actual results could differ from those estimates.
New Accounting Pronouncements	Except as noted below, the Company has considered all new accounting pronouncements and has concluded that there are no new pronouncements that may have a material impact on its results of operations, financial condition, or cash flows, based on current information. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606). Under ASU 2014-09, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB deferred the effective date of ASU 2014-09 by one year. ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017 for public companies and early adoption of ASU 2014-09 is permitted for public companies for annual reporting periods beginning after December 15, 2016. The Company is evaluating ASU 2014-09 to determine if this guidance will have a material impact on the Company’s condensed consolidated financial statements. In July 2015, the FASB issued Accounting Standards Update No. 2015-11 (“ASU 2015-11”), Simplifying the Measurement of Inventory (Topic 330). ASU 2015-11 simplifies the subsequent measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption of ASU 2015-11 is permitted. The Company is evaluating ASU 2015-11 to determine if this guidance will have a material impact on the Company’s condensed consolidated financial statements. In February 2016, the FASB issued Accounting Standards Update No. 2016-02 (“ASU 2016-02”), Leases (Topic 842). ASU 2016-02 was issued by the FASB to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. ASU 2016-02 will require modified retrospective application at the beginning of our first quarter of Fiscal 2019, but permits adoption in an earlier period. The Company is evaluating ASU 2016-02 in order to determine the impact of this guidance on the Company’s condensed consolidated financial statements and anticipates this guidance will significantly impact our condensed consolidated financial statements given we have a significant number of leases. In March 2016, the FASB issued Accounting Standards Update No. 2016-09 (“ASU 2016-09”), Compensation-Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 addresses simplification of several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption of ASU 2016-09 is permitted. The Company is evaluating ASU 2016-09 to determine if this guidance will have a material impact on the Company’s condensed consolidated financial statements.
