Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. 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, the internet and mail order catalogs to customers located primarily in the United States. In addition, the Company manufactures products for both sales to third parties as well as for the VSI product assortment. VSI operates from its headquarters in North Bergen, New Jersey. The condensed consolidated financial statements as of June 27, 2015 and for the three and six months ended June 27, 2015 and June 28, 2014, are unaudited. The condensed consolidated balance sheet as of December 27, 2014 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 27, 2014, as filed with the Securities and Exchange Commission on February 24, 2015 (the “Fiscal 2014 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 period, ending on the last Saturday in December. The results for the three and six months ended June 27, 2015 and June 28, 2014, are each based on 13-week and 26-week periods, respectively. 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. As a result of this deferral, 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 applies only to inventories for which cost is determined by methods other than last-in first-out and the retail inventory method. 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.

Credit Arrangements	6. Credit Arrangements As of June 27, 2015 and December 27, 2014, the Company had $18.0 million and $8.0 million of borrowings outstanding on its Revolving Credit Facility, respectively. Revolving Credit Facility 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 six months ended June 27, 2015 was $27.0 million. There were no borrowings during the six months ended June 28, 2014. The unused available line of credit under the Revolving Credit Facility at June 27, 2015 was $69.2 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 six months ended June 27, 2015 was 1.44%. The commitment fee on the undrawn portion of the $90.0 million Revolving Credit Facility was 0.25% as of June 27, 2015 and December 27, 2014. Interest expense, net for the three and six months ended June 27, 2015 and June 28, 2014 consists of the following (in thousands): Three Months Ended Six Months Ended June 27, June 28, June 27, June 28, Fees on the revolving credit facility and interest $ 140 $ 66 $ 265 $ 131 Amortization of deferred financing fees 40 35 79 67 Interest income (1 ) (1 ) (1 ) (13 ) Interest expense, net $ 179 $ 100 $ 343 $ 185

The following table summarizes restricted share units for the 2009 Plan as of June 27, 2015 and changes during the six month period then ended: Number of Unvested Weighted Unvested at December 27, 2014 9,633 $ 51.37 Granted 5,715 $ 47.19 Vested (12,133 ) $ 50.65 Canceled/forfeited — — Unvested at June 27, 2015 3,215 $ 46.67 Compensation expense attributable to stock based compensation for the three and six months ended June 27, 2015 was approximately $1.3 million and $3.5 million, respectively, and for the three and six months ended June 28, 2014 was approximately $1.9 million and $3.8 million, respectively. As of June 27, 2015, the remaining unrecognized stock based compensation expense for non-vested stock options, restricted shares and restricted share units to be expensed in future periods is $10.7 million, and the related weighted-average period over which it is expected to be recognized is 1.8 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 and restricted share units as of June 27, 2015 is approximately $0.7 million. The weighted-average grant date fair value of stock options during the three and six months ended June 28, 2014 was $19.78 and $19.45, respectively. These valuations represent the fair value of subsequent annual tranches of performance based stock options granted in 2011. There were no such valuations during the three and six months ended June 27, 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 Six Months Ended June 28, June 28, Expected dividend yield 0.0 % 0.0 % Weighted average expected volatility 35.3 % 35.4 % Weighted average risk-free interest rate 1.4 % 1.4 % Expected holding period 4.00 - 4.43 years 4.00 - 4.43 years Treasury Stock-

Earnings Per Share [Abstract]
Net Income Per Share	9. Net Income Per Share The Company’s basic net income per share excludes the dilutive effect of stock options, unvested restricted shares 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 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 Six Months Ended June 27, June 28, June 27, June 28, Numerator: Net income $ 14,241 $ 16,926 $ 32,941 $ 37,435 Denominator: Basic weighted average common shares outstanding 29,230,046 30,436,210 29,363,823 30,325,447 Effect of dilutive securities: Stock options 101,446 255,090 112,515 289,059 Restricted shares 122,635 147,945 183,610 179,595 Restricted share units 1,328 3,488 1,452 2,398 Diluted weighted average common shares outstanding 29,455,455 30,842,733 29,661,400 30,796,499 Basic net income per common share $ 0.49 $ 0.56 $ 1.12 $ 1.23 Diluted net income per common share $ 0.48 $ 0.55 $ 1.11 $ 1.22 Stock options and restricted shares for the three months ended June 27, 2015 and June 28, 2014 in the amount of 3,657 shares and 18,054 shares, respectively, have been excluded from the above calculation as they were anti-dilutive. Stock options and restricted shares for the six months ended June 27, 2015 and June 28, 2014 in the amount of 6,836 shares and 21,998 shares, respectively, have been excluded from the above calculation as they were anti-dilutive.

Share Repurchase Program The Company’s board of directors has approved share repurchase programs that enable the Company to purchase up to $200 million of its shares of common stock from time to time through May 2018. As of June 27, 2015, 1,898,371 shares have been repurchased for a total of $83.4 million. The repurchase programs do 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 and six months ended June 27, 2015, the Company repurchased 226,332 and 626,332 shares, respectively, of its common stock in the open market, which were retired upon repurchase. The total purchase price during the three and six months ended June 27, 2015 was $9.0 million and $25.5 million, respectively, with an average repurchase price per share of $39.76 and $40.78, respectively.

Segment Reporting [Abstract]
Segment Data	12. 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, Super Supplements and Vitapath retail stores in the United States, Puerto Rico and in Canada. The direct segment generates revenue through the sale of VMS products primarily through the Company’s websites and catalog. The Company’s websites offer customers online access to a full assortment of approximately 23,000 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 2014 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 $94.4 million and $96.2 million as of June 27, 2015 and December 27, 2014, respectively. Capital expenditures for the manufacturing segment for the six months ended June 27, 2015 were approximately $2.3 million. At June 27, 2015 and December 27, 2014, long lived assets of the manufacturing segment were $61.0 million and $59.9 million, respectively. The following table contains key financial information of the Company’s business segments (in thousands): Three Months Ended Six Months Ended June 27, June 28, June 27, June 28, Net sales: Retail $ 278,200 $ 269,586 $ 566,183 $ 542,054 Direct 30,346 32,443 65,190 67,811 Manufacturing 24,664 5,014 46,492 5,014 Segment net sales 333,210 307,043 677,865 614,879 Elimination of intersegment revenues (10,872 ) (825 ) (18,692 ) (825 ) Net sales $ 322,338 $ 306,218 $ 659,173 $ 614,054 Income from operations: Retail $ 51,613 $ 51,737 $ 107,672 $ 108,436 Direct 5,587 5,760 10,652 12,785 Manufacturing (1) (1,510 ) (871 ) (1,211 ) (871 ) Corporate costs (2) (32,126 ) (28,460 ) (62,594 ) (57,937 ) Income from operations $ 23,564 $ 28,166 $ 54,519 $ 62,413 During Fiscal 2014, the Company determined the acquired manufacturing operations represented a reportable segment.
