Exhibit 99.3

                              REXALL SUNDOWN, INC.
               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION


         On January 7, 2000, Rexall Sundown, Inc. (the "Company") completed its
previously announced purchase (the "Transaction") of privately-held MET-Rx
Nutrition, Inc. ("MET-Rx"), a leader in the sports nutrition and bar categories.
The unaudited pro forma combined financial statements of the Company are
presented to show how the Company and MET-Rx might have looked if they had been
combined for the periods presented. The pro forma information is based on, and
should be read together with, the historical financial statements for the
Company and MET-Rx. Certain amounts in the unaudited pro forma combined
financial statements have been reclassified to conform to the fiscal year 2000
basis presentation. The pro forma financial information was prepared using
assumptions described below and in the related notes thereto.

         The pro forma income statement was prepared as if the transaction took
place on September 1, 1998 and the pro forma balance sheet was prepared as if
the transaction took place on November 30, 1999. As a result of the transaction,
MET-Rx's December fiscal year end will be adjusted to conform to the Company's
August 31 fiscal year end. For pro forma purposes, the Company's results for the
twelve months ended August 31, 1999 were combined with MET-Rx's results for the
twelve months ended August 31, 1999 and the Company's results for the three
months ended November 30, 1999 were combined with MET-Rx's results for the three
months ended November 30, 1999. The attached financial statements give pro forma
effect to (i) the borrowing of approximately $95.0 million to fund the
transaction and (ii) the preliminary allocation of the purchase price to the net
assets of MET-Rx. The pro forma financial statements have not been adjusted for
certain operating efficiencies that may be realized as a result of the
transaction.

         Subsequent to the transaction, the Company may incur certain charges
and expenses outside of the guidance of Emerging Issues Task Force ("EITF") No.
95-3, "Recognition of Liabilities in Connection with a Purchase Business
Combination," related to restructuring and integrating the operations of the
Company and MET-Rx. The objective of such plan will be to enhance productivity
and efficiency of the combined companies by reducing duplicate functions and
overhead costs. The nature of any such charges and expenses may include
provisions for severance and related costs and other charges identified in
connection with the assessment and plan development. Such costs are expected to
approximate $3.0 million for fiscal year 2000. The unaudited pro forma combined
financial statements do not reflect such provisions nor do they include certain
cost savings or operating synergies that may result from the transaction, as
such amounts are not currently determinable.

         The unaudited pro forma combined financial statements are provided for
illustrative purposes only. They do not purport to represent what Rexall
Sundown's results of operations and financial position would have been had the
transaction actually occurred as of the dates indicated, and they do not purport
to project Rexall Sundown's future results of operations or financial position.

         NOTES TO THE UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS


(A)      Income statement amounts reflect MET-Rx's results for the twelve months
         ended August 31, 1999 and the three months ended November 30, 1999. For
         balance sheet purposes, the Company's balance sheet at November 30,
         1999 was combined with MET-Rx's balance sheet at November 30, 1999.

(B)      The total purchase price of the Transaction was $110,986, which was
         financed by borrowings of $95,000 under the Company's new $175,000
         unsecured senior credit facility and its available cash. The senior
         credit facility, which is guaranteed by the Company's domestic
         subsidiaries and is subject to compliance with certain financial
         covenants and ratios, is comprised of a $145,000 three-year revolving
         credit facility and a $30,000 364 day facility. The credit facility
         currently bears interest at LIBOR plus 1.125%, which will adjust
         quarterly based on calculations of the Company's debt to earnings
         before interest, taxes, depreciation and amortization ("EBITDA") ratio.

(C)      Represents loan fees related to the Company's senior credit facility,
         which will be amortized over the term of the credit facility.

(D)      The preliminary allocation of the purchase price to the fair value of
         the net assets acquired is as follows:

           Purchase price                                            $  110,986

               Subtotal                                                  93,406

           Total fair value adjustments                                  (4,896)
                                                                     ----------

                  In accordance with EITF No. 95-3, the Company recognized
                  liabilities assumed in the Transaction with regard to the plan
                  to exit certain leased facilities of MET-Rx and the related
                  severance and relocation costs of certain employees of MET-Rx.
                  These costs are included in the allocation of the acquisition
                  cost in accordance with Accounting Principles Board ("ABP")
                  Opinion No. 16, "Business Combinations."

(E)      Represents the elimination of MET-Rx's outstanding indebtedness, which
         was refinanced in connection with the Transaction.

(F)      Represents the elimination of MET-Rx's historical capital structure.

(G)      Amount represents the amortization of the excess of cost over fair

                                                                    Exhibit 99.3

         NOTES TO THE UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS


(H)      Amount represents a decrease in interest income due to the reduction in
         the available cash balance, as a result of the Transaction and the loan
         fees related to the Company's senior credit facility, as discussed in
         footnotes (B) and (C), respectively.

(I)      Amount represents the reversal of interest expense incurred by MET-Rx
         for the twelve months ended August 31, 1999 and the three months ended
         November 30, 1999 as the underlying debt related to such interest
         expense was repaid as a result of the Transaction.

(J)      Amount represents interest expense incurred on the $95,000 of debt,
         which the Company obtained to finance the Transaction. Interest expense
         for the twelve months ended August 31, 1999 and the three months ended
         November 30, 1999 was calculated as follows:


                                             Twelve Months Ended                Three Months Ended
                                               August 31, 1999                   November 30, 1999
                                             -------------------                -------------------
                                                                               
                  Outstanding debt                  $95,000                          $95,000
                  Estimated interest rate           x  6.35%                         x  7.27%
                                                    --------                         -------
                  Calculated interest expense       $  6,029                         $ 1,726
                                                    ========                         =======


         As noted in footnote (B) above, the senior credit facility bears
         interest at a quarterly variable rate based on LIBOR. A one-eighth of a
         percent increase in interest rates would increase interest expense by
         approximately $119 and $30 for the twelve months ended August 31, 1999
         and the three months ended November 30, 1999, respectively.

(K)      Amount represents the net tax benefit of the change in interest expense
         and interest income as discussed in footnotes (H), (I) and (J) and the
         amortization of loan fees as discussed in footnote (C).
