I,
      Bruce J. Wood, certify that:





1.      I
      have reviewed this quarterly report
      on Form 10-Q of Schiff Nutrition International, Inc.;





2.      Based
      on my knowledge, this report does
      not contain any untrue statement of a material fact or omit to state a material
      fact necessary to make the statements made, in light of the circumstances under
      which such statements were made, not misleading with respect to the period
      covered by this report;





3.      Based
      on my knowledge, the financial
      statements, and other financial information included in this report, fairly
      present in all material respects the financial condition, results of operations
      and cash flows of the registrant as of, and for, the periods presented in this
      report;





4.      The
      registrant's other certifying
      officer and I are responsible for establishing and maintaining disclosure
      controls and procedures (as defined in Exchange Act Rules 13a-15(e) and
      15d-15(e)) for the registrant and have:




(a)           Designed
      such disclosure controls and
      procedures, or caused such disclosure controls and procedures to be designed
      under our supervision, to ensure that material information relating to the
      registrant, including its consolidated subsidiaries, is made known to us by
      others within those entities, particularly during the period in which this
      report is being prepared;




(b)           Evaluated
      the effectiveness of the
      registrant's disclosure controls and procedures and presented in this report
      our
      conclusions about the effectiveness of the disclosure controls and procedures,
      as of the end of the period covered by this report based on such evaluation;
      and




(c)           Disclosed
      in this report any change in
      the registrant's internal control over financial reporting that occurred during
      the registrant's most recent fiscal quarter that has materially affected, or
      is
      reasonably likely to materially affect, the registrant's internal control over
      financial reporting; and





5.      The
      registrant's other certifying
      officer and I have disclosed, based on our most recent evaluation of internal
      control over financial reporting, to the registrant's auditors and the audit
      committee of the registrant's board of directors (or persons performing the
      equivalent functions):




(a)           All
      significant deficiencies and
      material weaknesses in the design or operation of internal control over
      financial reporting which are reasonably likely to adversely affect the
      registrant's ability to record, process, summarize and report financial
      information; and




(b)           Any
      fraud, whether or not material,
      that involves management or other employees who have a significant role in
      the
      registrant's internal control over financial reporting.
