 I,
        Bruce J. Wood, certify that:
 
 1.      I
        have reviewed this annual report on
        Form 10-K 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 fourth 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.
