TERM TRADEMARK COLLATERAL ASSIGNMENT

      IVC INDUSTRIES, INC., a Delaware corporation and VITAMIN SPECIALTIES
CORP., a Pennsylvania corporation (collectively, the "Assignors"), do hereby
grant, assign and convey to THE CHASE MANHATTAN BANK, as agent under the Term
Loan Agreement referred to below (the "Agent"), the registered trademarks and
trademark applications identified on Annex I hereto and the goodwill represented
thereby (the "Trademarks") together with all the proceeds thereof, as collateral
security for all the Liabilities (as hereinafter defined);

      SUBJECT TO a reservation on the part of the Assignors (until the
occurrence of an Event of Default, as hereinafter defined) of a license to use
the Trademarks for the Assignors' own benefit, provided that such use does not
violate the terms of the Term Loan Agreement or any of the other Term Loan
Documents. The license so reserved shall terminate upon the occurrence of an
Event of Default.

      This Assignment is being executed and delivered pursuant to the Term Loan
Agreement dated as of the date hereof (which, as the same may hereafter be
amended or supplemented from time to time, will be called, the "Term Loan
Agreement") between IVC Industries, Inc., the Banks party thereto and the Agent.
All capitalized terms used in this Assignment and not defined shall have the
respective meanings ascribed to them in the Term Loan Agreement.

      As used herein, the term "Liabilities" means all indebtedness, obligations
and liabilities of every kind and nature of the Assignor to any or all of the
Banks and the Agent under any or all of the Term Loan Agreement and the other
Term Loan Documents.

      The assignment effected hereby shall be governed by Article 9 of the New
York Uniform Commercial Code. Upon the occurrence and during the continuance of
an Event of Default, the Assignee shall have the rights and remedies of a
secured party as set forth therein (including, without limitation, the right to
dispose of the Trademarks and to apply the proceeds of the disposition to
satisfy the Obligations) and otherwise available at law or in equity.

      The Agent shall have no duties with respect to the Trademarks, other than
the duties of a secured party under the New York Uniform Commercial Code.
Without limiting the generality of the foregoing, the Agent shall have no duty
to prosecute any action for trademark infringement against any person.

      The address of the Agent for purposes of this Assignment is:

            The Chase Manhattan Bank
            One Riverfront Plaza
            Newark, New Jersey 07102

or such other address as the Agent may designate to the Assignor in writing from
time to time.

      This Assignment shall bind and inure to the benefit of the parties hereto
and their respective successors and assigns.
