of dietary supplement dosage recommendations is regulated by the
amount of U.S. RDA (Recommended Daily Allowances) on a Nutrition
Facts panel is required for foods and was previously used to label
dietary supplement regulations went into effect in March of 1999
that require labeling of Dietary Reference Intakes (DRI) and which
appear as "DV" (Daily Values) on a Supplement Facts panel. DVs recommend
higher levels of intake than RDAs.
standards for dosage recommendation have been criticized for addressing
only adequate levels of nutrition rather than optimum nutritional
intakes, thus failing to inform consumers of the potential health
benefits that can be rendered from higher dosage levels. The market
has demonstrated demand for some ingredients far above those recommended
by the government as can be seen on product labels. It is not uncommon
to see RDA or DV values of over 1000 (tens times the amount recommended
under RDA or DV guidelines).
government regulations are slow to change, they can easily fall
out of step with the evolving body of nutritional knowledge which
is growing rapidly. New information about biologically active components
and their recommended use is being discovered all the time.
different individual nutritional needs as well as different health
goals may call for different nutritional programs. Therefore, a
more flexible, self-regulating means of recommending dosages is
needed in order to respond quickly to scientific advances and to
best serve the consuming public. This is served indirectly now by
the free flow of information to consumers via the press, the Internet,
book stores and libraries, and the advice of health care providers.
