Can vitamin supplements cause dependency? Will I go through withdrawals if I stop taking them?
Vitamins are molecular compounds necessary for normal health and growth in higher forms of animal life, including humans. Humans must obtain essential vitamins from food or from supplements because the human body cannot produce these compounds on its own. Lack of a particular vitamin in the diet may lead to a deficiency disease. (This is how vitamins were first discovered.)
Aside from the possibility of inadequate nutrient intake from the diet, no side-effects are associated with discontinuation of the USANA supplements.
