The amount of nutrients in this product is relatively nontoxic and is usually well tolerated. However, undesirable effects may occur, particularly when the nutrients are used at high doses (e.g., concomitant use of other multivitamin-mineral supplements), see also Signs and Symptoms of Overdosage under Overdosage.
Vitamin A: Dermatitis and photosensitivity reactions.
Vitamin B2: Riboflavin supplements impart a yellow-orange discoloration to urine. This color has no pathological implication.
Iron: Gastrointestinal (GI) side effects such as epigastric pain/discomfort, nausea, diarrhea, or constipation are usually seen with doses of 60 mg or more elemental iron per day; constipation may lead to fecal impaction, particularly in the elderly; anorexia, black/dark stools, bloating, GI irritation, heartburn, metallic taste, vomiting may also occur, as well as exacerbation of diarrhea in patients with inflammatory bowel disease.
Long-term administration of large amounts of iron may cause hemosiderosis clinically resembling hemochromatosis, which is a genetic condition characterized by excessive iron absorption, excess tissue iron stores, and potential tissue injury.
Brewer's Yeast: Occasional allergic reactions; stomach discomfort and flatulence; migraine headaches have been reported in sensitive individuals.
