This product is contraindicated in an individual with a history of hypersensitivity to any of its ingredients.

Iodine may occasionally cause an allergic reaction in some individuals. As vitamin K interferes with the effect of anticoagulant drugs (like Coumadin), the concurrent use of these agents should be avoided. 5-methyltetrahydrofolate (5-MTHF) supplementation is not recommended concurrent with methotrexate cancer therapy, as it can interfere with methotrexate's anti-neoplastic activity; however, this folate source has not been shown to interfere with the anti-inflammatory activity of methotrexate. An individual taking methotrexate for psoriasis or rheumatoid arthritis can safely take a supplement containing folate. Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under six. Keep this product out of reach of children. In case of accidental overdose, call a doctor or poison control centre immediately. Vitamin C can cause diarrhoea in some individuals in large doses, which can vary from person to person and resolves when the amount is reduced.
