Multivitamin and L-glutamine drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Multivitamin (ascorbic acid; biotin; cyanocobalamin; dexpanthenol; ergocalciferol; folic acid; niacinamide; pyridoxine hydrochloride; riboflavin phosphate sodium; thiamine hydrochloride; vitamin a; vitamin e) and L-glutamine (glutamine). Common drug interactions include drug ineffective among females and hypertension among males.

The phase IV clinical study analyzes what interactions people have when they take Multivitamin and L-glutamine. It is created by eHealthMe based on reports of 40 people who take the same drugs from the FDA, and is updated regularly.
