      Vitamin B Complex Side Effects

      There are very few B Complex Side Effects, however it's advised to take a B complex with food to avoid the feeling of nausea. B vitamins are water soluble and are excreted through sweat and urine so there is little chance of taking too much. It is common to notice a change in color of urine. A common vitamin b complex side effect is a niacin flush. Vitamin B3, niacin promotes blood flow and circulation which can cause a feeling of heat, mild tingling, itch and some redness on the skin. This usually lasts around 20 minutes and can be reduced or prevented by taking B complex vitamins with food.
