Vitamin B2 or riboflavin is a supplement to prevent and overcome vitamin B2 deficiency (deficiency). Vitamin B2 works with other B vitamins to maintain healthy skin, nerves, eyes, and red blood cells. Vitamin B2 can be found in milk, bread, meat, eggs, beans, and green vegetables. In addition, vitamin B2 can also be found in supplement form. Vitamin B2 supplements are often found in multivitamins that are available in tablet, syrup, or capsule form.

Vitamin B2 supplements are given to people with vitamin B2 deficiency who can't get enough of this vitamin from food. Vitamin B2 deficiency can occur in people who suffer from certain conditions, such as prolonged infections, liver disease, diseases of the digestive tract, alcoholism, or cancer.

How to Take Vitamin B2 Correctly

Vitamin and mineral supplements are taken to supplement the intake of vitamins and minerals, especially when nutritional intake from food is not sufficient. Keep in mind, supplements are only as a complement, not as a substitute for nutrients from food.

Follow the doctor's recommendations and always read the instructions for use listed on the supplement packaging. Do not increase the dose or take vitamin B2 supplements too often, to avoid side effects. This supplement should be taken with meals. Absorption of vitamin B2 by the body will be better if taken with food. Store vitamin B2 in a place away from direct sunlight. Keep supplements out of reach of kids.
