Riboflavin (vitamin B2)

Riboflavin (Vitamin B2)

A yellow vitamin of the B complex which is essential for metabolic energy production. It is present in many foods, especially milk, liver, eggs, and green vegetables, and is also synthesized by the intestinal flora. It works with the other B vitamins. And is essential for body growth and the production of red blood cells.

Other Names:

B Complex Vitamin, Complexe de Vitamines B, Flavin, Flavine, Lactoflavin, Lactoflavine, Riboflavina, Riboflavine, Vitamin B-2, Vitamin G, Vitamina B2, Vitamine B2, Vitamine G. Riboflavin is a B vitamin. It can be found in certain foods such as milk, meat, eggs, nuts, enriched flour, and green vegetables. Riboflavin is frequently used in combination with other B vitamins in vitamin B complex products. Vitamin B complex generally includes vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin/niacinamide), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B12 (cyanocobalamin), and folic acid. However, some products do not contain all of these ingredients and some may include others, such as biotin, para-aminobenzoic acid (PABA), choline bitartrate, and inositol.

Riboflavin is used for preventing low levels of riboflavin (riboflavin deficiency), cervical cancer, and migraineheadaches. It is also used for treating riboflavin deficiency, acne, muscle cramps, burning feet syndrome, carpal tunnel syndrome, and blood disorders such as congenital methemoglobinemia and red blood cell aplasia. Some people use riboflavin for eye conditions including eye fatigue, cataracts, and glaucoma.

Other uses include increasing energy levels; boosting immune system function; maintaining healthy hair, skin, mucous membranes, and nails; slowing aging; boosting athletic performance; promoting healthy reproductive function; canker sores; memory loss, including Alzheimer’s disease; ulcers; burns; alcoholism; liver disease; sickle cellanemia; and treating lactic acidosis brought on by treatment with a class of AIDS medications called NRTI drugs.

Riboflavin is required for the proper development and function of the skin, lining of the digestive tract, blood cells, and many other parts of the body.

Effective for:

Preventing and treating riboflavin deficiency and conditions related to riboflavin deficiency.

Possibly Effective for:

Preventing migraine headaches. Taking high-dose riboflavin (400 mg/day) seems to significantly reduce the number of migraine headache attacks. However, taking riboflavin does not appear to reduce the amount of pain or the amount of time a migraine headache lasts. Preventing cataracts, an eye disorder.

Possibly Ineffective for:

Treating migraine headaches.

Insufficient Evidence for:

Lactic acidosis (a serious blood-acid imbalance) in people with acquired immunodeficiency syndrome (AIDS). There is preliminary clinical evidence that riboflavin may be useful for treating lactic acidosis in patients with acquired immunodeficiency syndrome (AIDS) caused by drugs called nucleoside analog reverse transcriptase inhibitors (NRTI). Preventing cervical cancer. There is evidence that increasing riboflavin intake from dietary and supplement sources, along with thiamine, folic acid, and vitamin B12, might decrease the risk of developing precancerous spots on the cervix. Acne. Muscle cramps. Boosting the immune system. Aging. Maintaining healthy skin and hair. Canker sores. Memory loss including Alzheimer’s disease. Other conditions. More evidence is needed to rate the effectiveness of riboflavin for these uses. Riboflavin is LIKELY SAFE for most people. In some people, riboflavin can cause the urine to turn a yellow-orange color. When taken in high doses, riboflavin might cause diarrhea, an increase in urine, and other side effects.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Riboflavin is LIKELY SAFE for pregnant or breast-feeding women when taken in the amounts recommended. The recommended amounts are 1.4 mg per day for pregnant women and 1.6 mg per day in breast-feeding women. Not enough is known about the safety of taking larger doses during pregnancy or breast-feeding.

Minor Interaction. Be watchful with this combination:

Drying medications (Anticholinergic drugs) interacts with RIBOFLAVIN (VITAMIN B2)
Some drying medications can affect the stomach and intestines. Taking these drying medications with riboflavin (vitamin B2) can increase the amount of riboflavin that is absorbed in the body. But it’s not known if this interaction is important.

Medications for depression (Tricyclic antidepressants) interacts with RIBOFLAVIN (VITAMIN B2)
Some medications for depression can decrease the amount of riboflavin in the body. This interaction is not a big concern because it only occurs with very large amounts of some medications for depression.

Phenobarbital (Luminal) interacts with RIBOFLAVIN (VITAMIN B2)
Riboflavin is broken down by the body. Phenobarbital might increase how quickly riboflavin is broken down in the body. It is not clear if this interaction is significant.

Probenecid (Benemid) interacts with RIBOFLAVIN (VITAMIN B2)
Probenecid (Benemid) can increase how much riboflavin is in the body. This might cause there to be too much riboflavin in the body. But it’s not known if this interaction is a big concern.
