Vitamin B2 is commonly known as Riboflavin and is a member of the B-Vitamin family. Vitamin B2 occurs naturally in green vegetables, liver, kidneys, wheat germ, milk, eggs, cheese, and fish. Because food processing depletes many naturally occurring nutrients, supplementation is key to help ensure adequate intake of this important vitamin.

Vitamin B2 helps support many of the body's systems and is an essential vitamin. Riboflavin is also needed to help the body change vitamin B6 and folate into forms it can use.

Some symptoms of riboflavin deficiency may include:

  • Fatigue
  • Slowed growth
  • Digestive problems
  • Cracks and sores around the corners of the mouth
  • Swollen magenta-colored tongue
  • Eye fatigue
  • Swelling and soreness of the throat
  • Sensitivity to light

Migraine prevention

My doctor recommended 200mg to help prevent migraines. I’ve been taking these 100mg twice a day for about a month. I think I’m getting fewer migraines than I usually would considering my triggers. They do make your pee yellow, but the smell isn’t as bad as B complex.

Alivio de migraña

Lo recibí rápido y bien sellado, tratamiento para migraña recetado por mi médico y han disminuido bastante los dolores de cabeza así que creo que está haciendo efecto
Para mi son fáciles de tragar aunque son un poco grandes, no tengo problemas con eso , el sabor no puedo decir ya que lo tomo junto a otras vitaminas.

Helps my daughter with headaches

My daughter's physician recommended magnesium and Riboflavin (B2) to help her chronic headaches. I've bought this Nutricost brand repeatedly because of the good price, and she reports that it works well. Very reasonable.

Awful taste, pills are huge

For a capsule it had an awful taste to it. This particular brand did not work for what I purchased it for (headaches). The pills were huge; bigger than Tylenol. I will be trying a different brand.

I'm very happy with the results !

Preacribed by my Dr. along with magnesium and coq10 for my abdominal migraines and I am very happy with the results. Have not had a full blown episode in over 18 months. YAY ! !
