Description

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 insure 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: Does this Nutricost Vitamin B2 contain allergens? Is Nutricost Vitamin B2 Non-GMO? Is Nutricost Vitamin B2 gluten-free? What are the safety and quality standards for this product? I took Vitamin B2 and now I am feeling sick. What should I do? Anything else I should know? These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.

  • Excellent product
Size: 120 Count (Pack of 1)
This is a really good product. Although the capsules are large, it is very easy to swallow them. They are not sticky. I bought this one because the one I used to get with my prescription was finished. So far it has been working well with my magnesium tablets and giving me really good breaks from horrible migraines. ... show more

  • Help for migraines
Size: 120 Count (Pack of 1)
I bought these to try and prevent migraines and tension headaches, and so far it seems to be working. I take one every morning and even though I’ve been under a lot of stress, haven’t had any headaches. I’ve bought other supplements from Nutricost and they’ve all been excellent.
