Nutricost Vitamin B2 (Riboflavin) 400mg, 120 Capsules - Gluten Free, Non-GMO

Good stuff but it was so good that my pee turned green for several urinations afterward. I know it was from the B2 as I didn't take anything else and it went away because I stopped taking it. Use sparingly... I found that this is not uncommon as B2 fluoresces under UV light.

I purchased this item to treat angular cheilitis which is mouth dryness and it worked! I can say that in a week’s time I am no longer getting dry cracks lips. I received my order promptly on the first day ordered. Great service and great product. Thank you

I deal with migraines and Vitamin B2 was recommended by my neurologist. It has absolutely helped prevent and lessen the headaches and I couldn't be happier with it. Great!

It didn’t upset my stomach and I am very sensitive to pills, however make sure it’s what you need in your daily vitamin intake as it would upset kidney if taken with other vitamins supplements, best to take when you know you’re lack of this vitamin B2, skin health? I didn’t take it long enough to give you full review as I’m in process healing from respiratory infection, and watching vitamin intake.

Great for preventing headaches. Easy to swallow.

I couldn't find these ANY WHERE! So happy Amazon has them and I absolutely feel a difference in my body. Taking these with the magnesium works wonders for sleep and overall health!

Take it everyday reorder when I run out!!
