Riboflavin Dietary Supplement Nurticost® Quality Guaranteed Third Party Tested GMP Compliant Facility Non-GMO Product Gluten-Free 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, or riboflavin, is a member of the B vitamin family which your body uses to build red blood cells. Red blood cells carry oxygen and nutrients to our muscles. It also helps break down proteins, fats, and carbohydrates, serving a vital role in maintaining the body’s energy supply. For this reason, people suffering from low vitamin B2 often complain of fatigue. Vitamin B2 is also commonly used to treat migraine headaches.

Works for Headaches and Migraines
My neurologist recommended I take 400 mg of B2 daily for my headaches and migraines. I have been taking these consistently for a few months now (along with a whole food multivitamin) and it has cut down on my headaches and eradicated my migraines. I am hoping this continues to keep them at bay.

great
As someone who has struggled with the disorienting and debilitating symptoms of Vestibular Migraine (VM) , I'm always on the lookout for effective prophylactic treatments. I was sceptical but hopeful when I started taking this, which is marketed as a supplement to help with VM symptoms. After taking it consistently for some time, I can confidently say it has made a remarkable difference.

Vitamin B2
Good dosage and quality for a reasonable price. I’ve been taking it for 3 months and I see improvement in my nervous system. Taste is fine, nothing strong or strange.
