Sometimes you wonder just how much vitamins make a difference (especially more accessible brands like NOW)... but this definitely reminded me they do! Unbeknownst to me I was dealing with a vitamin B2 deficiency - revealed by labs. I took this for a while and then got out of the habit after running out. Months later... I began having really terrible symptoms, including a really, really sore tongue. So sore it hurt to eat or talk! It didn't take me long to link back to this. I began taking B2 again... and within TWO DOSES the weeks of painful symptoms began to reverse. Really incredible. Been much more faithful with my protocol since this whole thing. Also - grateful iHerb offers such good prices AND a low shipping threshold!

Perhaps my favourite B vitamin, though the entire complex is so important it's like choosing your favourite child!Riboflavin has been shown to significantly reduce headache frequency at 400 mg/day. I have found this to be true at lower dosages (100-200mg). Riboflavin can reduce homocysteine levels and blood pressure.Riboflavin deficiency has profound effect on iron absorption, metabolism of tryptophan, mitochondrial dysfunction, gastrointestinal tract, brain dysfunction and metabolism of other vitamins as well as is associated with skin disorders. The last point was key for me as it is involved with the metabolism of other B vitamins. I tend to take it in smaller doses throughout the day as I believe it has an upper limit of absorption.

I have not tried it yet. I had a Now product before, so I trust this brand. Vitamin B2 can protect our nervous system. It boosts our metabolism. If you take it with folic acid, it will be absorbed faster. Vitamin B2 soothes mouth ulcer, migrant, conjuctivitis and virgina irritation. The effect is visible.

Good quality Riboflavin. I considered the riboflavin-5-phosphate form, but then found out that plain riboflavin form maybe better absorbed in people with gut issues (The 5-phosphate form needs cleaving of the phosphate group before absorption, which may be impaired). So this might be better than the pricier ones. These capsules have the natural riboflavin yellow colour and are ve rage sized - quite easy to swallow. I had a good boost of energy overall when used as part of a nutritional protocol (with thiamine, riboflavin, niacin and vitamin c). I got partial relief from premenstrual headaches too, though I didn’t go to the 400mg dose recommended in some migraine protocols (I took 100 mg/ day). Planning to increase dose by 100 mg next month.
I take vitamin B2 regularly for the last 1.5 years. It helps me with my histamine issue. This NOW brand I believe has good quality. But even that I always make sure to rotate between this brand and a few other brands.I also like the potency - 100 mg is just right. I can take it a few times a day. When I don't need it as much, I open up the capsule and just take half of the content as needed.I don't find the taste horrible at all even though I have read people said it's bitter. For me it's not the worst I have taken.
I take 400 mg of riboflavin vitamin B2 to help reduse migraines. I take 200mg in the morning and 200 mg in the evening. I did feel a slight increase in migraines when I switched to this brand but overall they did work good! Since I started taking 400mg of B2 my migraines have been reduses by 80 percent monthly. Ones I tried a brand that contained 400mg in one pill however that absolutely did not work for me. I need my dosis spread durring the day for it to work. The pills are not to big and the have no taste. They do turn your pee yellow but that is about all the side effect that I can think of. The package arrives really fast to the Netherlands!
Excellent Vitamin B-2 from Now Foods. Riboflavin (vitamin B-2) is one of the most important water-soluble vitamins. Riboflavin is stable in an acidic environment and rapidly degrades in an alkaline environment. Riboflavin is an enzyme cofactor required for the production of energy from carbohydrates, fats, and proteins. In addition, it is necessary for the formation of red blood cells, antibodies, for the regulation of growth and reproductive functions in the body. It is also essential for healthy skin, nails, hair growth, and overall overall health, including thyroid function. I recommend this supplement.
