Swanson Vitamin B2 Riboflavin Supplement, Supports Thyroid Function, Energy Metabolism & Healthy Vision, 100 Capsules

I've been taking 200 mg a day for a couple of months now and it really seems to be helping to keep my migraines manageable. It would be nice if it came in 200 mg capsules, but I couldn't find it anywhere, so I just take 2 a day - NP.

Even though Walmart doesn't carry this item in their local stores, I was able to buy it in their online stores. Great deal too!

We were tested at a naturopath office and the Swanson brand products tested "pure"... that was a bit validating of their quality!

I take this vitamin for migraine type headaches along with magnesium. It seems to help.

It's good

I am really happy with these, but wish that they were available in bottles of 300. I take 8 a day, so it doesn't take me long to go through a bottle. As I cannot ship more than 5 bottles at a time to Canada, it means that I have to order more often, which is inconvenient.

My very competent doctor recommended me taking B2. After searching on the Internet and presenting him with various brands, he liked this one the best. The price for this brand was actually less than the ones he did not like as well, which rarely happens.

Good value with coupons. Potent.

The verdict is out yet on this!

After buying two bottles of this product, I learned that naturally occurring B2 will be linked with phosphate and that B2 supplements that label themselves simply as "riboflavin" are a synthetic form of B2. I wish I had known this before I purchased this B2.
