This is a good product!

No problems.

My naturopath asked me to take this. A lot of supplements give me reactions, but this one has not.

One of the Best Online Resources

Natural Healthy Concepts is my favorite place to find the vitamin, herbal and homeopathic supplements I use. They give nice discounts and free shipping to members (membership is free), plus they ship very quickly. Thanks for making my supplement-buying an easy, pleasurable task!

Riboflavin 5 Phosphate

We dont tolerate all Bs yet so is very good to be able to purchase them separately and adjust our dose as necessary. Thanks.
