Quality and Purity I Trust
Posted by Reviewer2025838 on Dec 18, 2011
I love the Thorne brand and thought I'd try these. I've been cycling different B vitamins to see if any had an effect on my sleep, mood and memory. The one that actually helps is Vitamin B1 (Thiamine) which my research shows is easily blocked if you consume tea or red wine with meals (both contain tannins which block B1 absorption).

Had changed to a cheaper version of riboflavin (and R5P) but much prefer this product. Helps when I get cracked lips and watery eyes.

easy to take in one capsule - active co-enzymed form of vitamin B6.
Thorne Research's Riboflavin 5 Phoshate
Posted by Reviewer2559753 on Feb 04, 2011
This is a difficult product to find in veggie caps. So I was very pleased to find iHerb had it. And both me and my husband have so much more energy when taking this extra Riboflavin in addition to our multiple vitamin. Yes, I would recommend taking this product in addition to a regular multiple vitamin fomula. In Florida

I like using the active forms of B vitamins, like this form of B2 rather than forms that are cheap, but not found naturally. This one is priced reasonably too, and I trust Thorne to make quality products.
We use it all the time

This is active form of Riboflavin, and it is not very expensive, so we use it.

It has stopped my eyes from feeling 'gritty' and a bit sore. The eye redness has gone too. I only take half a tablet each day (sprinkle into water) so the bottle will last a while too.

This is a riboflavin I actually seem to be able to tolerate.

I only take activated B vitamins now as the synthetic forms just do not work for me. This is the first time I have tried this brand & am very happy.
