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).

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.
