Still assessing but supplier is excellent

Just started taking this product. This is the non-flush niacin. I am using this product to see if it can provide support for insomnia. It is too early to know if there is any benefit but will continue to use and assess. Be mindful of dose levels if you take any supplements. I have used this supplier/manufacturer on many products and have been satisfied with the quality and value on those products.

Vitamin B3 Be Great

Vitamin B3 is an essential component of the Vitamin B family. It is found by itself in certain supplements but is nearly always a part of any good B Complex Supplement. At InternationalOrganix.com, we use it in our B Complex that goes into several of our natural supplements including our revolutionary new Pain Refrain line of pain management supplements. Bulk Supplements makes great single-ingredient supplements. Walmart has great prices and very fast shipping. And InternationalOrganix.com make the best natural cures and treatments for your most important healthcare needs. Give us all a try.

Effective anithistamine

Works for lowering cholesterol and/or as an antihistamine. Many years ago, I used niacin to lower my cholesterol. Now I use it as an antihistamine. One gram dissolved under my tongue and the histamine flushes out of my system.
