Does non flushing niacin clean your system as good as regular niacin?

Answer 1

Yes and it is better tolerated.

Answer 2

No, niacin will not help you clear out THC faster than normal. People that tell you so are trying to sell you a product that doesn't even work for what it was originally intended for. Niacin is typically used to help lower unhealthy lipids in the body, but the dose that it normally comes in causes the skin to flush, so they went on to develop a flush-free formula, but it doesn't do anything at all. If someone is telling you it is a wonder drug for this or that they are either trying to sell you something that doesn't work and you don't need, or they are grossly misinformed.
