Does any form of Niacin boost ATP or is it only Inositol hexanicotinate? Fredd started a thread last year about how some people can't take folinic acid (calcium folinate) and must take methylfolate only. This might be a very small percentage of people, but I don't know because it's a long thread and I haven't really read much yet: http://forums.phoenixrising.me/inde...afolin-inducing-deficiency-called-ddtox.9160/ I plan on starting with folinic acid though since most people can convert folinic acid into methylfolate. I don't understand why rich has people taking both methylfolate and folinic acid if folinic acid converts to methyfolate. Since this thread is about different forms of Niacin I thought I should mention that Thorne has another B Complex with extra Niacin (mostly Niacinamide): http://www.iherb.com/Thorne-Research-B-Complex-3-60-Veggie-Caps/18120 There's also 2 other types of Niacin you can take: nicotinamide adenine dinucleotide and NADH (Reduced B-Nicotinamide Adenine Dinucleotide). I'm not sure what the difference between the two are, but NADH is more expensive so I suppose it's more potent.
