Niacinamide, 250 mg, 250 Capsules

Using to control neuron-inflammation. No side effects at all, even with 2 capsules 3 times a day. No way to know how effective it might be, but it is a very low price point and seemed to work well in the mice studies where it was placed in the drinking water. Excellent price for this quantity.

There are a few NAD precursors on the market, such as NR and NMN, but unfortunately they are very expensive. Although niacinamide doesn't work as well, it still works. Evidence has shown that 200mg may increase NAD levels by 10%. And it's cheap!
