I have tried other niacins. I like this one. It is effective ingredient and a trusted product. I have bought other Natural Factors items and their brand is very effective and quality. I trust this company.That is good product my nervous system and bodies reaction no niacin flush.Niacin is necessary for protein metabolism, energy production and normal nervous system function
Great supplements, I just think the dosage is too high for me. I use one every other day. I will buy the 250 mg capsules and try to take them daily. In any way, I am satisfied with the quality, I feel more energy. Prefect capsules size
Bought this for my daughter and it works as described and the no-flush niacin is exactly that NO FLUSH. She loves that! It helps with her mood swings, especially mild depression. Great value even when compared to big-box store brands.
the product was delivered quickly. the tablets have a pleasant size and, contrary to other products of this type that have already been tested, no side effects such as heat or a racing heart occurred. great product at a good price.
