My husband takes this religiously for sneezing, running nose, and itchy eyes. He hasn't taken the deep dive to work on his gut issues like I have, so this product is the next best thing. I used to take it before making some massive changes in my diet and gut, so I don't need it much, except for occasionally and it still works like a charm. Just 2 pills and usually won't need anything again, but my husband will take 2 pills 3 x/day when the pollen is high and he doesn't have to take anything pharmaceutical. I think this could be helpful for MAST cell activation if that is an issue.

Also known as nicotinic acid, niacin is an essential nutrient, positioned at the core of NAD/NADH and NADP/NADPH, which are major redox-active "electron storage" compounds. One or both of these "redox pairs" is involved in every major biochemical pathway.
