Swanson Niacinamide is not just another niacin! Although they're closely related and their names are similar, there are some big differences between niacinamide and regular niacin. Both play vital roles in carbohydrate metabolism, helping to supply the entire body with energy, but niacinamide also supports joint health and helps maintain blood sugar already within the normal range.* Plus, niacinamide doesn't cause the "niacin flush" associated with ordinary niacin supplements.

Rated 5 out of 5 by from Superb product Effective, good value! I tried many niacinamide brands before finding Swansons. Wow! I was amazed at the effectiveness! Thank you, Swanson!

Rated 5 out of 5 by from A real lifesaver One of these capsules every 90 minutes during the day and every time that I wake up at night keeps my 76 year old brain sharp as a tack and as focused as that of a young college student. There is never any need to fear those senior moments that can happen in your 60's and 70's. I would not be without my niacinimide.

Rated 5 out of 5 by from No Flushing! I take one of these daily plus Swanson flush-free niacin and have no problem with flushing.

Rated 4 out of 5 by from good, but does not affect cholesterol These are in all ways fabulous, but I just found out that they don't have the positive cardio / cholesterol benefits that straight up niacin has. I read Science Daily on a regular basis, and I should have checked there before going for a low flush option that turns out to be low effectiveness for my purposes.

Rated 5 out of 5 by from great value and it works I was surprised when a B vitamin was suggested for me, since they're usually associated with energy, but since I started taking it, I've been less anxious (not at all).

Rated 5 out of 5 by from Great Product This is great for memory and focus. It also increases my energy level. You can only absorb 250 mgs every hour and a half so I take anywhere from 6 to 12 a day. I
