"Excellent product improves memory and helps clear away brain fog that may accompany advancing years." ~product review by RobertoM

  • A versatile form of vitamin B-3

  • Aids carbohydrate metabolism to provide the body with energy

  • Supports joint health

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. Plus, niacinamide doesn't cause the "niacin flush" associated with ordinary niacin supplements.

Niacinamide 4.7 5 13 16
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. December 11, 2013
Great product I've been taking Swanson's niacinamide for over 10 years. It's a good product at a great price. December 4, 2013
Seems to work very well for us. November 8, 2013
My Favorite Supplement The longer I am taking Swanson Premium Niacinamide the better I feel. My expectations have been greatly satisfied. March 10, 2013
Clears up brain fog Excellent product improves memory and helps clear away brain fog that may accompany advancing years. March 6, 2013
Good value This product does not cause a flush and is convenient to take. February 25, 2013
Swanson Premium Niacinamide This does not seem to be as effective as plain niacin. October 10, 2011
Good Product Another good value by Swanson. Top quality, good information, easy to use site. June 24, 2011
No Flushing! I take one of these daily plus Swanson flush-free niacin and have no problem with flushing. July 7, 2010
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. March 5, 2010
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). February 5, 2010
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 September 23, 2009
Nicinamide I take it before going to bed for morning stiffness. I have recommended it to others and it helps them also with morning stiffness. July 30, 2009
