- Product Information
- Niacin plays an important role in the nervous system, skin health, and mucous membranes. And like many B vitamins, it’s also involved in the metabolic processes that release energy from food.
Our high-strength niacin tablets deliver a full 250mg of vitamin B3, a level that would otherwise be difficult to obtain from your diet alone. Given its strength, we recommend taking our niacin tablets for relatively short periods of up to 4 months – not because of safety concerns, but because the body is unlikely to need this level for an extended period. We’ve also included generous amounts of vitamin B3 in our B50 Complex and B100 Complex should you wish to take those instead.
Niacin is the umbrella term for vitamin B3 since it occurs in several forms, including nicotinic acid, niacinamide, and nicotinamide. We use high-strength, pure nicotinamide in our formula, which we think is the best form to use in supplements.
We’ve chosen to supply vitamin B3 250mg in small, easy to swallow, taste-free tablets instead of capsules as they allow us to deliver highly concentrated amounts of nicotinamide in a convenient, one-a-day dose.
We only source premium raw materials for our niacin tablets. They are made to Good Manufacturing Practice (GMP) in UK factories to ensure the very best quality standards.
This product is suitable for both vegetarians and vegans.

"Good value "By Lezlee , 06 Oct 2025Verified PurchaseOnly started to take these about two weeks ago, but already I don’t seem to be so tired !? Was usually feeling quite lethargic by lunchtime and needed a sit down, but not now. Just hoping that it continues.Recommend to a friend: Yes"more confident"By Patrick Grimes , 13 Aug 2025Verified PurchaseI have done some research on B3 but the noticeable effect it had with me was actually feeling more confident and less inhibited though still quite rational thinkingRecommend to a friend: YesBy Terry Parker , 17 Dec 2024Verified PurchaseEach of these four products have been variously recommended by professional reports. From experience I have confidence in naturesbest''s products. I am 86yrs old and seldom suffer from aches and pains, so can only assume they have the designed effect.
