Endurance ProductsENDUR-ACIN, Extended Release Niacin for Optimal Absorption & Low-Flush Vitamin B3 Niacin 500mg, Premium Niacin Supplement Made in USA, 200 Tablets

This is my second purchase of Endur-Acin and I am extremely happy. I have been looking for a form of Vitamin B3 that is "flush" free and this is the one because it is truly nicotinic acid which is the only type of niacin that targets heart health and lipid metabolism. It is coated in a vegetable wax that results in it breaking down slowly thereby avoiding the flush and I have not experienced any stomach upset either. I bought 500mg and have found it very effective in boosting my brain function while recovering from a broken neck (2021) where morphine was used daily. My memory was severely affected but when I was released from the hospital 4 months later I stopped the morphine cold turkey because I needed to rebuild my memory. Using many different supplements things were slowly getting better but when in late 2024 I finally began Endur-Acin surprisingly quickly things turned around. Within the first month a brightness and clarity had surfaced and progress is continuing. I would highly recommend it to anyone needing the benefits of nicotinamide. I was unsuccessful in achieving my goals with other types of Vitamin B3.

So, apparently, "no-flush" or "reduced flush" doesn't have the same health benefits as the kind that makes you feel like you're dying, but the "full flush" niacin made it look like I was 70 years old (I'm 43) with blood vessels popping out of my head.This time-release has MORE of the benefits than Niacinamide which is about the same as taking ascorbic acid instead of eating an orange (it's incomplete). Since it's real Niacin, in a large dose you WILL get some flushing, just less. The release is delayed so you are less likely to overwhelm your liver which will cause gout to flare up since uric acid can't be filtered out of your blood.In my case I have gout AND really flushing on just 100mg of straight Niacin so this is the best I can do. I have something wrong with my vascular system and this reduces the symptoms. Talk to your doctor before starting, stopping, or changing the type of Niacin you take as the effects on the body can be extreme, especially at high doses.

I have these on subscription as per my presciption requirements. Good vaue for money, easilt tolerated.

been taking for awhile and all seems to be good

Easy to swallow and digest. Very little flushing.

Do they really work? Or are they a placebo? That's the big question, and personally, I don't care. To test them, i went without for about three weeks and noticed a difference in the way I was able to recall names, etc. So, I'm taking one daily and feeling good about it.

Have been using this for 3 years since doctor recommended taking it before bed.

The closed lid of the product was deformed before it was opened, I wonder why?
