Review: Very satisfied with my purchase - I really like this niacin supplement. It arrived well sealed and in great condition. The capsules are easy to swallow and have no bad taste. I’m using it as part of my wellness routine and I feel good with it. Great quantity for the price and good quality overall. I would recommend it and would buy again.
Review: Wow! Flushless Vitamin B3. - 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.
