Great for growing your mitochondria! Power production cells in your body!
Niacin is a great addition to my already healthy & nutritious diet. However, based on the average American diet and the Corporate Assault on humanities wholesome food supply via "PROCESSED FOODS". Fake Food with the same taste but nearly no nutritional value or nutrients. That os what we get for allowing corporate America to run amok! NGO's being the worst offenders and violators of American's trust. NGO's must be abolished across the board!

Life Extension Niacin
Life Extension vitamins are excellent quality. The non-flush niacin works great and it doesn’t make you feel hot or produce any red blotchy marks. I have used it for years and I recommend it highly. It doesn’t produce any upset stomach. It’s easier to swallow and it improves my energy level as well as my circulation. It’s a no brainer.

No flush and my cholesterol dropped!
I boought this in June 2024 and I started taking it faithfully every day after breakfast. I had my labs drawn in Sept and I noticed my total cholesteral and LDL dropped 31 points since my last check in March of same year. I do not get a flush from this product. Prior to usuing this, I tried a long acting Niacin but that gave me a strong flush after a few days of using it so I stopped it. I tried this and I am satisfied with the product so far. Hence, I will be sticking with this Life Ext product for now. If anything changes, I will update.
