Ronald Osborne´s Life Extension Vitamin B3 Niacin 500 mg Review
Posted by RonaldOsborne on Oct 27, 2012
Great alternative to the brand I usually use I ran out of niacin and my skin was beginning to suffer with Eczema again. Life Extension Vitamin B3 is every bit as good as my usual brand. When buying niacin. This product is strictly B3 and it will make you flush, but that is a normal side effect and if you take in in small doses and build up to the correct dosage the side effects do eventually go away. I recommend this product to anyone who needs to take a Niacin supplement, is definately the best I have used.
