************* Great product -- PLEASE CONSULT YOU DOCTOR

I have been using this product for a year after switching from GNC's niacin (B3). GNC's product was good, but very expensive. I no longer experience the 'Niacin Flush' that people are complaining about. Before taking any megadose supplement/vitamin, you should CONSULT YOUR DOCTOR. Taking large doses of vitamin B3 (niacin) requires you to have good liver function. If your liver function is poor, you could permanently damage it. My doctor specifically told me to STAY AWAY FROM THE ''NO-FLUSH'' NIACINAMIDE. I hope this review helps some people to realize that taking megadoses of niacin should be taken with an informed consent, and the green light from your doctor. . . . . You can find other products I use on my Page! I use only products that have Scientifically Proven benefits.

I take niacin at 500mg/day for the last two months. It has helped me to increase HDL, nad lower LDL and triglycerides. Also, niacin is the only supplement that has proved to decrease the thicknes of atheromatic plaque. My 14 yo son takes the same amount to help his acme. After one month, results are really impressive. We both flash, but it is not that bad. As a matter of fact, we enjoy it.
