even taking it direct after eating it gave me a strong flush. I felt itchy and shivery, like I had flu, and then really sleepy. Definitely knocks you out for sleep although you do wake up in the middle of the night. Not sure what to make of it but obviously doing something!

I take 1 twice daily. My HDL is high, my triglycerides are low and my LDL is lower but still above the "recommended " level. I feel sure if I took a higher dose my LDL would fall further. I don't bother because sometimes I still get flushes.I've been taking for a few years now.

Fountain of Youth..

Posted by 4871457256774475382 on Apr 05, 2015

My GP tried to put me on statins for high cholesterol about 2 yrs ago and after researching the topic I decided I would stick to the 'gold-standard' of lipid control Nicotinic acid. I have lowered the bad and raised my good cholesterol significantly, which statins alone cannot do. Also B3 has other benefits on the blood vessels and circulation. Side effects occur only after the first dose a.m which I take in bed and the next dose has no side effects. Also as an exercise mimetic Niacin has contributed to significant weight loss and greater energy levels.It should be taken in conjunction with the whole B vitamin family for best results. Ofcourse everyone should discuss with their doctor prior to self-prescribing.
