Excellent Natural Alternative to Lipitor or other Statins

Posted by Reviewer2753195 on May 21, 2017 | Verified Purchase

This product is a great natural alternative to use for lowering cholesterol. My physician prescribed Lipitor, more drugs as we age. Did some research and decided to use this Niacin, instead and it's great with no harmful side effects! My cholesterol is quickly lowered and I'll continue to buy and use to manage and maintain healthy cholesterol levels. I recommend one struggle with aging and also receive news of elevated levels of cholesterol should try Niacin which I'm certain Lipitor has other negative side effects. As an example, such as the breakdown of skeletal muscle tissue, leading to kidney failure. This condition may be more likely to occur in older adults and in people who have kidney disease or poorly controlled hypothyroidism (underactive thyroid).

Next time I'll get the flush

I've found these OK but didn't realise they were the non-flush variety. Feel as though this is a synthetic Niacin and not the real deal but will use them up in any case

Thanks for your feedback!

Yeah, my doctor had me on slo Niacin but I got killer flashes. This stuff apparently metabolizes into Niacin but even the large dose (500mgx2) doesn't cause the flashes. Dr says it's OK.

Thanks for your feedback!
