MD sees the Results of Niacin

Posted by iHerb Customer on Jan 09, 2007 | Verified Purchase

I am a doctor and I have seen the results of niacin on cholesterol levels. I have a patient that had a lipid panel of trig = 275, chol = 223, HDL = 34, and LDL = 134 and went to trig = 48, chol = 124, HDL = 49, and LDL = 65. This patient was taking liptor previously to adding niacin to her meds.

Thanks for your feedback!

excellent product

Love that it doesn't have a lot of additives or fillers. High quality and cost effective. In terms of the negative reviews about the flush - if you haven't taken a lot of niacin before, definitely work up to this dose - I didn't but then I personally think there are benefits to the flush. But it can be disconcerting the first time. I find the flush is less if I take it with vitamin C.

Needed high strength

Posted by iHerb Customer on Sep 05, 2008 | Verified Purchase

Great product and one of the few high strenght niacin products on the market. Doctor has recommended 3000mg and I find that this is easy to take 3x a day.

This is an excellent product. Most Niacin capsules are full of additives that I'm allergic to. This is just Niacin. I take at the direction of my doctor and since switching to this brand, my total cholesterol has dropped to 126 from 165.

What the doctor ordered

Posted by iHerb Customer on Oct 16, 2006 | Verified Purchase

The only niacin that is as effective as statins to lower LDL and raise HDL cholesterol and safest for the liver is pure crystaline type. Doctor prescribed amounts are in the multigram range (2,000 mg/day for me). Twinlab is by far the best value. The proof is in my very improved lipid profiles.

Thanks for your feedback!

start with a much lower dose

I use this for niacin deficiency. 1/4 of the cap gave me severe flush for 2 hours meaning this is effective and too much for me. I should have started with 50 mg.

HDL Booster

Posted by iHerb Customer on Sep 11, 2010 | Verified Purchase

All my research made it very clear that the "slow release" or "non-flush" Niacin was much less effective and potentially much more toxic. Go with the flush - it takes a few weeks to build up tolerance (start with smaller doses and move up to the Twinlab 500s first), but 2 of these a day boosted my HDL from the high 30s to the low to mid 60s. It has remained at that level for over a year with no detectable effect on my liver function. Exercise alone would never get my HDL much above 40. It doesn't work for everyone though - my wife followed my example, and it didn't change her HDL much at all.

My Go-to Formula

Posted by iHerb Customer on Oct 11, 2015 | Verified Purchase

The flushed skin sensation is something I actually enjoy, and look forward to. It's the very reason I use this form of Niacin – because it dilates the capillaries. And it's the opening-up of those capillaries, which allows increased circulation of nutrients and oxygen. So I take a capsule two or three times a day, depending on the number of meals I eat. I take it with my “Thorne Research Basic Nutrients IV with Copper and Iron,” and other supplements – to insure that my nutrients get delivered to every cell in the body. For that alone – it's worth its weight in gold. But as a bonus, I also find that it's an incredible mood booster, easing the mind and relaxing the lungs – which makes for restful sleep, especially when taken with L-Tryptophan. When I want to rev up my methylation cycle – to increase my cognitive powers, I take a high-dose of methyl-B12 and methyl-folate. When I want to dampen the methylation cycle – for relaxation purposes, this 1000 mg Niacin capsule is my go-to formula.

Powerful stuff

Posted by iHerb Customer on Nov 05, 2010 | Verified Purchase

Use with caution. Serious flushing and other side effects common to too much taken at once. I used only 1 pill but mistakenly took on an empty stomach. I will never make that mistake again. Really high quality. have to take only half a capsule at a time.

Thanks for your feedback!

be carefull with this supplement

Posted by iHerb Customer on Oct 03, 2008 | Verified Purchase

I took this pill to be effective against anxiety and it realy seemed to be effective!!!! However, I have taken many different pills in my life, without being sensitive to side effects. When I took this 1000 mg niacin it gave me a big surprise! I took it after a breakfast and within 10 minutes I started to feel a tingling sensation inside my head and that scared me a bit. It grew stronger and my entire face started to feel like it was on fire, burning! This spread out to the whole body, even my feet. After 2 hours it didn't burn anymore, but I had a red face all day. I googled on it and discovered that this happens more often and is called a niacin flush. In such case one should lower the docis drastically and increase slowly over a 2 week period and then the body will get used to it and the flush will no longer occur. Also I read that such high docis can cause liver damage when taken for prolonged periods of time, so EVERYONE who takes this, don't take a whole pill the first time. I would recommend to open the capsule and just take a quarter for first time.

Thanks for your feedback!
