Great sleep and mood aid, split the tablets to get the dose you need

Posted by NaturalMum on May 16, 2013

This is a great way to start of with a flushing form of niacin. Split the tablets to begin with and work your way up to a whole. I love these tablets, great just before bed to ensure sleep and really great for the problem I have in waking up in the middle of the night and not getting back to sleep. I just have one of these and I'm back asleep in no time. Niacin is also great for mood disorders and cholesterol...do some research and you'll be amazed that this nutrient isn't more widely taken. I found this brand to have the strongest flush for its strength which I believe is an indication of a quality niacin supplement.

forget statins, take niacin and save (money and health)

Posted by Reviewer2532737 on Jun 14, 2008

a good price. I avoid the more extensive non-flushing, some forms of non-flushing are riskier at high dosages according to a Veterans hospital study. Taking niacin is as effective, cheaper, and safer than taken those nasty statin drugs that give you muscle weakness. Don't be a sucker, endure a little flushing each day to keep those arteries clean.

My doctor wanted me to take statins for high cholesterol, since those are know to casue liver and kidney damage, I flat out said NO. I found (on a gov website) that Naicin was 30% MORE effective at reducing high cholesterol than statins. My count went from 270 down to 196 in 6 months. The 100mg size is just the right amount, (very minor or no flush occurs). Note: If you have a major flush lasting longer than a minute or two, your taking too much, (per a recent doctors study thats available online) Take AFTER a FULL meal!!

Best low dose niacin

Posted by cot477 on Jul 03, 2012

After reading Hoffer's book on niacin we became nightly users. Read the book! We were using a different brand - using a tablet cutter to dose it lower - 25mg for my child and 50mg for me. The other brand would break and crumble. Source Naturals is made slightly thicker (more binders, but that's ok) and it cuts perfectly. I feel confident in the dosing of this tablet. We've already placed another order...

not as 'flushy' as capsules

Posted by Reviewer2197931 on May 20, 2009

These are tablets - they are not as fast-acting as capsules. My last niacin was capsules which caused more flushing at 200mg doses. These I am taking 750mg at a time and tolerating easily.
