Great quality but be prepared to flush

Posted by NaturalMum on May 16, 2013

Beware...if you have not used niacin before this is likely to give you a really hot flush as this is a large dose. I would suggest you start at a lower dose (like 100mg or less) and work your way up to this strength. A niacin flush can be unpleasant if you are not expecting it but once you are used to it, it's quite pleasant and relaxing. I have found niacin to be a saviour for my mood and especially for difficulty going to and staying asleep. I have some niacin before bed and fall asleep quickly - something I've never been able to do!

Quality product!

Posted by Reviewer2156323 on Dec 31, 2012

This is a real quality niacin. The capsules are easy to swallow. My husband and I worked ourselves up to 500mg at a time. Occasionally I still experience a brief flashing but it does not bother me. Do remember to take on a full stomach. For information on proper niacin dosing and niacin saturation visit Dr. Andrew Saul's website at doctoryourself.com

The modern world needs niacin.

Posted by 5378248820893374099 on Dec 22, 2013

From deep depression to feeling normal again, within a week. Yes this product will give you a flush. Yes that is normal. Yes, it t can be unpleasant. But the flush is also beneficial, is part of a healing process, and is by far, not the worst thing in the world. It will also disappear after about a week of use. I have been using Now Foods Niacin for over 5 months now (daily). It is a quality product, and works well. See information from Dr Andrew Saul & Dr Abram Hoffer for dosage information. All mental illness & brain biochemical problems should be dosed with niacin. Also very good for lessening the severity of allergies.

Great Flush!

Posted by Reviewer1403500 on Aug 28, 2013

I like this Niacin the flush was great and the high mg content is superior but it has Magnesium Sterate which sucks so I switched to Jarrow.
