excellent product for stress.

Posted by iHerb Customer on Jan 23, 2012 | Verified Purchase

this is a great product for stress and fatigue, tried it even late at night and i felt tired sleepy but aware not fatigued or stressed. this b3 form along with b6 coenzymated (p5p) are two of my favourite vitamins on the list, just like b6 p5p probably will feel the tension affects of the first and second dose because your body is getting used to it because before it was used to stress. b6 p5p excellent for swelling of anything in the body also. lion's mane is another product to add for the nervous system stopping jumpy thoughts. pqq is another favourite someday it will be recognized as a vitamin if you want super energy including new limbido energy you never felt before and does something like b3 activate the sirt logevity gene.

Thanks for your feedback!

I normally take nicotinamide, but it makes me really sleepy! This Vitamin doesn't make me feel sleepy at all! I wish all vitamin supplement makers used this form.

Thanks for your feedback!

Helpful sleep aid

These are very effective knock-out tablets for anyone aroused from their sleep. Proactive relaxation!

Thanks for your feedback!

Excellent product

B3 is highly recommended for a number of conditions; including autoimmune like adrenal, MS, and CFS. This form is extremely absorbable and effective; easy to use with the sublingual form, and much more bioavailable. Will keep purchasing. Recommended by credible doctors in my experience.

Thanks for your feedback!

active form of b3

I like this product and recently read that B3 can help REM sleep and help you stay asleep all through the night.

Thanks for your feedback!

Energy Booster

Posted by iHerb Customer on Oct 11, 2006 | Verified Purchase

Since taking coenzymated B-3 I havenoticed a definite increase in energy, especialy in the afternoon when I used to be tired.

Thanks for your feedback!

All serious forward-thing "Vitamin Users" would do well (in my opinion) to partake of this important supplement!

Posted by iHerb Customer on Feb 23, 2017 | Verified Purchase

Whether you're diabetic or a "longevist" (or in-between) you'd very likely benefit from this rather "unique" supplement. NOTE: I wish "iHerb" would carry all of "Source Naturals" coenzymated vitamin-B products in ALL OF THEIR VARIOUS STRENGTHS AND QUANTITIES (just like other outlets do)!

Thanks for your feedback!

Source Naturals, Coenzymated B-3

Posted by iHerb Customer on Apr 04, 2015 | Verified Purchase

I get an immediate noticeable boost when I take this which I do not get from regular forms of B3. I will keep this as a regular part of my regime.

Thanks for your feedback!
