Product Overview


  • Dietary Supplement
  • Nicotinamide Adenine Dinucleotide

Nicotinamide adenine dinucleotide (NAD), is one of two main metabolically active forms of vitamin B-3. The other is NAD phosphate (NADP). NAD is a prominent coenzyme in the brain, where it helps to generate the massive energy that the brain requires for its normal function. NAD is necessary for many stages of converting food into energy and in alcohol metabolism.

The Benefits of Coenzymated Sublingual Vitamins

In order for vitamins to be utilized by the body, they must first be converted into their active coenzyme forms. Source Naturals Coenzymated B-3 goes directly into your bloodstream in its active form, ready to go to work immediately. This avoids the loss that may occur not only during digestion, but during the liver's conversion process as well.

Suggested Use

1 tablet daily. Place tablet under the tongue and allow to dissolve slowly, altering the position of the tablet to avoid prolonged contact with the same area.

Other Ingredients

Sorbitol, mannitol, natural peppermint flavor, and magnesium stearate.


Note: If you are pregnant, may become pregnant, or breastfeeding, consult your health care professional before using this product.

Do not use if either tamper-evident seal is broken or missing. Keep out of the reach of children.

Source Naturals, Coenzymated B-3

Posted by Reviewer2167095 on Apr 04, 2015

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.

Took for CFS

Posted by Reviewer2177198 on May 10, 2014

No improvement noticed. Didn't help me get back to sleep either when sometimes waking during the night. It tastes nice. I've heard it's the new longevity sup, but decided to not reorder as I'm taking a lot of other sups. I wouldn't have a problem with taking handfuls of sups if they were made smaller. They're nearly all too large and I get sick of swallowing a handful of pebbles everyday! Sups in Thailand are half the size of the average US ones, which have too many fillers.

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

Excellent product

Posted by Reviewer1141113 on Feb 01, 2013

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.
