If your body shows higher levels of a molecule called NAAD after taking NR or NMN supplements, it might mean your body is using a special pathway that only works with niacin (nicotinic acid) to make energy molecules.

The differential impact of three different NAD+ boosters on circulatory NAD and microbial metabolism in humans

Randomized Controlled Trial

The study shows that NR and NMN supplements are turned into nicotinic acid by gut bacteria, which then boosts NAD+ through a specific pathway, just like the claim says.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

Even though taking NR or NMN boosts a molecule called NAD+ in the blood, we don’t actually have solid proof it makes people stronger, healthier, sharper, or more energetic.

Taking NR or NMN supplements by mouth seems to boost a key molecule called NAD+ in your blood, which scientists think might be good for aging, but we don’t know yet if it actually makes a real difference to health.
