The research behind the ingredients

NMN · Clinical trial

In a 60-day randomized, placebo-controlled trial of 80 healthy middle-aged adults, NMN raised blood NAD+ concentrations compared with placebo, was well tolerated, and was associated with longer six-minute walking distance.

NAD+ · Review

This review explains NAD+’s central role in cellular energy metabolism and maintenance, and summarizes evidence that NAD+ levels decline with age in multiple tissues.

Read the source

Creatine · Meta-analysis

Pooling 16 randomized controlled trials, researchers found creatine supplementation was associated with improvements in memory, attention time and information-processing speed in adults.

Frequently asked questions

What is NAD+, and why does it matter?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell. Your cells use it to turn food into energy and to run everyday maintenance processes. Research shows NAD+ levels tend to decline with age.

Do I need the NAD+ test kit to buy this?

No. The test kit is sold separately and is optional. Some people like to test before starting and again about 4 weeks in, to see how their body responds and adjust.

Is this the same as Zyndio’s prescription NAD+ therapy?

No. This is an over-the-counter dietary supplement. Zyndio’s prescription NAD+ nasal spray and injections are a separate program that requires physician review.

Is the chewable as strong as the powder?

Yes. Each tablet has the same 1,000 mg formula as one scoop of the powder.

Why dissolve it under the tongue?

Dissolving it slowly is simply how this lozenge format is designed to be taken. If you’re in a hurry, chewing it is fine.

Nutrition and prescription care are separate.

These supplements are over-the-counter products and are not prescribed or physician-reviewed. Zyndio’s prescription NAD+ therapies follow a separate physician-reviewed care pathway.
