All FAQs

NMN is a Vitamin B3 (niacin) derivative. It occurs naturally and can be obtained from dietary sources such as fruits, milk, and vegetables. In the body, NMN is used to generate nicotinamide adenine dinucleotide (NAD+)— one of the oldest molecules on earth, found in every cell in our bodies.

Yes. NMN is a direct precursor to NAD+: once absorbed, your cells convert it into NAD+ in a single step. NAD+ is a coenzyme found in every cell.

Our NMN is Uthever® NMN, minimum 99% pure, so you get a pure, high-quality source. Take it in the morning on an empty stomach, ideally with TransResveratrol+.

First thing in the morning, before breakfast, on an empty stomach. That's what our label recommends for both the capsules and the powder.

Your body's own NAD+ activity naturally follows a daily rhythm, and taking NMN in the morning fits that rhythm. Most people find it fits best first thing, so we don't suggest taking it late in the day. For the powder, hold it in your mouth for about 60 seconds, then swallow.

Not in the short term. Our NMN has been tested at up to 40°C and 75% humidity for three months with little or no loss of purity, so it's fine at room temperature, in a bag or while travelling. For the best long-term quality we recommend keeping it in the fridge, especially if you won't finish it within three months.

Both are precursors that your body turns into NAD+. NR first has to be converted into NMN, and NMN is then converted into NAD+, so NMN is one step closer. We sell both (NMN capsules and powder, and NR capsules), so you can choose. Our NMN is minimum 99% pure and tested across 12 data points, including purity, heavy metals and endotoxins, and it's our most popular NAD+ product.

The powder is held in your mouth for about a minute and then swallowed; the capsules are swallowed with water. Both work, so it really comes down to what you prefer.

For best results we recommend to take NMN first thing in the morning on an empty stomach, whether taking the capsules or the powder form. If you are taking the capsule form we recommend to take them with a glass of water. If you have opted for the powder form, hold a scoop (or 2 scoops, depending on your recommended dosage) in your mouth for about a minute, then swallow. If you find the taste slightly sour, you can mix the powder in a glass of water. After taking NMN (powder or capsule version) please ensure to wait at least 30 minutes before having any food or drinks, except water.

Consistency is key! We suggest making NMN a daily part of your morning routine and taking it consistently over several months.

Rigorous Testing + Quality Guaranteed

In a market where 1 in 3 NMN products have been found to contain less NMN than labelled (and some contain none at all) purity isn't a nice-to-have. It's the whole point.

Every batch of Youth & Earth NMN is independently tested for purity and held to a standard that goes beyond what most brands test for.

Two Simple Formats

We offer NMN in two formats so you can choose what suits your routine: a powder you hold in your mouth for about a minute before swallowing, or capsules you swallow with water.

Both contain the same minimum 99% pure Uthever® NMN, with nothing else added.

Ingredient Sourcing

Our NMN is a single, pure ingredient — β-Nicotinamide Mononucleotide at 99%+ purity. Made to strict purity standards with no fillers, additives, or unnecessary extras.

We evaluate every manufacturing partner against strict U.S./EU benchmarks, with detailed Certificates of Analysis confirming both purity and potency.

What's on the label is what's in the capsule.

Testing Partners

We centralise third-party verification through leading accredited labs, including specific endotoxin testing — a contamination risk flagged by leading longevity researchers that most NMN brands don't test for at all.

We are onboarding all products to semi-annual reporting so customers can access results directly, with full line coverage planned to provide 100% confirmation across safety metrics, including heavy metals, pathogens, and purity.

Because transparency isn't just a value, for NMN, it's the differentiator.

Definitely recommend trying this product

The quality of the NMN is equal to the proficiency and professional service. Simply the best! I have researched and sampled several by different companies and have found them to be far in the rearvies to Youth and Earths NMN.
