ProHealth Longevity Supplements | NMN, Resveratrol, AKG

A brand built around cellular ageing

ProHealth Longevity has sold nutritional supplements since 1988 and now concentrates on one theme: cellular ageing. The range centres on NMN (nicotinamide mononucleotide), a compound related to vitamin B3 that the body uses to make NAD+. NAD+ is a molecule cells need for normal energy metabolism, and levels fall as people get older. Around that core sit ingredients people often take in the same routine: trans-resveratrol, TMG (trimethylglycine), calcium AKG, astaxanthin, molecular hydrogen tablets and NADH with CoQ10. It sits among the more specialised brands we carry.

What makes this catalogue unusual is the depth in a single ingredient. The same branded NMN raw material, Uthever, runs through capsules, loose powder, lozenges that dissolve in the mouth, sustained-release tablets and liposomal versions. Liposomal means the ingredient is wrapped in a tiny fat layer, which is meant to improve absorption. The brand states openly that only capsules were used in its human study and that the formats have not been compared against each other. We repeat that here, because it changes how you should choose: pick the format you will genuinely take every day.

Who this range fits

This is a specialist range, not a first step into longevity supplements. It suits you if the basics are already in place and you want to add something specific.

You want a single-ingredient NMN with a named raw material and a batch certificate you can check.
You prefer powder so you can weigh your own dose and adjust it.
You already take trans-resveratrol or TMG and would rather have them in one capsule.
You dislike swallowing capsules and want a lozenge or an effervescent tablet instead.

Why we stock ProHealth Longevity

We judge a brand on three things: the ingredient form, the dose, and whether the combinations make sense. ProHealth Longevity earns its place because it names its raw material instead of hiding behind a blend, publishes batch testing by independent laboratories, and doses in amounts that match the studies it points to. It is not a cheap range, and we would rather say that than dress it up: you are paying for a traceable ingredient, not a bigger scoop. We buy directly from the brand, so every jar is authentic, and our compliance team checks each product before it goes live. You can read how we select brands.

What to expect, honestly

The European food safety authority (EFSA) has approved no health claims for NMN, trans-resveratrol or calcium AKG. So we describe what these ingredients are and how they are dosed, and we leave the promises to others. If you want options with a longer research history behind them, products with coenzyme Q10 are the more established route; see our coenzyme Q10 selection. Whichever you choose, give it two to three weeks of consistent daily use before you form an opinion, and take it at the same moment each day so you do not forget. One practical detail that catches people out: NMN powder is sensitive to moisture, so keep it sealed in a cool, dry cupboard rather than the bathroom.

ProHealth Longevity is an American supplement brand that has been selling nutritional products since 1988. Its current range is built around cellular ageing rather than everyday vitamins. You will mostly find NMN, trans-resveratrol, TMG, calcium AKG, astaxanthin, molecular hydrogen tablets and NADH with CoQ10. The brand names its raw materials and publishes independent batch testing, which is the main reason we carry it.

One area: ingredients linked to NAD+, a molecule your cells use in normal energy metabolism. NMN is the anchor product, and the rest of the range is designed to sit alongside it. Compared with a broad multivitamin brand, the catalogue is narrow but deep. That matters when you are choosing: you get many versions of the same ingredient rather than one version of many ingredients.

Uthever is the trade name of the specific NMN raw material the brand uses in its products. Naming a raw material is useful for you as a buyer, because purity in this category varies a lot and cheap NMN has a poor reputation. A named material can be traced to a certificate of analysis for that batch. The same Uthever material is used across the different formats in the range.

There is no measured absorption ranking between these formats, so choose on habit and dosing control rather than on a promise of better uptake.

Form	How you take it	Suits you if
Capsules	Swallow with water	You want the format used in the human study
Powder	Weigh and mix in water	You want to adjust your own dose
Lozenge	Dissolve in the mouth	You dislike swallowing capsules
Sustained-release tablet	Swallow, releases slowly	You prefer one dose per day
Liposomal	Capsule or liquid	You already use liposomal products

The brand suggests taking NMN in the morning with food, and that is a sensible default for two reasons. Food can soften any stomach discomfort, and a fixed morning slot makes the habit easier to keep. Consistency does more for you than perfect timing. If you split a powder dose, keep both moments at the same times each day so your routine stays simple and repeatable.

These three appear in the same combination products because they sit near each other in the same cellular pathways, and many buyers were already taking them separately. Putting them in one capsule reduces the number of pills. Be clear on the limits: EFSA has approved no health claim for this combination, so we present it as a convenience choice, not a proven multiplier. If you prefer to dose them apart, browse our trans-resveratrol options.

Look for three things on any NMN product. First, a named raw material rather than a vague blend. Second, a certificate of analysis for the batch, covering purity, potency and heavy metals. Third, an independent laboratory doing that testing, not only the manufacturer. ProHealth Longevity publishes batch certificates, and we add our own layer: we test products ourselves and independent labs spot-check batches before and after they go live.

Yes, and it is worth understanding. In Great Britain, ingredients without a history of food use need authorisation under the novel foods rules before they can be sold freely as food supplements. NMN has no such authorisation, so availability, labelling and shipping can differ from the American market. Claim language differs too: American pages may talk about reversing biological age, while in Europe only claims approved by EFSA are permitted, and none exist for NMN.
