Longevity supplements have moved from niche biohacking forums into the mainstream, and NMN (nicotinamide mononucleotide) is one of the most discussed. It is a precursor to NAD+, a molecule involved in cellular energy that declines with age. Youth & Earth has built its store around NMN, then added complementary products such as resveratrol, CoQ10, creatine and liposomal formulas.
We looked at the range, the quality claims and the guarantee, and at how much the science actually supports these products today.
About Youth & Earth
Youth & Earth is a UK-focused supplement brand that ships to UK addresses only and prices in pounds sterling. Its catalog is built around healthy aging and cellular energy, and it emphasizes purity: products are made in GMP facilities and backed by third-party testing for heavy metals, microplastics and pathogens, according to the brand.
Note that while this store appears in our sleep section's research, it is primarily a longevity supplement brand. Its nighttime product, PM: Sleep Dust, is one small part of a wider range.
The product formats are designed to slot into a daily routine: capsules for simplicity, powders for flexible dosing, chews for creatine and liquid liposomal formulas for people who dislike swallowing pills. Liposomal products wrap ingredients in tiny fat-based spheres, which the brand says supports absorption.
The core range
- NMN Capsules: 99% pure Uthever NMN in 250 mg or 500 mg capsules, from £32.99.
- NMN Powder: the same ingredient in 15 g, 30 g or 100 g pouches, from £37.49.
- TransResveratrol+: trans-resveratrol with quercetin and curcumin plus BioPerine, at £39.99.
- Micronised Creatine Chews: 5 g of creatine monohydrate per two chews, from £26.99.
- Liposomal formulas: including liposomal glutathione (400 mg per serving), spermidine and hyaluronic acid.
- Other products: V14 Longevity Reds, Intelligent Iron, Berberine+, PEA, Preservage and PM: Sleep Dust.
Choosing a starting point
If NMN is why you are visiting, capsules are the easiest way to start, and the 250 mg dose is a sensible first step. Powder works out cheaper per gram and lets you adjust the amount, but needs measuring. If you exercise regularly and want something with stronger evidence behind it, the creatine chews are the most practical product in the range. The liposomal and botanical products are better treated as optional extras once you know what you want from a routine.

Bundles and stacks
Youth & Earth encourages stacking. The Cellular Energy Bundle pairs NMN with TransResveratrol+ from £62.04 (a 15% saving), and the Cellular Energy Stack adds CoQ10 from £87.98 (a 20% saving). There is also an AM & PM bundle that combines a daytime product with the nighttime formula.
Bundles are good value if you are confident you want every product in them. If you are new to these supplements, it is wiser to start with one product, such as NMN capsules, so you can tell how you respond.
What the science says
NMN raises NAD+ levels in human studies, and research into its effects on metabolism, muscle and aging is active. However, large, long-term trials showing clear health outcomes in people are still limited. The same applies to resveratrol and spermidine: there is interesting early research, but the evidence does not yet support strong claims. Creatine is the exception in this range, with a well-established track record for muscle and exercise performance.
It is also worth knowing that NMN's regulatory status varies by country, and rules have shifted in recent years. Buy for curiosity and personal experimentation, with realistic expectations, rather than expecting to turn back the clock.
Pricing, subscriptions and the guarantee
Single products range from about £26.99 to £39.99, with bundles up to £87.98. Subscribe & Save takes about 20% off, while first-time customers can get 15% off a one-off order, though that code cannot be combined with subscription discounts. UK delivery is free over £50.
The 60-day money-back guarantee is a plus, but read the terms: there are exclusions, including at least one large NMN powder size. Check the product page before buying anything in bulk.
Price per serving is listed alongside many products, which makes it easier to compare capsules with powder. As a rough rule, larger sizes and subscriptions bring the cost down meaningfully, so once you know a product suits you, switching to a subscription is the simplest way to save.
Who it suits, and who should skip it
Youth & Earth suits UK adults interested in healthy aging who want a clean, tested NMN product and are comfortable paying for a developing area of science. It is not ideal for people outside the UK, anyone on a tight budget, or shoppers who simply want a basic multivitamin. If sleep is your main concern, a targeted product such as Som Sleep or a non-supplement approach like a blackout mask may be more useful.
Our verdict
Youth & Earth is a credible, quality-focused longevity brand with sensible prices for its category and a helpful subscription discount. We rate it moderately because the evidence for its headline ingredients is still emerging and the guarantee is not unconditional. Start small, track how you feel, and talk to your doctor before stacking several products.
