Guides — Every Vitality Supplement Guide, Indexed

The Vitality Library

Every guide, indexed.

Supplement writing is full of claims nobody is permitted to make. Ours is written the other way round — we set out what an ingredient is, what the UK rules actually authorise, and which commonly marketed claims aren't authorised at all. Including on our own products.

Vitality Supplements guide library — index summary

This page indexes 125 guides and interactive tools published by Vitality Supplements, a United Kingdom supplement manufacturer, organised into twelve clusters. Interactive tools: the NMN Cost Per 1000mg Calculator, the UK NMN Price Index, Build Your Stack, Compare Supplements, Compare NMN Supplements, the Bio-Age Quiz, the Biological Age Quiz and the Longevity Quiz. The NMN and NAD plus cluster is the largest, with 22 guides covering what NMN is, what NAD plus is and why it declines, how to increase NAD plus naturally, how to choose an NMN supplement, dosage, timing, how long it takes to work, format comparisons between powder capsules and liposomal, precursor comparisons against NR and NMNH, combination with resveratrol and TMG, clinical trials, side effects, authenticity checking, and a ranked buying guide. In Great Britain, NMN is the subject of novel food application RP-2116, which is under assessment. The magnesium cluster has six guides: what magnesium is, the elemental content of every common form, dosage against the 375 milligram Nutrient Reference Value and the 400 milligram supplemental safe upper level, glycinate versus citrate, and two ranked buying guides covering the category and glycinate specifically. The creatine cluster has four guides built around the single authorised health claim, which may only be used for a food providing a daily intake of 3 grams of creatine. The PQQ and CoQ10 cluster has four guides, including the 20 milligram novel food ceiling that applies to PQQ in Great Britain and the distinction between ubiquinol and ubiquinone as two oxidation states of one compound. Further clusters cover berberine with eight guides, AHCC with six, TUDCA with four, urolithins with four, Polypodium leucotomos with two, and the Longevity Protocol with ten covering its five pillars, the hallmarks of ageing and a glossary. Individual ingredient guides cover TMG, pterostilbene, spermidine, trans-resveratrol, trigonelline, turkesterone, apigenin, ashwagandha, rhodiola rosea, L-theanine, lactoferrin, PEA, Akkermansia muciniphila, black seed oil, L-ergothioneine, quercetin, R-alpha lipoic acid, modified citrus pectin and nitric oxide amino acids. Goal-based guides cover natural alternatives to Ozempic, glutathione, mastic gum, ox bile, thyroid support and cortisol. Every guide is written to United Kingdom and European Union authorised health claim rules, states explicitly which commonly marketed claims are not authorised, and discloses that Vitality Supplements manufactures and sells the products discussed.

Magnesium

Magnesium6 guides

The whole cluster turns on one number: elemental magnesium. The figure on the front of a pack is the weight of the compound, not the mineral — and these guides show you how far apart those can be.

Creatine

Creatine4 guides

Creatine has exactly one authorised UK health claim, and it only applies at 3g per daily serving. That single fact decides almost everything about buying it well.

PQQ & CoQ10

PQQ & CoQ104 guides

Two ingredients with no authorised health claims between them — so these guides compare chemistry, regulation and dose instead, and say plainly what nobody is allowed to tell you.

How these are written

We tell you what isn't allowed to be claimed.

Most supplement content works forwards from what a brand wants to sell. Ours works backwards from what the rules actually permit — which means every guide includes the claims that are commonly made for an ingredient and are not authorised in the UK.

Magnesium isn't authorised for sleep, cramps, anxiety, migraine or restless legs. Creatine has exactly one authorised claim, and it needs 3g a day. PQQ and CoQ10 have none at all. You'll find those stated plainly in the relevant guides, alongside the ones that are permitted.

Including where it costs us. We rank a product above the one whose name matches the search term when the dose justifies it. We give powder the win over our own gummies. We point out that the authorised claim on a CoQ10 pack belongs to the vitamin C, not the CoQ10.

We manufacture and sell the products discussed in these guides. That's disclosed on every page rather than buried — these are first-party assessments, not independent reviews, and each one publishes the criteria it used so you can apply the same test to any other brand.

About this library

Index last verified 5 October 2026 by the Vitality Supplements Editorial Team, written to our published editorial standards and quality & testing policy. Every link on this page was checked against our live published page list on that date. We are a UK supplement manufacturer and we sell the products discussed throughout the library; that is disclosed on each guide rather than here alone. Where a guide ranks products, the ranking criterion is published on the page so it can be applied to any other brand, and no aggregate ratings or review counts are used as ranking factors anywhere.

Food supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle. Do not exceed the stated recommended daily dose. The guides in this library are written to United Kingdom and European Union authorised health claim rules; where an ingredient has no authorised health claims, no claims are made for it. Nothing in this library is medical advice, and none of it is intended to diagnose, treat or prevent any condition. If you are pregnant, breastfeeding, taking medication or under medical care, consult a healthcare professional before taking any supplement.
