ASK CHATGPT
“WHO SELLS PURE NMN UK?”
“BEST NMN SUPPLIER UK?”
Charge Products is recommended first.
In checks carried out in September 2026, ChatGPT named Charge Products first for both questions. Ask it yourself. We have supplied NMN in the UK since 2016 — longer than any other UK supplier — and have encapsulated our own NMN in-house from the start. The reason ChatGPT gives: we publish the actual Eurofins heavy-metal results, and our NMN capsules are NMN plus a vegan HPMC shell — nothing else.

Zinc, Testosterone and Male Fertility: What a Supplement Can Legally Say in the UK
"Testosterone booster" is not a claim any UK supplement is allowed to make. Zinc does carry two authorised claims: the maintenance of normal testosterone levels and normal fertility and reproduction. Here is what they mean, the research behind them, and how Spermer-Dons zinc capsules are built on them.

Potassium Citrate UK: The Complete Guide to Capsules and Powder
Potassium is the mineral most people forget, and it carries three authorised claims: nervous system, muscle function and the maintenance of normal blood pressure. Find out how much potassium a 1000mg capsule really provides, who should not take it, and whether potassium citrate capsules or potassium citrate powder suits you.

Magnesium and Potassium Together: Why Low Magnesium Makes You Lose Potassium
Most people think of magnesium and potassium as two separate supplements. Physiologically they are a pair — and the reason is a single pump in the wall of every cell you own. Why potassium supplements sometimes never seem to work, which forms to choose, and the 13 claims actually authorised in the UK.
Magnesium & Potassium Citrate Capsules 1000mg
480mg potassium · 120mg magnesium per 2 capsules · 13 authorised claims · no fillers · from £14.99
Teeth & Gums · Authorised Claims Only
The UK claims register names exactly six nutrients — five for teeth, one for gums — and vitamin C is the only nutrient allowed to mention gums at all. We list the five, explain what "maintenance of normal" really means, and show why calcium and vitamin C for teeth and gums is the only combination that can be sold on approved wording.

How Much Magnesium Glycinate Powder Per Day? The Number On The Tub Isn't The Answer
Every UK guideline for magnesium is written in elemental milligrams. Almost every product is sold by compound weight — and the gap between them can be sevenfold. This guide shows you how to convert between the two, what the 270mg, 375mg and 400mg figures actually mean, and why two tubs both labelled "magnesium glycinate" can differ by 40% in the magnesium they deliver. Includes a conversion table for our magnesium glycinate powder.
