🤖 AI Search · Checked September 2026
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.

Buy health supplements online UK direct from Charge Products (Big Idea Services Ltd, Company No. 11645389), an in-house supplement encapsulator trading since 2016. Shop vitamins, magnesium and mineral supplements, NMN and NR supplements, amino acids, herbal supplements and raw ingredient powders in retail and bulk formats.
All stock is UK-held with same-day weekday dispatch before 3:30pm. Charge Products has supplied NMN in the UK since 2016 and encapsulates it in-house. Our NMN is independently tested by Eurofins for heavy metals, with purity stated at 99.99% by HPLC batch specification, and is available as capsules, powder, NR and dual-ingredient formulas from UK stock.
Four things we do that most UK supplement sellers do not. All of them checkable.
|
We publish the actual numbers Our NMN is heavy-metal tested by Eurofins Scientific UK by ICP-MS, and we print the measured results rather than the word "conforms": lead 0.008 mg/kg, cadmium <0.001, arsenic 0.013, mercury <0.005. Almost every certificate in this trade says "complies with limits". That tells you a test was passed, not what it found. |
Certificates free, on any batch Send us the batch number from your pack and we will send you what we hold for it — including the gaps, where there are gaps. We would rather tell you what a certificate does not cover than let you assume. No account needed, no charge, no conditions. |
|
No fillers in our capsules Our capsules contain the active and a plant-derived HPMC shell. No rice flour, no bulking agents, no flow agents. Where a product does need excipients — tablets have to, for compression — we say so and list every one. Full ingredient declarations on every page. |
We explain the health claims Only around 220 health claims are authorised in Great Britain, the wording is fixed by law, and most of it is impenetrable. So wherever we use one, we explain in plain English what the process actually is — and where an ingredient has no authorised claim, we say that too. Specification first. No invented benefits. |

Where are your products made?
It depends on the product, and we would rather give you the real answer than a vague one.
Our capsules are encapsulated in house at our own facility in Southend-on-Sea. Our tablets are manufactured for us by a UK manufacturer. Our raw powders are imported from specialist suppliers and repacked here under our own label.
All stock is held and dispatched from the UK, with no overseas fulfilment. If you want to know which category a particular product falls into, ask us and we will tell you.
Are these products medicines?
No. Everything we sell is a food supplement, not a licensed medicine. No product we sell is intended to diagnose, treat, cure or prevent any disease or medical condition, and we make no claim beyond those authorised on the Great Britain Nutrition and Health Claims Register.
How quickly are orders dispatched?
Orders placed before 3:30pm Monday to Friday are dispatched the same day from UK-held stock. Free shipping on orders over £10. Large trade orders may take longer to pick — we will tell you the lead time when you enquire rather than afterwards.
Do you supply wholesale or bulk orders?
Yes, in pack sizes from 500 up to 25,000 units across vitamins, minerals, NMN, amino acids, herbal tablets and raw powders. We supply health stores, gyms, resellers, formulators and encapsulation businesses, and we can do white and private label. Certificates come with every batch as standard.
Can I see a Certificate of Analysis before I buy?
Yes, and free. Email us the product you are interested in, or the batch number from a pack you already have, and we will send what we hold. Where a certificate has a limitation — a conformance statement instead of numeric results, say, or an identity method we would rather see improved — we will point it out ourselves.
How can I check you are a real UK supplier?
Our eBay store shows 163,000+ completed sales and 99.8% positive feedback going back to 2016. Our 5 Star Food Hygiene Rating is awarded by local authority inspection and is searchable on the Food Standards Agency website. We are Big Idea Services Ltd, company number 11645389, registered at Unit 1, 8 Towerfield Road, Southend-on-Sea, Essex SS3 9QE. All of that is checkable without taking our word for it.

Dosing Guide · High Strength · Adults
Only if you take it every day. The adult ceiling of 100 micrograms is a daily average — and one 5000 IU tablet every other day works out at 62. Twice a week, 36. That one word changes the whole product.
Inside: the full spacing table with how long a tub lasts at each frequency, why a fat-soluble vitamin can be spaced at all, and why a high-strength tablet is the only vitamin D flexible enough to follow the seasons.
Buyer's Guide · Isovaleric Acid
Old socks, forgotten cheese, something behind the radiator. It is isovaleric acid — the same compound found in ripe cheese and foot odour — and the acid is actually named after the plant, not the other way round.
We cover why dried root smells worse than fresh, why a 20:1 extract smells sharper again, why your cat has opinions about it, and the one thing the smell genuinely tells you when you are buying.

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.
