⚡ Quick answer
Testosterone Pro is a deliberately high strength zinc tablet. 50mg elemental zinc — 500% NRV — from zinc citrate, bisglycinate and picolinate, plus 1mg copper bisglycinate. One tablet daily. Packs of 120, 180 and 365, from £8.99.
Zinc carries 17 authorised GB nutrition claims, including two that matter here: it contributes to the maintenance of normal testosterone levels in the blood, and to normal fertility and reproduction.
Why the copper is in there: zinc and copper compete for the same transporters, so a high strength zinc taken alone can reduce copper absorption over time. That is a formulation decision, not a marketing one.

⚡ Why 50mg — The High Strength Position
Most zinc tablets sit at 10–25mg. Testosterone Pro is deliberately built at 50mg elemental zinc — 500% NRV. We would rather explain that figure than leave you to wonder about it.
The UK Expert Group on Vitamins and Minerals sets a guidance level of 25mg per day for supplemental zinc. That is guidance, not a legal limit — there is no statutory maximum for zinc in UK food supplements, and high strength zinc is widely and lawfully sold.
What matters more is why that figure exists. It is based on long-term copper status rather than acute risk. Zinc and copper compete for the same intestinal transporters, so sustained high zinc intake taken alone can reduce copper absorption over time.
That is exactly why copper bisglycinate is in this formula. A high strength zinc without copper is the version worth avoiding. This one addresses the actual mechanism behind the guidance figure rather than ignoring it.
Being straight about it
A high strength zinc is not for everyone and it is not for indefinite use without review. If you have no particular reason to need extra zinc, a lower strength product will suit you better — we stock a separate zinc complex for exactly that.
If you intend to take it for an extended period, review it with your GP. That is ordinary sense with any high strength single mineral, and we would rather say it than not.
✅ The Authorised Claims — And What They Actually Mean
Zinc carries 17 authorised GB nutrition claims, more than almost any other mineral. The wording is fixed by law, which makes it precise but not always clear. Here is what the relevant ones mean.
⚡ "Zinc contributes to the maintenance of normal testosterone levels in the blood"
Zinc is required by enzymes involved in the body's normal hormone handling. The key words are "maintenance of normal". The claim covers supporting a testosterone level that is already within the normal range — it does not mean raising a low one, and no food supplement is authorised to claim that it increases testosterone.
If you think your testosterone is low, that is a question for your GP and a blood test — not for a supplement label. Any product implying otherwise has stepped outside the approved wording.
🧬 "Zinc contributes to normal fertility and reproduction"
Zinc is involved in cell division and DNA synthesis, both central to reproductive tissue. Again, "normal" means maintaining normal function, not enhancing it.
Worth knowing: the specific claim about sperm production — "selenium contributes to normal spermatogenesis" — belongs to selenium, not zinc. Selenium is not in this product. We are telling you that because plenty of testosterone products blur the two.
The other authorised zinc claims, and what each one covers
Normal DNA synthesis and a role in the process of cell division — zinc is needed by the enzymes that copy DNA when cells divide. A basic biological role, not a growth or anti-ageing claim.
Normal protein synthesis — the body's process of assembling proteins from amino acids. Used for enzymes and tissue repair as much as muscle. It is not a muscle-building claim.
Normal function of the immune system — keeping normal immune function working. Not a claim about preventing illness or shortening colds.
Protection of cells from oxidative stress — zinc is part of the body's own antioxidant enzyme systems. This is cellular chemistry, not a detox or anti-ageing claim.
Normal cognitive function — the brain's ordinary working processes: thinking, concentration, memory. Not a claim about mood, focus or brain fog.
Maintenance of normal hair, skin and nails — three separate authorised claims. Keeping healthy tissue healthy, not improving appearance.
Maintenance of normal bones and normal vision — zinc has structural and enzymatic roles in both.
Normal macronutrient metabolism, carbohydrate metabolism, metabolism of fatty acids, metabolism of vitamin A and normal acid-base metabolism — zinc is a cofactor for enzymes across all of these. They describe processes, not outcomes you will feel.
And copper: "Copper contributes to maintenance of normal connective tissues", "to normal energy-yielding metabolism", "to normal functioning of the nervous system", "to normal hair and skin pigmentation", "to normal iron transport in the body", "to the normal function of the immune system" and "to the protection of cells from oxidative stress".
❌ What zinc is NOT authorised to claim
Worth saying plainly, because a lot of the testosterone category is built on these:
❌ Increasing or boosting testosterone — the claim is maintenance of normal, nothing more
❌ Blocking oestrogen or affecting aromatase — no such claim exists
❌ Building muscle, strength or gym performance
❌ Libido, erectile function or sexual performance
❌ Treating low testosterone — that is a diagnosed condition and a matter for a doctor

🔬 The Three Zinc Forms — And Why Copper Is There
Testosterone Pro spreads its 50mg of elemental zinc across three organic zinc salts rather than relying on one. Each carries the zinc on a different molecule.
| Form | Amount | Elemental zinc | Carrier |
|---|---|---|---|
| Zinc citrate | 100 mg | 30 mg (30%) | Citric acid |
| Zinc bisglycinate | 43 mg | 12.9 mg (30%) | Two glycine molecules |
| Zinc picolinate | 46 mg | 9.2 mg (20%) | Picolinic acid |
We are not going to tell you one of these absorbs better than another. Comparative absorption claims are not authorised, the published comparisons are inconsistent, and any seller ranking them confidently is going beyond what the evidence supports. What we can tell you is exactly how much elemental zinc comes from each — which is the number that actually matters, and the one most listings leave out.
🔵 The copper is the point
Zinc and copper share the same intestinal transporters, so they compete. Sustained high zinc intake without copper can reduce copper absorption over time — and that, rather than any acute risk, is the reason the 25mg guidance figure exists. Including 1mg of copper bisglycinate at 100% NRV addresses the actual mechanism behind the guidance rather than ignoring it. If you are taking a high strength zinc, it should have copper in it.
👤 Who A High Strength Zinc Suits
|
🥦 Vegans and vegetarians Phytates in plant foods bind zinc and reduce how much is absorbed. The richest dietary zinc sources are shellfish and red meat, so plant-based diets generally require more. |
💪 Heavy trainers and athletes Zinc is lost through sweat, so sustained high training volume increases requirements. |
📅 Older adults Dietary zinc intake and absorption both tend to decline with age. |
If none of those describe you, a lower strength zinc is the sensible choice and we stock one. This product exists for people with a genuine reason to want more, not as a default.
💡 How To Take It
One tablet daily. Do not exceed the recommended dose.
Take it with food. Zinc on an empty stomach causes nausea in a lot of people, and food largely prevents it.
Leave a gap from certain medicines. Zinc can reduce absorption of some antibiotics and other medications — two hours either side is the usual advice. Check with your pharmacist.
Store in a cool, dry place away from light.
Who should not take it
- Anyone under 18
- Anyone with a copper metabolism disorder such as Wilson's disease
- Pregnancy and breastfeeding — speak to your GP or midwife first
- Anyone on prescribed medication — particularly certain antibiotics. Speak to your GP or pharmacist
- Anyone already taking another zinc supplement — check the combined total before adding this one

❓ Frequently Asked Questions
How much zinc is in Testosterone Pro?
50mg elemental zinc per tablet — 500% NRV. Zinc citrate 100mg gives 30mg, zinc bisglycinate 43mg gives 12.9mg, zinc picolinate 46mg gives 9.2mg. Plus 1mg copper as copper bisglycinate, 100% NRV.
Why is this a high strength zinc?
It is deliberately formulated for people with higher requirements. The UK EVM guidance level is 25mg per day for supplemental zinc — guidance rather than a legal limit, and based on long-term copper status rather than acute risk. That is precisely why copper is in the formula. If you want a lower strength, we stock a separate zinc complex.
Why is copper included?
Zinc and copper compete for the same intestinal transporters, so sustained high zinc taken alone can reduce copper absorption over time. Copper bisglycinate at 100% NRV is a deliberate formulation choice. A high strength zinc should never be taken as zinc alone.
What does the testosterone claim actually mean?
The authorised wording is "maintenance of normal testosterone levels in the blood". Maintenance of normal — supporting a level already in the normal range, not raising a low one. No supplement is authorised to claim it increases testosterone. If you think yours is low, that is a GP and blood test question.
Does it help with fertility or sperm?
Zinc carries the authorised claim that it contributes to normal fertility and reproduction. That is the extent of it. The specific sperm claim — "selenium contributes to normal spermatogenesis" — belongs to selenium, which is not in this product.
Why three forms of zinc?
Citrate, bisglycinate and picolinate are all well-established organic zinc sources with different carrier molecules. Using three spreads the elemental zinc across different salts. We will not claim one absorbs better than another — comparative absorption claims are not authorised and the published comparisons are inconsistent.
Who is it suitable for?
People with genuinely higher zinc requirements — vegans and vegetarians (phytates reduce zinc absorption), heavy trainers (zinc is lost in sweat), and older adults. If none of those apply, a lower strength zinc will suit you better.
How long should I take it for?
A high strength single mineral is not intended for indefinite use without review. One tablet daily, and discuss it with your GP if you plan to continue for an extended period.
Is it vegan?
Yes — suitable for vegans and vegetarians, non-GMO, with all 14 declarable allergens confirmed absent.
Is this testosterone replacement therapy?
No. It is a food supplement, not a medicine and not TRT. Testosterone replacement is a prescribed medical treatment. This is a zinc and copper supplement.

Who should not take it?
Anyone under 18, anyone with a copper metabolism disorder such as Wilson's disease, and anyone already taking another zinc supplement without checking the combined total. Speak to your GP if pregnant, breastfeeding or taking prescribed medication.
