Supplement guides, without the hype
What each ingredient is, what UK rules allow anyone to claim about it, and how to judge a formula before you spend money on it.
How to use these guides
Quick answer
We sell a supplement, so read these knowing that. What we can offer in exchange is a consistent method: published amounts, authorised claim wording only, links to NHS and GOV.UK guidance you can check, and an honest note in every guide about where our own product is the wrong choice. That method is written down on our editorial standards page.
Where to start depends on your question. Curious about a specific ingredient? Its ingredient guide below covers what it is and what may be claimed. Comparing products? The buying guides show the method. Ready to look at ours in that light? The honest review and price page are the next stops.
| Rule | What it means in practice |
|---|---|
| Authorised claims only | Zinc and vitamin B3 claims are quoted in their permitted wording |
| Amounts always published | Every ingredient is given per daily serving, in mg |
| No invented evidence | No fabricated ratings, testimonials, customer counts or results |
| Medical questions go to a GP | Symptoms need a diagnosis, not a supplement |
| Sources you can check | NHS, GOV.UK and the GB claims register, linked at the foot of each guide |

These commitments are not marketing lines — they are the rules we are held to on the editorial standards page, including the commercial interest we state plainly at the top of each guide.

Questions about these guides
Which guide should I read first?+
If you are weighing up a specific ingredient, start with its ingredient guide. If you are deciding what to buy, start with the best testosterone support supplements guide — it shows the five-point method we use to judge any formula.
Are these guides independent, given you sell a supplement?+
We sell Vitalix Prime, and we say so at the top of every guide. What we can offer is a consistent, checkable method: published amounts, authorised claim wording only, and linked NHS and GOV.UK sources. Every guide also names the cases where our own product is the wrong choice.
Which ingredients actually carry an authorised UK claim?+
In this category, zinc (maintenance of normal testosterone levels in the blood and normal fertility) and vitamin B3 (normal energy-yielding metabolism and reduction of tiredness and fatigue). Maca, saffron, citrulline and the others may be described factually but carry no authorised claim.
Can a supplement replace seeing my GP?+
No. Persistent tiredness, low mood or changes in sexual function need a diagnosis, not a supplement. Every guide says this plainly, and the NHS sources are linked at the foot of each page.
How often are the guides updated?+
Each guide shows a last-checked date under its title. We review them when the claims register, NHS guidance or our own formula changes.
Do these guides apply outside the UK?+
They are written to Great Britain's nutrition and health claims rules. Other countries apply different rules, so treat the claims guidance as UK-specific.
Why do the guides link to the ASA and Trading Standards?+
Because those are the bodies that police misleading supplement advertising in the UK. Linking them lets you check not just our wording but anyone's.
Where do I go once I have read a guide?+
The honest review covers the full Vitalix Prime formula and our assessment method, and the price page breaks down cost per day, per month and per year. Both are linked from every guide.
