Male Vitality: What Science Really Says
Type "natural testosterone supplement" into a search engine, and you'll find dozens of products promising dramatic increases, "x3," "immediate boost." That's precisely the problem: the vast majority of these promises have no solid regulatory or scientific basis, and the subject deserves a more honest treatment.
In this article, we distinguish between what is truly validated by the European Food Safety Authority (EFSA), what falls under traditional use without consensual proof, and what is pure marketing.
This article is for informational purposes only and does not replace medical advice. A persistent decrease in libido, sexual fatigue, or a drop in vitality can have causes beyond nutrition (diabetes, cardiovascular disorders, hormonal disorders, medication side effects, stress, or depression): medical advice allows these causes to be ruled out first.
What "male vitality" means
The term is deliberately vague in marketing and actually covers several different things: general energy levels, libido, erectile function, and testosterone levels. These are four related but distinct topics, which do not have the same causes or the same solutions.
What is actually authorized by European regulations
Zinc
It is the only active ingredient in this category to benefit from officially authorized health claims by EFSA (EU Regulation No 432/2012): zinc "contributes to the maintenance of normal testosterone levels in the blood" and "contributes to normal fertility and reproduction."
An important point, often overlooked by marketing: these claims refer to the maintenance of a normal level, not an increase beyond normal. Specifically, zinc helps correct an actual deficiency (common in cases of unbalanced diet or intense sports training), but it does not raise testosterone in a man whose intake is already sufficient. The maximum daily dose authorized in food supplements in France is 15 mg.
What falls under traditional use, without consensual proof
Tribulus terrestris
Very present in so-called "performance" supplements, tribulus does not benefit from any EFSA-authorized health claim regarding testosterone or libido. Available studies are limited, small in size, and their results are contradictory depending on the protocols used.
Maca
Already discussed in our article on lack of energy. It is important to specify here that maca does not directly affect sex hormone levels (testosterone or estrogen) according to currently available data — it is traditionally used for general vitality rather than for a targeted hormonal effect.
A substance still little known in France: shilajit
Shilajit is sometimes associated with male vitality in some marketing content, particularly in connection with its richness in trace elements (including zinc, in its natural state and in varying quantities depending on the batches).
It is important to be clear: shilajit does not benefit from any EU-authorized health claim regarding testosterone, libido, or sexual function. The few existing studies on the subject are small and, as yet, do not allow for a conclusion validated by scientific consensus. Its use is based on ancient tradition, not on demonstrated effectiveness in this specific area.

How to spot misleading marketing
Some warning signs that should alert you, on any site (including ours — feel free to challenge us if you see wording that seems excessive):
- Precise figures without sources ("+300% testosterone")
- Absence of mention of actually authorized EFSA claims
- Customer testimonials presented as scientific evidence
- Absence of any warning or usage limit
FAQ
Does zinc really increase testosterone? It helps correct a deficiency if one exists, which can indeed restore a normal level. In a man who is not deficient, additional zinc intake has not shown any additional effect on testosterone.
Does shilajit increase testosterone? To date, there is no EFSA-recognized health claim on this subject, nor a solid scientific consensus. The available data are too limited to affirm it.
When should you consult a doctor rather than try a supplement? If a decrease in vitality, libido, or sexual fatigue is new, marked, or accompanied by other symptoms (weight gain or loss, mood disorders, shortness of breath), medical advice is recommended first and foremost to rule out a treatable cause.
In summary
On the subject of male vitality, very little is actually validated by European regulations — zinc, in case of a real deficiency, is the best-established case. The rest (tribulus, maca, shilajit) falls under traditional use that deserves to be presented as such, without promise of guaranteed effect.
