Purified shilajit linked to higher testosterone in healthy men in 90-day trial

A randomized, placebo-controlled trial in healthy men ages 45 to 55 found purified shilajit was associated with about a 20% rise in total testosterone over 90 days. The result is drawing attention because it points to a specific standardized formulation, while also underscoring the need for larger studies and careful sourcing.

Why it matters: - The trial adds a controlled data point to a category often driven by marketing and tradition rather than human clinical evidence. - The findings matter most for men comparing ingredient claims with actual research, since the study tested a standardized, purified form rather than raw shilajit. - The research also reinforces a basic safety issue: sourcing and purification can determine whether a shilajit product is comparable to the one studied.

What happened: - A randomized, double-blind, placebo-controlled trial published in Andrologia in 2016 tested purified shilajit in 75 healthy men ages 45 to 55. - Participants took 250 milligrams twice daily for 90 consecutive days. - Total testosterone rose about 20% versus placebo over 90 days. - Free testosterone rose about 19% versus placebo over the same period. - The authors called the finding preliminary and asked for larger, longer studies.

The details: - The trial evaluated one standardized, purified shilajit formulation, so the results do not automatically apply to other shilajit products. - The ingredient tested was checked for heavy metals, which matters because raw or unrefined shilajit can vary in composition and may carry contaminants. - The study focused on healthy men, not on treatment for a medical condition. - The research describes a hormone change, not a proven clinical outcome for energy, strength, fertility or other health claims. - UltimaPeak, a wellness brand based in Dover, Delaware, included the study in its ingredient-transparency materials for readers who want the full evidence trail. - The brand’s shilajit-based line is also discussed in UltimaPeak Shilajit Complex Reviews. - UltimaPeak’s product lineup also includes pumpkin seed oil, Irish sea moss, a beef organs complex, beetroot and magnesium options.

Between the lines: - The study gives shilajit supporters a measurable result, but it also narrows the claim to one dose, one formulation and one group of men. - The emphasis on purification is important because “shilajit” alone does not tell buyers whether a product matches the clinical trial material. - The company’s messaging leans on transparency and evidence review, which is a signal that consumers in this category are asking for documentation, not just labels. - A spokesperson said many men researching the category are trying to separate real evidence from marketing, and that the science on purified shilajit is worth reading in full.

What's next: - Researchers will need larger and longer trials before anyone can say whether purified shilajit reliably raises testosterone across broader populations. - Future studies would also need to test whether different sourcing, purification methods or dosages change the outcome. - Men considering a supplement change should talk with a doctor first, especially if they have a health condition or take medication. - The current evidence supports curiosity, not a broad health promise.

The bottom line: - Purified shilajit showed a testosterone boost in one small human trial, but the finding is narrow, formulation-specific and not ready to stand in for broader clinical proof.
