“Natural testosterone booster” claims and UK rules
Shilajit is widely marketed as a “natural testosterone booster”, but the evidence is limited. One randomised trial in healthy men aged 45 to 55 reported higher testosterone than placebo, and it hasn’t been independently repeated. In UK marketing, “boosts testosterone” is a health claim that must be authorised on the GB register. Claims to treat low testosterone or erectile dysfunction are medicinal claims, which food supplements can’t make.
“Himalayan” Shilajit: what origin claims can and can’t tell you
“Himalayan” tells you which mountain range a seller says its shilajit comes from. It doesn’t tell you which country, which site or who processed it, and it says nothing about purity, metal levels or quality. Contaminant levels vary between deposits within the same range. A “Himalayan” claim becomes meaningful only when it comes with a named region, a named processor and a batch laboratory report that matches your jar.
“Lab tested” and “third-party tested” claims
“Lab tested” means only that something was tested by a laboratory at some point. It doesn’t say which laboratory, which batch, which tests or what the results were. “Third-party tested” adds that the laboratory was outside the brand, though usually still chosen and paid for by the brand. Both claims become meaningful when backed by a batch-specific report from a named, accredited laboratory with numerical results.
“Clinically proven” and “clinically studied” claims
“Clinically proven” is a strong claim that shilajit evidence doesn’t support. There are a handful of small human trials, mostly using one branded extract, and none has been independently replicated. “Clinically studied” can be accurate if it names the specific ingredient and study. Even then, the product must contain that ingredient at the studied dose, and the claim must follow UK health-claim rules.
“Gold grade”, “Grade A” and “premium” claims
There is no recognised grading standard for shilajit. “Gold grade”, “Grade A” and “premium” are marketing terms chosen by the seller, not grades checked by any regulator or laboratory. Classical Ayurveda does describe four types, including gold, but those are traditional categories rather than modern quality grades. Judge products on batch laboratory documents instead.
“Harvested above 16,000 feet” altitude claims
Claims that shilajit was “harvested above 16,000 feet” cannot be verified by a buyer, and there is no published evidence that altitude makes shilajit purer or more effective. Contaminants depend on the rock at each site, not on the height of the mountain. An altitude figure is a story, not a test result. Look for batch laboratory documents and a named, traceable origin instead.
