What this section is for
What the published work measured, in how many people, for how long, and what it did not show. Every number here is attached to a citation you can open, and the ones that are not strong enough to state are left out.

No ashwagandha trial has ever recorded weight gain as a side effect. Here is every trial that measured body weight, its size, population and sponsor.

Every ashwagandha cortisol trial with its dose, duration, population, the exact cortisol measurement behind it and who funded it, plus the sleep data.

What ashwagandha trials actually measured, the liver case reports behind the European restrictions, and the country by country legal position with dates.

Raw shilajit can carry lead, arsenic, mercury and cadmium. The EU limits for supplements, one real certificate held against them, and how to read a report.

Every human lion's mane trial with its size, dose, duration and population, the three that found nothing, and why fruiting body or mycelium changes the jar.

Every human Ganoderma lucidum trial with its dose, duration and population. What reishi was measured to change, what it was not, and who should avoid it.

Every human shilajit trial, with its dose, duration, population and the extract it used. What was measured, what was never measured, and who should avoid it.

Two randomised trials have tested shilajit in men. The dose, the duration, who paid for them, and the four things neither of them ever measured.

Two published trials have enrolled women: skin gene expression in 45, bone density in 60. What each measured, the iron question, and who should not take it.

What shilajit side effects the published trials recorded, the six groups who should not take it, what not to combine it with, and what nobody has tested.

Every human spirulina trial with its dose, size and duration, plus the protein arithmetic per capsule, the pseudovitamin B12 problem and microcystins.

Guides, science, sourcing, comparisons and protocols. The same subject approached from five directions, and the reading list holds all of it in one place.
A dark resin that seeps out of rock at altitude in the Himalaya, made of plant matter pressed and broken down over a very long time. What comes off the rock is not the product. Shodhana, the purification step, is what separates the resin from everything it was sitting in, and that is the step worth asking a seller about.
Fulvic acid is a carrier molecule. It binds trace minerals and is studied as a way of getting them across a cell membrane, which is why the interesting question about a mineral is not how much is in the jar but how much of it arrives. That is the mechanism the research is built on. It is a line of study, not a settled fact, and nobody should sell it to you as one.
A rice-grain portion, dissolved in warm water or under the tongue, once a day. A 30g jar lasts two to three months at that dose. Shilajit is not a stimulant and nothing here works like one, so the honest unit of time is a month rather than an afternoon. If you want the caffeine experience this will disappoint you.
The range includes resin and six distinct capsule formulas in vegan HPMC shells. Ingredient amounts are listed for each product rather than reduced to one formula for the whole range. One caution: the Sea Moss and Bladderwrack blend contains iodine, so if you have Hashimoto’s or any diagnosed thyroid condition, take that one to your doctor rather than to the checkout.
Our products come from the white-label range offered by established UK supplier Pure Shilajit UK. The supplier describes its resin as Himalayan-sourced. Certificate of Analysis 63849 from Alex Stewart Agriculture, Liverpool (ISO 17025 accredited analyses) covers the February 2026 resin batch: arsenic 0.02, cadmium under 0.2, lead 0.44 and mercury 0.03 mg/kg. It covers the resin only; the capsules are not independently tested.
