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.
The Shilajatu journal
Purity, dosage, sourcing and what the studies actually found. Every article lives at its topic address; this is the reading list.

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

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

Ashwagandha and shilajit are sold in one capsule. What each was studied for, at what dose, whether the pair has ever been tested, and who should avoid each.

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

Trials used 125 mg to 600 mg of ashwagandha a day, each tied to a named extract: KSM-66, Sensoril or Shoden. First measured change, and morning or night.

A fulvic acid percentage depends entirely on the assay behind it. We name the methods, show how far two of them overstate, and list what to ask a seller.

No shilajit trial reports an outcome before week eight. Here is what each study measured, on which day it measured it, and how to run your own trial.

Eight checks a European buyer can run on pure shilajit resin: what the label must legally carry, what a certificate of analysis covers, what home tests miss.

How much shilajit to take, when, and what to dissolve it in, with the doses the trials used. A first month, honestly, and who should not take the resin.

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 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.

Five shilajit formats compared on active load, taste, dosing and cost per gram. No trial compares absorption between forms, so here is what decides 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.

Adaptogens ranked by published trial volume, not popularity. Eight herbs and mushrooms, the largest trial for each, and where the evidence runs thin.

Fulvic acid is the water-soluble fraction of humic substances. What it is, how it is measured, why it carries minerals, and where the evidence stops.

Shilajit is a dark resin from high-altitude rock. What it is made of, how it is purified and tested, what the human trials measured, and what is unproven.

Six ways to buy shilajit in the UK, Ireland, the EU and Switzerland, compared on seller of record, batch evidence, price per gram and import cost.

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.
