Ashwagandha and Body Weight, Trial by Trial
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.

Herbs
The herbs section is mostly ashwagandha, because ashwagandha is where the evidence is: a dozen randomised trials, mostly of eight to ten weeks in groups of about sixty, measuring perceived stress, anxiety scales, sleep and cortisol. It is also where the regulatory movement is. The German BfR advised in 2024 that children, pregnant and breastfeeding women and anyone with a liver history should not take it, and Denmark has restricted it. Both facts belong on the same page, and here they are.
Ashwagandha benefits and side effects is the pillar, with the position country by country. Dosage and timing ties every milligram figure to a named extract. Ashwagandha and cortisol reads the hormone data on its own, and ashwagandha and body weight answers the question that is asked in every language. Spirulina is filed here too, as an alga rather than an adaptogen, with its own trial literature.
Ashwagandha, Cortisol, Sleep and Anxiety, Trial by Trial
Every ashwagandha cortisol trial with its dose, duration, population, the exact cortisol measurement behind it and who funded it, plus the sleep data.
Ashwagandha and Shilajit, Compared on What Was Measured
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.
Ashwagandha Benefits and Side Effects, Trial by Trial
What ashwagandha trials actually measured, the liver case reports behind the European restrictions, and the country by country legal position with dates.
Ashwagandha Dosage, Onset and Timing, Read Off the Trials
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.
Spirulina, Audited: The Trials, the Protein and the B12
Every human spirulina trial with its dose, size and duration, plus the protein arithmetic per capsule, the pseudovitamin B12 problem and microcystins.
What Are Adaptogens? Eight Ranked by Strength of Evidence
Adaptogens ranked by published trial volume, not popularity. Eight herbs and mushrooms, the largest trial for each, and where the evidence runs thin.

Adaptogens
The herbs and mushrooms paired with the resin in the capsule range. Ashwagandha, Lion’s Mane, Reishi, and what each one is actually for.
The questions everyone asks
What is shilajit, actually?
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.
Why does fulvic acid matter?
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.
How much do I take, and when would I notice anything?
Follow the instructions and maximum daily amount on the label of the specific product. Resin, liquid and capsule formulas are not interchangeable doses. We cannot promise a noticeable effect or a time to benefit. If you take medicines or have a medical condition, discuss the product with a qualified healthcare professional before use.
Resin or capsules?
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.
Where does it come from, and how do I know it is clean?
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 63849 from Alex Stewart Agriculture concerns a resin sample tested in February 2026. It does not establish results for every current retail batch or any capsule formula. Current batch mapping remains unverified; the arsenic result needs clarification against the printed detection limit.
Do you ship outside Europe?
We ship worldwide, with one exception: not to the United States. Switzerland pays CHF 6.90, free from CHF 60, shipped from Winterthur by Swiss Post with no customs. Europe and the United Kingdom pay CHF 6.90, free from CHF 150. Every other country pays CHF 14.90, free from CHF 200, without a localised site.
