Tremella has five upside articles on this site and, until now, no dedicated safety one — a gap worth closing given the species has exactly one oral human randomised trial to its name. The good news is that trial reported no adverse events. The honest caveat is that "no adverse events in 56 people over 12 weeks" i...
Chanterelle's immune-modulating mechanism — beta-glucans binding Dectin-1 and complement receptors on macrophages and neutrophils — is genuinely well characterised. It'...
Here's an uncomfortable starting point for a dosage guide: nobody has run a clinical trial establishing a safe or effective dose of Phallus impudicus in humans. The published evide...
Melatonin's own meta-analysis describes its effect as modest, and the number backs that up: 7 minutes shaved off the time it takes to fall asleep. Valerian's meta-analysis found a...
Two systematic reviews looked at chlorella and cardiovascular risk factors and reached opposite conclusions. One, pooling 19 trials and 797 subjects, found significant drops in cho...
Both get pitched at the same buyer — a man in his 40s or 50s wanting more drive and less fatigue — and both have a real trial behind that pitch. They just don't test th...
Ask what these two do and you'll get the same word twice: energy. Read the trials and neither one measured anything a tired person would recognise. Cordyceps raised the threshold a...
One of these is marketed as the brain product and the other as the stress herb. Line up the human trials on cognition in healthy adults and the labels swap places. A 2026 meta-anal...
These two get shelved together as "immune mushrooms" and their evidence could hardly be further apart. Trametes Versicolor's polysaccharide fraction has randomised survival data pu...
The usual answer is lion's mane for focus, reishi for calm, and that split is roughly right about intent and almost useless about evidence. Lion's mane has more human trials, but n...
A 2026 analysis applied a new extraction method to 63 edible mushroom samples across six species and found that every single sample contained at least one of four Alternaria toxins...
The standard warning says reishi lowers blood pressure and may therefore stack dangerously with antihypertensive medication. A Cochrane review of five randomised trials covering 39...
A 49-year-old man reached end-stage renal disease after years of daily chaga powder. When his nephrologists measured the oxalate content of what was left in his jar, it came back a...
Twenty-five published cases of ashwagandha-associated liver injury now exist across thirteen peer-reviewed papers. Most recovered fully within weeks to months of stopping. Three di...
Two studies of the same product category reached opposite conclusions, and the gap between them is the entire safety story. A Canadian survey of 18 commercial algae supplements fou...
Forty-nine habitual seaweed eaters in Norway had their iodine intake measured, then stopped eating seaweed for six weeks and were measured again. Their estimated intake fell from 6...
Two separate questions get collapsed into one here, and they have opposite answers. Does a routine workplace drug panel look for anything in a mushroom supplement? No — not a...
A mould-allergic 38-year-old went into anaphylactic shock after eating button mushrooms. The laboratory work found why: two fungal proteins, a manganese superoxide dismutase and a...
A hot-water reishi extract inhibited ADP-induced platelet aggregation more strongly than 140 µmol/L of aspirin in one laboratory screen — and left prothrombin time and...
Mushrooms really do make vitamin D when ultraviolet light hits them, and the food-science story usually stops there. The clinical story does not. In a 2026 randomised trial, adults...
Adaptogen and nootropic are not vague wellness adjectives. Both were coined by named scientists who published explicit criteria — three conditions for an adaptogen in 1969, f...
A 10:1 extract ratio is a statement about weight, not about strength. It says ten kilograms of mushroom went in and one kilogram came out — a 10% yield. It says nothing about...
"Dual extracted" is printed on more mushroom products every year and defined by nobody. There is no standard behind it, no minimum ratio, no required disclosure of either solvent....
Human cells carry a transporter, OCTN1, whose main known job is to pull one specific molecule out of the bloodstream and concentrate it inside tissue. We cannot synthesise that mol...
Every published human shilajit trial used between 200 and 500 mg a day for 90 days. The only trial that compared two doses head-to-head found 250 mg a day was indistinguishable fro...
Shiitake has one genuine, well-documented adverse effect, and it's caused by the exact compound shiitake is sold for. Lentinan — the beta-glucan behind every immune claim on...
Cortisol is the number this whole category is sold on, and it's the number you should trust least. Two systematic reviews published within a year of each other, pooling largely the...
There is no standard propolis dose, and the reason is structural: propolis composition depends on which plants the bees visited, so a gram from Brazil and a gram from Poland are di...
Search any mushroom and a medication together and you'll find a warning. Search for the case report behind it and you usually won't. Across the entire functional mushroom category,...
Every serious brand in this category tells you to ask for a certificate of analysis. Almost none of them tell you what to do with it once you're holding one. So people open a PDF,...
