Shroombiosis

Functional mushrooms, made transparent

Rated 5 out of 5 from 8 reviews

Seven mushrooms for focus, calm, and gut health.

Shroombiosis is a caffeine-free powder with seven dual-extracted mushrooms, three superfoods, and clinically studied pre/pro/postbiotics, every dose printed on the label. It isn't a mushroom coffee. It mixes into whatever you already drink.

The contrast

Fifteen numbers, or one.

One blend total across six mushrooms tells you nothing about any of them. Every Shroombiosis ingredient is printed at its own amount — the seven mushrooms and the tri-biotic stack (prebiotic, probiotic, postbiotic) that none of the leading mushroom coffees carry together.

Bar length is the amount per serving — 1,000 mg is a full track. The biotic strains are measured in bacteria counts, not weight, so their rows state the context instead: each is included at the amount its human research used. Nothing is rounded, pooled, or hidden behind a blend total. Exact amounts are printed on every label.

From the founder

Why I built this

Like a lot of people, I started with the big mushroom coffees. Then I read the labels. Proprietary blends that wouldn't tell me how much of anything I was getting. Parts left unnamed. Doses I couldn't check against a single study. The claims were everywhere. The numbers weren't.

So my wife Danielle, a pharmacist, and I worked through the research ingredient by ingredient and built the thing we couldn't buy: seven mushrooms and a complete pre, pro, and postbiotic stack, every dose printed on the label where you can check it. See the label math against the big names, or read the whole story.

Don't take my word for it

Go and check us.

Ask Google. Ask ChatGPT. Pick any mushroom on our label, take the exact dose printed next to it, and see whether the research holds up. Then run the same test on whatever else you are considering — when a label gives you one number for six mushrooms, there is nothing there to check.

You will also find the places we say the evidence is thin, because we wrote those down too. That is the whole argument, and I would rather you verify it than take my word: the research behind every ingredient is published, and the label math against the big names is on one page.

Why Shroombiosis

Built on what the others leave out

Shroombiosis is a caffeine-free functional mushroom supplement: seven dual-extracted mushrooms, three superfoods, and a complete pre/pro/postbiotic stack in one daily powder, with every ingredient's dose printed on the Supplement Facts panel. It's formulated in-house by a physiologist and a pharmacist, and every batch is tested before it ships.

Transparency

The whole formula, fully dosed

Every mushroom, superfood, and biotic is listed with its amount on the label. No "proprietary blend" math hiding an underdosed ingredient.

Extraction

Dual-extracted, no grain filler

Every mushroom is dual-extracted, never mycelium grown on grain. We also name the part instead of rounding all seven to "fruiting body": Poria and Tiger's Milk are sclerotia, and we say so.

Expertise

A pharmacist and a physiologist

Formulated by Dr. Danielle Oncer (PharmD) and Onur (B.S. Physiology, Army combat veteran). The science here is reviewed and cited, not invented by a marketing team.

Not mushroom coffee

Caffeine-free, so it works with your routine, not on top of it.

Most mushroom "coffees" still hand you caffeine, along with the jitters and the afternoon crash. Shroombiosis is 100% caffeine-free, so you can stir it into your morning coffee, an afternoon tea, or just water, any time of day. The function comes from the mushrooms and biotics, not a stimulant.
