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.
