PURE FILTH began with the founder's personal search for sharper focus, which led to Lion's Mane and set off a two-year hunt for the most potent mushrooms available. That standard shapes every product: only the fruiting body, the part of the mushroom richest in bioactive compounds, made into high-potency extracts. Dual extraction unlocks the full spectrum of actives, and every product is third-party tested. Across a range covering focus, calm, energy, immunity, gut health and beauty, PURE FILTH is on a mission to make functional mushrooms effortless, approachable and part of everyday wellness.
