Chaga
Chaga grows on birch trunks in cold northern forests, where it spends years concentrating polyphenols and beta-glucans. Pure Filth uses the fruiting body only, dual-extracted at 15:1 so the compounds actually survive into the cup.

Cordyceps militaris is cultivated rather than wild-harvested, which is how it stays free of the adulteration that dogs wild cordyceps. It carries cordycepin and beta-glucans, the compounds behind its reputation for stamina.
Reishi has been used in East Asian traditions for centuries, valued for triterpenes and beta-glucans. It is genuinely bitter, and that bitterness is the honest signal of a real extract rather than a diluted powder.
Tremella is the "snow mushroom", long used across Asia as a beauty tonic. Its polysaccharides behave much like hyaluronic acid, holding water in the skin — which is why it has become the vegan answer to a collagen sachet.
Turkey Tail is among the most studied functional mushrooms, rich in prebiotic polysaccharides and beta-glucans. It works on the gut lining and its bacterial population rather than passing straight through.
Each pouch holds 10 g — about 5 servings. Add 2 g (about 1 level teaspoon) to hot water, coffee, tea, a smoothie or a protein shake. Work through one mushroom at a time, or stack them: Lion’s Mane and Tremella in the morning, Chaga and Cordyceps in the afternoon, Reishi and Turkey Tail in the evening.
