Chaga Mushroom

No. It is cultured mycelium powder of Inonotus obliquus, not the black birch conk. Most chaga tea and most chaga research use the conk, and a 2025 analysis found grain-grown mycelium products differ sharply from it, so findings on conk don't carry over to this capsule.

No. The label says mushroom mycelium powder, 1,000 mg per serving of two capsules, standardized to 40% polysaccharides (400 mg). It does not say fruiting body, conk or extract.

The label doesn't say, and doesn't say how the polysaccharides were measured. Mycelium is usually cultured on grain, and a general polysaccharide measurement can count starch. The label prints no beta-glucan, triterpenoid or oxalate amount.

Two capsules daily, with food or on an empty stomach, or as directed by a healthcare professional.

Chaga is naturally high in oxalate. Ask a physician first if you have kidney problems or kidney stones, take blood thinners or diabetes medication, are pregnant or nursing, or under 18. Two case reports link chaga powder to kidney damage from oxalate, at about 10–15 g a day in one and an unstated long-term dose in the other; our serving is 1 g of mycelium.
