We extract the most promising compounds from organic mushrooms and plants, so you get the best of natural support. Because your body needs what works.

Reishi Extract. Traditionally known as the “mushroom of immortality,” Reishi is rich in triterpenes and β-glucans, studied for their role in supporting immune balance, stress recovery, and internal resilience. Our triple-extracted Reishi delivers these bioactives in a liquid, bioavailable form, ideal for those seeking calm, steady energy, and daily support for physiological balance.

Lion’s Mane Extract. Known for its unique ability to support the nervous system, Lion’s Mane contains hericenones and erinacines, compounds studied for their influence on neurogenesis and cognitive clarity. Our triple-extracted formula delivers these compounds in a bioavailable liquid form, ideal for adults seeking sharper focus, long-term cognitive support, and brain-friendly daily supplementation.

Chaga Extract. Often referred to as one of the most antioxidant-rich superfoods, Chaga contains polyphenols, melanin, and β-glucans, compounds studied for their roles in immune support and oxidative stress defense. Our triple-extracted liquid form ensures high bioavailability, offering a convenient way to support your body’s natural defenses, cellular balance, and long-term vitality.

TriExtract. A triple-extracted blend of Chaga, Reishi, and Lion’s Mane, three of the most studied functional mushrooms. This all in one liquid formula combines their complementary active compounds to support daily vitality. Designed for optimal bioavailability, it offers a well-rounded approach to immune balance, cognitive clarity, and natural oxidative stress protection.
