Gaia Herbs Certified Organic Lion's Mane Mushroom is grown in China, where growers have been working for 20 years to produce the highest quality organic mushrooms. They're grown in an open setting that mimics their natural environment, rather than the lab settings many mushrooms are grown in today.
With this care, no fillers, growing medium, or mycelium end up in the finished product. Our mushrooms are grown to maturity, harvested and extracted as they have been for thousands of years in Traditional Chinese Medicine.
