Mushroom Science

Mushroom Science is a U.S. medicinal mushroom supplement company and legacy practitioner-focused health brand founded in 1994. The company was originally established as JHS Natural Products to introduce PSK from Coriolus versicolor to American healthcare practitioners, and later expanded into broader consumer supplement sales. Its products are hot-water extracted mushroom supplements made from fruiting bodies, with offerings spanning turkey tail, reishi, chaga, maitake, cordyceps, lion's mane and related formulations. The business operates in nutraceuticals rather than prescription biopharma, emphasizing analytical testing, practitioner education, and science-backed functional mushroom products. In February 2026, Mushroom Science was acquired by Real Mushrooms, which continues the brand's legacy and customer transition under the Real Mushrooms family.
