Monterey Nutraceuticals is the current medicinal mushroom industry split between low-quality producers and US cultivators with limited capabilities and product offerings. The industry is void of a low-cost, US-based producer that can offer a full medicinal mushroom product line (pure fruiting body and mycelium-based products) and that can serve as an unbiased, scientifically sound market educator and leader. As the industry leader for over 50 years, Monterey Mushrooms has the production capacity, expertise, distribution network, R & D capability, and trusted brand to fill the market void and become the dominant global supplier of US-grown medicinal mushrooms. We know mushrooms! From seed (spawn) to powder, we have control over every aspect of our business as we're a vertically integrated mushroom producer in North America. The spawn we use to grow our medicinal mushrooms is produced by our affiliate, Amycel SpawnMate. Then, we grow, dry, and package everything at our facilities in California to ensure our mushroom powders reach their full potential. If that is not enough, we third-party test for heavy metals, pesticides, mycotoxins, polysaccharides, and various compounds. In house, we test every product for potency, quality, and purity, and we have that verified by a third party periodically. Monterey Nutraceuticals is a portfolio company of Paine Schwarz Partners, who invested in the business in May 2022. For more information, visit us www.montereymushrooms.com/nutraceuticals.
