The booming business of functional mushroom supplements is showing no signs of slowing. First labeled as “just the latest trend” within natural products, the market segment has quickly evolved into one of the fastest growing  supplement categories in the industry. Just three years ago, the North American functional mushroom supplements market was valued at USD $541.77 million. Expected to grow at a CAGR of 15.0% from 2024 to 2030, consumer demand for these supplements and their health benefits has led key industry players to innovate and develop next-generation offerings, with adaptogenic mushrooms at the forefront.

The wellness benefits of mushrooms have been documented throughout history. A staple in Traditional Chinese Medicine (TCM) and Ayurveda, beneficial properties have helped fuel the booming mushroom supplements market popular among today’s health-conscious shoppers, especially Gen Z and Millennials. 

To better position themselves in the thriving market, brands have taken some of the most sought-after attributes—cognitive health support, stress relief, and immune support, to name a few—and made them available in easy-to-consume formats including capsules, powders, and gummies. Expanded availability has also opened the door for brands outside the supplement space to enter the conversation with offerings ranging from Ready-to-Drink (RTD) beverages to snacks and sauces, allowing consumers to easily incorporate functional mushrooms and their benefits into daily routines.

Popular Functional Mushrooms and Their Benefits

Cognitive, immune, and stress support drive interest, and the overall growth of the wellness market has led to several mushroom supplements becoming household names. Among the most popular are:

Lion’s Mane: Known for its antioxidant and anti-inflammatory properties, this variety supports cognitive function, including memory, focus, and nerve growth factor (NGF) synthesis. Research indicates lion’s mane may help reduce anxiety and depression. In a 2023 study, researchers observed beneficial effects on gut health, concluding that oral consumption created a prebiotic-type effect by promoting the growth of beneficial gut bacteria while reducing pathogenic bacteria.

Reishi: Consumers are interested in its impact on immune function, lowering triglycerides, supporting mood, and stress management. A recent animal study examined various formulations containing reishi extracts for anti-fatigue and sleep-support effects.

Cordyceps: These mushrooms are prized for their athletic performance-boosting and anti-inflammatory properties, as well as their potential to reduce fatigue, support heart health by lowering cholesterol, regulate the immune system, and support libido. Research suggests supplementation may lead to improvements in time to exhaustion and relative peak power output.

Turkey Tail: This mushroom is known for supporting immune system and gut health.

Chaga: Favored for its immune-supporting function and inflammation reduction, this mushroom is sought after for its ability to support heart health, help manage blood sugar levels, and provide liver protection.

Maitake: Sought after for immune support, maitake may also support metabolic health by helping regulate blood sugar, aiding weight management, lowering blood pressure, and providing antioxidant benefits that promote overall vitality and healthy aging. WF

Ask WholeFoodsMag AI powered by SGS Nutrasource answers the question: What is the debate over functional mushrooms?

Labeling transparency: Whether products that contain mycelium but not fruiting bodies can be marketed as “mushrooms.”

Nammex filed a citizen petition in 2023 urging FDA to enforce labeling that identifies the fungal part used. Host Defense and others countered that mycelium is a legitimate mushroom component and that the petition misrepresents mycological terminology. The petition is pending. FDA has not issued new guidance, but the debate has heightened scrutiny of ingredient disclosure.

Quality control: Some express concerns over labeling, including of mushroom products containing grain substrates.

Nammex and others point to a potential allergen hazard of unreported grain. Host Defense explains the process and benefits of "myceliated grain." On all sides of the debate, brands call for traceability and quality testing.
