The Best Reishi Supplements – Top 5 in 2026

Yango’s Reishi is a dietary supplement containing Ganoderma lucidum mushroom extract, standardized to 10% polysaccharides—the active compounds responsible for its health-promoting properties. Each capsule provides 360 mg of extract, including 36 mg of polysaccharides, which support immunity, cardiovascular health, and cholesterol regulation. The bioactive beta-glucans in the extract may also help the body fight infections and oxidative stress. Testers appreciated Yango’s Reishi for its pure formulation—free of additives and fillers. They also liked the vegan capsule coating, which is gentle on those with sensitive stomachs. However, attention was drawn to the supplement’s lower yield—one package lasts only 45 days, which is two weeks shorter than the competing Nutridome product, which, at a lower price, also offers a higher dose of extract (400 mg vs. 360 mg). For those seeking daily support for immunity and circulation, Reishi Yango is a good choice, but not necessarily the most economical one.

The Aura Herbals Reishi Spores dietary supplement is a combination of red Reishi mushroom spore extract and vitamin C. Reishi spores are the most concentrated source of polysaccharides and triterpenes—compounds that support the immune system, reduce inflammation, and improve overall well-being. The addition of vitamin C boosts immune function and helps reduce fatigue. Our testers praised Aura Herbals’ Reishi for its pure formula, lack of artificial additives, plant-based capsule, and carefully balanced ingredient ratios. The supplement was particularly appreciated by testers on a plant-based diet. Unfortunately, the package lasts only 30 days, and with a double dose, the yield is lower than in competing products, which may affect the price-to-treatment-duration ratio. Testers also noted that the capsules are difficult to swallow. It’s an interesting option for those looking for a highly concentrated, natural form of Reishi, but it didn’t become our testers’ favorite product.

MycoWay Reishi is a supplement containing as much as 1,950 mg of 5:1 Reishi mushroom extract per daily serving (3 capsules), which is equivalent to nearly 10 grams of raw material. Testers appreciated its strong immune-boosting effects and positive impact on circulation, especially during periods of weakness. They also noticed an improvement in their well-being and a reduction in feelings of chronic fatigue. The product stands out for its high concentration of bioactive substances, particularly polysaccharides and triterpenes, known for their immunomodulatory and anti-inflammatory effects. Among the drawbacks, testers pointed out the need to take as many as three capsules a day, which can be cumbersome and significantly reduces the convenience of use. The testers also noted the large size of the capsules. Additionally, some testers experienced mild stomach discomfort, especially when taking the supplement on an empty stomach. For some testers, the concentration of the active ingredient was too high, requiring them to discontinue the treatment. The supplement is expensive, and its availability is limited.

UNS Reishi is a supplement containing 400 mg of Reishi extract standardized to 40% polysaccharides. Our testers noted that this is a very concentrated dose. Our testers observed positive effects, such as improved immunity and better concentration, and they also appreciated the eco-friendly glass packaging. However, with such a potent effect, there were also clear drawbacks. Some testers experienced headaches, nausea, and trouble falling asleep, especially when taking it in the evening. The product may also not be suitable for people with high blood pressure or a sensitive stomach. Some testers reported symptoms such as stomachaches and heartburn. Testers also noted that the formula lacks, for example, vitamin C, which could aid in the absorption of the active ingredients. While the price isn’t very high, given the risk of side effects, not everyone will be satisfied with purchasing this supplement.
