      Maitake is a wild mushroom that is largely considered by Asian cultures, especially the Japanese, to have medicinal and functional benefits to the human body. Maitake is one of the most widely-cultivated mushrooms in the world alongside button mushrooms, shiitake, and oyster mushrooms. 

      Maitake mushrooms are usually found growing in clusters at the base of oak trees in various parts of Asia. They can sometimes be found on elms or maple trees.

      It’s important to consider that maitake consumption may increase bleeding and to be careful when taking maitake mushrooms if you’re also taking blood-thinning medications (e.g., warfarin). It’s also recommended to not mix maitake with komen - a diabetes or blood pressure medication. 

      Please consult your doctor about maitake if any of these scenarios apply to you and to discuss whether you’re on any medications which may interact with maitake.

      How do most people take maitake mushrooms?

      If you’ve decided that maitake is the supplement for you, there are a number of ways to consume this nutrient-filled mushroom. Let’s look at the most popular ways people take maitake:

      • Tincture: Maitake tincture comes in a small bottle with a dropper. These nearly tasteless droplets can be added into drinks, onto food, or simply taken by mouth. 
      • Extract powder: As with many other mushroom supplements, extract powder mixed into tea, coffee, or your favorite beverage is a popular way to consume maitake mushroom supplements. Additionally, people may steep the extract powder as a tea as an additional hot water extraction method to make the nutrients more bioactive and easier to break down.
      • Capsules: People who prefer not to take powdered mushroom supplements utilize capsules to consume nutrient-rich maitake. If you decide to take capsules, ensure you’re looking for maitake D-fraction - which is an extract of the mushroom - in your capsule product description. 
      • Raw mushroom powder: Unlike many other mushroom types, there are studies where people took raw maitake powder as part of cancer trials. If you’d like to take raw mushroom powder, you can consume it similar to extract powder - either adding some to your favorite beverage or steeping it as a tea itself.

      The good news? There is no wrong way to take a maitake supplement - it’s just important to find the best supplement format for your personal preferences!


      When is the best time to take maitake supplements?

      It is recommended to start taking maitake daily at a lower dosage to evaluate symptoms. Over time, you can adjust your dosage. There is no information at this time that indicates a specific time of day being best for supplementation, but it’s encouraged to play around with timing to see what works best for you personally.
