Reishi mushroom, scientifically known as Ganoderma lucidum, is a medical fungus with healing abilities. Native to the hot and humid climate of Asia, this mushroom is commercially and pharmacologically the most important superfood mushroom. 

Rightly called the king of mushrooms, Reishi is an adaptogenic fungus that has been valued for its immune-enhancing, sleep-promoting, and  cancer-fighting properties. However, for users to benefit from the mushroom without dealing with red reishi side effects, they need to understand how much Reishi per day to take. The exact Reishi mushroom dosage depends on the form of the mushroom and the intention of using it.

How To Consume Reishi Mushroom?

Before we show you reishi mushroom dosage for weight loss and other conditions, you may want to know the ideal way of taking reishi products. Reishi mushrooms can be consumed whole in their fresh form. 

While Reishi mushroom health benefits testimonials indicate that the fresh reishi mushroom is effective, the fresh mushroom has the least appealing taste among the superfood mushrooms. It is a deliciously bitter fungus due to the presence of triterpenes. 

Reishi mushroom flavor is reminiscent of dark bitter chocolate. Many individuals may not be able to tolerate this Reishi mushroom taste. This suggests that even people seeking the reishi mushroom benefits for PCOS may not have the ability to use the raw, uncooked Reishi. 

So then, what is the best way to take Reishi mushroom? The answer is mushroom supplements.

Reishi mushroom supplements are available in powders, capsules, extracts, and tinctures. The Ganoderma lucidum supplement powder is made by drying and grinding the mushroom. 

Now you might wonder how to use Reishi mushroom powder? The powdered mushroom is very versatile and can be placed inside capsules, making it easier to take as a daily supplement. However, when taking this form of the reishi mushroom, one has to take the necessary precautions to avoid overconsuming the supplement and ending up with reishi capsules side effects. 

In addition to being used in capsules, reish powder can also be mixed in juice, smoothies, milk, and other beverages. You can put the mushroom powder in a mug of hot water. Allow the powder to simmer for 5 minutes. You can also add your favorite tea, honey, or milk.

The traditional way of consuming the mushroom is fully grown fresh forms. Research evidence shows that the mushrooms were dried and cut into slices in Chinese medicine. They were subsequently boiled in hot water and used in soups and tea as traditional medications. 

The modern-day extraction of the mushroom is inspired by this traditional way. The mushroom is boiled at a high temperature which allows the active ingredients to be extracted in the form of tinctures.

There are several debates on when and how to use Reishi mushroom. The mushroom can be used in any form, as it has been tested at the cellular level in both animal models and human beings. 

Information from scientific studies shows that when an ideal reishi mushroom dose is used, the consumers do not have to be concerned about safety.

When To Take Reishi Mushroom?

Before we go ahead and show you reishi mushroom powder dosage, we will help you understand when you should consume the mushroom. 

According to research, there is no best time to take mushroom supplements. Some say that the mushroom is the most effective if you take it on an empty stomach first thing in the morning. Taking the powder mixed with a glass of water or pairing the powder with food rich in vitamin C helps proper absorption. You can also pair the mushroom with a cup of tea or coffee.

Traditional eastern medicine recommends taking Reishi mushroom in the evening around bedtime—this is especially ideal for people trying to figure out the right reishi mushroom dosage for sleep.

How Much Reishi Mushroom Should I Take?

How Much Reishi Mushroom Should I Take?

Reishi mushroom dosage recommendation varies based on the form used. For example, reishi mushroom tincture dosage will be very different from the dosage for fresh mushrooms. 

When the fresh form of the mushroom is consumed, the dose ranges from 25 to 100 gms. This dose depends on the size of the mushroom. Reishi powder dosage is generally 10 times lower than when the mushroom is consumed in its fresh form. So 50 grams of fresh Reishi mushroom is equivalent to 5 grams of the supplement extract.

The quantity for consumption is lower with supplements, as they are more concentrated. Hence, small amounts are required to achieve the same benefit as with fresh mushrooms. The general oral dose of dried mushroom is 1.5-9g/day. 

The Reishi mushroom powder dosage is 1-2g/day, and the dose for the tincture is 1ml/day. A daily dose of 2g of the mushroom powder containing 20% beta-glucans provides 400mg of the polysaccharides present in Reishi.

How much Reishi per day is also highly dependent upon the underlying condition for which it is being taken. This means that the reishi mushroom cancer dosage will be very different from the dosage for someone using a reishi product to improve immunity or lower high blood pressure.

Reishi Mushroom Cancer Dosage

There are limited reports of human trials using Reishi as an anti-cancer agent to date. A 12-week supplementation of Reishi capsules, at dosages of 1800 mg, caused cellular immunological enhancements in cancer patients. These are the results of two randomized control trials that used the mushroom component Ganopoly on 34 patients with advanced cancer.

Water-extracted Reishi mushroom supplements decreased(2) the size of cancer cells in colorectal cancers when taken in a dose of 1.5g/day for 12 months.  

The methanolic extract of the triterpene has a direct lethal effect(3) on cancer cells at a dosage of 450 microgram/ml. The water extract of the fruiting body has an inhibitory effect on cancer cells in dosages of 509 microgram/ml. This study was conducted on animal models. With these results, the future of Reishi as an anti-cancer agent seems promising.  

Dose In Hepatoprotection

10, 30, and 100 mg/kg body weight of 4.41% water extract of Ganoderma lucidum have a potent hepatoprotective action on carbon tetrachloride-induced liver injury in animal models(4).

Antioxidant Dosage Of Reishi Mushroom

The triterpenes and polysaccharides of the mushroom have shown excellent antioxidant activity(5). If your goal is to benefit from the mushroom antioxidants, a dose of 0.6 mg/mL should be ideal.

Dose In Diabetes

1800mg of ganopoly containing Reishi mushroom supplement, given thrice daily, reduces postprandial glucose levels.

Reishi Mushroom Dosage In Gastro-Protection

0.1, 0.5, or 1.0 g/kg of the polysaccharide fraction of Reishi conferred protection against an acetic acid-induced gastric ulcer in mouse models. This once-daily(6) dose of the mushroom, when given for 14 consecutive days, causes significant acceleration of ulcer healing by up to 56%.

Dose In Asthma

A herbal supplement containing 62.5% of Reishi mushroom was given twice daily for one week. The mushroom was given in doses of 600 mg, 1200 mg, and 1800 mg. This dose was well tolerated by allergic subjects.
