Amazing Benefits of Royal Sun Agaricus Mushroom

The royal sun mushroom might not be as popular as some of the other mushrooms we have reviewed so far but it doesn’t mean that it’s any less beneficial. The reason for its lack of popularity is that scientists only started noticing the beneficial properties of this mushroom about forty years ago. People that grew around the places from which the royal sun mushroom originates tended to include other mushrooms more often than this one.

The royal sun Agaricus mushroom is an edible type of mushroom and it has a really intense almond flavor. It also has a very unique look so it’s easy to recognize in nature.

What is the Royal Sun Agaricus Mushroom

It has similar properties to both common mushrooms and field mushrooms. It also has some unique compounds that scientists believe could be anti-inflammatory, antioxidant, anti-tumor, and antimicrobial.

Royal sun Agaricus mushroom (aka Agaricus blazei) is a medicinal mushroom that can be mostly be found growing in Japan, China, and Brazil. It has similar properties to both common mushrooms and field mushrooms. It also has some unique compounds that scientists believe could be anti-inflammatory, antioxidant, anti-tumor, and antimicrobial. Natives from Japan and China have used it in traditional medicine for several centuries in order to treat and prevent certain diseases such as diabetes, cancer, and even allergies.

There aren’t many edible royal sun mushrooms you can find in the Western markets, but you can find royal sun mushroom supplements. There are some extracts that can also be used as an addition to food. This mushroom is actually much tastier compared to other medicinal mushrooms because of the almond aroma it possesses.

Health Benefits of the Royal Sun Agaricus Mushroom

The potential benefits of this mushroom have only recently started to be tested on humans. Although there isn’t much research done here are some benefits that show the most promise.


Recent studies, such as the one done in 2017, have shown that the royal sun mushroom might be helpful in treating type 2 diabetes. The researchers reported that this mushroom includes certain compounds like beta-glucan (dietary fiber) and oligosaccharides (a type of carb). Both of these compounds can help regulate blood sugar levels by decreasing inflammatory stress that can occur on the pancreas (the main source of insulin in the body).

The mushroom might even work better when combined with 1500 milligrams of metformin (anti-diabetes drug). This way, the insulin resistance may improve even more and the blood sugar levels can decrease two times more than when patients take the drug alone.

Even though these findings show promise, there is still a lot of research that needs to be done. It is still unclear whether or not the royal sun mushroom can control diabetes by itself or prevent diabetes from occurring in people with pre-diabetes.

Inflammatory Bowel Disease

The royal sun mushroom was most widely used for its anti-inflammatory potentials. It has proven to have a role in treating people with inflammatory bowel diseases (IBD) like Crohn’s disease and ulcerative colitis.

A study done in 2011 examined adults who were diagnosed with Crohn’s disease. The results showed that those who were prescribed oral Agaricus extracts (AndoSan) for two weeks have shown a huge reduction in intestinal inflammation.
The reduction rate was huge, varying from 20% to 80% depending on the inflammatory protein (cytokine) that was taken from the blood and stool tests. These results have proven that the royal sun mushroom might have a future in treating inflammatory bowel diseases. Although, much more studies are needed to determine just how effective this fungus can be.

There isn’t much information on how our bodies react if we take royal sun mushrooms in high doses every day.

Royal Sun Agaricus Mushroom Side Effects

There isn’t much information on how our bodies react if we take royal sun mushrooms in high doses every day. Although the supplement seems to be tolerated well there have been some reports of negative reactions such as stomach problems, diarrhea, and nausea. People that have taken this mushroom in higher doses are the ones that typically experienced side effects. However, these are some mild side effects. What is more concerning is that this mushroom could influence liver enzymes and if the number of these enzymes increases then so does the risk of liver problems.

It’s not recommended that you use this mushroom for alternative cancer treatment. The fact that it might cause liver damages can only have a negative effect on cancer. The royal sun mushroom should be used cautiously if you are on diabetes medications such as insulin. Taking insulin and royal sun mushroom extracts might spike blood sugar levels and cause fatigue, nausea, trembling, dizziness, and fainting.
People that have autoimmune diseases such as psoriasis, lupus, and rheumatoid arthritis shouldn’t use this mushroom either due to a flare of symptoms.
Children, nursing moms, and pregnant women should all avoid using this mushroom in any form until more research has been concluded.

Royal Sun Agaricus Mushroom – Dosage

Agaricus blazei mushroom can be found in the US mostly in a form of dietary supplements. Capsule, tincture, tablet, gel-cap, and extracts are the most common forms. Some natural health and Asian stores might sell them in the form of powder, tea, or they might have freeze-dried mushrooms.

Royal sun oral capsules are usually around 400 to 500 milligrams, and they should be taken once or twice a day. Studies have examined the effects of 1500 milligrams a day for a year but that doesn’t automatically mean that dose is safe or efficient. Unfortunately, there still aren’t general recommendations for royal sun mushroom dosages.
The general rule when trying out new supplementation is to start with a smaller dose and gradually increase it if you don’t experience any negative reactions. Make sure to never go consume more than the dose recommended on the label.

Reminder: When purchasing royal sun mushroom supplements, always choose brands that are labelled as 100% organic. Also, make sure to always read the product label to know exactly what you are purchasing and implementing in your diet.


The royal sun mushroom is a potentially beneficial fungus that can be used for treating a variety of diseases. However, studies on this mushroom are still insufficient and there won’t probably be any steady results for a few more years regarding the royal sun.
If you choose to implement this mushroom into your diet, make sure to first check with your doctor, and if you start experiencing any side effects and negative reactions stop using the supplements immediately and call your healthcare provider.
