Ergothioneine is a naturally occurring metabolite of histidine, found in many different foods, with particularly high amounts in mushrooms. It is an amino acid betaine with antioxidant and anti-inflammatory properties. Research suggests that ergothioneine may have a positive impact on brain health and cognitive performance. As ergothioneine is only biosynthesized by fungi and mycobacteria, mushrooms are a leading dietary source of this compound. While some mushrooms, like the common white button mushroom, contain negligible amounts of ergothioneine, others, such as the shiitake and oyster varieties, are rich sources.
So, how many white mushrooms would one need to consume to obtain 3 milligrams of ergothioneine?

White button mushrooms contain negligible amounts of ergothioneine
Ergothioneine is a sulfur-containing amino acid that acts as an antioxidant and is widely distributed in most mammalian tissues. It is a naturally occurring metabolite of histidine found in many different foods, with the highest amounts found in mushrooms.
However, not all mushrooms contain the same levels of ergothioneine. Some varieties, such as the chanterelle (Cantharellus cibarius) and the common white button mushroom (Agaricus bisporus), contain negligible amounts of ergothioneine.
White button mushrooms are the most commonly consumed mushrooms, comprising 35-45% of total worldwide edible mushroom consumption. They are widely cultivated throughout Europe and North America and are popular due to their year-round availability, safety, and consumer acceptance.
While white button mushrooms do contain some ergothioneine, the amount is significantly lower compared to other mushroom varieties. For example, a standard serving of 100g of white button mushrooms contains only about 3.2 mg of ergothioneine. In contrast, oyster and shiitake mushrooms are known to have higher levels of ergothioneine and are more suitable options for those seeking this compound.
If you are specifically looking to consume higher amounts of ergothioneine, it is recommended to choose mushrooms with maximum amounts, such as oyster and shiitake varieties, or consider taking ergothioneine supplements. These supplements are derived from mushrooms and yeast, providing a convenient way to obtain the potential health benefits associated with this compound.

Portabellas and criminis mushrooms have the highest levels of ergothioneine
Mushrooms are a leading source of ergothioneine, a unique metabolite produced by fungi with strong antioxidant properties. They are a better natural source of this antioxidant than wheat germ and chicken liver, the previous top-rated ergothioneine sources.
The white button mushroom, or Agaricus bisporus, is the most commonly consumed type of mushroom in the U.S. and has been found to contain about 12 times more ergothioneine than wheat germ and 4 times more than chicken liver.
If you're looking for mushrooms with high ergothioneine content, oyster and shiitake mushrooms are easy to find and offer their own unique health benefits. King oyster, maitake, and enokitake mushrooms also contain greater amounts of ergothioneine.
The potential health benefits of ergothioneine are numerous, and research is ongoing. Evidence suggests that ergothioneine may act as an antioxidant and anti-inflammatory, promoting healthy ageing and preventing inflammatory diseases. A longitudinal study found that higher plasma levels of ergothioneine correlated with a decreased risk of cardiovascular-related diseases and a reduced mortality rate.

Oyster, shiitake, king oyster, and maitake mushrooms are rich sources of ergothioneine
Mushrooms are a leading source of ergothioneine, a potent antioxidant and anti-inflammatory amino acid that is highly bioavailable to humans from dietary sources. While ergothioneine was discovered over a century ago, research in recent decades has revealed its many health benefits.
The shiitake mushroom (Lentinula edodes) is another variety that contains high amounts of ergothioneine. In fact, it has about four times the amount of ergothioneine as the common white button mushroom (Agaricus bisporus), which contains negligible amounts.
Consuming mushrooms is one simple way to enjoy the benefits of ergothioneine. The beta-D-glucans in mushrooms like shiitake and oyster also help to boost the immune system. Ongoing research continues to investigate how ergothioneine interacts with the human body and its potential health benefits.
Mushrooms are fat-free, cholesterol-free, gluten-free, low in sodium, and low in cholesterol. They are also a good source of vitamin D, B vitamins, potassium, and antioxidants. Incorporating mushrooms into one's diet can be as simple as blending them with meat or adding them to stir-fries, burgers, meatballs, tacos, omelets, pizza, and pasta sauce.

Mushrooms are a major dietary source of ergothioneine
Ergothioneine is only biosynthesized from fungi (including edible mushrooms) and mycobacteria. It has also been found in human and mammalian tissues, with the highest concentrations in the liver, kidney, and whole blood of pigs and rats. In humans, it is present in the male blood at different stages of life, increasing gradually between 11 and 18 years and reaching its maximum value of 3.7 mg/100 mL at 18 years of age.
Mushrooms contain the most significant amounts of ergothioneine, with some varieties containing higher levels than other foods. The King oyster, maitake, oyster, and shiitake mushrooms contain the highest amounts of ergothioneine. The chanterelle and common white button mushroom contain negligible amounts. A serving of mushrooms can contain 2.4 to 4.9 mg of ergothioneine.
The health benefits of ergothioneine are numerous. It acts as an antioxidant, protecting mitochondria from oxidation, and has anti-inflammatory properties. Research has found that higher plasma levels of ergothioneine are associated with a significantly lower risk of coronary disease, cardiovascular mortality, and overall mortality. It may also support cognitive function and mitigate the effects of photoaging in the skin.
Mushroom supplements are available for those who want to increase their ergothioneine intake. However, it is important to speak with a healthcare provider before taking any supplements, especially if one has a chronic illness or is on medication.

Ergothioneine is a sulfur-containing amino acid with antioxidant properties
Ergothioneine, a sulfur-containing amino acid with antioxidant properties, was discovered in 1909 by French pharmacist and chemist Charles Tanret. Tanret found ergothioneine by examining the ergot fungus, which had been destroying crops. The amino acid was named after this fungus.
Ergothioneine is a naturally occurring metabolite of histidine, an amino acid betaine (2-mercapto-histidine trimethylbetaine). It is found in many different foods, with particularly high amounts in mushrooms. It is synthesized by bacteria and fungi, and accumulates in higher organisms at high levels via an organic cation transporter (OCTN1).
The physiological role of ergothioneine is still being researched, but it has been found to have antioxidant and cytoprotective capabilities. It acts as an antioxidant by protecting mitochondria from oxidation. It also has anti-inflammatory properties, and can cross the blood-brain barrier, potentially offering benefits to brain health.
Mushrooms are a top source of ergothioneine, with some varieties containing more than others. The King oyster, maitake, oyster, and shiitake mushrooms contain the highest amounts. The common white button mushroom (Agaricus bisporus), on the other hand, contains negligible amounts of ergothioneine.
To obtain 3 milligrams of ergothioneine from white button mushrooms, one would need to consume a significant amount, as the exact quantity required exceeds a typical serving size. A serving of mushrooms typically contains 2.4 to 4.9 milligrams of ergothioneine.
