Description
L-Ergothioneine is a naturally occurring thiol compound and a derivative of the amino acid histidine. It is found in various organisms, including fungi, bacteria, and certain plants, and is especially abundant in mushrooms. L-Ergothioneine is recognized for its potent antioxidant properties, helping to protect cells from oxidative stress and free radical damage. It plays a crucial role in cellular health, supporting skin health, reducing inflammation, and promoting overall well-being.
Grifola frondosa (Maitake) and Pleurotus citrinopileatus (Golden Oyster Mushroom) are particularly rich in EGT, with their extract powders containing up to 1.0% L-ergothioneine. These extract powders are also abundant in vitamins, minerals, and organic acids, and provide 18 amino acids required by the human body—over 45% of which are essential amino acids—making them both highly nutritious and beneficial for overall health.
