Products Description
What is L-Ergothioneine Powder?
1)A naturally occurring rare amino acid, usually biosynthesized by bacteria and fungi, first isolated from the fungus Claviceps purpure in 1909. It was later found to be present in human tissues and organs. It acts as a protective agent and antioxidant for cells in the human body.
But our bodies can't make it themselves and must get it from the outside world, so eating mushrooms is thought to increase the level of ergothionein in the body.
2) For natural source
It is extract from the mushroom.The specification of L-ergothioneine can be reach 0.5%-1%.L-ergothioneine powder is a natural antioxidant, which can protect cells in human body and is an important active substance in the body.
Compared to vitamin C and glutathione, two old-school antioxidants, ergothioneine is safer, gentler, more stable, and has stronger antioxidant power.

Application of L-Ergothioneine Powder
1.Used in Cosmetic raw materials.
L- Ergothionein, a unique antioxidant and cell protectant, has proven to have a wide range of potential applications in cosmetics, add in essence, cream/lotion, eye cream, sunscreen products, etc.
It is often combined with vitamin C, niacinamide or ferulic acid to make serum. It is combined with hyaluronic acid and ceramide and added to day cream and night cream.The added concentration should be 1%.

Benefits of L-Ergothioneine powder
1. Antioxidant
It can directly react with free radicals to remove active oxygen species in the body, such as hydroxyl free radicals, superoxide free radicals, hydrogen peroxide, etc. This direct clearance mechanism is the basis of the antioxidant effects of ergothionein.
2. It can protect DNA
It can protect DNA from oxidative stress damage, thereby preventing gene mutation and cell death, and can also regulate the expression of genes related to cell cycle and apoptosis, affecting the oxidative stress damage of cells
3.Pprotect cells
Mitochondria are the main targets of many drug toxicity reactions, and the physiological function and homeostasis of cells are closely related to the functional health of mitochondria to a large extent.
When mitochondria are injured, ROS produced by them cannot be effectively removed, which will lead to a malignant positive feedback mechanism, exacerbating the damage of mitochondria and cells until the loss of cell function or apoptosis occurs.
L-Ergothione has a protective effect on mitochondria, which can resist damage caused by natural, disease processes or exogenous factors
