L-Ergothioneine Supplement – Brain, Antioxidant, Immunity


+ Minimal Shipping

L-Ergothioneine is natural, sulfur-containing amino acid that has garnered attention in recent years in the world of health and nutrition due to its potent properties, such as an antioxidant, the cellular protection, and neuroprotective effects.


L-Ergothioneine Supplement 1% is natural, sulfur-containing amino acid that has garnered attention in recent years in the world of health and nutrition. Scientists are constantly exploring new compounds and substances that offer benefits to human well-being and L-ergothioneine is a derivative with potent antioxidant properties. It is merely produced by fungi and bacteria, so mammals need to get the amino acid it from external sources.

We find L-ergothioneine in various dietary sources in minuscule amounts, such as in beans, grains, pork, and chicken, albeit a vastly superior source are certain mushrooms that have concentrations hundreds of times higher than other sources. That is still only a small fraction of the 1% extract.

It has sparked interest for its alleged ability to combat oxidative stress and support overall health. It supports the cell to produce energy as ATP at the mitochondrial level, which helps cell regeneration.


L-ergothioneine is primarily known for its robust antioxidant capabilities. When our bodies face oxidative stress due to an imbalance between free radicals and antioxidants, it can lead to cellular damage and contribute to the development of various diseases, including cancer, cardiovascular disorders, and neurodegenerative conditions. As an antioxidant, L-Ergothioneine helps neutralize free radicals, protecting cells and tissues from damage.

Cellular Protection

Beyond its antioxidant properties, L-ergothioneine also plays a crucial role in cellular protection. Studies suggest that this compound can accumulate and concentrate within cells that are exposed to stress or inflammation, providing an added layer of protection to these vulnerable cells. By supporting cellular health, L-Ergothioneine may potentially slow down the aging process and reduce the risk of age-related diseases.


Research has indicated that L-ergothioneine may have neuroprotective properties, making it a promising candidate for age-related cognitive decline. These neuroprotective effects are believed to be linked to its ability to scavenge harmful reactive oxygen species in the brain and reduce inflammation.

Immune System

A well-functioning immune system is vital for maintaining good health. L-ergothioneine antioxidant properties can help support the immune system by reducing oxidative stress and inflammation. By doing so, it may contribute to overall immune health and better disease resistance.

Suggested use

The suggested daily dose for adults is 1,000 mg – 3,000 mg. This amount corresponds to 10 mg – 30 mg of pure L-Ergothioneine a day.
