Ergothioneine 5mg, 60 Capsules

What Is Ergothioneine?

Ergothioneine is a naturally occurring amino acid found abundantly in certain mushrooms, such as white button, shiitake, and oyster varieties. Unlike many other antioxidants, ergothioneine is remarkably stable and accumulates in tissues most vulnerable to oxidative stress, including the liver, kidneys, and brain. Each capsule provides 5 mg of L-ergothioneine, the bioactive form, equivalent to the amount found in 2 to 5 cups of white button mushrooms. This makes it a convenient way to boost your intake of this unique nutrient.

Who Should Consider Ergothioneine?

Ergothioneine is an excellent addition for anyone interested in supporting their general health and wellbeing. It may be particularly beneficial for those who wish to increase their antioxidant intake, especially as ergothioneine levels tend to decline with age. Adults looking to complement a diet low in mushrooms, or those concerned with maintaining healthy ageing, may find supplementation useful. Because ergothioneine is rich in mushrooms, vegetarians and vegans who consume mushrooms may already obtain some, but a supplement ensures a consistent daily dose.

What Research Suggests

Ergothioneine is thought to play a role in protecting cells from oxidative damage, a factor in the ageing process. Preclinical research indicates that L-ergothioneine may help maintain telomere length under oxidative stress, which is associated with cellular health. Additionally, lower levels of ergothioneine in older adults have been linked with cognitive decline, and some studies suggest it may support cognitive health. The antioxidant benefits of ergothioneine may also extend to vision and heart health; a 2020 clinical study found that higher ergothioneine levels were associated with healthier diets and better heart health markers. Furthermore, a mouse study observed a 21% increase in life span with supplementation, whilst human research is still emerging. These findings point to the potential of ergothioneine in supporting the body's natural defences over time.

What to Look for in an Ergothioneine Supplement

When choosing an ergothioneine supplement, consider the dosage. Most research undertake 5–10 mg per day, so a 5 mg capsule is a sensible starting point. Look for L-ergothioneine, the naturally occurring form, as it is the bioactive isomer. Purity matters—avoid supplements with unnecessary fillers, additives, or synthetic ingredients. Third-party testing for potency and contaminants can provide extra confidence, whilst not all brands disclose this. Healthspan Plus Labs prioritises transparency and undertake only high-quality ingredients.
