Ergothioneine is a naturally occurring antioxidant found in mushrooms that humans have consumed for millennia. Interestingly, some populations with diets rich in ergothioneine-containing foods have been associated with better health outcomes. But what makes this compound so special?
Antioxidants are compounds that protect our cells by neutralizing unstable molecules called free radicals, preventing or slowing cellular damage known as oxidative stress. Free radicals are highly reactive molecules with unpaired electrons that can damage proteins, lipids, and DNA. Antioxidants help keep these molecules in check.
Here at Brain Wave, we have a research collaboration with Penn State University, home to one of the leading experts on ergothioneine (ERGO), Dr. Robert Beelman. We've worked with Dr. Beelman and his team to measure ERGO levels in our products, and the results showed high levels of this important antioxidant. So, let's break down some of the fascinating science behind ERGO and the research Dr. Beelman has helped bring to light.
In 2005, a key discovery revealed that mammals possess a specialized transporter protein that allows ERGO to be absorbed from food and transported into cells throughout the body (https://pubmed.ncbi.nlm.nih.gov/15795384/). This transporter, known as OCTN1 (also called SLC22A4), helps explain why ERGO accumulates in certain tissues, particularly those exposed to oxidative stress. Unlike many other dietary antioxidants, ERGO has its own dedicated transport system. That's pretty amazing, and it suggests our bodies have evolved a specific mechanism to retain this compound.
ERGO has even been proposed as a "longevity vitamin," a term used to describe dietary compounds that may help protect against the cumulative damage associated with aging
. Although ERGO has not been officially classified as an essential vitamin, research suggests it may play an important role in maintaining long-term health and aging.
Dr. Beelman and other researchers have highlighted ERGO's antioxidant and anti-inflammatory properties, which may help protect cells against processes involved in chronic diseases such as cardiovascular disease, neurodegenerative disorders, and certain cancers. Interestingly, studies have also reported declining ERGO concentrations in the blood with age, particularly among individuals with Parkinson's disease, Alzheimer's disease, and cognitive impairment. These findings are especially interesting to us at Brain Wave because supporting brain health is central to what we do.
But the potential benefits of ERGO extend well beyond the brain.
A study involving 3,236 individuals in Sweden examined 112 metabolites and identified ERGO as the metabolite most strongly associated with a healthier dietary pattern and reduced cardiovascular risk (https://pubmed.ncbi.nlm.nih.gov/31672783/). Higher circulating ERGO concentrations were associated with a lower risk of cardiometabolic disease and mortality.
While some foods, including beans, animal liver, and oats, contain ERGO, fungi are among its primary biological producers, and mushrooms are particularly rich dietary sources. Dr. Beelman has emphasized that mushrooms provide more than just ERGO. They also contain other valuable nutrients and bioactive compounds, including selenium, glutathione, and, in some cases, vitamin D. This unique combination makes mushrooms an intriguing dietary option for supporting long-term health.
Dr. Beelman has also highlighted an interesting difference in ERGO consumption between countries. Estimates suggest that Americans consume approximately 1 mg of ERGO per day, compared with roughly 5 mg per day in Italy, where dietary patterns include more ERGO-rich foods like mushrooms. That's a fivefold difference! These dietary differences have prompted researchers to investigate whether greater ERGO consumption might contribute to healthier aging.
At Brain Wave, we believe in the science, and the growing body of research on ERGO is exciting. From its specialized transporter to its potential role in protecting cells against oxidative stress and inflammation, ERGO is much more than just another antioxidant.
Don't get left in the dust. Get your ERGO on.
Best,
Dr. Andy
