I've been taking this supplement for almost a month now, alongside daily consumption of kombucha for gut health. Research indicates that a healthy gut microbiome can improve the absorption of nutrients, including ergothioneine. My goal for taking this supplement is to prevent the onset of mild cognitive impairment, dementia, and Alzheimer's. There is a substantial body of literature suggesting that ergothioneine may help prevent neurodegenerative diseases. Of course, consuming plenty of mushrooms naturally would be ideal. With supplement, it's difficult to determine its bioavailability, how much of the substance is actually absorbed by the body. Nevertheless, I am willing to give it a try, especially since it's sometimes hard to ensure a sufficient amount of mushrooms in my diet. So far, I haven't been able to determine how well it works towards my main goal, as it's a long-term game. However, I have noticed an improvement in my complexion and fewer hormonal breakouts lately. While it's unclear if these changes are directly related to my ergothioneine or kombucha consumption, it's plausible that they are connected, likely due to their antioxidant properties.
