Ergothioneine is a powerful antioxidant and amino acid that your body can’t produce on its own, but it's essential for protecting your cells from oxidative stress and supporting long-term health. Sometimes referred to as the "longevity vitamin", ergothioneine accumulates in vital organs like the brain, liver, heart, and eyes, where it plays a protective role.
Naturally found in mushrooms and a few rare food sources, dietary intake of ergothioneine is often too low for optimal benefit. Charava’s 25mg L-Ergothioneine provides a convenient, concentrated dose to help fortify your body’s defences.

DO YOU FEEL LIKE EVERYDAY STRESS IS CATCHING UP WITH YOU FASTER THAN IT USED TO?
From normal metabolism to environmental stress, your cells deal with oxidative pressure every day. Ergothioneine is a naturally occurring antioxidant that accumulates in tissues throughout the body, helping support cellular protection and healthy ageing.
Focused daily Ergothioneine support for cellular protection and healthy ageing.


"Started this as part of my longevity stack. Can't say I feel a dramatic difference day to day but I trust the science and it's easy to take."
"Added this alongside my other supplements for the long-term ageing support. No issues taking it and feels like a sensible, considered choice."
"I like knowing I'm doing something proactive for my health long term. Easy to fit into my routine and no side effects at all."
Ergothioneine provides targeted antioxidant support for cellular protection, mitochondrial health and healthy ageing.

Problem
Normal metabolism and everyday environmental exposure continually generate oxidative stress that your cells need to manage.
Solution
Ergothioneine is a naturally occurring antioxidant that helps support the body's cellular defences against oxidative stress.
Problem
Some tissues face particularly high levels of metabolic and oxidative stress because of the work they perform every day.
Solution
The body has specific transport systems for Ergothioneine, allowing it to accumulate in tissues where cellular protection may be valuable.
Problem
Mitochondria generate energy for your cells but are also exposed to oxidative stress as part of normal energy production.
Solution
Ergothioneine provides antioxidant support that may help protect mitochondria and maintain healthy cellular energy processes.
Problem
Oxidative stress accumulates over time and can place increasing pressure on normal cellular maintenance as we age.
Solution
By supporting antioxidant defences, Ergothioneine helps protect cellular health and the processes associated with healthy ageing.
Problem
Ergothioneine occurs naturally in certain foods, particularly mushrooms, but everyday intake can vary considerably between diets.
Solution
Supplementation provides a consistent daily source of Ergothioneine without relying solely on dietary intake.
Problem
Long-term cellular support works best when it is easy enough to make part of your everyday routine.
Solution
A focused daily Ergothioneine formula provides simple, consistent antioxidant support without adding unnecessary complexity.

Charava delivers a focused daily source of Ergothioneine, a naturally occurring antioxidant found in certain foods and human tissues.
Ergothioneine helps support cellular antioxidant defences and is transported into tissues where protection against oxidative stress may be valuable.
A simple daily formula provides consistent Ergothioneine support without relying on dietary intake alone.
