At Natural Essence is L-Ergothioneine offers ingredient clean, concentrated, and highly bioavailable supplement that supports longevity and vitality. committed to supplying you with the highest quality, most effective powders.
Ergothioneine (ET) is a naturally occurring sulfur-containing amino acid derived from histidine. Unlike most nutrients:
- It is not produced by the human body
- It must be obtained from diet or supplementation
- It accumulates in critical tissues such as the brain, liver, and kidneys
Scientific research shows that ergothioneine is transported into cells via a specific transporter (OCTN1), highlighting its biological importance.
Why Do Scientists Call It a “Missing Vitamin”?
① The Body Cannot Produce It
Humans rely entirely on dietary intake, similar to essential vitamins.
② It Has a Dedicated Transport System
The body actively absorbs and retains ergothioneine through specialized transporters, suggesting biological necessity.
③ Deficiency May Impact Long-Term Health
Low levels are associated with:
- Cognitive decline
- Cardiovascular risk
- Increased oxidative stress
④ It Supports “Longevity Functions”
According to the triage theory, nutrients like ergothioneine may protect long-term health rather than prevent acute disease, leading to its nickname:
👉 “Longevity vitamin” or “missing vitamin”
What Are the Natural Sources of Ergothioneine?
L-Ergothioneine is synthesized only by fungi and certain bacteria.
Rich Dietary Sources:
- Mushrooms (highest concentration)
- Fermented foods
- Whole grains
- Organ meats
However, modern diets often contain insufficient levels, making supplementation increasingly relevant.
