SIRT
Sirtuin activation
The longevity “guardian” proteins tied to fasting.
What it does
Sirtuins are NAD+-dependent enzymes that regulate DNA repair, inflammation and metabolism. They’re a headline target of longevity research.
In plain english
Sirtuins are caretaker proteins that keep your DNA tidy — and they work better when NAD+ is plentiful.
The surprising bit
Resveratrol, the compound behind the “red wine” longevity headlines, is a classic sirtuin activator.
