A biological age.
Starting today.
bettr.now turns a blood test and your wearable into one clear, movable measure of your health, your biological age. You get actionable insights on how to lower your biological age and increase your longevity.
Comprehensive blood testing is launching soon. You don't have to wait - start today with results you already have, or a two-minute questionnaire.
6 years younger than your actual age. Upload a blood test to turn this estimate into your real, tracked biological age.
Meet the age your body is actually living at.
The age on your passport is fixed. Your biological age isn't.
It's a single number built from what's actually happening inside you, and it's designed to be lowered. See where you stand today, understand why, and get the specific changes that move it.
