Question 46 of 433
Should I buy one of these tests?

The short answer
Only if you understand it is a curiosity, not a diagnosis. It should never replace standard testing, and you should never pay for a treatment because of it.
The tests cost roughly $200 to $500. If seeing a number motivates you to exercise, that has value. But I have three cautions. One: we do not know that lowering your clock number lengthens your life. Two: results vary enough that a “three-year improvement” may be noise. Three: some companies that sell the test also sell the supplements that claim to fix it. That is a conflict of interest, and you should treat it as one.
