The Claim: Sending some saliva or blood to a testing firm that checks your
telomeres (caps on the tips of chromosomes) can reveal if your lifestyle is prematurely aging you.
Oz Says: Don't bother. "For the majority of healthy people, there is no medically indicated reason to have your telomeres tested," says Carol Greider, PhD, who shared a Nobel Prize in 2009 for her research on telomeres. A snapshot of how long yours are doesn't tell you much about how you're aging. There's a huge spectrum of normal telomere lengths, and it's not yet clear what variations in that range mean. You don't need a $300 test to tell you to work on stay-young basics like eating well, relaxing more, and being active. You know that stuff already!
The Verdict: SKIP IT
