Common questions
Does NSF Contents Certified (NSF/ANSI 173) mean the product has none of the additives we check for? Not on its own. The seal's definition says what it covers. We check the other ingredients on the label, separately.
Know whether a supplement suits you. The iPhone app checks it against your own blood test, then shows who said so, on video.
Best for: blood test results you already have, from any lab, explained for your age and sex. Not for: ordering a new test, a diagnosis, or Android phones.
Free for 7 days at launch, then $12.99 a month or $79.99 a year.
