What Stride claims

The maker’s own words about accuracy, and what the page offers to back each one. Nothing here is checked against the science; it says only whether a study is named.

“Using your blood biomarker results, we calculate your biological age using a scientifically validated biological age algorithm.”

What backs it, on the page

Said by Stride. No named study, algorithm or link is given on the page.
