Product Description

Do you really know how old you are?


Are you aging faster or slower than your classmates? Your body has two ages, a chronological age, which is how many years you have been on the planet, and biological age, your body's greatest health risk factor.


We measure your biological age.


An epigenetic test measures the dynamic process of methylation in your DNA. Changes in methylation occur with changes in your lifestyle and with aging. DNA methylation testing is a reliable measure of your biological age.


DNA methylation patterns change with age. By measuring them, we can gauge how old you are by the way your genes are currently expressing themselves.


BioViva’s TimeKeeper™ gives you the most data on the market, so your information can grow with scientific discovery.

    Rating: Awesome!

    Showing my age has decelerated by a few years from my biological age, is exciting. A couple of years ago, I did a DNA telomeres test, and the results from another company weren’t as exciting and, it showed I was at a age of 67. So, by continuing daily exercise, increase in NADS, and working on a balanced diet and adding metformin, I’m extremely pleased at the results you’ve shown me with the methylation DNA kit.

    Excellent Service

    I was looking for a research-quality methylation test. After talking with BioViva and their labs I will be using this kit for patients. Thanks, BioViva for doing it right.

    Wonderful Service

    Excuse my English.

    TimeKeeper is great service. Aging kills us and we need to get it under control! That's why I got TimeKeeper. It's why I get it every six months. I want to know how I'm doing. TimeKeeper tells me.

    Keep up the great work!
