We are awash in longevity tests and services. There are ones that measure your blood, others that measure the quality of your DNA and others that check on your gut and brain. You can Blueprint, Viome, Function Health and on and on.

To figure out how at least one of these longevity programs actually works, we decided to have Dugal Bain-Kim from Lifeforce on the pod.

As you will notice, the dude is jacked and does indeed seem quite healthy.

Lifeforce provides - for a montly fee - a lot of what a decent national healthcare system might do in a different universe. It sends a phlebotomist to your home to take a blood draw and performs a wide range of tests on the sample. It then puts you in touch with a medical team for some health counseling and tries to identify areas that will help you become a better you.

Instead of doing this once, you repeat the cycle every three months and try to push what the company calls your Lifescore ever higher.

Bain-Kim is not a doctor and comes from the business world, and two of Lifeforce’s co-founders are Tony Robbins and Peter Diamandis. Robbins obviously has a reputation as a self-improvement guru, and some of Diamandis’s ventures center on selling optimism. The company also offers supplements and other products. This combination of things will put some people off.

That said, Lifeforce also has a deep medical bench, and there’s real – and ever-improving - science backing up its measurements and therapies.

I’m broadly excited for services like Lifeforce but also fearful that consumers have little means of judging these various programs and separating the good stuff from the snake oil.

We touch on all of these issues and much more in the show. Have a listen and judge for yourself.
