I would not put much trust into some poorly-understood biomarkers, especially ones that have grandiose naming like epigenetic age. The naming alone implies more than I suspect these markers can deliver.
The price is also kinda ridiculous, $70 a day for meals and supplements.
Especially when an example of a biomarker is ability to hear out of the left ear. Yes, fixing that (if you could) could improve your quality of life, but unless there's a train coming from the left side, it won't make you live longer.
Those tests also seem ripe for the nocebo effect.
All this testing and measuring seems a coping mechanism for trying to find and control some sort of objective measures in squishy, uncertain, biology.
