Synapse opened my eyes. I had no idea what my lifestyle was doing to my health. Now I'm 10 kilos lighter, I've quit smoking and cut out soft drinks. My biological age went from +12 to +4 — I'm well on my way!

I was insulin resistant with a high cardiovascular risk due to elevated Lp(a) — without knowing it. Synapse made me aware of these risks and gave me the tools to act. In six months, my biological age went from +5 to -2.

Frequently asked questions
Questions about how it works, what we analyse, and what you'll receive.
At Synapse, we don't look at individual blood values in isolation — we examine how different values relate to each other. This means we can generate a wealth of insights from even a basic panel. More comprehensive lab sets give us even more to work with: the more data we have, the more accurate our predictions.
Preferably yes, but it's not strictly necessary. The more recent your blood test, the more accurately our results will reflect your current health. That said, we can also work with older tests. We recommend a blood test less than 3 months old.
Your biological age reflects how fast your body is actually ageing — based on the risk factors in your blood and lifestyle. Unlike your calendar age, it can change. Synapse uses it to show you where you stand today and how much room you have to improve.
Yes, all blood test formats are accepted. If we don't have enough information to make reliable assessments, those scores will be shown as unavailable with details on which biomarkers are missing.
