Head of Research & Innovation at Revi Health – a longevity, performance, and regenerative medicine clinic in Stockholm. Background in biomedical science, functional medicine, and advanced health optimization. I write Meta Medicine on Substack where I explore the intersection of health optimization and clinical medicine through an evidence-based, integrative perspective. Perpetually curious about what makes humans perform better and live longer. Coach, educator, researcher, and student of Life.

My Routines

Movement & training

Cardio and mobility in the morning Monday through Friday — a mix of zone 2, lactate threshold, and interval training (typically 4x4). Resistance training midday on Monday, Tuesday, Thursday, and Friday, following an upper/lower A/B split — basic progressive overload, nothing fancy. Wednesdays, Saturdays, and Sundays are active recovery — stretching, sauna, and long walks.

Diet & nutrition

After 20+ years of experimenting with everything from all-fruit to all-meat and everything in between, I've landed on a balanced, omnivorous whole-foods approach. Coming from a sports and fitness background, I keep a rough sense of caloric intake but don't count diligently. I also try to stop eating 3–4 hours before bed. Eating close to bed is the number 1 thing that affects my sleep quality, RHR, and HRV.

Supplements, medications & ancillaries

I take a lot of supplements — everything from the basics to more exotic and niche stuff — but I'm not going to list them all here. That said, I don't think most supplements yield more than maybe 3–5% on top of the basics, which is where the emphasis should be. Supplements add an extra layer of self-experimentation for me, and it's something I enjoy playing around with.

I'm also open about using certain medications and ancillaries as part of a proactive, longevity-oriented strategy — guided by bloodwork and under medical supervision. I think the line between "supplement" and "medication" is more cultural than scientific, and what matters is the risk:reward profile and the data behind it.

Sleep, recovery & relationships

I work a lot but protect my sleep and make sure to get 8 hours in bed every day. Weekends are mostly offline from work and training, spent with my girlfriend and our two cats. We travel roughly once a quarter, which is a nice reset from the fast pace and routine of everyday life. When traveling, I keep things simple — sensible eating, basic supplements like a multivitamin, magnesium, and omega-3, and no tracking.

Health monitoring & proactive screening

Comprehensive bloodwork on a quarterly basis, complemented by other health screenings including colonoscopy, CT, DEXA, MRI, VO2 max testing, and whole genome sequencing. I also do periodic deep-dives with nutritional testing, stool analysis, organic acids testing, and screening for environmental pollutants, heavy metals, microplastics, and other toxins through my previous company GetTested. I'm a proponent of aggressive and proactive health screening — as long as it provides value.
