Green tea is one of the healthiest beverages in the world
- improves cardiovascular disease risk factors
- improves heart health
- improves metabolic health markers
- targets all hallmarks of aging
- reduces visceral fat
- is associated with lower mortality

Green tea contains many bioactive compounds that target all the hallmarks of aging:
- genomic instability
- telomere attrition
- epigenetic alterations
- loss of proteostasis
- impaired autophagy
- deregulated nutrient sensing
- mitochondrial dysfunction
- cellular senescence
- stem cell exhaustion
- altered intracellular communication
- chronic inflammation
- gut dysbiosis
Most of these effects are mediated by EGCG and other polyphenolic compounds in green tea

A 2023 meta-analysis of 55 randomized controlled trials saw that green tea supplementation:
- lowers total cholesterol
- lowers LDL cholesterol
- raises HDL cholesterol
- lowers fasting blood sugar
- lowers HbA1c, a marker of long-term glucose levels
- lowers blood pressure
Ice baths are a very popular trend on social media
So are saunas but to a slightly lesser degree
But which one has more health benefits?⬇️⬇️
Sauna has many protective health benefits and appears to even offset the higher risk of all-cause mortality related to lower socioeconomic status, high blood pressure, and high inflammation levels
PMID: 37270272
Using the sauna >4x a week compared to 2-3x is associated with:
- 63% reduced heart disease mortality
- 50% lower fatal cardiovascular disease
- 46% lower risk of hypertension
- 40% reduced all-cause mortality
I analyzed Bryan Johnson’s biomarkers… and he doesn’t have the best in the world.
I analyzed 65 of the markers he’s published:
-44 of them I have better results
-9 of them, Bryan has better results
-12 of them are equal
In this thread, I’m sharing the markers and comparing them⬇️⬇️
P.S.
1. I’m not claiming I'm the healthiest person alive or to have the world’s best biomarkers—but I do have factually better biomarkers than Bryan.
There are dozens of people who have better biomarkers than Bryan and me out there.
2. This isn’t about “dunking” on Bryan. Bryan always asks for people to challenge his results and prove if someone has better markers, so here I am.
3. I disagree that you can base someone's health solely on biomarkers because biomarkers can be gamed with pharmaceuticals, etc. But I'm just playing Bryan's own game here.
4. Age is a moot point. Bryan says he has the best biomarkers of anyone in the world. If chronological age mattered, the “healthiest person” would always be an 18–20-year-old.
I’m 30, and my biomarkers are better than his, so his claim doesn’t hold. He could argue he’s the healthiest 47-year-old, but not the healthiest overall.
Now that this is out of the way, let's go through all the biomarkers.
Quick summary of the differences in our biomarkers:
-Bryan has good metabolic health, but I have slightly better
-Bryan has poor kidney function – mine is excellent
-We have semi-equal liver values and lipids
-Bryan’s fitness (strength/VO2) is good for his age, but not elite by any means. Mine is significantly better
-We both have normal hormone levels, nothing extraordinary
-Bryan’s PhenoAge (biological age) based on his biomarkers is 8.81 years lower than his chronological age, mine is 18.5 years lower
Fitness markers
VO2 max
- Bryan 54.2 (good but not elite)
- Siim 66 ✅
Grip strength
- Bryan 132 lbs (I don’t know if it’s combined arms or one arm)
- Siim 150 lbs ✅(combined arms 298 lbs)
Bench press
- Bryan 240 lbs
- Siim 300 lbs ✅
Leg press (the quarter-depth leg press test)
- Bryan 850 lbs (barbell parallel squat probably around 115 kg based on leg press result)
- Siim 1,000 lbs ✅(barbell parallel squat 160 kg)
Middle-aged and older athletes, especially those who exercise for over 2000 MET-min/week, have significantly higher coronary artery calcification scores than controls (PMID: 28465287; PMID: 28450347)
People with a higher VO2 max and better cardiorespiratory fitness still have lower rates of cardiovascular disease events across all levels of calcification (PMID: 29343464)
Those with a VO2 max over >50 see attenuation in risk compared to those with a VO2 max of <45
