Aging causes what I call 'chronic jet lag syndrome'
It's a perma debuff that reduces the amplitude in circadian hormones, sleep duration, deep sleep and recovery.
Ultimately, you start aging much more rapidly after this happens
Here's a thread to postpone this⬇️⬇️
With age, the body's circadian rhythms go through many changes:
- dampening of circadian hormones like melatonin and cortisol (less fluctuations)
- reduced circadian signaling through the eyes and brain
- shorter sleep and more fragmented sleep
= NOT GOOD

The oldest man in history
Jiroemon Kimura is a Japanese man who holds the record for the longest lifespan in males (116 years, 54 days)
He lived throughout 3 centuries (1897-2013) and was the last pre-20th century-born man
Here are some amazing insights from his story⬇️⬇️
Jiroemon was born into a family in a fishing village and worked as a farmer until the age of 90
He had good longevity genes
His youngest brother lived to 100 and four of his other siblings made it past 90

Magnesium is the one supplement almost all doctors and longevity experts recommend
Why? Because it's the master mineral involved in hundreds of processes
And about 50% of people don't meet the recommended daily intake
Here's all you need to know about magnesium⬇️⬇️
Magnesium is the master mineral that's needed for countless essential processes in the body
- energy (ATP) production
- DNA repair
- neurotransmitters
- glucose regulation
- electrolyte balance
- heart function
- endothelial function
- blood pressure
And much more⬇️⬇️

The most jacked out of your mind 70-year old Polish man Wojciech Węcławowicz
He transformed his body in his 60s to a physique that puts most 20-year-olds to shame
Probably with the help of TRT but goes to show what's possible in your 70s⬇️⬇️
Wojciech isn't just about looks - he also maintains an impressive level of athleticism
He competed in the Polish Ninja Warrior
And won the silver medal in Pentathlon at the Masters World Championships in 2019

Exercise is known to be good for us, but how much exercise and is there something like too much exercise?
Exercise is often seen to have a J-shaped curve with mortality risk - not enough is bad but too much is also harmful (PMID: 32848273)
How much is optimal then?⬇️⬇️
The guidelines recommend adults get 150-300 min/week of moderate exercise or 75-150 min/week of vigorous exercise
Meeting that vs not is linked to a 36% lower odds of being overweight and 48% lower odds of being obese (PMID: 37773071)
However, exercising more than that is linked to a reduced risk of mortality

How to be healthier than 90% of people: 1. Stop alcohol/smoking 2. Exercise 3x a week 3. Don't drink sugar-sweetened beverages 4. Eat 80% whole foods 5. Sleep 7-8 hours
These are the fundamentals that most of the population doesn't meet, but there's more to optimize⬇️⬇️
How to be healthier than 95% of people: 1. Blood panel for the basic markers once a year and improve them 2. Weights 3x a week, cardio 2x a week 3. Regular bedtime and wake-up time 4. Eat higher protein (1.6 g/kg/day) 5. Time for relaxation
Want to get to the 1%?⬇️⬇️

Two markers everyone should test at least once in their life:
1. APOE gene - biggest genetic risk factor for Alzheimer's
- without counting calories
- without restricting any food group
- without working out for hours
- without feeling hungry or deprived
Here are the main ways I do it⬇️⬇️:
First off, obesity is one of the worst things for your health
It increases the risk of all chronic diseases and shortens your life expectancy by 10-20 years
Metabolically healthy obesity is a misnomer with metabolic syndrome increasing with BMI (PMID: 37237531)

Blood flow restriction training is epic
It's been found to trigger muscle hypertrophy response at only 20-30% of one rep max, whereas regular weightlifting usually is 70-80%
You basically trick your body into thinking you're lifting heavier than you really are
PMID: 26463594
Blood flow restriction training can:
- promote muscle growth
- accelerate recovery from injuries
- alleviate age-related muscle loss
- minimizes injury risk
- improve tendon structure and stiffness
- grow new blood vessels

Glutathione is often called the master antioxidant, but it’s actually regulated by melatonin (PMID: 20868358)
Besides sleep, melatonin also regulates inflammation, immunity, antioxidant activity, and autophagy the process of cell recycling
Melatonin co-ordinates vital rejuvenation processes in your sleep:
- the largest surge in growth hormone during the 24h cycle
- increased mitochondrial SOD (powerful antioxidant)
- NAD recycling through sirtuins
- autophagy and clearance of cell debris
- DNA repair

Just did a comprehensive 181 bloodmarker test at my retreat in a longevity clinic
Everything was great, except a bit high cortisol from jet lag and low T3 from recent lower calorie intake
Here are some of the most important markers:
Glucose panel

Glycine + NAC (GlyNAC) supplementation shows promise for longevity and increased healthspan
The only supplement that's repeatedly shown to reverse hallmarks of aging in humans
PMID: 35975308
A 2023 randomized clinical trial found that supplementing GlyNAC for 16 weeks in older adults improved glutathione deficiency, oxidative stress, mitochondrial dysfunction, inflammation, physical function, and 7 hallmarks of aging (PMID: 35975308)

Chronically high phosphate intake nukes your kidneys and promotes vascular calcification
- faster decline in kidney function
- heart disease
- higher risk of mortality
In both healthy people and kidney disease patients
link.springer.com/article/10.100…
Higher phosphorus intake is associated with an increased risk of cardiovascular disease mortality even among people with normal kidney function
Glycine has a lot of longevity benefits 1. Mimics methionine restriction 2. Increases autophagy and glutathione 4. Collagen synthesis 5. Inhibits advanced glycation end-products (AGEs) 6. Lowers blood sugar 7. Promotes good sleep quality
PMID: 37004845
Glycine is considered a non-essential amino acid because the body can synthesize it
However, the body makes only 3 grams a day, which is not enough for optimal collagen turnover and other vital functions

Magnesium is the master mineral
A deficiency in magnesium can secretly undermine your overall health
Yet, about 50% of people don't meet the RDA for magnesium
Magnesium activates ATP, which is essential for energy production and cell function
ATP is required for heart muscle contraction and life overall

Loss of autophagy is one of the hallmarks of aging
Autophagy is also central to the other hallmarks of aging
Autophagy is the process of recycling old and dysfunctional cell components
PMID: 34563704
Aging and age-related diseases decrease autophagic activity and promote its dysfunction (PMID: 31144030)
Reduced cellular recycling and accumulation of waste inside the cells are common to all aged cells (PMID: 16874025)

NAD depletion promotes many age-related diseases
Aging is a common reason for declining NAD levels, but it's not the root cause
Here's a thread on the things that deplete your NAD pool⬇️⬇️
PMID: 33609766
CD38 is the main consumer of NAD and the primary reason NAD declines with age
CD38 is a glycoprotein that rises during inflammation
CD38 levels increase 2-3-fold during aging, which is paralleled by a decrease in NAD
PMID: 27304511

Low NAD is at the core of all the hallmarks of aging
NAD levels appear to decline with age and this promotes all the other hallmarks of aging
However, there's one critical mistake almost everyone makes when boosting NAD
(PMID: 32097708; DOI:10.1016/j.tma.2018.08.003)
The salvage pathway is the main source of your body’s NAD and it recycles NAD and its precursors
NAMPT is the rate-limiting step of the salvage pathway
NAMPT creates NMN from nicotinamide, which then gets converted into NAD

Epic pre-workout stack: 1. Sodium (1,000-2,000mg with 8oz water) 2. Citrulline (5g) 3. Creatine (3g) 4. Caffeine (100mg) 5. Glycine (3g)
As a bonus, if your goal is tendon and bone density then a 30g collagen dose might be more effective than 15g
