The scientific approach to health, performance and longevity

Research on entrepreneurship shows that successful innovations are made by people who are actively shaping the future, instead of waiting for the future to occur. So why should we wait for severe symptoms of diseases to show up before we start taking care of our health?

Let’s go one step further in our business metaphor: it’s way too risky to build a product without testing your assumptions, gathering data, and iterating. So why should we approach our health with guesswork and generic advice? Isn’t your own health the most important “product” you are working on? In this article, I’ll explain my proactive approach to health.

If there's one thing I’ve learned from years of working with agile approaches like Build-Measure-Learn (Lean Startup) or Plan-Do-Check-Act (Deming-Cycle) or iterating in sprints (Scrum), it’s this: In uncertain and complex environments, a scientific approach („Hypothesis-Experiment-Iterate“) is key! And what’s more complex than your health?

Health is an experiment – so treat it like one

Human metabolism is a vast, adaptive system. Take Magnesium, for example: it's involved in over 300 enzymatic processes. If your body is running low, it won’t just shut down; it will prioritize. My body might prioritize differently than yours, based on genetics, lifestyle, and the current situation.

This is why symptoms alone rarely tell the whole story. Fatigue, brain fog, or muscle cramps could mean a Magnesium deficiency — or not. Maybe another bottleneck, like low Sodium, could cause the cramps.

Instead of blindly supplementing, I follow an iterative approach:

  1. Measure – Test blood markers to identify potential deficiencies.
  2. Analyze – Use data to make informed decisions on supplementation or diet changes.
  3. Adjust – Implement changes, then re-measure after a set period.

Just like in agile product development, it’s all about small, controlled experiments instead of reckless trial and error.

If you are curious to dig deeper into the N=1 experimentation topic, this article by Nick Norwitz could be an inspiring next step: Paving the path for n=1 citizen science.

The foundation: essential vs. semi-essential micronutrients

When optimizing health, I focus on essential and semi-essential micronutrients:

  • Essential micronutrients – The body can’t produce them, so we must get them from food or supplements. These include vitamins, (trace) minerals, amino acids, and fatty acids (e.g., EPA and DHA Omega-3s).
  • Semi-essential micronutrients – The body can produce these, but often not in sufficient amounts (especially under stress or aging).

My hypothesis on (semi-) essential micronutrients

If I ensure optimal levels of all essential and semi-essential micronutrients, my body has the best possible foundation to handle stress, infections, and daily performance demands.

From my point of view, a proactive approach like this is way better than just reacting to symptoms, which might only appear when the body has already been compensating for too long.

Why generic advice can be risky

You've probably heard statements like: "Take L-tyrosine to boost dopamine for motivation!" Sounds good, right? But here’s the problem:

Dopamine synthesis doesn’t just depend on Phenylalanine or Tyrosine. It also requires cofactors like Vitamin B6, Iron, and Copper. If any of these are missing, extra Phenylalanine or Tyrosine won’t help with your motivation. (Remark: this could be one reason why studies or experience reports sometimes show that one substance is not effective.)

Or consider Vitamin D: If you assume you're deficient and take high doses without testing, you might overshoot and cause calcium imbalances, leading to kidney stones or arterial calcification or decrease of bone density. That’s why I always measure before and after making changes.

Strategic supplementation: anticipate, don’t just react

While measuring is crucial, some situations call for proactive adjustments:

  • Performance optimization – If I'm preparing for an endurance event, I do not wait for my next blood work to be sure that I am running out of electrolytes, I increase my minerals' intake in advance.
  • Lifestyle factors – If I know I’m getting little sun exposure, I monitor vitamin D levels more closely.
  • Drug interactions – Some medications deplete nutrients (e.g., statins lower CoQ10, birth control pills affect B vitamins). If I had to take medication long-term, I would factor this into my health plan.

This isn’t about blindly taking supplements — it’s about strategic precision.

Final takeaway: health, the agile way

  • If you care about performance and longevity, stop relying on generic health advice. Instead, approach your body the way you'd approach building a high-performance system:
  • Test, don’t guess – Data beats assumptions.
  • Measure and iterate – Small adjustments, tested over time, lead to better results.
  • Think holistically – Deficiencies and imbalances are often interconnected.

Because just like in business, what you don’t measure, you can’t improve. And maybe it’s a good idea to ask someone with expertise and experience to accompany and coach you on your first steps.

Founder interview: Dr. Emil Kendziorra, Founder & CEO at Tomorrow Biostasis

In our Founder Interview series, we highlight the brightest minds in preventive health, wellness, and longevity. In Episode 6, we’re honored to feature Dr. Emil Kenziorra, founder and CEO at Tomorrow Biostasis—one of the world-leading human cryopreservation experts.Tell us a little about yourself and your current ventureDoctor and researcher by training, entrepreneur by trade. Longevity has always been my motivation, with a focus on maximal life span extension. I'm running Tomorrow.bio and the non-profit European Biostasis Foundation to push human cryopreservation forward.How do you balance the demands of running a business while maintaining your own health and longevity?I've always worked a lot and my natural stress level is pretty low, plus good sleep and working out regularly. So all good :) Do you have a personal health goal? What is it? Not die - indefinitely, until I change my mind :)Before launching Tomorrow Biostasis, can you walk us through the “aha” moment that inspired the creation of your service?I've been involved in the longevity space in same capacity since 2007. I took a deep dive again in 2019 and after selling my last company in 2020, I switch to cryopreservation. There just isn't any meaningful progress in the field, with the billions of spending and decades of research maximum life span has not been extended by even a day. What sets Tomorrow Bio apart in the health and wellness industry?Accepting that maximal life span extension is not likely if we look at progress so far. If someone wants to live longer than currently possible, cryopreservation will be a necessary stopgap measure.What is the most groundbreaking or unexpected finding in the field of longevity research that you’ve come across recently, and why do you find it so compelling?Nothing really. The next big milestone will be a clinical trial that shows extension of maximal life span.  In your opinion, which emerging longevity trend or product will have the most transformative impact on our health over the next five years, and why?Gym, sleep, healthy food - rest is noise for now.One thing you wish more people knew about health and longevity?It's the most important thing in the world.What is the biggest longevity myth you’d like to debunk?Any thing that is available right now is proven to extend maximal life span. If you could recommend only one supplement for a longer, healthier life, which would it be, and what makes it indispensable?Vitamin D, most people have deficiencies. How old can we potentially become at maximum?No limit in theory. At least I'm not aware of any. What resources (books, podcasts, mentors) have been most valuable in your entrepreneurial journey?https://waitbutwhy.com/If there’s one message or insight you’d like readers to take away from your journey, what would it be?Work in Longevity!

Vitamin K for cognition

Vitamin for the mind. Could a simple vitamin found in leafy greens keep your brain sharp with age? New research from Tufts University hints that vitamin K deficiency might speed up mental decline—especially in memory and learning.Key facts & findingsBrain booster: Vitamin K shows up in brain tissue as menaquinone-4, potentially supporting cognitive function.Less K, more problems: Mice lacking vitamin K displayed worse results in tests assessing memory and spatial learning.Hippocampus hit: The vitamin K–deficient group had fewer new neurons in the dentate gyrus, a key region for learning.Inflammation spike: These deficient mice also showed overactive immune cells (microglia), leading to higher brain inflammation.Additional context & expert insightVitamin K is typically found in dark, leafy veggies—like spinach and kale—and is already known for aiding blood clotting. This study suggests it might also protect the aging brain by boosting neuron formation and reducing inflammation. “We’re not telling everyone to go buy supplements,” says the research team, who stress that a balanced diet is the real key. Put differently: your daily salad might do more than keep your arteries clear—it may also keep your mind in top form.Looking aheadScientists plan to dig deeper into the exact mechanisms tying vitamin K to brain health, and possibly see if the same trends hold in humans of all ages. For now, consider upping your veggie intake. Your brain, and maybe your future self, will thank you.

From bloodwork to DNA to AI and back: my journey to solve a micronutrient mystery

How low zinc levels turned into a detective story about health optimization, genetics — and how to use ChatGPT wisely without falling into traps.Hi, I’m Heiko – coach, biohacker, and micronutrient enthusiast. For years, I’ve been fine-tuning my approach to health and longevity by regularly testing my blood for micronutrient levels. Why? Because I believe that keeping all essential and semi-essential micronutrients in the optimal range gives my body the best possible foundation to thrive — mentally, physically, and emotionally.It’s a proactive strategy inspired by experts like Dr. Helena Orfanos-Boeckel, and it’s shaped how I think about performance, stress resilience, and long-term health.One nutrient I’ve been particularly focused on is zinc. And yet — despite consistent, even high-dose supplementation — my blood levels of zinc just won’t budge into the optimal range. Frustrating? Definitely. But also a great opportunity to dig deeper.That’s how this article came about. After a nudge from Sandra (thanks again!) in the New Zapiens community, I decided to revisit my DNA test from SelfDecode. Maybe the answer to my stubbornly low zinc levels was hiding in my genes?Why is zinc so important?Before we dive into the analysis, let’s take a quick detour: zinc is a true multitasker.It plays a key role in the immune system, supports wound healing, and helps fight infections.It’s essential for protein synthesis, making it crucial for muscle growth and recovery.It influences cognitive function, impacting focus and mood.It acts as a cofactor for many enzymes, involved in metabolism, hormone production, and digestion.And here’s a kicker: If you exercise a lot or sweat frequently (sauna, anyone?), you could be losing significant amounts of zinc.Sounds like something you’d want enough of, right? That’s exactly what I thought — but my levels refused to rise ...Checking my DNA test: no red flags?My first glance at my SelfDecode report:SelfDecode resultSo, no increased requirement according to my genetic data. Hmm.But maybe ChatGPT knows more?I asked whether there are SNPs associated with higher zinc needs.(SNPs = Single Nucleotide Polymorphisms, genetic variations that can influence various bodily processes.)ChatGPT provided a first list of potentially relevant SNPs:Screenshot 2025-04-10 175904.png 176.05 KBNever only ask once, especially with ChatGPT ;) So I asked again if there might be some more SNPs that could be relevant. And ChatGPT listed some more:Screenshot 2025-04-10 180441.png 224.03 KBBased on that, I dug into my SelfDecode data and checked my own genetic variations. And I added all the SNP characteristics that SelfDecode had listed as relevant, even if the overall assessment did not reveal an increased need.Then, I asked ChatGPT to interpret all my individual data.Screenshot 2025-04-10 181041.png 59.84 KBThen I asked ChatGPT to critically review its own assessment.Screenshot 2025-04-10 181228.png 17.69 KBSurprise, surprise: ChatGPT’s analysis and conclusion was quite different from SelfDecode’s!While SelfDecode suggested my zinc needs were typical, some SNPs flagged by ChatGPT pointed to a significantly increased requirement!And then I remembered a phrase from the domain of management theory and practice: Culture Eats Strategy for Breakfast.And I asked myself: What if “Lifestyle Eats Genetics for Breakfast”? So what about exercise and sauna for example?I added details about my workout and sauna routine and asked for an updated recommendation.Screenshot 2025-04-10 181433.png 99.79 KBDone? Hmm… not so fast!The trap of question framingAnother shoutout to Sandra, who reminded me that answers by AI models like ChatGPT are highly dependent on how you phrase your questions.So, I reworded the question: Could it be that the original recommendation was way too low in comparison to standard recommendations?Screenshot 2025-04-10 181633.png 148.02 KBThen, I went the opposite way: Was the updated recommendation too high? Maybe ChatGPT simply added up all effects, without considering overlapping factors?Screenshot 2025-04-10 181807.png 157.65 KBNow I had multiple versions of an answer. Which one should I trust?Guess what I did … of course: I asked ChatGPT: “So, first too low, then too high, now low again, ... what can I believe you?” ;)Screenshot 2025-04-10 181946.png 236.65 KBAnd: Screenshot 2025-04-10 182334.png 62.61 KBI totally agree: blood work is not the truth, but the best approach we have!Conclusion: ChatGPT is a great tool — if you know how to ask and how to interpret and challenge its answers Please keep in mind: Everybody and every body is different.My unique lifestyle, diet, and habits can’t (yet) be fully captured by any AI model.And that’s fine with me. I now have enough information to fine-tune my zinc supplementation approach. Taking also my individual experiences and some hints by Chris Masterjohn into account, I will supplement like this:👉 2×15 mg zinc citrate in the early morning👉 25 mg zinc bisglycinate in the later morningTwo highly bioavailable forms, taken as far away as possible from other minerals (esp. copper) that could block absorption or interact directly.Now, it’s all about testing, measuring, and adjusting again.Will my zinc levels finally move? Or are there other aspects that I don’t know yet?To be continued... 😃
