Hi, I'm Karol.

I am building a global longevity tribe to help people find the most trusted wellness and longevity brands to extend their healthspan and lifespan: www.newzapiens.com

–––

Healthcare is broken.

Doctors and pharma companies profit from treating illness, not keeping us healthy. The wellness industry is full of bold claims with little to no evidence. Health gurus and influencers capitalize on our insecurities, offering questionable advice that often misleads rather than helps.

In a world where trust is everything, who can we rely on?

In July 2023, New Zapiens started as a private WhatsApp group. Karol and Simon, two fathers, shared reliable health and longevity tips, aiming to extend their health spans and maximize life’s potential.

This conversation quickly grew into a global community of thousands health enthusiasts. They uncovered a common issue: most people struggle to find the time and trustworthy information needed to make confident health decisions.

As a result, New Zapiens evolved into a trusted platform for wellness, health, and longevity. Here, people discover reliable brands and products, reviewed by real individuals who have tested them without bias.

Our mission: Building a trusted health hub that empowers everyone to make better decisions through reliable, authentic, and honest reviews.

For brands committed to transparency, New Zapiens offers genuine feedback and the opportunity to collaborate with a loyal, health-focused community to build top-quality products.

Most health content is recycled garbage written by marketers who've never treated a patient.

We're building something different with New Zapiens: 
a platform where actual practitioners share what works.

Over the past year, we've published 100+ articles from MIT neuroscientists, Harvard-trained physicians, and Stanford researchers, reaching millions of health optimizers who actually implement this stuff.

Now we're expanding our contributor network.

If you're working in: 
∙ Longevity medicine 
∙ Performance optimization 
∙ Metabolic health 
∙ Sleep & recovery science 
∙ Preventive healthcare 
∙ Evidence-based nutrition

Here's what we offer:
→ Platform with tens of thousands of engaged readers 
(68% founders/C-level executives)
→ Newsletter distribution (60% open rate, 10% CTR)
→ Full backlinks and attribution
→ Social amplification across our channels

What we're not looking for: 
• Promotional content
• Sales pitches
• Recycled listicles

What we are looking for: 
Practitioners who can translate complex science into actionable insights for busy, high-performing health optimizers.

Past contributors include: 
∙ Dr. Teresa Cramer (MIT neuroscientist) 
∙ Dr. Anne Latz (Harvard-trained) 
∙ Dr. Hillary Lin (Stanford physician) 
∙ Dr. Paul Hammer (microbiome specialist) 
∙ Dr. Dominik Duscher (Stanford-trained peptide researcher)

The bar is high. 
The audience is sophisticated. 
The impact is real.

Let's make evidence-based health optimization accessible to more people who'll actually use it.

Health brands are making millions off your fear of death. 

And the founders are pretending it's "preventive care".

I meet more and more people who refuse to get tested for cancer, heart disease, or genetic conditions.

Not because they can't afford it. Because they'd rather not know.

They tell me they're more afraid of the diagnosis than the disease itself. They'd rather live in uncertainty than face a positive test result.

And I completely get why. Working in preventive health means I think about death more than most people.

And honestly? I'm watching something that makes me sick.

The longevity industry has turned fear into a business model.

Brands are using your terror of death to sell you protocols you don't need. 
They're weaponizing mortality to drive conversions.

↳ "Test now or regret it later" 
↳ "Your genes are a ticking time bomb" 
↳ "Every day you wait, you're closer to the end"

This isn't health optimization. It's fear mongering.

Being afraid of a bad diagnosis is completely normal. Human, even.

Choosing not to test for something is a personal decision. Your body, your choice, your timeline.

But using people's deepest fears to generate revenue?

That's a red flag.

The best health brands I work with do the opposite. They remove fear from the equation. They focus on empowerment, not anxiety. They make testing feel like gaining control, not losing it.

Fear might sell in the short term. But it destroys trust in the long run.

If you're building in health, ask yourself: Are you helping people face their fears, or are you exploiting them?

When Dr. Bastian Mayerhofer reached out and asked if I wanted "full fasting benefits while eating," my BS radar turned red. [Ad]

I've been experimenting with fasting for years. Water fasts, 16:8, OMAD (one meal a day).

Same wall: Day 3 of a water fast? I'm obsessing about food. Headaches. My energy crashes. Doesn't fit my work-family lifestyle. 

Then Bastian shared a GeroScience trial: Fasting-Mimicking Diets (FMD) trigger autophagy, measured in human blood cells, while improving insulin resistance, glucose, and ketones.

After digging into it, I decided to test ProLon’s 5-Day Next-Gen Box.

Why fasting matters:

When you fast, your body switches from growth mode to repair mode. It triggers autophagy, your cells' cleanup system that recycles damaged parts. Think of it as taking out the cellular trash.

This targets multiple hallmarks of aging:
↳ Cellular senescence
↳ Mitochondrial dysfunction 
↳ Inflammation

The problem? Water fasts burn muscle with fat. Most people quit.

The key difference with FMD is that it preserves lean muscle mass while targeting fat loss.

Translation: Your cells clean house. You keep your muscle.

Here are my results after ProLon's Next Gen Fasting Box, a 5-day FMD program.

What's in it:
↳ 5 days of plant-based soups, bars, snacks, teas
↳ ~1,100 kcal day 1, ~700-800 kcal days 2-5
↳ Low protein, low sugar, high healthy fats
↳ All soups and teas are organic

What I measured:
↳ Lost 2.1 kg total weight
↳ Lost ~400g visceral fat (dangerous fat around organs)
↳ Lean muscle mass conserved (<0.5 kg lost)
↳ Ketones hit 1.4 mmol/L by day 4
↳ Morning glucose dropped to 78 mg/dL
↳ Resting heart rate down 5 bpm by day 5
↳ Energy stayed stable, focus got sharper each day

My honest rating:

Taste ●●●●○
I expected the worst but was surprised. The soups were actually good, bars tasty, crackers and olives great.

Convenience ●●●●●
You get 5 boxes. Just eat. Heat up soups. That's it. Could even do this while traveling.

Energy ●●●●●
I had little to no hunger. Ate good food and got all fasting benefits. Felt sharper with each day and still worked out lightly. 

Evidence ●●●●●
ProLon has 32 human studies in top journals. This is tasty, effective science. (sources in comments)

Price ●●●●○
€249 is real money. But high-quality organic meals, convenience, and taste make it worth it. There’s also a non-organic option for €189.

Overall:
4.6 out of 5 stars

Who is this for?

Busy professionals who want fasting benefits without losing muscle. People intimidated by water fasts. Anyone who wants cellular repair while eating real food. Even if you love good food, like me.

My verdict:

I'm genuinely surprised. Didn't expect such a complete experience. Getting full fasting benefits is now doable, without muscle loss, starving, or suffering.

If you've been thinking about fasting and keep putting it off, this removes every excuse.
