About
Andrei Alencar

Most men's health sites are run by people who only read about health. I'm a registered nutritionist who has worked in the field for over twenty years — and I test these protocols on myself before I write a word about them.

I graduated in Nutrition from Universidade do Sagrado Coração (USC) in Bauru, Brazil, in 2002, and I'm registered with the Regional Council of Nutritionists (CRN-3, São Paulo), license 11887. My career has been in large-scale, institutional nutrition — feeding people at scale, where getting the fundamentals right matters more than any trend.

I'm also a Brazilian jiu-jitsu black belt. I earned it in 2010 the hard way — by competing my way up. In 2008 I won a Brazilian Masters national title (CBJJ) as a purple belt. At 49, I still train five days a week.

Why This Site Exists

For years my body absorbed everything I threw at it — bad sleep, relentless stress, food on the run, training done half-right. Then, just after 40, the bill came due: a tiredness coffee couldn't fix, recovery that dragged, mood that swung, the strange feeling of working twice as hard for half the results I used to get.

The turning point was looking in the mirror and realizing that if I kept going, the second half of my life would be a slow decline instead of my best years. So I did what a nutritionist should: I went to the research, tested it on myself, and learned the actual physiology of the 40-plus male body.

When I got my energy, drive, and strength back — performing better today than I did at 30 — it stopped being personal and became a mission. Too many men over 40 suffer in silence, taught to blame age and swallow it. They don't need hype. They need practical, honest, evidence-based answers to take back control of their own biology. That's what Alpha40Fit is.

What I Write About

Testosterone and male hormonal health — natural approaches first, with honest context on the medical ones. Energy and the cellular machinery behind it. Resistance training for men 40+. And supplement analysis — ingredient by ingredient, dose by dose.

How I Review a Supplement

I read every formula the way I'd read a lab report — ingredient by ingredient, not by the label's marketing.

• Dose vs. evidence: I compare each ingredient's amount to the dose actually used in the studies. A "clinically studied" ingredient at a fraction of that dose is just a label claim.
• Form & absorption: magnesium glycinate isn't oxide; ubiquinol isn't ubiquinone. I flag forms chosen for cost over uptake.
• Evidence quality: human randomized trials outweigh animal and test-tube data. When the evidence is thin or early, I say so.
• Proprietary blends: if a label hides doses inside a "blend," that's a red flag, not a feature.
• Honest verdict: I point out what's underdosed even in products I recommend — and an affiliate link never changes the verdict.

Who This Is For

I write in English for men — especially in the United States — who are over 40, still working and ambitious, and unwilling to accept decline as inevitable. I'm based in Brazil; the physiology is universal.
