The Heart Behind the Brand
When I started K3 Nutriments, it was born out of decades of obsession...my obsession with wellness, longevity, performance, and integrity. I was a competitive bodybuilder, sure, but more than that, I was—and still am—a student of the human body. Thousands of hours buried in research journals, countless experiments on myself, and a commitment to understanding health from the inside out shaped what this company is today.
But something shifted a couple of years ago.
It was my daughter Lena who looked at me one afternoon—half-joking, half-challenging—and said, “Dad, why do you know so much about keeping the inside of your body young, but you’re not doing anything for your skin?”
She had a point.
Where Science Meets Skin
That question stuck with me. I had always focused on internal health—mitochondrial efficiency, inflammation reduction, metabolic performance. But skin? Our largest organ? The first thing people see and, perhaps more importantly, our outer barrier of defense?
I hadn’t given it the respect it deserved.
So I dove in. I approached skin the same way I approached building muscle or formulating Keto Drops—relentlessly, systematically, scientifically. We consulted with formulators. We studied the literature. And I asked one question over and over again: What actually works?
This is how K3 Nutriments Skin Care was born.
Clean, Vegan, and Research-Driven
We don’t slap the word “clean” on a label for marketing. Every product in our skin care line is manufactured in the USA, in FDA-registered, GMP-compliant facilities. They’re vegan, cruelty-free, and formulated with integrity. And every ingredient serves a purpose.
Let me introduce you to our flagship formula:
Advanced Multi Peptide Cream
This cream is one of the products I’m most proud of. It’s a versatile, hydrating blend of six advanced peptides, hyaluronic acid, squalane, jojoba seed oil, and apricot kernel oil.
What It Does:
-Reduces the appearance of fine lines
-Plumps and hydrates the skin
-Promotes long-term firmness
-Delivers multi-layered moisture
I’ve personally used it every day for over a year. My skin feels smoother, firmer, and dare I say, healthier. It's what I now call performance skincare—for people who expect real results.
Lena's Influence and the Real Reason This Matters
Lena’s generation is growing up with more awareness around clean beauty, toxic load, and ingredient transparency than ever before. She told me, “I want something I can use that works—but I want to know where it comes from.” That hit me hard.
This is why I pushed so hard for clean formulations.
This is why I insisted that everything be vegan, free of synthetic fragrances, and rooted in science—not hype.
Explore the Full Line
Our skin care line isn't built around fads. It's built around efficacy.
Here are the other products we’ve developed:
Red Tea Moisturizing + Antioxidant Serum
Packed with hyaluronic acid and antioxidant-rich rooibos, this serum calms inflammation and restores radiance. I like to apply it before the Multi Peptide Cream for a double-layer hydration boost.
Face Exfoliator & Cleanser with Honey & Bamboo
Gentle enough for daily use, this cleanser uses natural bamboo stem extract to polish away dead skin and honey to soothe and protect. This one’s a Lena favorite—and it smells incredible.
Brightening Boost Exfoliator Pads
If your skin feels dull, these pads will be your go-to. Infused with AHA/BHA and botanical brighteners, they gently exfoliate while evening out skin tone and texture.
Firming Cucumber Eye Cream with Bakuchiol
This is our clean, plant-based alternative to retinol. Bakuchiol firms and smooths delicate under-eye skin—without the irritation. The cucumber extract adds a cooling, de-puffing effect that’s noticeable from the first use.
Skin Care That Works as Hard as You Do
If you’ve followed K3 Nutriments for a while, you know this: we never release a product unless it works. We’re not in the business of fluff or filler.
Our skin care line is for people who work hard, think deeply, train intentionally, and want to look as strong and healthy on the outside as they feel on the inside.
Because skin care isn't vanity. It’s health.
And like Lena reminded me—if we’re going to take care of every organ inside our body, why wouldn’t we take care of the one everyone sees?
Final Thoughts
From formulating weight loss aids like Keto Drops to longevity-focused supplements like Fermented Melatonin, our mission at K3 has always been the same: to help people live better, longer.
Expanding into skin care wasn’t a departure from that mission—it was a natural evolution of it.
This is skin care created with intention, backed by science, and driven by the people I love most.
