Who We Are
We’re not here to sell you a miracle.
We’re here to remind you: real change starts inside.
At Key Proteins, we believe strong skin, resilient joints, and daily energy don’t come from filters or fads — they come from consistency, science, and taking care of what matters most: you.
This isn’t just collagen.
This is your daily signal to show up — for your body, your confidence, your life.
One scoop. Every day. That’s the key.
Leading the future of collagen.
At Key Proteins, innovation meets intention. Our collagen peptides are carefully hydrolyzed to a golden molecular weight range of 500 to 2000 Daltons — clinically recognized as the sweet spot for optimal absorption and bioavailability.
Sourced from the purest deep-sea fish and grass-fed bovine, each scoop delivers clean, high-performance nutrition that your body can actually use. No fillers. No fluff. Just the key components your skin, joints, and muscles crave — delivered with precision, purity, and purpose.
We don’t follow collagen trends.
We set the standard.
Pure Marine Collagen
Sustainably sourced from deep-sea fish, marine collagen is rich in Type I collagen — known to support skin elasticity, hydration, and youthful glow from within.
Optimized Absorption.
Our peptides are hydrolyzed to an ideal molecular weight of 500–2000 Daltons — the clinically recommended range for faster absorption and better body utilization.
Grass-Fed Collagen
Derived from pasture-raised bovine, this source is rich in Types I & III collagen — essential for supporting joint flexibility, bone strength, and muscle recovery.
Our Story
Key Proteins | Leading the Future of Collagen
In an era where wellness products fill the shelves and social media feeds overflow with miracle claims, Key Proteins was born out of a different vision—a vision rooted in integrity, science, and real human needs.
For years, collagen supplements have grown in popularity, yet the industry has been clouded by vague promises, misleading labels, and a lack of real innovation. Consumers were offered “collagen” without knowing its source, molecular structure, or actual bioavailability. Many products were built on buzzwords—not on biology.
At Key Proteins, we saw the gap—and we stepped in to close it.
Our mission is clear: to deliver the most effective, clean, and trustworthy collagen peptides on the market, empowering people to look, feel, and live their best.
The Problem We Saw
As more people turned to collagen for beauty, mobility, and wellness, we noticed three major industry problems:
Molecular Weight Confusion
Many collagen products contain large, hard-to-absorb molecules. Consumers didn’t know that molecular size dramatically affects absorption. What good is collagen if your body can’t use it?Unclear Ingredient Origins
Brands rarely disclose whether their collagen comes from healthy animals or safe environments. Deep-sea fish and grass-fed cattle are vastly different from farmed alternatives—but most labels don’t tell you that.Lack of Formulation Precision
While science shows that collagen peptides between 500 Da to 2000 Da are optimal for absorption and effectiveness, most products don’t specify, or worse, contain a wide, ineffective range.
We believe people deserve better.
Why We Exist
Key Proteins was founded with a singular focus: to create collagen products that actually work, with nothing to hide.
We source only from clean, traceable origins—wild deep-sea fish and pasture-raised, grass-fed bovine—ensuring both purity and ethical standards. Our collagen peptides are meticulously hydrolyzed to reach a precise molecular range of 500 Da to 2000 Da, allowing for optimal absorption into skin, joints, bones, and hair.
We don’t chase trends.
We pursue results—backed by science and refined by experience.
And we don’t believe in dressing up what doesn’t need it.
While others invest heavily in glass jars, metallic tins, or influencer-driven packaging, we take a different path. Our products come in light-resistant, high-barrier aluminum foil pouches—not for aesthetic minimalism, but for practicality, sustainability, and purity protection.
Every cent saved from unnecessary packaging goes directly into what matters most: better raw materials, more effective processing, and higher collagen purity.
Because beauty doesn’t come from a box—it comes from what’s inside.
