About Flexcin
For over two decades, Flexcin has been trusted by thousands who want to stay active and comfortable—without relying on pharmaceuticals. Our proprietary ingredient, CM8, is the heart of our formulations, earning loyal customers year after year in both humans and pets.
But our story didn’t stop there.
“I saw firsthand how joint issues impact quality of life. Flexcin offered something different: a natural formula people have trusted for 25 years. My goal is to build on that legacy and bring it to even more people and pets.”
— Peter St. John, Owner
A Legacy Reinvented
In 2025, healthcare entrepreneur Peter St. John acquired Flexcin with a bold mission: to preserve the brand’s legacy while elevating its potential through innovation, research, and world-class customer care.
With a background in orthopedic joint replacement sales, Peter spent years working directly with surgeons and patients navigating the challenges of joint degeneration. This experience shaped his belief that natural, preventative solutions deserve a bigger place in the conversation about joint health.
How It Started
The Beginning
Flexcin began with a grandson’s determination to help his grandmother. Witnessing her daily discomfort and limited mobility, founder Tamer Elsafy was inspired to search for a better solution. That search led to the discovery of Cetyl Myristoleate (CM8), a compound originally developed by Dr. Harry Diehl, a researcher at the National Institutes of Health.
The Growth
From that moment on, Flexcin grew into a trusted name in joint health. The company earned customer loyalty through real results, genuine compassion, and a foundation in science. CM8 quickly became known for its potential in supporting joint function and reducing discomfort, helping countless individuals regain mobility.
The Science
Dr. Diehl dedicated years to studying natural compounds that support joint comfort and movement. His research led to several patents on CM8. These discoveries became the cornerstone of Flexcin’s joint health formulations, revolutionizing the way we approach joint care.
The magic is in the ingredients.
Our carefully selected ingredients provide advanced joint support, everyday joint comfort, enhanced absorption, and essential structural nutrients. Explore the categories below to learn how each component contributes to your mobility and flexibility.
Cetyl Myristoleate (CM8®)
Enhances joint lubrication. Cetyl myristoleate is a fatty acid ester or, more specifically, a cetylated fatty acid. It is the cetyl ester of myristoleic acid.
Methylsulfonyl Methane (MSM)
Methylsulfonylmethane (MSM provides bioavailable sulfur essential for healthy cartilage and connective tissue. MSM is a natural sulfur compound studied for its role in joint comfort, flexibility, and range of motion. Our pharmaceutical-grade MSM ensures maximum absorption for optimal joint support.
Custom Enzyme Blend
Digestion is dependent on enzymes produced naturally in the body. Larger molecules like Cetyl Myristoleate (CM8) require more effort for the body to digest and absorb. Our natural enzyme blend is a complex proteinaceous substance used to induce and accelerate reactions necessary for metabolism.
