Is your protein
aging you?
You're eating protein to be healthy—it's the fuel, and building block, of your body. But many protein formulations on the market spike pro-aging pathways like IGF-1, and they're packed with hidden sugars and other additives that can compromise your health.
Prolon longevity protein is the world's first precision nutrition formulation developed at the Longevity Institute of the University of Southern California and IFOM research center in Italy to support muscle while not spiking pro-aging factors in the body.

Why longevity
protein?
Your muscle matters
It doesn't just shape your body, it can shape your life, playing a vital role in weight management, disease prevention, and overall well-being. And starting around age 40, muscle naturally declines by 3-8% each decade, making quality protein essential for protecting lean mass.
Here's the problem: no matter your age, most protein products that rely on animal sources like whey can accelerate aging. And they often contain hidden additives like silica and artificial flavors that don't even have to appear on the label.
IGF-1: Balance is
everything
Protein consumption affects your levels of a key hormone called insulin-like growth factor 1, or IGF-1. Eating too much of certain kinds of animal proteins (like those often found in many protein bars and powders) can spike IGF-1. Overstimulating IGF-1 can accelerate aging and increase disease risk. Too little protein intake can be just as harmful health-wise, and accelerate aging in its own right.
The key is balance—getting the optimal amount of protein from sources that support muscle without triggering this aging cascade. Based on our decades of research into nutrition, and our studies on optimal IGF-1 levels, we developed our longevity proteins to support muscle—without triggering pro-aging pathways.
