About Longevity Performance

Hi, I'm Luis—58 years young, and the founder of Longevity Performance USA.

A few years back, right around age 50, I hit a turning point. I was around 218 pounds, feeling the effects of processed foods, fast food, alcohol, and a lifestyle that wasn't serving me anymore. I decided to change everything: I quit drinking completely, eliminated processed junk and fast food, shifted to a mostly ketogenic/low-carb approach (one solid meal a day built around high-quality meats like beef, chicken, and pork), and committed to regular exercise.

The results? I dropped about 50 pounds, kept it off, and gained back energy and mobility I thought were gone for good. Comprehensive bloodwork through advanced testing now shows my biological age around 46—not about reversing time, but making every year ahead count with strength and independence.

As we move into our 50s and beyond, the real keys to staying mobile and vibrant are preserving muscle mass, supporting joints, and fueling recovery naturally. But getting enough high-quality protein daily gets tougher, and recovery slows. That's why I created Longevity Performance—clean, no-nonsense supplements to make those principles easier to live every day.

Our focus is simple and effective:

  • Grass-fed Whey Protein Isolate — Minimal ingredients for an effortless 28g protein boost to help maintain and build muscle.
  • Grass-fed Collagen Peptides — Targeted support for joints, tendons, and overall mobility.
  • More in the works to round out a true longevity stack.

This is what I use myself, grounded in real experience and the science of healthy aging. My YouTube channel dives deeper into these topics—foundational nutrition and mindset on Mondays, practical movement and stretching on Thursdays.

If you're 50+ and want to stay strong, mobile, and active longer, you're in the right place. Let's keep the clock ticking with quality.
