We just raised the bar on protein

Protein powers life. But most bars contain things that don’t belong in yours—they’re loaded with additives and can spike aging pathways in your body. We built something better—a truly clean bar made for strength and longevity.

Designed by scientists at the USC Longevity Institute	14g of complete vegan protein with all essential amino acids and only 170 calories	Extremely clean: No soy, gluten, dairy, GMOs, added sugar or artificial sweeteners

The strength you need—
with no compromise

Your muscle matters. It shapes your body—and your life, supporting weight management, and overall health.

Starting around age 40, muscle declines by 3–8% each decade, making quality protein essential.

But no matter your age, most protein products can accelerate aging—and contain additives that aren’t even on the label.

Based on 25+ years of research, we developed a clean, vegan protein bar that fuels your strength—without spiking aging factors like IGF-1.

No fillers, no junk, nothing to hide. This isn’t just a better bar—it’s longevity nutrition, designed to help you stay strong and age well.

Perfect for pre- or post-workout, a meal on the go, and everyday longevity nutrition
