Our Story

Our journey began with a personal battle against chronic Lyme disease. After years of serious symptoms and limited physical activity, our founder turned to holistic health practices. Through research and experimentation, he discovered the transformative power of amino acids in rebuilding strength, supporting immunity, and restoring hormonal balance—key areas that had been compromised by the disease.

This journey revealed a profound truth: the body has an incredible capacity to recover and thrive when given the right tools. The principles that helped overcome chronic illness—nutrient delivery, reducing inflammation, detoxification, and optimizing mitochondrial function—are identical to mechanisms required to slow the aging process and maintain vitality.

As our founder rebuilt his own strength and resilience, he also recognized the importance of muscle and cardiovascular health as the foundation of longevity. Muscle is more than strength—it supports mobility, independence, and overall well-being as we age. With this insight primeLifespan was born to help others future-proof their strength and enjoy their best years with confidence.

Today, we channel this personal experience and expertise into Strength Renew 50+, a scientifically formulated solution created in collaboration with top health experts. Focused on preserving muscle strength and vitality, it embodies our commitment to empowering you to age well and live fully.
