Our Story

Our journey began with a personal battle against chronic illness. After years of limited physical activity, our founder turned to holistic health practices. Through research and experimentation, he discovered the transformative power of targeted nutrition and supplementation in rebuilding strength, supporting immunity, and restoring hormonal balance.

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 the mechanisms required to slow the aging process and maintain vitality.

As our founder rebuilt his own strength and resilience, he returned to the pursuits and passions he refused to give up — windsurfing, foilboarding, and staying physically active well into his later years. He recognized that muscle and cardiovascular health aren't just markers of fitness — they are the foundation that lets you keep doing what you love. With this insight, primeLifespan was born to help others future-proof their strength and enjoy their most active 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.

Reinhard Seidel MSc, Founder, California, USA

Reinhard Seidel is a product development specialist and functional health enthusiast with over 20 years of experience in nutrition, longevity science, and performance supplementation. At the heart of everything he does is a simple belief: age should not be the reason you stop doing what you love.

Reinhard lives that belief every day — out on the water windsurfing and foilboarding, and refusing to slow down. His drive to keep performing at a high level, combined with his personal journey overcoming a chronic illness, sparked a deep dive into the science of muscle longevity, inflammation management, and mitochondrial health — and ultimately led him to develop the supplement formulations behind primeLifespan.

He created Strength Renew 50+ for everyone who, like him, has a passion, or an adventure they're not ready to give up — and wants the physical foundation to keep pursuing it well into their 50s, 60s, 70s, and beyond.

As the founder of primeLifespan, Reinhard's mission is straightforward: help active adults stay strong, resilient, and in the game — for as long as they want to play."
