RNWY Foundation®

Most injuries aren't accidents. They're cumulative.

Tendons, ligaments, and cartilage don't recover the way muscles do. They have poor blood supply, slow turnover, and they degrade silently over months of training load until one day they don't. Most overuse injuries start long before you feel them.

The problem is most performance nutrition focuses entirely on what happens during training... carbs, protein, pre-workout. Nobody is thinking about the connective tissue that has to hold everything together across hundreds of miles, thousands of foot strikes, and years of training.*

Foundation is built for that. Not the workout. The infrastructure behind the workout: the tendons, ligaments, cartilage, bone density, and baseline hydration that allow you to train consistently without falling apart.*

FORTIGEL® and TENDOFORTE® are not generic collagen. They are specific bioactive peptide compounds with peer-reviewed clinical research specifically targeting the connective tissue structures most vulnerable in endurance athletes.*

FORTIGEL® Bioactive Collagen Peptides

Clinically studied for cartilage: A specific bioactive collagen peptide compound studied across multiple peer-reviewed trials for its ability to stimulate cartilage tissue regeneration. Not generic collagen: FORTIGEL® is engineered to reach and support cartilage specifically, the tissue most degraded by endurance sport.*

TENDOFORTE® Bioactive Collagen Peptides

Clinically studied for tendons: Specifically researched for tendon and ligament health in athletes. Tendons are notoriously slow to adapt and recover: TENDOFORTE® supports the structural integrity of the connective tissue that keeps your stride together over thousands of repetitions.*

Full Electrolyte Complex with 1,400mg daily hydration baseline

Over 1,400mg of electrolytes per serving: sodium, potassium, magnesium, chloride, phosphorus, calcium, and zinc. Not just sodium like most sports drinks. A comprehensive mineral profile to maintain fluid balance, nerve function, and muscle contraction every day.*

Vitamin D3

Bone Health: Endurance athletes, especially those who train indoors or in low-sunlight environments, are at elevated risk for Vitamin D deficiency. D3 is the most bioavailable form, supporting calcium absorption, bone mineral density, and immune function. Critical for stress fracture prevention in runners.*

Vitamin C

Collagen synthesis co-factor: Vitamin C is a required co-factor for collagen synthesis. Without it, the body can't properly form new collagen regardless of how much you consume. Research suggests taking Vitamin C alongside collagen peptides, particularly before exercise, maximizes delivery to connective tissue.*

Built for athletes who train for years, not just seasons.

You're not here for a quick fix. You're building something long-term. Foundation is for athletes who understand that staying consistent matters more than any single workout and that the body has to hold up to make that possible.

• High-mileage runners who accumulate load on knees, hips, and Achilles week after week and need their connective tissue to keep up.
• Cyclists and triathletes managing repetitive joint stress across multiple disciplines over long training blocks.
• Athletes returning from injury who know how fast fitness disappears and want to do everything possible to stay healthy this time.
• Anyone whose connective tissue recovery is slower than it used to be and whose training doesn't account for that yet.
