Product Description
Every mile, every rep, every ride — your tendons, ligaments, and joints take a beating that your protein shakes aren't built to fix. Most athletes focus on muscle recovery and completely ignore the connective tissue that keeps them moving, until something snaps, aches, or starts grinding. Here's what most athletes don't realize: collagen isn't just a skin thing. It makes up 65–80% of your tendons, and your body can't rebuild it efficiently without one critical co-factor — Vitamin C.
The Rho Collagen Synthesis Stack is the exact combination of liposomal marine collagen peptides and liposomal Vitamin C that your body needs to actively rebuild connective tissue — not just supplement it.
Collagen + Vitamin C: The Pairing That Actually Works Research shows Vitamin C is a required co-factor in collagen production — it triggers the chemical reactions that build the collagen helix inside your body. Taking collagen without Vitamin C is like filling your gas tank without a working ignition. This stack delivers both, together, in one daily protocol.
Liposomal Delivery = More Gets In Standard collagen supplements lose a significant amount of their potency during digestion. Rho encases both the collagen peptides and the Vitamin C in liposomes — tiny fat-based protective spheres that shield the nutrients through your gut and support absorption at the cellular level. Most collagen products skip this step entirely.
Clinically Studied Marine Collagen This isn't generic collagen powder. Rho uses Type II Marine Collagen that was tested in a double-blind, placebo-controlled human study — participants saw a 20% reduction in wrinkle appearance and a 38% increase in dermis density over 90 days. That same structural improvement in tissue density is what athletes care about in their joints, tendons, and ligaments.
Collagen is the structural protein — the scaffolding — that holds your tendons, cartilage, ligaments, and skin together. Your body can't simply absorb collagen and slot it directly into your joints. Instead, it breaks the peptides down into amino acids, then uses them as raw material to rebuild collagen where it's needed. The catch: that rebuilding process is energy-intensive and requires Vitamin C as the trigger. Without adequate Vitamin C, those amino acids don't assemble into functional collagen. Research shows collagen synthesis markers stay elevated for up to 72 hours after taking collagen enriched with Vitamin C — and timing it around exercise amplifies the effect even further.
Take it pre-training or pre-activity: Consume your daily serving of both the Liposomal Collagen and Liposomal Vitamin C approximately 45–60 minutes before training — this is when your body's connective tissue repair signals are most active.
Take it daily, consistently: Collagen remodeling takes weeks, not days. Stick to a daily protocol for a minimum of 8–12 weeks to see meaningful changes in joint comfort and tissue resilience.
Pro Tip: Mix both into cold water or a morning smoothie — the collagen is vanilla cream flavored and the Vitamin C is orange zest, so they pair well together and actually taste good.
World Champion Marathoner Ken Rideout and 11x CrossFit Games athlete Noah Ohlsen both trust Rho's formulas for recovery and performance. Athletes who commit to the full stack consistently report improved joint comfort, less day-after stiffness, and skin that holds up to the demands of heavy training seasons.
This isn't just another collagen powder thrown in a tub. This is a precision-dosed, clinically studied, liposomal-delivered collagen synthesis system — built for athletes who treat recovery as seriously as training.

Rho Collagen Synthesis Stack FAQ's
Everything you need to know before getting started.
Take both the Liposomal Collagen and Liposomal Vitamin C about 45–60 minutes before training or physical activity. Research shows that taking collagen enriched with Vitamin C before exercise significantly elevates collagen synthesis markers, helping your body direct repair signals to the tendons and connective tissue being loaded during your workout.
Most athletes start noticing improvements in joint comfort and reduced post-training stiffness within 4–8 weeks of daily use. For the most meaningful connective tissue changes — including tendon resilience and skin density — plan to commit to the stack for at least 12 weeks consistently.
No — and this is the most important thing to understand about collagen supplementation. Vitamin C is a required co-factor in the biochemical process that builds collagen inside your body. Without it, the amino acids from collagen peptides can't assemble into functional collagen structures. This stack pairs them together because that's what the science actually supports.
Marine collagen is sourced from fish and is rich in Type I and Type II collagen — the types most associated with skin structure, joint cartilage, and connective tissue. Type II is specifically the collagen found in cartilage, making it particularly relevant for athletes focused on joint health and mobility. Rho's marine collagen has been studied in a clinical trial showing measurable improvements in skin density and wrinkle reduction.
