Build lean muscle and improve athletic recovery with RNWY Complete Protein.
This isn't whey. It's not pea. It's something better.
Most protein powders ask you to choose between digestibility and completeness. Animal proteins are complete but hard on the gut. Plant proteins are gentler but often lack the full amino acid spectrum. RNWY Complete Protein is neither.
YESTEIN® is a slow-digesting protein derived from fermented nutritional yeast, the first of its kind in sports nutrition. Fermentation makes it bioavailable, gut-friendly, and delivers every essential amino acid your body can't produce on its own. Peer-reviewed research shows it performs on par with whey for muscle building, without the dairy, without the bloat.*
For athletes, slow digestion means sustained amino acid delivery over several hours... exactly what endurance athletes, runners, and high-volume trainers need for ongoing recovery between sessions.

INGREDIENT DEEP DIVE
YESTEIN® Fermented Yeast Protein, 32g (25g protein)
A complete protein source with all 9 essential amino acids including leucine, the key trigger for muscle protein synthesis. Fermentation breaks down the cell wall of nutritional yeast, dramatically improving bioavailability without digestive stress. Slow-digesting and keeps your muscles fed for hours, not minutes. 100% vegan, non-GMO, and free from the 14 major allergens.*
Creatine Monohydrate, 5g
The most researched performance supplement on the planet — and it's already in your shake. 5g daily creatine monohydrate has been clinically shown to increase power output, improve sprint and high-intensity performance, and accelerate recovery between hard efforts. No separate scoop. No extra product. Just included.*
Digestive Enzyme Complex, 150mg
Protease, amylase, lipase, cellulase, and lactase work together to break protein into absorbable peptides and amino acids faster. Protein that you can't absorb is protein you can't use. These enzymes make sure nothing goes to waste and keep your gut comfortable post-workout.*
BUILT FOR YOU
As an athlete who trains daily, recovers hard, and eats clean, you're not looking for a sugary shake to throw back after a casual gym session. You train consistently. You care what goes in your body. You want a protein that works as hard as you do. Plus it fits a vegan or plant-forward lifestyle without compromise.
Complete Protein was designed for:
Endurance athletes including runners, cyclists, and triathletes who need sustained amino acid release across long training blocks.
Strength + hybrid athletes who want creatine's power and protein's recovery without managing two products.
Vegan and plant-based athletes who've struggled to find a complete protein without compromising amino acid quality.
Sensitive stomachs who've had to give up whey or casein because of GI issues mid-training.
HOW TO USE
Complete Protein works best as your post-workout recovery fuel. Combine 1 serving (1/3 cup) with 10-12 fl. oz. of water or your favorite milk. You can also add to your favorite smoothie. Shake or blend. Make it a daily habit for best results.
