The Science Behind the Can
5 Ingredients. All Studied.
Zero Guesswork.
Every ingredient is published. Every dose is clinical. Every claim links to a peer-reviewed study. RCVR exists because recovery shouldn't require blind trust in a proprietary blend.
Why These 5 Together
Most recovery products throw 20 ingredients at a wall. RCVR uses 5 - each chosen because they amplify the others.
Taurine
2,000mgAntioxidant Defense
Glycine
3,000mgSleep + Collagen
Magnesium Bisglycinate
300mg elementalMuscle + Sleep
L-Theanine
200mgCalm Focus
Protect and Rebuild
Taurine neutralizes exercise-induced oxidative damage at the cellular level while glycine provides the primary building block for collagen synthesis. One defends, the other repairs.
Deep Recovery Architecture
Glycine lowers core body temperature to trigger deeper sleep stages. Magnesium activates the parasympathetic nervous system and boosts growth hormone release during those same stages. Together they optimize the conditions where tissue repair actually happens.
From Stress State to Recovery State
L-Theanine calms the nervous system while magnesium relaxes muscles and promotes GABA activity. Combined, they shift you from sympathetic (fight-or-flight) to parasympathetic (rest-and-repair).
Cellular Calm
Taurine has mild inhibitory effects on the nervous system and protects cells from oxidative stress. L-Theanine promotes alpha brain wave activity and lowers cortisol. Two distinct pathways to the same outcome: calm without sedation.
The result
Complete Recovery
4 active compounds covering oxidative stress, connective tissue repair, muscle relaxation, and calm focus - the full recovery cascade in a single can.
The Ingredients
Every ingredient. Every dose. Every study.

The role of taurine in mitochondria health: more than just an antioxidant
Molecules, 2021
Review confirmed taurine's role in mitochondrial function, demonstrating that it buffers oxidative stress within mitochondria and supports electron transport chain efficiency - directly relevant to cellular energy recovery post-exercise.

Sleep and Biological Rhythms, 2006
3g glycine before bedtime significantly improved subjective sleep quality and reduced fatigue and sleepiness the following day in participants with mildly impaired sleep, without altering sleep architecture on polysomnography.

Journal of Research in Medical Sciences, 2012
Magnesium supplementation (500mg/day for 8 weeks) significantly improved subjective sleep quality, sleep time, sleep efficiency, and serum melatonin levels while reducing cortisol in elderly subjects with insomnia.

Nutritional Neuroscience, 2008
EEG measurements confirmed that 50mg of L-theanine significantly increased alpha brain wave activity within 45 minutes of ingestion, indicating relaxation without drowsiness.

Journal of Sports Sciences, 2019
Across 506 athletes, mean sweat sodium concentration was 36.2 mmol/L (833 mg/L) with wide individual variation. Mean sweat rate was 1.13 L/hr. A 30-45 minute workout typically produces 300-700mg of sodium loss.
