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 + Glycine

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.

Glycine + Magnesium Bisglycinate

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.

L-Theanine + Magnesium Bisglycinate

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).

Taurine + L-Theanine

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.

When Each Ingredient Kicks In

From the first sip to overnight repair - here is the timeline.

0 min

15 min

Sodium rehydration + electrolyte balance restoring

30 min

L-Theanine crosses blood-brain barrier, alpha waves increase

1 hr

Glycine and magnesium absorption underway, muscle relaxation begins

Night

Glycine lowers core temp, magnesium deepens sleep, collagen synthesis peaks

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.

Glycine ingestion improves subjective sleep quality in human volunteers

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.

The effect of magnesium supplementation on primary insomnia in elderly

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.

L-theanine, a natural constituent in tea, and its effect on mental state

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.

Normative data for sweating rate, sweat sodium concentration, and sweat sodium loss in athletes

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.
