The Science Behind the Can

3 Ingredients. 50+ Studies.
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 3 Together

Most recovery products throw 20 ingredients at a wall. RCVR uses 3 - each chosen because they amplify the others.

Montmorency Tart Cherry

Equivalent of 40 cherries

Inflammation

L-Theanine

200mg

Cortisol

Magnesium Bisglycinate

200mg

Muscle + Sleep

Montmorency Tart Cherry + L-Theanine

Faster Inflammation Resolution

Anthocyanins reduce inflammation while L-Theanine lowers cortisol - a key inflammation amplifier. Together they attack inflammation from both the physical and neurological sides.

Montmorency Tart Cherry + Magnesium Bisglycinate

Damage by Day, Repair by Night

Tart cherry fights exercise-induced oxidative damage during the day while magnesium bisglycinate promotes deep sleep cycles 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).

The result

Complete Recovery

3 ingredients covering inflammation, stress, and sleep - the full recovery cascade in a single can.

The Ingredients

Every ingredient. Every dose. Every study.

Montmorency Tart Cherry

Prunus cerasus (Montmorency)

Equivalent of 40 cherries

Montmorency tart cherries contain the highest concentration of anthocyanins and melatonin of any food. The research is unusually strong for a natural ingredient - reduced muscle soreness, lower inflammatory markers, better sleep. Each RCVR delivers the equivalent of 40 cherries in a single can.

Marathon runners consuming tart cherry juice showed significantly faster recovery of isometric strength and reduced inflammation (IL-6) compared to placebo over 48 hours post-race.

L-Theanine

L-γ-glutamylethylamide

200mg

L-Theanine is an amino acid found almost exclusively in tea leaves. At 200mg - the dose in every RCVR - it promotes alpha brain wave activity, the neural signature of calm focus. It reduces cortisol, the stress hormone that blocks recovery, without causing sedation. This is the difference between a supplement that makes you drowsy and one that makes you recovered.

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

3 studies cited

Magnesium Bisglycinate

Magnesium bis-glycinate chelate

200mg

Most magnesium supplements use oxide or citrate - cheap forms with poor absorption and GI side effects. Bisglycinate is chelated (bonded to glycine), which dramatically increases bioavailability and eliminates the laxative effect. It supports 300+ enzymatic reactions including muscle relaxation, protein synthesis, and sleep regulation. RCVR uses 200mg of the bisglycinate form because the dose only matters if it gets absorbed.

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.
