The Recovery Secret Pro Cyclists Have Been Using for Years
If you watched pro cycling over the last few years, you may have noticed something at stage finishes: riders grabbing small bottles of dark red liquid before they even touched their protein shakes. It wasn't a sports drink. It was tart cherry juice — and those teams weren't doing it for the taste. Elite endurance athletes quietly adopted Montmorency cherry as a race-week recovery staple long before it showed up in mainstream nutrition circles, because the research backing it is some of the strongest in natural recovery science.
SiS REGO Cherry Juice is a single-ingredient recovery shot — 100% Montmorency sour cherry concentrate in a convenient 30ml sachet — designed to reduce muscle soreness, ease joint inflammation, and support the sleep your body needs to actually rebuild.
Just One Ingredient – REGO Cherry Juice is exactly what it says: concentrated Montmorency cherry juice, nothing else. No additives, no artificial sweeteners, no protein powder fillers. Just the most research-backed natural recovery compound in endurance sport, in its most direct form.
Recovery and Sleep Support – Montmorency cherries are naturally rich in anthocyanins — the anti-inflammatory compounds that give tart cherries their deep red color — as well as flavonoids and naturally occurring melatonin. The anthocyanins and flavonoids go to work on post-exercise inflammation and oxidative stress. The melatonin helps regulate your sleep cycle, improving both the quality and duration of rest — the window where most of your actual recovery happens.
Built for Back-to-Back Days – Elite cyclists, marathon runners, and triathletes have incorporated tart cherry protocols into race week and multi-day training blocks for years. The loading approach — twice daily for several days before and after key efforts — is directly backed by research in endurance athletes. A 2010 study found that marathon runners using this protocol experienced significantly less muscle pain and faster recovery than a placebo group.
How to Use SiS REGO Cherry Juice
Loading Protocol: Take one 30ml sachet in the morning and one in the evening for 4–5 days before a target event, continuing for 2–3 days post-race to manage the recovery window.
Post-Workout Use: A single sachet immediately after a hard training session also works as a standalone recovery tool on non-event days.
How to Take It: Dilute one sachet in 250–350ml of water, or mix into a post-workout shake or smoothie. The tart flavor holds up well in both.
This isn't just cherry juice. This is a clinically studied, single-ingredient recovery tool that addresses the three things your body needs most after a hard effort: less soreness, less inflammation, and better sleep.

SiS REGO Juice FAQ's
Everything you need to know about SiS REGO Juice.
REGO Cherry Juice is a 30ml concentrated shot of 100% Montmorency sour cherry — one ingredient, nothing added. It works through three separate recovery pathways simultaneously: anthocyanins and flavonoids reduce post-exercise inflammation and oxidative stress to speed muscle repair, naturally occurring melatonin helps regulate your sleep cycle for deeper, more restorative rest, and the combined anti-inflammatory action helps reduce joint soreness that accumulates during high-mileage training. Most recovery products address one of these areas. This one addresses all three in a single sachet.
Not all cherries are equal for recovery. Montmorency is a specific variety of sour cherry with a significantly higher concentration of anthocyanins and flavonoids — the anti-inflammatory compounds responsible for the recovery effects — compared to sweet cherry varieties. It also contains meaningfully higher levels of naturally occurring melatonin. Regular cherry juice or cherry-flavored products made from sweet cherries don't carry the same research backing or the same bioactive compound profile. When research studies on tart cherry and athletic recovery reference their results, they're using Montmorency specifically.
DOMS — delayed onset muscle soreness — is the deep muscle ache that peaks 24–72 hours after hard or unfamiliar exercise. It's caused by microscopic damage to muscle fibers triggering an inflammatory response as the body begins repair. The anthocyanins in Montmorency cherry concentrate work by reducing that inflammatory cascade, which doesn't eliminate soreness entirely but meaningfully blunts its peak intensity and shortens how long it lingers. For athletes training on back-to-back days or in stage-race format, the difference between manageable soreness and compromised training is often the recovery work happening in between.
Montmorency cherries are one of the few whole foods with a naturally significant melatonin content, which makes the sleep benefit a natural part of the product rather than an added ingredient. Melatonin is the hormone that sets your body's circadian rhythm — it signals when to sleep and when to wake. Research has shown that supplementing with tart cherry juice over as few as three days can improve both sleep quality and duration in athletes. For endurance athletes, sleep is the window where the majority of physiological adaptation and tissue repair actually happens, so improving sleep quality is a direct performance investment.
Yes, and many endurance athletes do. The anti-inflammatory and sleep-support benefits are relevant regardless of whether you're in a race week. Using one sachet daily — morning or evening — provides consistent anthocyanin intake that supports ongoing recovery from regular training load. The loading protocol is specifically designed for the days around targeted peak efforts, but there's no reason to restrict it to race periods only. Athletes who train high volume tend to get the most consistent value from daily use.
