SiS REGO Cherry Juice

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.
