I Drank Tart Cherry Juice Every Day for a Week—Here’s What Really Happened to My Body
Why I Tried Tart Cherry Juice Every Day for a Week
As a 45-year-old dietitian, I think about muscle and sleep a lot more than I did in my 20s. I lift weights, I try (and sometimes fail) to get to bed on time, and I’m acutely aware of how aging can chip away at muscle mass and recovery. Sarcopenia—the gradual loss of muscle with age—isn’t just a textbook term for me; it’s something I see in clients and want to prevent in myself.
Tart cherry juice kept coming up in conversations about better sleep, reduced soreness, and joint comfort. Rather than just skimming the research, I decided to become my own case study: drink tart cherry juice every day for a week and track what actually changed in my body.
In this article, I’ll walk you through what I did, what I felt, what the science supports (and doesn’t), and how to safely try tart cherry juice yourself if you’re curious about sleep, muscle recovery, or inflammation.
The Real Problem: Aging Muscles, Soreness, and Stubborn Sleep
After 40, we naturally start to lose muscle mass and strength, especially if we’re not lifting regularly. At the same time, many of us notice:
- More soreness after workouts that used to feel “easy”
- Stiffness in the morning or after sitting too long
- Lighter, more fragmented sleep—or trouble staying asleep
- Longer recovery time between strength or cardio sessions
I see this pattern in my clients: they want to stay active, but soreness, pain, or poor sleep make it harder to keep up a consistent routine. That’s exactly where tart cherry juice has gained attention—as a natural, food-based strategy that may support recovery and sleep, without promising miracle cures.
My 7-Day Tart Cherry Juice Experiment: How I Structured It
I designed a simple one-week experiment that would fit my normal life, not a lab environment. The goal wasn’t perfection—it was to see what tart cherry juice might realistically do for a busy, active 45-year-old.
- Product: I chose a 100% tart cherry juice, not a blend or “cocktail,” so I knew what I was testing.
- Dosage: 8 ounces (about 240 mL) twice daily, which is similar to doses used in many research studies.
- Timing: One glass in the late afternoon and one about 60–90 minutes before bed.
- Baseline: I kept my workouts, meals, supplements, and bedtime routine as consistent as possible for comparison.
- Tracking: I logged:
- Sleep quality (time to fall asleep, wake-ups, restedness)
- Muscle soreness (especially after lifting days)
- Joint stiffness (knees and hips in the morning)
- Digestion, energy levels, and any side effects
“Self-experiments aren’t perfect science, but they can be powerful when paired with actual research. My goal was to notice patterns, not to prove causation.”
What I Noticed in 7 Days: Sleep, Soreness, and Side Effects
One week is short, so I wasn’t expecting dramatic changes in muscle mass or strength. But I did notice meaningful shifts in how my body felt day to day.
1. Sleep: Easier to Drift Off, Fewer Toss-and-Turn Nights
By night three, I noticed I was falling asleep a bit faster—more like 10–15 minutes instead of my usual 20–30. I also had fewer “wide-awake at 3 a.m.” episodes.
- On most nights: I felt sleepier around my usual bedtime and woke up feeling slightly more rested.
- On one night: Stress totally overrode any benefit, reminding me that no juice can cancel out a racing mind.
2. Muscle Soreness: Noticeably Softer Edges After Hard Workouts
I scheduled two heavier lifting days during the week (squats, deadlifts, and some upper-body work). Normally, I’d expect moderate soreness, especially the next morning.
With tart cherry juice on board, the soreness was still there—but muted. Stairs were less of a “why did I do this to myself?” situation, and my muscles felt more like I’d had a solid training session than a complete beatdown.
3. Joint Stiffness: Subtle, But Real, Morning Improvements
I tend to feel creaky in my hips and knees first thing in the morning. Over the week, I noticed:
- Standing up from bed felt a bit easier
- Less “need to warm up” feeling when heading into a walk
- Still some stiffness after long periods of sitting
4. Side Effects: Sugar, Digestion, and Practical Downsides
Tart cherry juice isn’t magic—it’s still a source of sugar and calories. For me:
- Blood sugar: I felt best when I drank it with or after a meal or snack, not on an empty stomach.
- Digestion: No major issues, but on one day with multiple high-fiber meals and the juice, I felt slightly bloated.
- Practicality: It’s not cheap if used daily, and it requires fridge space and planning.
What Science Says About Tart Cherry Juice: Sleep, Recovery, and Inflammation
Tart cherries are rich in polyphenols, especially anthocyanins—the compounds that give them their deep red color. These have antioxidant and anti-inflammatory properties, which is where many of the health claims come from. Here’s what current research suggests, with the caveat that many studies are small and short-term.
1. Sleep Support and Melatonin
Tart cherries naturally contain melatonin and may influence tryptophan, an amino acid involved in sleep regulation. Some small randomized studies have found that tart cherry juice:
- Can modestly increase total sleep time
- May improve sleep efficiency (time asleep vs. time in bed)
- Appears more helpful for people with mild to moderate insomnia than for very heavy sleep disturbances
It’s not as potent as prescription sleep medications, but for some people, it may offer a gentle nudge toward better sleep, especially when combined with solid sleep hygiene.
2. Muscle Recovery and Exercise-Induced Soreness
Several studies in athletes and recreational exercisers have evaluated tart cherry juice around intense training or endurance events. Overall, research suggests it can:
- Reduce post-exercise muscle soreness
- Limit strength loss following tough workouts or races
- Decrease markers of muscle damage and inflammation in some trials
Not every study shows dramatic effects, and protocols vary, but the trend is promising—especially for people doing heavy strength work or endurance training.
3. Inflammation and Joint Health
Tart cherry juice has been studied for joint pain and inflammatory conditions like osteoarthritis and gout. Findings suggest:
- Some people with osteoarthritis reported reduced pain and improved function
- Tart cherry products may help lower certain markers of inflammation
- There is cautious interest in gout support due to potential uric acid–lowering effects, but results are mixed
More research is needed, especially long-term and in larger groups. Tart cherry juice shouldn’t replace medications or medical guidance for arthritis or gout, but it may be a supportive add-on for some.
“Tart cherry juice appears to be a useful adjunct for sleep and recovery in certain individuals, but it’s not a one-size-fits-all solution. It’s best viewed as part of a broader lifestyle approach.”

Before vs. After: How My Body Felt by the End of the Week
Again, one week can’t transform your body composition—but you can notice trends. Here’s how I’d summarize my “before and after.”
| Area | Before Tart Cherry Juice | After 7 Days |
|---|---|---|
| Falling asleep | 20–30 minutes on average | Closer to 10–15 minutes most nights |
| Night awakenings | 2–3 brief wake-ups | 1–2, usually shorter |
| Post-workout soreness | Moderate soreness, noticeable with stairs | Mild to moderate soreness, more manageable |
| Morning joint stiffness | Creaky knees and hips on standing | Slightly improved; still present but less intense |
| Energy and digestion | Stable, no major issues | Similar overall; one mildly bloated day with higher-fiber meals |
How to Try Tart Cherry Juice Safely and Effectively
If you’re curious about adding tart cherry juice for sleep or muscle recovery, here’s a practical, health-conscious way to experiment.
1. Choose the Right Product
- Look for: 100% tart cherry juice or a concentrate you dilute yourself.
- Avoid: “Cocktails” or blends with lots of added sugars.
- Check labels: Some brands are significantly higher in sugar and calories per serving.
2. Decide on a Starting Dose
Many studies use about 8–12 ounces (240–355 mL) of juice per day, or an equivalent amount in concentrate. A reasonable trial plan:
- For sleep: 8 ounces about 60–90 minutes before bed.
- For recovery: 8–16 ounces total across the day, with one serving after training.
- Trial length: 7–14 days is long enough to see if you notice a pattern.
3. Pair It with Solid Habits
Tart cherry juice works best as a complement—not a replacement—for:
- Consistent strength training (2–3 days per week)
- Adequate daily protein intake
- Stretching or mobility work, especially after workouts
- Good sleep hygiene: regular bedtime, lower evening screen time, and a dark, cool room
Who Should Be Careful with Tart Cherry Juice?
While tart cherry juice is generally safe for most people when used in moderation, there are a few important cautions.
- If you have diabetes or insulin resistance: The natural sugars may affect blood glucose. If you try it, do so with food and monitor your response, ideally with guidance from your healthcare provider.
- If you’re on medications: Especially blood thinners, blood pressure medications, or drugs for gout, check with your doctor or pharmacist about potential interactions.
- If you have kidney issues: Large amounts of some juices can be a concern for certain kidney conditions; get individual medical advice before adding it regularly.
- If you’re prone to digestive issues: Start with a smaller serving to see how your body responds.
Key Takeaways: Is Tart Cherry Juice Worth It?
After a week of drinking tart cherry juice every day, here’s how I’d sum it up—for myself and for my clients.
- Sleep: I noticed slightly easier sleep onset and fewer awakenings, aligning with small but positive research findings.
- Muscle recovery: Post-workout soreness felt more manageable, and I bounced back a bit faster between lifting sessions.
- Joint comfort: Mild improvement, not a dramatic change—but enough that I noticed.
- Downsides: Added sugar and calories, cost, and the need to be mindful if you have blood sugar or kidney concerns.
Is tart cherry juice a must-have? No. Is it a potentially helpful, evidence-supported tool for better sleep and recovery—especially if you’re active or over 40? In many cases, yes.
If you decide to try it, give yourself 1–2 weeks, keep the rest of your routine steady, and pay close attention to how you actually feel—overnight, after workouts, and throughout your day.
Your body will tell you whether tart cherry juice is worth keeping in your routine. Listen to it, pair it with smart training and sleep habits, and don’t be afraid to adjust based on what genuinely works for you.
