What is it?

Tart cherry juice is made from sour Montmorency cherries (Prunus cerasus). It’s rich in natural antioxidants and is especially noted for containing melatonin, making it popular as a sleep aid and recovery drink.

How does it work for medicinal purposes?

• Melatonin helps regulate circadian rhythm and sleep cycles.
• Anthocyanins & polyphenols reduce inflammation and oxidative stress, supporting joint and muscle recovery.
• Uric acid-lowering effects help reduce gout attacks.

Active ingredients

• Melatonin
• Anthocyanins
• Quercetin
• Polyphenols

Forms

• 100% tart cherry juice
• Concentrates
• Capsules or powders

Imbalance or deficiency

There’s no tart cherry “deficiency,” but people with low melatonin or chronic inflammation may benefit most.

First medicinal use

Used in traditional medicine for joint pain and inflammation; modern trials began in the 2000s.

What does Tart Cherry Juice help with?

• Post-workout muscle soreness and recovery: Tart cherry is one of the best-studied natural recovery tools for athletes. Its anti-inflammatory compounds reduce the muscle damage and soreness that peaks 24–48 hours after intense exercise, helping you bounce back faster and lose less strength in the days following a hard workout.
• Sleep problems and insomnia: Tart cherry contains natural melatonin and compounds that may boost melatonin production in the body. Clinical trials in adults — including older adults with insomnia — show it can meaningfully increase total sleep time, reduce nighttime waking, and improve overall sleep quality.
• Joint pain and arthritis: The anthocyanins in tart cherry act as natural anti-inflammatories, helping to ease the joint swelling and pain associated with both osteoarthritis and rheumatoid-type inflammation. Some people notice reduced stiffness and less need for over-the-counter pain relievers with regular use.
• Gout flares: Gout is triggered by uric acid crystals building up in the joints. Tart cherry has been shown to lower uric acid levels in the blood and reduce the frequency of gout attacks — likely by both reducing uric acid production and increasing its excretion through the kidneys.
• Exercise-induced inflammation: Hard training naturally spikes inflammatory markers in the blood. Tart cherry consumed before and after exercise blunts this inflammatory response, protecting muscle tissue and supporting faster restoration of full strength — especially important for endurance athletes and those training multiple days in a row.
• High uric acid levels: Even outside of gout, elevated uric acid is linked to kidney issues and cardiovascular risk. Tart cherry consumption has been shown to reduce serum uric acid levels, offering a dietary strategy to keep levels in a healthier range.
• High blood pressure: Some clinical studies suggest tart cherry can modestly lower systolic blood pressure, likely through the vasodilating and anti-inflammatory effects of its polyphenols. It works best as part of an overall heart-healthy diet and lifestyle.
• Osteoarthritis pain: In people with knee osteoarthritis, tart cherry juice has been shown to reduce pain scores and inflammatory markers like CRP. It does not reverse joint damage, but it can meaningfully reduce daily pain and improve function over weeks of regular use.
• Oxidative stress and antioxidant support: Tart cherries rank among the highest-antioxidant fruits tested. The dense concentration of polyphenols helps neutralize free radicals that contribute to aging, chronic disease, and slow recovery — making it a solid everyday antioxidant food as well as a therapeutic tool.
• Cognitive decline and brain health: Early research suggests the anti-inflammatory and antioxidant compounds in tart cherry may help protect the brain from age-related decline, with some studies showing improvements in memory and attention in older adults. This is an emerging area with promising but still-building evidence.

What can Tart Cherry Juice help prevent?

• Recurrent gout attacks: regular tart cherry consumption is associated with significantly fewer gout flares
• Exercise-induced muscle damage: pre-loading with tart cherry before intense events reduces muscle breakdown markers
• Age-related oxidative stress: consistent dietary intake may slow accumulation of oxidative cellular damage
