Introduction

As research grows around the natural health benefits of tart cherries, one question continues to surface: “Does cherry juice have any side effects?”

Before addressing that directly, it’s worth understanding why so many people are turning to Montmorency tart cherry juice — often called Michigan’s ruby-red superfruit — for its wellness potential.

The Research Behind Cherry Juice Benefits

Over the past two decades, leading U.S. universities have studied how tart cherries may naturally support joint comfort, muscle recovery, and restful sleep.

Research shows that tart cherries contain several key compounds, including:

• Anthocyanins: Natural pigments with antioxidant and anti-inflammatory properties.

• Potassium: A mineral that helps regulate muscle and nerve function.

• Melatonin: A natural hormone that supports healthy sleep cycles.

These compounds work synergistically, meaning their combined effects may help maintain joint health and reduce occasional soreness from physical activity.*

Tart Cherries and Melatonin for Sleep

The melatonin content in tart cherries is another reason this fruit stands out.
Dr. Russel Reiter, known as the “Dean of Melatonin Research,” confirmed that tart cherries contain more natural melatonin than any other fruit or vegetable studied to date.

• Cherry juice concentrate contains roughly 100 ng of natural melatonin per serving.

• Tart cherry powder offers approximately 137 ng per serving.

Unlike synthetic melatonin supplements, these amounts come directly from nature — making cherry juice a gentle, food-based way to support restful, quality sleep.

Cherry Juice and Muscle Recovery

Athletes and active individuals have also turned to cherry juice for muscle recovery.
The combination of potassium, anthocyanins, and antioxidants helps the body reduce oxidative stress after intense exercise — which may support faster recovery and reduced soreness.

Are There Any Side Effects?

For most healthy adults, drinking cherry juice in moderation is considered safe.
There are no major documented side effects reported by leading research institutions.

However, one thing to be aware of is natural sugar content.
Tart cherry juice naturally contains around 15 grams of sugar per serving, primarily from fructose — not added sugar.

If you’re monitoring your sugar intake or following a low-sugar diet, consider tart cherry capsules instead. Each serving contains less than 1 gram of sugar while still providing the natural compounds found in the fruit.
