Tart Cherries: A Closer Look at Magnesium Content
The perception of tart cherries as a high-magnesium food is a common misconception, often stemming from their association with supplements that combine them with concentrated magnesium sources for better sleep. In reality, the natural magnesium content in the fruit itself is quite low compared to other, more concentrated sources. The amount can also vary depending on how the cherries are consumed.
Magnesium in Different Tart Cherry Forms
- Fresh Tart Cherries: A standard one-cup serving of fresh, raw tart cherries contains approximately 13-15 mg of magnesium, which provides only a fraction of an adult's daily needs.
- Tart Cherry Juice: A one-cup (8-ounce) serving of 100% tart cherry juice contains roughly 30 mg of magnesium, which is a higher concentration than the raw fruit but still only 7% of the daily value. This slight increase is due to the concentration process.
- Tart Cherry Juice Concentrate: The concentrate offers a much higher dose per serving due to the removal of water. One ounce of a typical tart cherry juice concentrate can contain over 12 mg of magnesium, though products can be fortified to contain even higher levels. However, it is important to remember this is not the natural state of the fruit.
- Dried Tart Cherries: Dried and sweetened versions contain about 10 mg of magnesium per serving, but often have a higher sugar content than the raw fruit.
How Tart Cherries Compare to Other Magnesium Sources
When evaluating whether tart cherries are a high source of magnesium, it is most helpful to compare them directly to foods that are truly rich in the mineral. The recommended daily intake for adults ranges from 310 to 420 mg. As the comparison table below shows, many other foods offer a far more significant contribution to meeting these daily needs.
Top Magnesium Sources vs. Tart Cherries
| Food (Serving Size) | Magnesium Content (mg) | Comparison to Tart Cherries (1 cup = ~15 mg) |
|---|---|---|
| Pumpkin Seeds (¼ cup) | 150–175 mg | More than 10x the magnesium of a cup of tart cherries. |
| Spinach (1 cup, cooked) | 155 mg | Over 10x the magnesium of a cup of tart cherries. |
| Almonds (1 ounce) | 70 mg | Nearly 5x the magnesium of a cup of tart cherries. |
| Black Beans (½ cup, cooked) | 60 mg | 4x the magnesium of a cup of tart cherries. |
| Avocado (½ medium) | 23 mg | A moderately higher source, but not by a large margin. |
| Tart Cherries (1 cup, raw) | ~15 mg | The baseline for this comparison. |
Beyond Magnesium: The Full Nutritional Profile of Tart Cherries
While not a magnesium powerhouse, tart cherries are undeniably a nutrient-dense fruit with several other beneficial compounds. Their true claim to fame lies in their high levels of antioxidants, particularly anthocyanins, and their natural melatonin content, which is well-researched for its potential to support sleep and reduce inflammation.
Other Notable Health Benefits of Tart Cherries
- Antioxidant Power: Tart cherries contain significantly higher levels of antioxidants compared to sweet cherries. These compounds help combat oxidative stress and can help reduce inflammation throughout the body.
- Improved Sleep Quality: The natural presence of melatonin and tryptophan in tart cherries and their juice contributes to regulating the sleep-wake cycle, potentially improving sleep quality and duration. The popular 'Sleepy Girl Mocktail' is often made with tart cherry juice and added magnesium for this reason.
- Post-Exercise Recovery: Studies suggest that consuming tart cherries can aid in muscle recovery after strenuous exercise by reducing muscle soreness and oxidative damage.
- Heart Health: The anthocyanins and other compounds in tart cherries may support cardiovascular health by helping to lower blood pressure and LDL cholesterol levels.
- Immune System Support: Rich in vitamins A and C, along with other nutrients, tart cherries can contribute to a robust immune system.
Maximizing Magnesium Intake from Your Diet
For those looking to increase their magnesium intake, relying on tart cherries alone would be inefficient. A balanced diet incorporating a variety of whole foods is the most effective strategy. Aim for a mix of dark leafy greens, nuts, seeds, and legumes to easily meet your daily recommended allowance. Adding tart cherries to this diet can still provide a small nutritional boost, but should not be your primary magnesium source.
- Incorporate more leafy greens: Add spinach or Swiss chard to salads, smoothies, or cooked dishes.
- Snack on nuts and seeds: Carry almonds, cashews, or pumpkin seeds for a convenient magnesium boost.
- Use legumes: Mix black beans or edamame into meals. Tofu is also a great source.
- Include whole grains: Opt for whole grains like brown rice or quinoa over refined grains.

Conclusion: The Final Verdict on Tart Cherries and Magnesium
To definitively answer the question, "Are tart cherries high in magnesium?", the answer is no. While they contain the mineral, their contribution to the daily recommended intake is minimal compared to other well-known magnesium-rich foods. Tart cherries are, however, excellent sources of other beneficial nutrients, including antioxidants and natural melatonin, which offer significant health advantages, especially for sleep and inflammation management. For those seeking to boost their magnesium levels, the focus should remain on incorporating a wide array of high-magnesium foods into their diet, using tart cherries to supplement rather than as a primary source.
