Is Oolong Tea Good For You? Here’s What You Need To Know About Oxalates
What To Know
- The oxalate content of oolong tea varies depending on factors such as the tea cultivar, growing conditions, and processing methods.
- However, studies have generally shown that oolong tea contains lower levels of oxalates compared to other types of tea, such as black tea and green tea.
- Individuals with a history of kidney stones or those at risk of developing them should limit their intake of oolong tea and other oxalate-rich foods.
Oxalates are naturally occurring compounds found in various plants, including tea leaves. While they can provide certain health benefits, excessive oxalate consumption can lead to health concerns such as kidney stones. This has led many to question whether oolong tea, a popular type of tea, contains significant levels of oxalates.
Understanding Oxalates and Their Health Implications
Oxalates are organic acids that bind to calcium, forming insoluble crystals. These crystals can accumulate in the kidneys, leading to kidney stones. Kidney stones can cause severe pain, urinary tract infections, and even kidney damage if left untreated.
Oolong Tea and Oxalate Content
The oxalate content of oolong tea varies depending on factors such as the tea cultivar, growing conditions, and processing methods. However, studies have generally shown that oolong tea contains lower levels of oxalates compared to other types of tea, such as black tea and green tea.
Oxalate Content of Different Tea Types (mg/100g)
| Tea Type | Oxalate Content |
| — | — |
| Black Tea | 120-200 |
| Green Tea | 80-150 |
| Oolong Tea | 50-120 |
Benefits of Oolong Tea
Beyond its relatively low oxalate content, oolong tea offers various health benefits, including:
- Antioxidant properties: Oolong tea is rich in antioxidants, which can help protect against cellular damage and reduce the risk of chronic diseases.
- Weight loss: Some studies suggest that oolong tea may promote weight loss by increasing metabolism and reducing fat absorption.
- Improved heart health: Oolong tea contains compounds that may help lower cholesterol levels and improve blood flow.
Risks of Excessive Oxalate Consumption
While oolong tea generally has a low oxalate content, consuming excessive amounts can still lead to health risks. Individuals with a history of kidney stones or those at risk of developing them should limit their intake of oolong tea and other oxalate-rich foods.
Symptoms of excessive oxalate consumption include:
- Kidney pain
- Frequent urination
- Blood in the urine
- Nausea and vomiting
Tips for Enjoying Oolong Tea Safely
If you are concerned about oxalate intake, here are some tips for enjoying oolong tea safely:
- Moderate consumption: Limit your daily intake to one or two cups of oolong tea.
- Choose low-oxalate varieties: Opt for oolong teas made with cultivars known to have lower oxalate levels.
- Steep for a shorter time: Over-steeping tea can increase oxalate content. Steep oolong tea for no longer than 3-5 minutes.
- Avoid adding milk: Milk can bind to oxalates and increase their absorption.
Takeaway: The Oxalate Balance
Overall, oolong tea contains lower levels of oxalates compared to other types of tea. While moderate consumption is generally safe, individuals at risk of kidney stones should limit their intake. By following the tips outlined above, you can enjoy the benefits of oolong tea while minimizing the potential risks associated with oxalate consumption.
Questions We Hear a Lot
Q: How much oxalate is considered excessive?

Q: What other foods are high in oxalates?
A: Foods high in oxalates include spinach, rhubarb, beets, nuts, and chocolate.
Q: Can I drink oolong tea if I have kidney stones?
