According to Healthlinethe primary difference between green and black tea lies in their production process. Black tea leaves are rolled and oxidized, which causes them to turn dark brown, while green tea leaves remain unoxidized, preserving their green color. This oxidation process gives each tea its distinct flavor and nutritional properties, though both are rich in antioxidants.

Shared benefits of green and black tea

Both green and black tea offer several similar health benefits.

According to Very Well Fitstudies have shown that both green and black tea can help lower LDL (“bad” cholesterol) and triglycerides. Research reviews also suggest that drinking black or green tea daily may effectively lower blood pressure. Furthermore, consuming up to three cups of either tea daily has been linked to a reduced risk of heart attack and stroke.

Both teas also contain caffeine, which helps boost alertness and reduce fatigue. Green tea contains about 29 mg of caffeine per 8-oz (237 ml) cup, while black tea contains 47 mg. They also contain L-theanine, an amino acid that promotes relaxation and improves focus and mood.

Unique benefits of green and black tea

Green tea is rich in epigallocatechin-3-gallate (EGCG), a powerful antioxidant linked to anticancer properties, neurological improvements, liver protection, and anti-inflammatory effects.

Additionally, green tea contains slightly more L-theanine, which contributes to its calming effect.

Meanwhile, black tea contains theaflavins, antioxidants formed during oxidation. These compounds may protect fat cells from damage and offer health benefits such as reducing obesity, lowering lipid levels, and supporting gut health.

Conclusion

The choice between green and black tea ultimately comes down to personal preference. Both offer substantial health benefits, particularly for heart and brain health. Green tea generally has higher antioxidant capacities and contains more L-theanine, which can be calming. Black tea, on the other hand, offers more caffeine, making it a better option for those looking for a mild energy boost without the intensity of coffee.
