Introduction
Green tea and green tea extract both offer unique health benefits and have become popular choices for those looking to improve their well-being. Green tea, made from the young leaves of the Camellia sinensis plant, is one of the least oxidized types of tea and has a rich history rooted in China, now widely produced globally. On the other hand, green tea extract, derived from the same plant, boasts concentrated antioxidant properties and is a convenient supplement form that can significantly enhance your health regimen. We will explore the origins, health benefits, caffeine content, and L-theanine levels of both green tea and green tea extract, helping you understand how each can contribute to your health goals.
Green Tea
Green tea is one of the least-oxidized types of tea. Producers make it from young tea leaves plucked towards the end of the harvest season after the production of white, oolong, and black teas. Although green tea originated in China, it is now widely produced in nearly every tea-growing region worldwide. Some of the best green teas are now made in Japan, India, Taiwan, Kenya, and Sri Lanka.
Green Tea Extract
Researchers have created a decaffeinated green tea polyphenol mixture from Camellia sinensis, a plant native to Asia, which boasts antiviral, antioxidant, and potential cancer-preventive properties. This green tea extract contains powerful antioxidant compounds, including flavonoids, vitamins, and polyphenols like epigallocatechin-3-gallate (EGCG). These compounds may help prevent the development of cancer. By removing the caffeine, this green tea extract retains its beneficial properties while being suitable for those sensitive to caffeine. The combination of these antioxidants helps the extract combat viruses and reduce oxidative stress in the body, potentially lowering the risk of various diseases.
Health Benefits
Green Tea
Green tea has been shown to reduce the risk of heart attack and stroke by promoting healthy blood flow and reducing cholesterol levels. It can also lower blood pressure and improve the health of blood vessels. Green tea is believed to have a positive effect on brain function due to its caffeine content, which acts as a stimulant to improve alertness and concentration. However, green tea contains less caffeine than coffee, making it a milder and more sustainable source of energy. Additionally, green tea contains L-theanine, an amino acid that improves brain function by increasing alpha brain waves, leading to a feeling of simultaneous relaxation and alertness. It also aids in weight loss by increasing metabolism and reducing fat absorption from the diet, although it should not be relied upon solely for weight loss and should be combined with a healthy diet and regular exercise.
Green Tea Extract
Green tea supplements offer numerous health benefits. It increases the body’s antioxidant capacity and protects against oxidative stress. The catechins in green tea extract may help reduce blood pressure and improve blood fat levels, promoting heart health. Studies show that green tea extract has a positive effect on brain health and memory, and it may help protect against brain diseases. Green tea extract may aid weight loss by increasing the number of calories burned through thermogenesis, although the effect is modest and the responsible component—catechins or caffeine—is unclear. High doses of green tea extract can be toxic and may cause serious liver damage. Additionally, green tea extract has been shown to help maintain cell health and may even help prevent some types of cancer, though more research is needed.
Caffeine Content
Green Tea
An 8-ounce (230-ml) cup of green tea contains between 30 and 50 mg of caffeine. Therefore, the recommended maximum daily caffeine intake is 400 mg, which is equivalent to around eight cups of green tea.
Extract
While a cup of green tea contains 50–100 mg of green tea catechins and 30–40 mg of caffeine, green tea extract supplements often contain 375 mg or more of green tea catechins and up to 600 mg of caffeine.
L-Theanine Content
Studies show that L-theanine can help reduce feelings of stress and anxiety by blocking excitatory neurotransmitters like glutamate, resulting in feelings of calm and relaxation. L-theanine also stimulates GABA, a neurotransmitter that produces its own calming, anxiety-reducing effects.
Green Tea
A cup of green tea naturally contains approximately 25 mg of L-theanine. Brewing a cup of green tea releases about 25 mg of this amino acid, known for promoting relaxation and reducing stress. By drinking green tea, you can benefit from the calming effects of L-theanine, which helps improve focus and mental clarity without causing drowsiness. This makes green tea an excellent choice for those seeking a balanced, natural way to enhance their mental well-being.
Green Tea Extract
In supplements, manufacturers offer pills containing up to 500 mg of L-theanine per serving. By taking these supplements, you can significantly increase your intake of L-theanine compared to what is naturally found in a cup of green tea.
Conclusion
Green tea and green tea extract each offer a wealth of health benefits, from antioxidant and antiviral properties to heart and brain health support. Understanding the differences in their composition and benefits can help you make an informed choice about which form best suits your lifestyle and health goals. Green tea provides a balanced, natural way to enjoy these benefits daily, while green tea extract offers a concentrated dose for those looking for a convenient supplement option.
