Green Tea

Green tea is one of the most popular beverages in the world. It is a staple in many cultures, especially in Asia, where it has been consumed for centuries for its health benefits and cultural significance.^[1] Globally, tea ranks as the second most consumed beverage after water.^[2]

What are the benefits of green tea? Green tea provides antioxidants that support cellular health, moderate caffeine for steady energy and L-theanine for calm focus.^[3] These compounds make green tea unique, offering both physical and mental benefits.

When deciding between matcha and green tea, factors like caffeine content and preparation methods play an important role. Whether you prefer loose leaf green tea or tea bags can also impact flavor and nutrient levels. And finally, the timing of your green tea intake, such as before bed or during the day, may influence its effects. This guide delves into green tea caffeine content, its health benefits and how to choose the best option for your needs.

Green tea comes from the Camellia sinensis plant, the same source as black and oolong teas. What makes green tea special is its minimal processing. The leaves are quickly steamed or pan-fired to preserve their natural compounds, including antioxidants like catechins.^[4] This method gives green tea its light, fresh flavor.

Green tea isn’t just a comforting drink; it offers powerful health benefits backed by science. Researchers continue to explore how green tea and its compounds support physical performance, stress management and wellbeing.

A recent study found that matcha green tea may support muscle adaptation during resistance training.^[9] Participants who consumed matcha drinks twice daily showed greater increases in leg strength and muscle mass compared to a placebo group. Matcha intake also helped with exercise-related fatigue and stress, with participants testing for lower salivary cortisol levels. Changes in gut microbiota linked to matcha consumption correlated with better muscle strength, suggesting a connection between gut health and training adaptation.

In another study, researchers evaluated a supplement combining magnesium, vitamins B6, B9, and B12, rhodiola, and green tea/L-theanine (Mg-Teadiola) for its effects on stress.^[10] Over 28 days, participants taking Mg-Teadiola experienced significant lower stress scores compared to a placebo group, with changes being sustained at 14, 28, and 56 days. The supplement also helped with sensitivity to cold pain and promoted sleep quality. These findings suggest that green tea compounds like L-theanine, when paired with other nutrients, can support stress management and overall well-being.

And finally, a study looked at how the green-Mediterranean (green-MED) diet, which includes green tea, Mankai, and walnuts while limiting red and processed meat, affects non-alcoholic fatty liver disease (NAFLD).^[11] Over 18 months, people on the green-MED diet showed improvements in fatty liver levels nearly twice as much as those on a standard Mediterranean diet or following general healthy eating advice. NAFLD rates were also lower overall for those in the green-MED group. The diet helped to promote health markers like folate levels and gut bacteria balance, showing that adding more plants and polyphenols can help support liver health and manage NAFLD.

These studies reveal green tea’s versatility, from promoting physical performance to supporting stress levels and liver health. In the next section, we’ll explore the Bulletproof approach to incorporating green tea into your routine for maximum benefits.

At Bulletproof, we take green tea seriously, focusing on the science and benefits behind every ingredient we use. Our approach ensures you get the most out of green tea, whether it’s through targeted supplements or recipes like the Bulletproof matcha latte, a delicious way to integrate green tea into your daily routine.

Spotlight on Green Tea

When it comes to green tea, quality matters. That’s why we select ingredients for their purity, potency and bioavailability. Green tea is a natural source of antioxidants, including EGCG, which supports cellular health and helps fight oxidative stress. We use these compounds in products like Greens and Superfood Antioxidants to deliver targeted benefits.

Our approach highlights green tea’s naturally occurring L-theanine, a key amino acid that promotes calm focus. When paired with the caffeine in green tea, L-theanine supports steady energy without the jittery feeling you might get from coffee. This natural combination makes green tea an excellent choice for staying productive and focused throughout the day.

We also look at synergistic plant compounds. Polyphenols from green tea, combined with antioxidants from other superfoods like berries and herbs, amplify the benefits for your body.^[12] This synergy supports brain function, gut health and healthy aging. Each product is designed to fit into your routine seamlessly, so you can fuel your body and mind without extra effort.

Finally, we focus on sustainability. By sourcing high-quality, ethically produced green tea, we support both your health and the environment. With the Bulletproof approach, you can trust that every ingredient works hard to support your goals, from better energy and focus to overall wellness.

To ensure our products deliver on their promises, we go beyond sourcing and apply rigorous testing standards to every supplement we create.

Our Supplement Testing Standards

At Bulletproof, we prioritize scientific accuracy and quality in every step of our supplement production process. We select ingredients backed by research published in peer-reviewed journals and test them for efficacy using proven methods. Each supplement undergoes rigorous testing to meet FDA standards for identity, purity, strength and composition. We analyze each production lot for its physical and chemical properties to ensure consistent quality. In addition, we collaborate with accredited third-party labs to validate that active ingredients are present at effective levels, ensuring our products deliver the results you expect while maintaining safety and integrity.

To guarantee safety and quality, our supplements go through a four-layer testing process. We begin with identity testing to verify that all ingredients are authentic and undiluted. Next, we test for purity to confirm the product is free from harmful contaminants. Strength testing ensures the active ingredients meet the dosages listed on the label, while composition testing confirms the product aligns with its specifications. Beyond external evaluations, our internal food safety experts conduct ingredient risk assessments, focusing on the well-being of our customers.
