Camellia Sinensis (Green Tea)

Camellia Sinensis (Green Tea)

Derived from the Camellia sinensis plant, green tea extract is highly valued in the wellness world for its numerous health benefits. As we journey through the intricacies of this natural extract, you will discover the science behind its functions, benefits, types, and dosage.


What is Camellia sinensis Leaf Extract?

Camellia sinensis is the botanical source of various tea varieties, including black, green, white, and oolong teas. Notably, green tea is cherished for its health-promoting properties, attributed to a unique preparation process that ensures the retention of its beneficial compounds. These properties are expertly harnessed in the 'Super 23' supplement for maximal health benefits.

Green tea, prepared from unfermented leaves, is a powerhouse of bioactive compounds. Its leaves are brimming with flavonoids and catechins, types of polyphenols acting as potent antioxidants that guard the body against harmful free radicals and inflammatory mediators (1).


What does Camellia sinensis do?

For centuries, Camellia sinensis or green tea has been steeped not only in hot water but also in the history of traditional medicine, renowned for enhancing metabolism and energy levels. Current research supports its long-standing reputation, attributing the following health benefits:

Boosts Metabolism:

Among the key benefits of Camellia sinensis is its metabolic-enhancing properties. Polyphenols, specifically Epigallocatechin gallate (EGCG), help accelerate metabolism, promoting fat oxidation and contributing to weight management. Incorporating green tea into your daily regimen is an effective, natural way to boost metabolism.

Supporting Energy Levels:

Green tea contains a small quantity of caffeine, which helps initiate your body's energy production pathway. Unlike caffeine from other sources, which may result in energy crashes and jitters, caffeine from green tea is generally safe and gentle on the body. Adding green tea to your diet can help keep you alert, focused, and energised throughout the day (2).

Promoting Mental Focus:

The presence of L-theanine and caffeine in Camellia sinensis can improve cognition and focus. L-theanine has calming effects on mental health. Together with caffeine, it helps to enhance mental clarity and prevent brain fog. This natural combination of ingredients promotes focus, improves concentration, and supports overall mental health (3).


Protects Body from Inflammation:

Camellia sinensis is packed with natural antioxidants, offering protection against oxidative stress. The body naturally produces free radicals through various metabolic processes, which can cause inflammation and damage to different organs. Acting as a natural antioxidant, Camellia sinensis neutralises these free radicals, helping to prevent unwanted inflammation (2).


Helps Shed Extra Weight:

By naturally enhancing metabolism, Camellia sinensis can assist in shedding stubborn body fat (4). A sluggish metabolic rate can lead to obesity, and green tea gently increases this rate to support a healthy weight. Including green tea in your daily routine can supplement your weight management efforts, meaning you won't have to spend countless hours in the gym.

 

How does Camellia sinensis work?

The remarkable health benefits of Camellia sinensis are primarily attributed to its bioactive compounds, which work synergistically to promote well-being. This tea's antioxidative properties scavenge free radicals in the body, which might otherwise cause cellular damage and oxidative stress. Its catechins, particularly EGCG, have anti-inflammatory properties and are even associated with anti-cancerous effects, potentially eliminating cancer-causing microorganisms (5).

Camellia sinensis' caffeine content enhances alertness, focus, and physical performance by stimulating the central nervous system. Together with caffeine, L-theanine contributes to improved mental clarity, cognitive function, and a calmer state of mind (6).

Known for its metabolic-boosting benefits, Camellia sinensis promotes efficient energy usage in the body, making it a safe and effective way to shed those extra kilos. It capitalises on existing energy sources and accelerates fat mobilisation for energy synthesis.

 

Types of Camellia sinensis?

Derived from the Camellia sinensis plant, various tea varieties each offers a unique blend of healthful components (7):

 

Green Tea:

Produced from the unfermented fresh leaves of the Camellia sinensis plant, green tea is recognised for its grassy flavour and bright green colour. It's a rich source of antioxidants, making it an excellent choice for those with weakened immune systems.

 

Black Tea:

Black tea results from the complete fermentation of Camellia sinensis leaves, during which the grassy flavour transforms into a robust one. While black tea still contains abundant antioxidants, some are lost during fermentation, giving green tea a slight advantage in terms of antioxidant content.

 

White Tea:

The least processed of all, white tea consists of young leaves and buds. Minimal oxidation occurs during its production, ensuring it retains the maximum amount of antioxidants.

 

Oolong Tea:

Oolong tea strikes a balance between black and green tea, achieved through partial oxidation of the leaves. This results in a variety of flavours and a unique aroma.

 

Dosage Guidelines

The appropriate dosage of Camellia sinensis varies based on factors like age, health status, and individual sensitivity. Generally, a safe and beneficial dose is 2-3 cups per day, taken at regular intervals (1).

Consider your health and sensitivity when consuming green tea. Those with underlying medical conditions may experience side effects if consumed in high doses. Pregnant women should seek advice from their healthcare professional for tailored recommendations.

 

Best time to take Camellia sinensis?

The optimal time to consume green tea largely depends on individual preferences and health goals. Some might favour it in the morning before breakfast to kick-start their metabolism, while others might prefer it post-meal or at various times during the day. Green tea can be enjoyed at any time, whether on an empty stomach or after food, and it will provide the same benefits (8).

However, keep in mind that green tea contains a small amount of caffeine, which might interfere with your sleep if consumed before bedtime. If you desire a cup in the evening, consider caffeine-free herbal teas such as chamomile or peppermint. Avoid consuming a high dose of green tea (2-3 cups) at once, as it may lead to anxiety or hyperactivity. To ensure it doesn't affect your physical or mental health, spread your intake throughout the day.

 

Potential Side-effects of Camellia Sinensis

While generally safe when consumed in moderation, excessive intake of green tea could lead to caffeine-related side effects and digestive issues. It may interact with certain medications, potentially causing complications. Rarely, high consumption of green tea extracts may even result in liver toxicity. Therefore, it's important to use caution, consume green tea in moderation, and seek professional advice when needed.

 

How to Enjoy Camellia sinensis?

Camellia sinensis can be savoured in numerous ways depending on personal preference. Here are some enjoyable options for consuming this health-boosting plant:

 

Traditional Brew:

Simply steep green tea bags or loose green tea leaves in hot water for 2-3 minutes and enjoy your freshly prepared green tea.

Iced Green Tea: 

For a chilled version, brew a concentrated batch of green tea and pour it over ice. Add a splash of honey or a squeeze of lemon for an extra flavour boost. 



Matcha Green Tea:

Matcha, the powdered form of green tea, allows you to consume the entire tea leaf. Combine the matcha powder with hot water and whisk it into a vibrant, frothy green drink. 

Green Tea Smoothie:

Blend your favourite fruits, leafy greens, and yogurt with green tea to create a nutritious and delicious smoothie. By adding different fruits, you can enjoy a unique taste experience each time. 

Green Tea Extract Supplements:

If incorporating green tea into your diet proves challenging, consider capsules or liquids in supplement form. Always adhere to the recommended dose from healthcare professionals and manufacturers to avoid potential side effects.  

 

Final Verdict

Camellia sinensis leaf extract, or green tea, is a natural wellspring of antioxidants and other health-boosting compounds. Incorporating green tea into your daily routine can contribute to an invigorated sense of well-being, enhancing metabolism, energy levels, and mental focus. Thanks to its ability to accelerate metabolic processes, it's one of the best natural supplements and an organic solution for individuals looking to lose extra weight. With an array of Camellia sinensis varieties and preparation methods to choose from, you can select one that matches your preference and palate.
