EGCG, or epigallocatechin gallate, is a green tea extract that is beneficial to health. It is a powerful antioxidant that has many benefits, including weight loss, cancer prevention, and heart disease protection. It is mainly extracted from green tea leaves and comes in different types based on concentration and purity.
Powdered EGCG
One of the most common forms of EGCG is green tea extract powder, usually found in supplement stores. It can be added to smoothies, protein shakes, and other foods. When buying bulk green tea extract powder, it's crucial to check the purity and concentration levels to ensure product consistency in health benefits.
Liquid EGCG
Liquid green tea extract is more potent and is recommended to be taken before workouts. It typically contains highest EGCG concentration per serving. Suppliers should focus on amber glass bottles that protect liquid extracts from light exposure, which could reduce its potency.
EGCG capsules
Capsules and pills are the most popular forms of green tea extract in the market because of easy consumption and dosage. This form is convenient and can be stocked in pills or capsules. When opting for capsules, buyers should stock extracts standardized to a certain percentage of EGCG, like 50%. Suppliers can offer options with varying EGCG concentrations to cater to different customers' needs.
Organic EGCG
For customers who value organic products, green tea extract is available in organic forms. It is extracted from organically grown green tea leaves and does not contain any chemicals or pesticides. It usually comes in powdered form or capsules. Look for certifications like USDA Organic to verify the product's organic status.
Several key specifications determine the quality and effectiveness of green tea extract.
Purity
Purest form of EGCG is typically found in organic green tea extract powder. This ensures that no fillers or additives dilute the product's effectiveness. When purchasing in bulk, always request a Certificate of Analysis (COA) from the supplier to confirm the extract's purity.
EGCG concentration
It is mainly renowned for its weight loss and health benefits, primarily due to EGCG. Choose extracts with high EGCG concentration. The potency of green tea extract is mainly dependent on the concentration or amount of epigallocatechin in catechins. For example, extracts containing 50% to 98% EGCG are considered highly potent.
Capsule vs powder EGCG
For customers who prefer easy use and fight in metabolism, capsule supplements are the way to go. Green tea extract capsules are usually available in different concentrations, often ranging from 500mg to 750mg per capsule. For those who prefer flexible dosing, green tea extract powder is the better option. It allows users to adjust the dosage as needed, which can be particularly useful for those who want to customize their intake. When purchasing in bulk, buyers can choose either capsules or powder based on their business needs and target customers. Capsules offer convenience, while powder provides versatility in dosage.
Organic certification
To cater to consumers who prioritize organic products, look for green tea extracts certified as organic. These extracts come from tea leaves grown without synthetic pesticides or fertilizers. This information is typically stated on the product label. Products with certifications like USDA Organic or EU Organic are more attractive to consumers in Western markets.
Green tea extract is beneficial in multiple ways but needs to be taken in concentrated formats.
Naturally occurring EGCG
EGCG is naturally found in green tea. One cup of brewed green tea contains about 200 milligrams of catechins, with EGCG making up a significant portion. This translates to approximately 30 to 100 milligrams of EGCG per cup. The amount varies based on factors such as tea type, brewing time, and water temperature. For consistent EGCG intake, a supplement or concentrated form is recommended.
Supplemental EGCG
Green tea extract supplements are typically standardized to contain a specific percentage of EGCG, ranging from 50 to 98%. This makes it easy to know exactly how much EGCG is being consumed. Supplements are often more potent than brewed tea, providing a higher, more consistent EGCG dose. This is especially beneficial for those seeking specific health benefits like weight management or improved heart health. Supplements are the most effective way to consume catechins in green tea daily.
Green tea extract is a highly stable supplement, and there are a few maintenance tips to remember to ensure it remains effective.
Shelf life
It is quite stable and has a shelf life of 2 years. Factors like light, moisture, heat, and air exposure can degrade its potency over time.
Storage conditions
Avoid storing green tea extract in bathrooms or kitchens, where humidity and fluctuating temperatures can reduce its potency. A cool, dry pantry or a dedicated supplement cabinet is ideal. If the extract is in powder form, consider using airtight containers to prevent moisture infiltration.
EGCG refers to extracted catechins, a type of antioxidant present in green tea, and is primarily renowned for its health and wellness advantages.
Weight loss and metabolic health
EGCG enhances the body's ability to burn fat during moderate exercises like walking. This is why bulk green tea extract is popular among fitness enthusiasts. Increased metabolic rate means the body burns more calories even at rest, aiding weight management. It may also help preserve lean muscle mass during weight loss. This makes it essential in body composition.
Heart health
EGCG is effective in cardiovascular protection. It helps to lower LDL cholesterol, the harmful type that builds arterial plaques. EGCG also aids in increasing HDL cholesterol, the good kind that cleanses arteries. As such, bulk purchases of green tea extract are favored by individuals and businesses looking to promote heart health.
Enhanced cognitive function
EGCG increases brain function through mercury and decreases the risk of neurodegenerative diseases like Alzheimer's and Parkinson's. Numerous studies indicate that EGCG aids in improving memory, concentration, and overall cognitive performance. Because of these cognitive effects, green tea extract is included in supplements focused on brain health.
Anti-cancer effects
EGCG has been found to prevent the growth of cancer cells and may help reduce the risk of developing several types of cancer, including breast, prostate, and colorectal cancer. It does this by scavenging free radicals, which are unstable molecules that can damage cells and DNA. This damage is linked to cancer development. Because of its potential anti-cancer effects, it has been included in anti-aging skin products.
Blood sugar control
EGCG may help lower blood sugar levels by increasing insulin sensitivity. This makes it useful to people with diabetes or those at risk of developing the disease. It also helps to slow the absorption of sugar from foods, contributing to better blood sugar regulation. Wholesalers catering to the diabetic market can offer green tea extract to help manage blood sugar levels.
Here are some key factors to consider when choosing green tea extract to stock or consume.
Purity and quality
To realize the full benefits of green tea, buyers should look for pure extracts, mostly in organic green tea extract powder. Extracts typically contain no fillers, additives, or artificial substances. To enhance its quality, choose extracts derived from whole green tea leaves instead of sencha.
EGCG concentration
Choose extracts containing at least 50% EGCG. Those with greater concentrations are more potent and beneficial for health. Extracts with high catechin concentration offer more antioxidant benefits.
Brand reputation
Buyers should consider stocking products from reputed brands with publicly available customer reviews. These brands usually disclose the source of their green tea and the extraction methods used. This information ensures that the extract is of high quality and pure.
Form of extract
Green tea extract is available in various forms, such as capsules, powder, and liquid. Each form has its own benefits and downsides. Capsules are convenient and easy to take, making them a popular choice for those who want a quick, no-fuss supplement. Liquid extracts are more potent and are usually recommended for people looking to quickly gain all the benefits from green tea. Green tea extract powder is often added to foods and drinks. This allows users to adjust the dosage as needed. Buyers should select the extract form based on their personal needs and preferences.
Taste and formulation
For those who add green tea to foods and drinks, the extract's flavor is crucial, especially when adding it to smoothies and juices. If buyers intend to blend the extract into food items, go for products that are flavorless or have a mild taste, like matcha green tea powder. Weak flavored extracts ensure that the green tea does not overpower other ingredients.
