What You'll Learn
Green tea diet pills may cause side effects
Some studies have found modest reductions in body weight associated with green tea supplementation. For example, a 2020 review found that consuming at least 500 milligrams (mg) of green tea extract daily for 12 weeks helped reduce body weight and BMI. However, other human trials have found no benefit, and the authors of an NIH fact sheet concluded that if green tea is an effective weight-loss aid, the effect is small and not likely to be clinically relevant.
Furthermore, experts warn against taking the large amounts used in many studies and recommended on supplement labels. There have been reports of serious liver damage in people who used green tea supplements. One study published in 2017 found that postmenopausal women who had taken green tea extract twice a day for a year as part of a breast cancer clinical trial had elevated liver enzymes, a sign of potential liver damage.
In addition to potential liver damage, green tea diet pills may also cause other side effects. For example, some people may experience stomach pains, cramps, nausea, and breakouts after taking green tea pills. Additionally, the pills are quite large in size, which may be a concern for some individuals.
It is important to speak with a healthcare professional before taking any dietary supplements, as they can help develop a safe and effective plan for weight loss that is tailored to your individual needs.

Green tea's weight loss properties
Green tea has been consumed for thousands of years for its potential medicinal benefits, such as boosting digestion and alertness. It is considered one of the healthiest drinks on the planet due to its high antioxidant content and various plant compounds.
Tea leaves contain beneficial plant compounds that could help prevent chronic conditions like diabetes and obesity by fighting inflammation and oxidative stress and lowering cholesterol and insulin levels. Green tea contains catechins and caffeine, which may promote weight loss by increasing daily calorie burn (energy expenditure), boosting fat oxidation, metabolism, and thermogenesis. The most important catechin in green tea is epigallocatechin gallate (EGCG), which makes up to 80% of its catechins. EGCG could aid fat oxidation and lipolysis by boosting the effects of fat-burning hormones like catecholamine.
Research on the effects of green tea on weight loss is mixed. Some studies have found modest reductions in body weight associated with green tea supplementation, while other human trials have found no benefit. A 2020 review found that consuming at least 500 milligrams (mg) of green tea extract daily for 12 weeks helped reduce body weight and BMI. However, the weight loss effects of drinking green tea after 2 weeks are likely negligible. Most studies examining the effects of green tea for weight loss have lasted at least 6 weeks.
Drinking 2-3 cups of green tea can help with weight loss, but it is important to note that green tea or its supplements will not lead to weight loss alone. Maintaining a calorie deficit is crucial for weight loss, which means consuming fewer calories than you burn during the day. Green tea might aid in achieving a calorie deficit when paired with other factors such as a balanced diet and regular exercise.

Green tea's health benefits
Green tea has been consumed for centuries and is known for its health properties. It is rich in bioactive substances and antioxidants, which can improve the function of your body and brain. It is also said to have anti-inflammatory properties. Here are some of the potential health benefits of drinking green tea:
Weight Loss
Green tea contains substances that may promote weight loss by increasing the number of calories burned daily and boosting fat oxidation, metabolism, and thermogenesis. However, the research on the effects of green tea on weight loss is mixed, and drinking green tea alone will not lead to weight loss. It is important to maintain a calorie deficit and a healthy diet and exercise regimen to effectively lose weight.
Lower Risk of Chronic Conditions
The antioxidants in green tea can help prevent or remedy cellular damage, reduce inflammation, and lower cholesterol and insulin levels, which may help prevent chronic conditions like diabetes, obesity, heart disease, and certain types of cancer.
Improved Brain Function
Green tea may benefit cognition, mood, and brain function, possibly due to compounds like caffeine and L-theanine. A 2020 study suggested that green tea is linked to a 64% lower chance of cognitive impairment in middle-aged and older adults.
Skin Health
Non-human studies have found that polyphenols in green tea increase collagen and elasticity in the skin, helping to combat wrinkles and other signs of aging. Green tea extract has also been found to help prevent acne and spot-treat pimples.
Other Benefits
Green tea may also help reduce anxiety, keep bones healthy, and boost digestion and alertness. It is important to note that while green tea has many potential health benefits, it should be consumed as part of a balanced diet and not relied upon as a sole solution for weight loss or disease prevention.

Green tea extract pills vs. tea
Green tea is a popular beverage that has been consumed for thousands of years for its potential medicinal benefits, such as boosting digestion, alertness, and fat burning. It is also said to have anti-inflammatory, antioxidative, and anticancer effects. The most important catechin in green tea is epigallocatechin gallate (EGCG), which accounts for up to 80% of green tea's catechins and provides numerous health benefits.
Green tea extract is the concentrated form of green tea, with one capsule containing the same amount of active ingredients as a cup of green tea. It is a common ingredient in weight-loss pills and supplements, with consumers spending approximately $141 million on these supplements in 2020. Green tea extract pills are regulated as foods, not medicines, and specific safety testing is not required.
Research has shown that green tea extract can be effective for short-term weight loss. A 2020 review found that consuming at least 500 milligrams of green tea extract daily for 12 weeks helped reduce body weight and BMI. However, it is important to note that green tea extract can also be toxic when taken in excess, and side effects can negate the benefits. High concentrations of catechins and caffeine in green tea extract have been shown to be harmful, and there have been reports of serious liver damage in people who consumed green tea supplements.
On the other hand, drinking a few cups of brewed green tea is considered a healthy habit and can be a good replacement for sugary drinks. Consumption of up to eight cups a day is believed to be safe, although it is recommended that pregnant or breastfeeding individuals limit their intake to six cups per day. Drinking green tea or taking green tea extract supplements will not lead to weight loss alone, and it is important to maintain a calorie deficit for effective weight loss.
In conclusion, while green tea extract pills may be effective for short-term weight loss, they can also pose health risks when consumed in high doses or in combination with certain medications. It is generally safer to consume green tea in its natural form, and maintaining a healthy diet and lifestyle is more beneficial for sustainable weight loss.

However, other customers have reported negative side effects, including high blood pressure, heart palpitations, and stress. One customer reported feeling faint, hot, and nauseous after taking the second dose. Another customer mentioned that the pills are quite large and require a lot of water to consume.
It is important to note that green tea contains caffeine, and consuming large amounts of caffeine can have side effects such as jitteriness, headache, and fast heartbeat. Additionally, drinking more than 8 cups of green tea daily is considered possibly unsafe due to the caffeine content.
Consulting with a healthcare professional before taking any dietary supplement is always recommended, especially for individuals with existing health conditions or those taking medications.
