Does Green Tea Extract Help with PCOS?
As someone who has PCOS, have you had a refreshing glass of iced green tea lately? Or green tea extract? Based on our review of medical research, you may want to give it a try.
Green tea extracts are among the most widely used ancient medicinal agents, especially in traditional Chinese medicine.
We have 60 medical studies on file regarding green tea. Most of them show that green tea and green tea extract will promote your health -- and may also help you to reduce symptoms of polycystic ovary syndrome. On this page are just a few examples of what we've discovered about green tea extract in these studies.
You can find green tea extract in these high-quality products:
- OvaBlend, a formula designed to support healthy ovarian function, has green tea extract in it.
- PureLean Green Coffee is a powdered drink that contains both green tea extract and green coffee extract.
Weight and Body Mass Index. Oklahoma State University reported on 35 overweight people with metabolic syndrome (similar to PCOS). They were divided into 3 groups: water only, green tea, or green tea extract. After 8 weeks, the folks either drinking green tea to taking green tea extract had decreases in body weight and improvements in their body mass index.
A study at Provident Clinical Research in Indiana evaluated overweight individuals who were put on an exercise program. Some received special green tea beverage while others did not. Those who consumed the green tea had a greater loss of belly fat.
A Chinese study of obese women with PCOS showed that consumption of modest levels of green tea extract resulting in slight weight loss and slight improvement in menstrual cycle. However, the amount of green tea in this study may have been too low to have maximum effect. Another study showed weight loss and reduced waist circumference in people who were moderately overweight.
Acne. The University of Miami reported that green tea extract applied topically twice daily for six weeks, resulted in a 58% reduction in acne in twenty people.
Fatty Liver Degeneration. Up to 50% of women with PCOS may have some degree of fatty liver degeneration, a disease that makes many things go wrong in your body. Rutgers University reported that green tea reduced fat accumulation in the livers of mice.
Oxygen Capacity. Colorado State University showed that people taking green tea extract had increased maximal oxygen uptake (VO2max) compared to those taking a placebo. VO2 max is the maximum capacity of your body to transport and use oxygen, which is an indication of your physical fitness and an important determinant of overall quality of life. Maximal oxygen uptake is also a powerful predictor of maximum work capacity, endurance performance, and longevity. To the extent that green tea extract can increase VO2max, it has obvious and important implications for your health.
Appetite. Lund University in Sweden reported that people drinking green tea reported greater fullness with a meal. The people also had a less strong desire to eat their favorite food and found it less pleasant to eat another mouthful of the same food.
Androgen (male hormone). Excessive levels of androgens are a primary cause of many symptoms of PCOS, including hirsutism, hair loss, acne and infertility. Cell experiments by the University of Chicago showed that green tea extract had a dampening effect on the effects of androgens.
Hair loss. The Charles R. Drew University of Medicine and Science tested mice with spontaneous hair loss. Some were given pure water while others were given water with green tea extract. 33% of the mice drinking the tea-laden water for six months had significant hair regrowth. No regrowth occurred in the mice drinking only pure water.
Cortisol (Stress Hormone). The University Medical School Schleswig-Holstein in Germany has just reported that green tea extract blocks an enzyme that leads to cortisol production. This means that green tea extract can help to better regulate cortisol. This is important.
Cortisol is a stress hormone that builds belly fat and causes a host of other health problems. A lot of women with PCOS have cortisol levels that are too high, which is one reason for the expanded waistlines.
Cancer, Endometriosis, Uterine Fibroids. Several medical research studies have shown that consumption of green tea extract has anti-cancer activity. It also can help to reduce uterine fibroids and endometriosis.
We don't have room to review the other possible benefits of green tea, such as antioxidant activity, reduction of diabetes and heart disease risk, and reduction of cholesterol.
The data regarding green tea's ability to help you control blood sugar isn't entirely clear. Some studies say it helps you keep your blood sugar stable while one other study says it does not.
Not all the news is good. A study by the University of Calcutta in India showed that green tea or black tea extract interfered with thyroid function in male rats.
However, when you sum it all up, it appears that consuming green tea or taking a green tea extract would be a good idea for most of you, especially if you have polycystic ovary syndrome or have an issue with diabetes.
