If you’ve made a commitment to kick off the brand-new decade with focus on a healthy diet and more exercise, this blog will certainly be of interest! You’ve probably heard of green tea and know that it’s good for you, but do you know why? Altruvita’s expert nutritional team takes a look at how adding a green tea extract to your routine can deliver a range of additional benefits and what they are.
What is green tea?
Green tea is made from unoxidized tea leaves from the Camilla Sinesis bush (whereas black teas are made from totally oxidized tea leaves from various plants) and it has been enjoyed as a drink for centuries. Green tea is widely believed to have a variety of health benefits, so where do they come from? Polyphenol antioxidants called catechins comprise the majority of green tea’s antioxidant content. Among the catechins in green tea, epigallocatechin gallate (EGCG) is the most researched and thought to provide the most health benefits. All of these things are found in more concentrated doses within green tea extracts, rather than diluting these key ingredients within green tea beverages.
How do green tea and green tea extracts support our health?
Green tea helps to maintain women’s and men’s health* and it helps to reinforce the antioxidant defences of the body, including skin and eyes.* It also maintains healthy gut flora*, which means it feeds the bacteria in our gut, which in turn keeps our immune system functioning. All of these things are important at this time of year when you’re trying to look and feel better at the same time as fighting off colds and flu.
Recent green tea supplement research
If you are one of the many thousands who are kick starting their year with a regular exercise routine, with a plan to lose weight, you may be interested in some research which was published in September of last year.
Considering the relationship between cardiovascular diseases (heart disease, stroke) and obesity, the study investigated the effects of a green tea supplement and high-intensity interval training on blood cholesterol, triglycerides, maximal oxygen consumption (VO2max) and other risk factors in overweight women.
Thirty overweight women (aged 20-30), were chosen and randomly divided into three equal groups (green tea alone, or exercise + green tea, or exercise + placebo). They worked-out for 10 weeks doing 40m shuttle runs at maximum effort. Women took 500 mg per day of green tea extract or placebo tablets.
After 10 weeks, triglycerides, LDL (bad cholesterol), weight, and body fat percentage decreased in all groups. HDL (good cholesterol) and VO2max significantly increased in the exercise + green tea and exercise + placebo groups; whilst in the green tea group they did not, which would be expected without exercise.
It suggests that to get the full health benefits, a green tea extract combined with high intensity interval training exercise is probably the best way to go. Green tea and exercise both have their own unique way of improving different measurements and so collectively provide the best option.
Our carefully sourced green tea extract is low in caffeine and is composed of 98% green tea polyphenols.
