Green Tea and Bone Density

  • The catechin compounds in green tea have recently been shown to increase bone density in animal studies.
  • Previously, we saw that tea drinkers had 2.8% higher bone density than non-tea drinkers in a large human observation study, as published in the American Journal of Clinical Nutrition in 2007.
  • The study published in the Journal of Agricultural and Food Chemistry (2009) showed that epigallocatechin (EGC), a catechin compound in green tea (and one of the antioxidant components), had the strongest effect of stimulating bone growth (osteoblastic activity) and inhibiting bone breakdown (osteoclastic activity).
  • Other studies have shown an association between green tea and a reduced risk of certain cancers and heart disease and that green tea catechins can promote weight loss. As such, many health experts suggest drinking 2-5 cups per day of green tea daily for general health support.
  • It has been proposed that catechins in green tea help to burn fat by increasing thermogenesis (burning more calories at rest by prompting a person’s brown fat to burn more fat at rest and give it off as heat to the environment) and/or by releasing fat from fat cells, so muscles can burn the fat more efficiently during activity and exercise.
  • In green tea 30-40% of the constituents are antioxidant polyphenolic compounds, including various catechins
  • In black tea, only 3-10% of the constituents are antioxidant polyphenolic compounds, including various catechins (black tea is green tea that has undergone fermentation, which removes much of the catechins and other antioxidants)
  • The take home message is that drinking more green tea may be one more way that you can support your bone density and help to prevent osteoporosis, which is estimated to affect one in four women and one in eight men over 50. Of course, the anti-cancer, anti-heart disease and fat-burning properties of green tea are also very nice side effects.
  • Thus, you may wish to consider drinking 2-3 cups per day of green tea.
  • As well, remember that Adeeva Body Burn contains 200 mg of decaffeinated green tea extract per capsules (along with other fat-metabolizing agents), of which a high percentage is comprised of catechins. Taking 3 capsules per day (the recommended dosage) provides 600 mg of these important health-promoting compounds, at the same time as they assist you in achieving your weight management goals. And now we learn that these same catechins may also help to support bone density - NICE
