CLA and Estrogen

CLA has long been used as a bodybuilding supplement in order to facilitate in fat loss. Research has demonstrated that it is also very effective at blocking estrogen signalling in the human breast cancer cells. A series of in-vitro tests conducted by researches in Georgia, has shown that in the presence of cancer cells, CLA has direct anti-estrogenic activity and can, therefore, interfere with estrogen signalling in breast cancer cells. This may be good news for bodybuilders who suffer from gynocomastia, or who are using prescritption anabolics. Not only can CLA help facilitate fat loss, it may also work against estrogen, and help keep you in an anabolic state.
