CLA is a very popular supplement for a variety of health and bodybuilding reasons. There is yet another reason to take CLA now, for its anti-estrogen properties. A group of researchers in Georgia grew breast cancer cells in a lab. When CLA was introduced it interfered with the estrogen signaling in the cells due to it’s direct anti-estrogen activity. This is good for not only all females, but any male who uses steroids. CLA is touted for it’s body recomposition benefits mainly as a result of insuline sensitivity. It makes me wonder how much of it is actually instead, due to the anti-estrogen effect in CLA?
