Superoxide Dismutase (Sod)
Has anyone had experience with taking supplements that increase SOD? I was talking to a biologist yesterday who swears that it has powerful anti-aging properties. He cited some animal studies where the lab animals lived twice as long when they had increased levels of Superoxide Dismutase.
I vaguely remember learning about it in medical school, but that's about the extent of my knowledge. He told me that the supplement he takes is called "Cell Guard" from Bio Tec Foods (on Amazon). Says he takes 3 tabs per day.
I was hoping someone here had tried it, or had some knowledge they could share.
