Supplements Question: Soy protein and test level
(If this can be moved to the supplements forum that would be great!)
I have one big question that’s been on the back of my mind for a while now, would consuming soy protein isolate (from protein bars, cereals, etc) lower the amount of testosterone in your body?
I read in a study that for men, consumption of soy products can lower testosterone levels to below normal. Now, I personally love my high testosterone levels and don’t want to screw them up by eating the wrong things. Could anyone tell me if soy protein isolate would lower testosterone levels? As it is you find soy in everything these days, and I’d say I consume about 50-75g of soy protein per day.
Here are some sources that are FOR soy protein lowering testosterone levels:

Edit: I just checked the ingredients label on my whey protein, even that stuff has soy products! Is there anything out there without soy in it!
