I work in nephrology and we frequently encounter body builders both male and female who have rhadbdo.
I always caution my patients against using the protein supplements because yes, they can be deadly
She actually died of uric cycle disorder, which is a genetic disorder that affects normal protein metabolism. This could have occurred regardless of the source of her protein intake, a serving of protein supplement marketed to bodybuilders is effectively no different than eating a steak or having a couple of Ensures. I would agree that other supplements marketed to bodybuilders should be better regulated, but I don't think it's really feasible or beneficial to regulate protein.
