That's just it, everything consumable in larger amounts needed by the body can be a poison. If you are experiencing sides from bo or anything you are taking, you should abstain. Every person is different in how they metabolize these substances. Sp can indeed be one persons poison and another's nourishment.

I do fine on sp long term, just get cellulite if taken too much.

So you don't have any scientific explanation. I think since BO will bring down FSH/LH it will induce infertility. There is scientific basis what I am saying here
