5 Natural Remedies for Coping with the Side Effects of Chemotherapy

Please can someone tell me where I can obtain bromelain 6500 gdu? I can't find it anywhere. I can find 3000 gdu. Could I just use twice the amount of that? Or does it not work that way? I'm trying to help someone close to me who has damage from chemo. I saw Ted makes his own bromelain 10% with that and glycine.
