Bromelain helps with implantation?

So I was reading through a few forums on babycenter and they mentioned that eating the core of a pineapple, or simply taking 1 tab of 500 mg of bromelain for 5 days would help with implantation. The core of the pineapple because it's high in bromelain. They also say it's important not to eat it before you ovulate because it can make you too acidic, but it you take it after ovulation 1-7 dpo (not more than 7dpo) than you increase your chances of having successful implantation and getting a bfp. Has anybody heard about this? Does anybody have more information on it?
