Nan Optipro Gold VS Nan Optipro Gold HA

Wondering what the benefits are of HA formula compared to the normal?

My MIL accidentally bought 2 tins of the HA formula and I am unable to return it to the store without proof of purchase (she had already thrown out the receipt) so I’m stuck with 2 tins of formula I can’t use.

From what I understand, the HA formula could actually be better for him so I have considered it prior to the tins even being purchased. I’ve called the hotline for nestle and they weren’t much help other than telling me the breakdown of ingredients 🤷🏽‍♀️ Our two doctors are on holidays at the moment so a bit stuck for help.

Any thoughts?
