Those Ingas are huge, I've only ever seen the smaller ones.
For those unaware, they are also known as ice cream beans in English, so a while ago, I filled an ice cream tub with them and announced to the kids: "Who wants ice cream?" and gave it to them. Seeing their faces was priceless, going from pure joy to math lady meme in a split second as they lifted the lid, lol
Not at all honestly, I've never seen anyone pooping their pants off after eating them. I actually got curious about it, but I was unable to find the scientific evidence of laxative effects from Malpighias
If I were to guess, all the fiber and food matrix helps slow down the absorption rate of the vit C, which prevents the laxative effects that you might have when you ingest those pills from the store
