Collagen can be obtained exclusively from animal sources.
Bones, head, cartilage, usually from cows and pigs. If all of this appeared on the labels of supplements sold, people would think twice before buying them.
Wait, don't get ahead of yourself. You might be thinking that marine collagen exists, which sounds great (kudos to the marketing team at those companies), but the reality is very different.
It is obtained from the fins and bones of fish, often through practices that are not very ethical or respectful of animals.
But what if there was a way to obtain collagen in a more sustainable way?
There is, and it can be obtained from a source that would otherwise simply be food waste.
I'm talking to you about collagen from the eggshell membrane.
Have you ever noticed when hard-boiled an egg that once you remove the shell, it's tightly attached to a skin-like membrane? This membrane is especially rich in collagen, hyaluronic acid, and elastin.
