This is turning out to be a case of a little is important, but a lot is detrimental. While whey protein is supported by many studies about adding protein for seniors, and I've given my cats collagen because they aren't out there licking bones, a person who eats enough animal foods probably shouldn't worry about collagen.

Large amounts seem to angry up the immune system. One of the mistakes I made. Which is why I am looking twice at all supplements and isolated components of our food.

The more I craft a proper diet, the less of such "helps" I need. And plant-based collagens are similarly artificial creatures of the vegan world.

"Pork-based proteins" is a can of Spam.
