Brainfogged indeed. The types of collagen are quite different. Also, not all reputed sources of type II collagen are that. Some are just types one and three which are cheaper. The brand I recommended is authentic at this time.
I tried astanthanthin but it didn't do anything for me. I'm glad it worked for you.
When I tried glucosamine and chondroitin years ago they didn't work for me. Recently I tried Cosamins which supposedly contain those things extracted from shellfish shells. It just causes joint pain.
Chicken cartilage Type II collagen naturally contains glucosamin, chondroitin and collagen which I find to be assimilable.
The key with nutrients is what is right for that person and what that person can assimilate. Maybe crab shells do contain glucosamin, but most people can't metabolize it in that form. MSM and collagen are frequently sold in pill form, but I feel they are only assimilated well in liquid solutions, preferably along with vitamin C.
One reason to take type II collagen is that our diet is deficient in those nutrients. Think about it, we eat only the muscle meats and throw half the animal away. Our muscles are relatively well-nourished but as people get older they develop problems with precisely the parts of the body we do not eat in animals; joints, cartilage, connective tissue, skin, eyes. Native peoples eat all of the animal. Traditional western cultures also utilized more of the animal such as calves foot jelly, soup stock made from bones and cartilage, bone marrow, organ meats, blood sausage.
MSM is also a good one because it is currently deficient in the soil and because our produce travels such a long way that this nutrient is gone by the time you eat it. If you take it properly you will have the best chance to see if it helps you.
Other than that, I would say that those injections you spoke about sound like a bad idea. Remember to eat well. Try to stay natural, and beware of megadoses. They can just put a strain on your body.
