Brother Sam... Please share the types and brands of collagen (powder I presume?) that you prefer.Interesting experiences. I've tried lots of supplements, and haven't noticed a difference from using any of them - except one.
Collagen or Bone Broth (same thing).
Had a nasty shoulder injury that would not heal for four months, and my girl recommended to me to use Bone Broth. I tried it, and it healed within 2 weeks!
Saw an old man at a Parish I infrequently attend, who would walk around with a cane barely able to move and could hardly get out of his seat. I told him to try bone broth. Next time I saw him a few months later, I asked him how he was and he said (in a thick British accent) "Nevvverrr felt better!!" and he's zooming around without any cane! He now serves in the Altar with the other Altar boys!
My father couldn't get out of bed in the morning, his arthritis was so severe. Got him on a collagen mix, and within 3 weeks all his pain went away and he is able to lift heavy gallons of paint like it's nothing!
Never seen any other supplements have such a fast effect on health. Collagen is basically grease for the joints. It's dirt cheap too. I surmise that back in the old days, Grandma would cook soup by throwing the bone into the soup. That's how people used to get their collagen. Nowadays most diets don't have this sort of thing, so supplements are extremely helpful.
I notice if I use collagen supplements I can lift heavy at the gym with barely a creak in my bones. But without collagen supplements, my knees pop like fireworks. The stuff is for real.
