I buy cow feet for $1.50 a pound and make my own bone broth in the Instant Pot. I drink 2 cups a day. The gelatin is so thick and strong that I have to cut it with a knife and use a spatula to get it out so I can reheat it on the stove. I spend everyday outdoors, in the sun, rain, wind, snow (whatever) and rarely get sick ever. My hair and nails grow like weeds as well.
