About six years ago I noticed that my nails looked dirty, smudged, and had vertical ridges. This was after going to the hospital for heart problems. Doctors couldn't tell me why my nails looked like this. (And I do have rheumatoid arthritis, too.)
Two years ago I started with NT and, although not truly 100% dedicated to it, I do primarily make my own bone broths, make crispy nuts, eat good meat, drink raw milk and kefir, etc. These last few months the worst of the ridges on my thumbnail, which looked as if dirt has gotten smushed into it, has been decreasing as the nail has grown out. The black is only on the top half of the nail, not on the newest grow out. I am so excited about this.
Somewhere along the way a nutritionist said in an offhand way, "Oh, that is malabsorption." That was my lightbulb moment and what led me to Sally Fallon and beyond. Although some of you don't like Fallon, she was the beginning of a wonderful journey for me!
