B12 and the appearance of the fingers.
I read somewhere that large, visible half moons on the finger nails and smooth finger nails indicates good B12 levels and now I wish I had got my levels tested (although I am sceptical of the way this is measured). My nails used to have some noticeable ridges but nothing really dreadful but only the half moons on my thumbnails showed.
Since I have been living in my caravan with less opportunity to wash things thoroughly and with a huge increase in the contact I have with the soil I have noticed that the ridges are less and there are half moons visible on all my nails - albeit small ones - except my little finger nails.
Still not sure if I should get my levels checked! It has not been eating raw that has made these changes. It is the rest of my lifestyle that has caused the change I think.
