hello,
our friend tom is right. William walsh is a very clever specialist in the nutrient field. this book "nutrient power" is a pearl, really amazing. to procede with the
starting dose read " Depression free naturally" of joan larsson and "antianxiety food solution" by trudy scott. dr scott give better orientations on zinc and b6 than joan larsson, but joan larsson explain better the other nutrients. buy the 2 books.
