useful if not essential

I own this book for at least twenty years and I think not an exaggeration to say that this is the one I have the most open and used. The tables are especially useful when looking, for example, what food has the most such as vitamins or minerals.
I will not repeat the plan of the book is very well detailed on the back cover. Just a little mistake to be rectified: the fourth part, it will be understood, not speaking again dietary supplements but common conditions for which are offered dietary supplements, juices, capsules and essential oils. There are no errors in these councils. The authors are familiar with the field of alternative medicine.
So in the end we can modulate its power and strengthen its position in food supplements based on a weakness or pathology.
I highly recommend this practical book by its presentation by tables and lists, and accurate.
