This book is a life saver.
I have pernicious anaemia and soon after diagnosis searched on Amazon for a relevant book. Luckily this had just been published. Sally explains all the different 'faces' of lack of B12. Why it's so important to the body and how easily it gets mixed-up with other diagnosis.
Sally explains about her own diagnosis and from her experience as a nurse in a busy out-patients, the multitude of conditions that are 'caused' by lack of B12.
Soon after I was diagnosed a member of my family started to get dementia symptoms and if I hadn't got this book I would never have known what was wrong. It gave me the courage to insist on blood tests and get the treatment that was needed.
It has all the facts you need and more. What types of supplements to take and how, what tests are needed, how it can be mistaken for other illnesses, who might have a risk profile and what steps to take to getting healthy.
I am eternally grateful for her wonderful guide:)
