Dubious and unhelpful
on 4 May 2015
It's all a bit dubious and not particularly practical. For example, the way to know the correct dosage of a particular vitamin is to take a lot until it makes you ill, then reduce the dose a bit. For people with serious health problems, who are probably more likely to take mega-doses in desperation, a spell of nausea, vomiting or diarrhea can be disasterous and I think this is highly irresponsible of the authors. Sometimes the recommendation is to take vitamins intravenously, but given a doctor isn't likely to agree to this, how can anyone do it? There is maybe one fleeting mention about the quality of the products you take, but it's not highlighted. There are several statements which I'm pretty sure are incorrect, such as megadosing on vitamin D not being harmful and that B12 deficiency is rare. [Anyone who has been vegan for more than 2 years, most vegetarians, most of the elderly, anyone under stress, pregnant (the list goes on) is probably deficient.] Those erroneous references make me mistrust the rest, even though some of it is presented in quite a convincing way, so I won't be following the recommendations.
Instead of this book, I recommend The Calcium Lie which has more reliable information about vitamin dosage and how taking incorrect dosages of any vitamin, and especially synthetic ones, can have severe and lasting detrimental effects.
