I am a board-certified adult and child psychiatrist specializing in Nutritional Psychiatry. I have been in private practice for forty years and taught psychiatry at UCSD School of Medicine as a voluntary faculty member, receiving two teaching awards.
This nutrition/health and wellness book was written to inform people about the disparity between what we expect of our vitamin supplements and what they actually provide. Over the past fifty years, increasingly processed food has had its natural bioactive vitamins stripped out while having the synthetic forms substituted back in through fortification and supplementation. These artificial vitamins are poorly made, poorly absorbed, and poorly utilized, eventually being flushed away unused.
It is this nutritional deficiency that is exacerbating the universal illness of chronic inflammation which contributes to the onset of depression, dementia, diabetes, cancer, cardiovascular disease, etc. B12 and folate vitamers are the forms of vitamins that are actually used by the cells. These vitamers are critical to the performance of every biochemical activity in the body from the expression of genes to the production of energy molecules to the cleansing of cellular waste products.
The book explains the newly understood cellular mechanism by which this occurs by focusing on the two most essential of the essential vitamins—B12 and folate. When there is a deficiency of either, other vitamins do not work well. For example, if you have plenty of vitamin D and calcium but not enough B vitamers, you can still develop osteoporosis.
