by Chris Masterjohn
Vitamin A will not work properly without vitamin D. Also, Vitamin D is necessary to prevent Vitamin A toxicity.
Vitamin A deficiency and disruption is an important element of environmental illness. Both articles mention pre-existing vitamin A defects as a risk factor.
Environmental Chemicals and Environmental Illness: A Major Role for
by Frederick W. Plapp, Jr. PhD
Connects autoimmune illness and environmental illness with genetic difficulties in synthesizing vitamin A. Describes how pesticides, dioxins, and PCBs poison the enzymes that synthesize vitamin A and the carrier protein that transports it.
Autism a G-Alpha Protein Defect Reversible with Natural Vitamin A?
by Mary N. Megson, MD
The combination of gluten damage to intestinal microvillae, measles virus, pertussis toxin, and synthetic vitamin A (palmitate) affects the metabolic pathways modulated by G alpha protein. This affects vision, sensory perception, language processing, and attention. In case studies, autistic children dramatically improved with cod liver oil (natural vitamin A), a gluten-free diet, and/or an additional neurological drug. The biochemistry is also relevant to chronic fatigue syndrome, fibromyalgia, autoimmune disease, and gluten enteropathy (celiac disease), among others.
Can damage to vitamin A metabolism by environmental chemicals be reversed?
