B12: Water-Soluble Vitamin Deficiency & Toxicity Symptoms

Results After control for demographic characteristics, cancer, smoking, alcohol intake, serum ferritin, and serum creatinine, low versus normal vitamin B status was associated with anemia [odds ratio OR: Conclusion In seniors with low vitamin B status, high serum folate was associated with anemia and cognitive impairment. When vitamin B status was normal, however, high serum folate was associated with protection against cognitive impairment.

The main goal of this program is the prevention of neural tube birth defects 1. The elderly are of particular concern because of age-related declines in vitamin absorption and extraction of vitamin B from protein 4 — 11 and age-related increases in autoimmunity against intrinsic factor or the gastric parietal cells that produce it 11 — Fears of harm from fortification to seniors and other Americans with low vitamin B status are based on early case reports of pernicious anemia that detail the alleviation of anemia but the precipitation or exacerbation of neurologic or neuropsychiatric sequelae after folic acid administration—an early form of treatment based on the mistaken idea that a lack of folate was the problem 8 Modern reports on the effects of high folic acid intakes are infrequent because of the rarity of identified cases of vitamin B deficiency affected by oversupplementation or mistreatment with folic acid.

However, close study of the original case reports showed no proof that folic acid therapy exacerbated central nervous system CNS —related symptoms 1516and modern case reports and studies suggest that folic acid therapy did not cure anemia either 17 — Such data support the idea that folic acid can be safely added to foods in moderation, but recent editorials have stressed the need for systematic study of the hypothesis that high folate intakes cause harm 21 Data collected in the most recent National Health and Nutrition Examination Survey NHANES afforded us the opportunity to study interrelations between serum folate and vitamin B status in relation to anemia, macrocytosis, and cognitive impairment in the age of folic acid fortification.

The survey is currently implemented as a continuous annual survey and uses a complex multistage probability design to select a representative sample of the noninstitutionalized US civilian population. To increase the precision of estimates derived from the survey, adolescents, the elderly, Mexican Americans, and blacks are oversampled. Consistent with NHANES analytic guidelines, we combined data from the 2 most recent surveys into a single data set — Trained interviewers used a computer-assisted personal interview system to interview participants in their homes.

The participants were also asked to report to a mobile examination center MEC to provide further interview data and undergo a physical examination that included phlebotomy. Of senior survey participants, were eligible, were ineligible, and eligibility status could not be determined for Complete information for analyses pertaining to anemia was available for seniors, and complete information for analyses pertaining to cognitive function was available for seniors.

Based on the findings of the present study, it can be concluded that the low levels of these biochemical markers, that is, vitamin B12 and folate may be relevant to the clinical course of AD and VaD and should be considered for therapeutic intervention. However, it remains an open question whether or not these interventions in terms of B vitamin supplementation a combination of folate, vitamin B12, and vitamin B6 will improve cognitive functions or retard the rate of cognitive decline in older adults with or without dementia.

Hence at present, B vitamin supplementation should be reserved for the treatment of documented deficiency states, but not expressly for the prevention or treatment of cognitive disorders, including AD.
