A new study reports a low plasma vitamin E concentration in the first trimester of pregnancy may elevate the risk of early pregnancy loss.
The observational study measured the blood vitamin E concentrations of 1605 pregnant Bangladeshi women at an average of 10 weeks of gestational age and documented cases of miscarriage (1). The study results showed that women with low alpha-tocopherol (below 12.0 micromol/L) and gamma-tocopherol (below 0.81 micromol/L) levels had a significantly increased risk of miscarriage.
The researchers commented that vitamin E (tocopherols) seems to play a significant role in oxidative defense, including mechanisms that protect the maternoplacental fetal unit. Oxidative stress can arise through the enhanced production of reactive oxygen species or a deficiency of antioxidant defenses resulting from inadequate dietary antioxidant intake, decreased synthesis of antioxidant enzymes, or increased antioxidant use (2). Increased oxidative stress and resulting lipid peroxidation have been linked to pregnancy complications such as preeclampsia (3) and early pregnancy loss (4). For example, elevated plasma lipid peroxide and lower vitamin E status were reported in patients with a recurrent abortion (5).

Low serum vitamin D levels are common in sufferers of the painful condition rheumatoid arthritis. This condition is caused by inflammation. Vitamin D has beneficial immunomodulatory effects, so even low dose supplementation could enable the dose of conventional rheumatoid arthritis therapies to be reduced, with the consequent benefit of a reduction in side effects. A very recent trial supports this hypothesis.
