Can vitamin C really help with chills and sneezes this winter?
Vitamin C is an effective water-soluble antioxidant, able to trap reactive oxygen species (ROS). It forms part of the antioxidant defense system of phagocytes. A comprehensive meta-analysis in 2013 concluded that a dose of 200 mg per day of vitamin C reduces the duration of colds. A recent study suggests that this effect is due to the improved migration of virus- killing neutrophils through chemotaxis.
Using nutrigenomics to uncover how the potent antioxidant properties of hydroxytyrosol can reduce the risk of cardiovascular disease
In his recent work, Francesco Visioli – Professor of Human Nutrition in the Department of Molecular Medicine at the University of Padova in Italy – has investigated the biological and pharmacological properties of olive oil phenolics, including hydroxytyrosol, and their ability to reduce the risk of atherosclerosis and cardiovascular disease.
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.
A double-blinded, randomized controlled trial carried out with 150 newborn infants in Italy has demonstrated the protective effect of an intervention of 0.28 mg lutein provided at 6 and 36 hours after birth against oxidative stress.
