Recent research, published in the journal Neurobiology of Ageing, suggests that Vitamin D supplements may help combat the effects of age-related eye disease, such as macular degeneration (AMD). Lead researcher Professor Glen Jeffery, from the Institute of Opthalmology at University College London, explains that the blood vessels supplying the retina can become inflamed and accumulate debris as we age. This can result in a decline of up to 30 per cent in the numbers of light receptive cells in the eye by the time we are 70.
As clinical trials with mice showed, vitamin D supplements can instigate a reduction in deposits of a toxic molecule called amyloid beta, which is known to contribute to the risk of developing AMD in humans. These findings give researchers hope that vitamin D supplements can provide a simple and effective way to prevent significant health implications in older people.
