A recent study on Vitamin D’s effects has discovered that an excess of the vitamin can lead to potentially slow reaction times as well as elevate risks of falling when it comes to older people. An extremely essential vitamin, Vitamin D, helps in building and maintaining healthy teeth and bones. Without this particular vitamin, our bodies are unable to absorb the primary component of our bones, calcium.
Further, Vitamin D also has the potential to protect us against diabetes and cancer. It is synthesized by our bodies when our skin gets exposed to sunlight. The quantity of the vitamin produced by our skin is dependent on various factors. This includes our place of residence, season as well as skin pigmentation. For example, the production of Vitamin D may diminish or be totally absent during winter.
Foods like sardines, salmon, canned tuna, egg yolks, shrimp, mushrooms, oatmeal and oysters are rich sources of Vitamin D. For certain older adults, absorption of Vitamin D is more difficult as they may be unable to receive regular solar exposure. For such individuals, consumption of vitamin supplements or multivitamins can be helpful in boosting bone health as well as improving memory. Past studies have established links between deficiency of vitamin D and medical conditions such as diabetes, depression, dementia, schizophrenia and autism.
Although it is important to consume vitamin D, too much exposure can pose risks. Recently, a study on the part of Rutgers University discovered older, overweight women taking more than thrice the recommended quantity of the vitamin daily, suffered from noticeably slow reaction times. The study group analyzed the impact of this vitamin on 3 clusters of women who were aged in the range of 50 to 70 years, using a controlled randomized trial. The results found a marked improvement in learning and memory in groups taking excess of the recommended daily dosage. However, these same groups additionally noted a significant slowdown in the time of reaction.
