Wednesday, July 29, 2009 at 21:37 According to a sizeable study published in the May issue of the Journal of Neurology, Neurosurgery, and Psychiatry, getting plenty of Vitamin D - the sunshine vitamin - may help keep you sharper as you age.
The study measured the vitamin D blood levels in more than 3,000 men aged 40 to 79, and then assessed their performance on standard cognitive tests. They discovered that men with lower levels of the vitamin scored lower on measures of cognitive agility when compared to those with higher levels - even after adjusting for differences like depression, physical activity levels and education. These factors all affect cognitive ability and agility as we age.
Saturday, May 16, 2009 at 16:47 As a cancer survivor I know the importance of Vitamin D supplements to help keep my breast cancer from returning, but my endocrinologist also tells me that it’s critical in keeping my bones strong, since the cancer meds have a way of making them brittle. So I take 3,000 IU daily of Vitamin D3 capsules. That’s right, 3,000. The Recommended Daily Allowance (RDA) - which seems to come from nutrition studies conducted in the 15th century or maybe the 1950’s - is still hanging in there with 400 IU for those under 70 years of age, and 600 IU for those over 70.
