Low Vitamin D Levels May Be Associated With Higher Risk Of Age-Related Macular Degeneration
Age-related macular degeneration is the number one cause of legal blindness in people over 50 in the United States. A recent study suggests that low vitamin D levels may be associated with a higher risk of age-related macular degeneration.
Participants in the study included 913 women. 550 of them had vitamin D levels of at least 20 ng/mL, which is considered to be an adequate level. 275 of the women had levels between 12 and 20 mg/mL and 88 had a deficient vitamin D level, which is defined as lower than 12 ng/mL.
The researchers found that the women who were vitamin D deficient were most likely to have age-related macular degeneration. However, increasing vitamin D levels higher than 12 ng/mL did not seem to lower the risk of age-related macular degeneration by any meaningful measure.
The researchers stated that their findings show that having deficient levels of vitamin D may be unhealthy for the eyes.
Researchers from The University of Buffalo conducted the study. It was published online ahead of print on August 27, 2015, in JAMA Ophthalmology.
Previous studies have associated vitamin D with reducing the risk of skin damage, reducing the risk of osteoporosis, combating diabetes, and improving age related macular degeneration.
Vitamin D can be found in milk, fortified cereals, fish, and eggs. Your body also processes vitamin D from the sun but it becomes harder for our bodies to process it as we age. A high quality vitamin D supplement is always a good option if you feel that you’re not getting enough through diet and sun.
