The Importance of Elastin in Skin and Vascular Health
Elastin is crucial for keeping our skin firm and flexible, and it plays a similar role in the walls of our blood vessels, which are part of the circulatory system. Without enough healthy elastin, arteries can become stiff and less capable of handling the internal pressure they are designed to manage. Over time, this can damage both the vascular system and the organs it supplies.
The Study Explained
To explore the link between vitamin D and arterial stiffness, researchers at Georgia Health Sciences University conducted a study involving 44 black teenagers, a group generally at higher risk for arterial stiffness compared to other ethnic groups.
The teens were split into two groups. One group received the U.S. Department of Agriculture’s Food and Nutrition Board’s recommended daily dose of 400 international units (IU) of vitamin D. The other group received an experimental dose of 2,000 IU per day, which is five times the recommended amount.
Over a 16-week period, both groups were closely monitored. Researchers measured arterial stiffness using a non-invasive method called “pulse wave velocity,” which tracks the time it takes for sound waves to travel a certain distance within the arteries.
The Findings
The results showed that teens in the 2,000 IU group had normal arterial elasticity and were fully sufficient in vitamin D. In contrast, the 400 IU group showed less promising results. Despite adequate sun exposure and receiving the recommended daily vitamin D, most teens in this group exhibited signs of premature arterial stiffness, indicating a higher risk for future health issues.
These findings suggest that maintaining sufficient vitamin D levels has significant health benefits, including better arterial health. This underscores the potential importance of vitamin D supplementation, even for those who get plenty of sunlight and consume foods rich in vitamin D.
Taking a Vitamin D Supplement
Vitamin D supplements are affordable and easy to find at grocery stores or pharmacies. However, choosing a high-quality supplement is essential. Look for products with natural ingredients to ensure you get the best benefits.
