Vitamin D and calcium have long been associated with strengthening your bones, but their health benefits may extend to improving your life expectancy as well. A Danish research study discovered that taking these two essential nutrients in supplement form can enhance your overall health, thereby increasing your lifespan.
The research by Dr. Lars Rejnmark at Aarhus University Hospital in Denmark is the most extensive study of the effects of calcium and vitamin D on mortality to date. The intriguing results revealed a decrease in mortality by 9% over a three-year period among elderly patients who used vitamin D supplements in combination with calcium. However, such results were not apparent in those who were on vitamin D alone.
The study brought together a diverse group of participants, analyzing pooled data from eight randomized controlled trials, each with over 1,000 participants. The patient database consisted of approximately 90% women, with an average age of 70. Besides the nine percent reduction in deaths during the study of those treated with a combination of vitamin D and calcium, participants also experienced several other health benefits.
Initially, earlier studies had suggested that calcium supplements, with or without vitamin D, could have negative effects on cardiovascular health. Rejnmark’s research, while not altogether eliminating such drawbacks, maintains that calcium and vitamin D supplements with elderly participants are not harmful to survival. On the contrary, they may have favorable effects on a person’s overall health.
To better understand the reasons behind the findings, let’s delve into the two vital nutrients. First, vitamin D plays a critical role in many aspects of our health, from supporting bone health to mood regulation. It’s sometimes referred to as the “sunshine vitamin” because our bodies naturally produce it when exposed to sunlight. However, for many people – particularly the elderly who may not have regular exposure to sunlight or may experience age-related declines in vitamin D production – taking vitamin D supplements can help increase levels in the body.
Calcium is a vital mineral that strengthens bones and teeth, aids in blood clotting, muscle function, and nerve transmission. In most people, calcium levels remain stable because the body stores 99% of it in bones and teeth. However, deficiencies can occur if calcium intake is insufficient, or if the body doesn’t absorb it properly. This can lead to ailments such as osteoporosis, which often affects older adults. Taking calcium supplements contributes to balancing calcium levels in the body, improving overall bone health.
So, why do these two nutrients offer increased benefits when taken together? Combining vitamin D with calcium has the advantage of optimizing calcium absorption. It’s essential to understand that vitamin D helps the body absorb and retain calcium, working in harmony with the mineral to strengthen bones.
Incorporating calcium and vitamin D supplements into your diet is a sensible decision, but it’s crucial to ensure the recommended dosages are followed. The National Institutes of Health (NIH) suggests 1,000-1,200 milligrams of calcium per day for adults, and the daily recommended amount of vitamin D varies depending on age, typically ranging from 600-800 IU (international units) per day.
However, before starting any supplements, consult your healthcare provider, as not all supplements are suitable for everyone. It is essential to consider pre-existing conditions, prescription medications, and overall health when deciding whether to include these supplements in your daily routine.
To sum up, the combination of Vitamin D and calcium supplements provides numerous health benefits, particularly for older adults. These two essential nutrients, when taken together, may not only strengthen bones but also improve your life expectancy. As science continues to advance our understanding of the human body, it becomes increasingly clear that utilizing the latest research findings can lead to better health, longevity, and well-being.
