Calcium and Vitamin D Supplement, once again the relationship between vitamin D and calcium has come to the forefront. This is by far not new news because we have known the relationship between vitamin D and calcium absorption for many decades. The best calcium supplements should certainly provide enough vitamin D to help with the absorption of the calcium contained in the formula. Certainly not all calcium supplements are created equally.
Many of them contain nothing more than ground-up rocks and stones, which are extremely difficult for people, especially over the age of 50, to break down and absorb. If we are going to consider calcium supplements in the prevention of osteoporosis or bone loss, it is then essential that not only vitamin D be a factor but also the many trace elements we know also contribute to overall calcium absorption. Calcium with vitamin D is a good place to start but then we must also consider micro trace elements such as manganese, boron, copper, zinc, and even strontium.
Clinical studies have shown that the addition of strontium to a calcium and magnesium formula can enhance and increase the absorption and uptake of calcium back to the bones as much as 10 fold. It is sad that many supplement manufacturers neglect to include this essential but very deficient trace mineral. Recent studies have shown that bio-available calcium supplements including vitamin D and trace minerals, are now essential and beneficial for people of all ages.
In the past we used to focus on these supplements for people over the age of 50 due to potential bone loss but today science has shown that when younger people use these supplements regularly the benefits are numerous. Young athletes in their teens, 20s and even 30s can benefit by having stronger bones due to proper mineral absorption. Doing so has proven to reduce the amount of injuries, fractures and broken bones in younger people.
