The goodness of milk

Milk is one of the most widely consumed and varied products in the world. It is a major ingredient in thousands of foods and beverages for added nutritional value. Milk is packed with essential nutrients and has more nutrients than any other single food, filled with a unique blend of carbohydrates, proteins, fats, vitamins and minerals. Milk contains more than 10 essential nutrients that can promote health and prevent disease.

It's widely recognised that milk and dairy products are the best source of calcium and other key bone-building nutrients. Obtaining calcium from milk is very advantageous as the balanced natural mineral profile therein enhances calcium absorption and mineral retention. Supplement fortification with calcium alone cannot provide the same benefits. No calcium supplement, taken in the absence of other essential vitamins and minerals and without proper diet and exercise, has ever been proven in clinical studies to help strengthen your bones. The best that can be said is that calcium supplementation helps slow down or stop bone loss. There are several factors that go into actually building bone mineral density or growing bone and the source of your calcium is a key factor. A breakdown of the major nutrient compositions is listed below for a better understanding of the benefits of milk.

Our healthcare professionals insist on using calcium from milk which is regarded as the "reference" calcium. Twenty-one minerals, including calcium, are essential for normal human growth and metabolism. All twenty-one minerals are found in milk, making milk the premier natural source of essential minerals.

Bioavialability

The beneficial effect of milk calcium, which makes it superior to other calcium sources, becomes apparent when comparing the effects on bone mass accretion. Studies have shown that the gain in bone mass density obtained by supplementation with milk calcium is still present years after the supplementation has ended. The bioavailability of calcium from a food source is best evaluated by measuring its effect on changes in bone mass over time. Bone is a dynamic system consisting of living cells embedded in a mineralized matrix including calcium, phosphorus, magnesium, potassium, zinc and copper. It is subject to breakdown, repair and rebuilding, just like any other tissue in the body. Minerals, such as those found in our products, are critical for the production of this matrix.

In sum, the studies of bioavailability of calcium from milk and dairy products compared to that of inorganic calcium have shown that the absorption of milk calcium is as good as that of other calcium sources. It is in relation to the effects on increasing bone mass that milk calcium proves itself to be superior to inorganic calcium sources. This becomes evident in studies showing that an acquired gain in bone mass obtained by supplementing with milk calcium is still present years after the supplementation has ceased. In opposition to this, bone mass increments obtained by supplementing with inorganic calcium have been shown to reverse to baseline when supplementation with calcium was withdrawn.
