Optimal nutrition means different things to different people. We all know the basics: eat your vegetables, cut down on fats and sweets, drink plenty of water - things we've heard since we were kids. Some of us heed this advice and eat plenty of fruits, vegetables, fiber and other wholesome foods, but others may eat broccoli once or twice a week and think that their nutritional bases are covered. Chances are, we could all benefit by doing more to ensure that our nutritional needs are being met. Why is this so important? Because optimal nutrition is essential for the healthy functioning of our body. Without it, subtle functional changes may occur that impede our progress on the road to vibrant health. You may not be aware of any problems, but that doesn't necessarily mean that your body is functioning optimally. An understanding of the many roles that nutrients play in our body is the first step in achieving that goal.
The nutrients required to sustain life are the macronutrients - proteins, carbohydrates, and fats - which supply energy and build tissue; the micronutrients - vitamins and minerals - which are used by the body in much smaller amounts but are important in the regulation of all body processes and also act as structural components; and water, the overall vital nutrient sustaining all our life processes.
If we supply our bodies with adequate amounts of these nutrients, and in the proper ratios, then we help ensure optimal nutrition and a solid foundation for health. But what about you?
Chances are that you may not be receiving all the nutrients you need from the foods you eat. According to recent health surveys, most of us don't even meet the Recommended Dietary Allowances (RDAs) of some essential nutrients, and few of us consume the recommended five daily servings of nutrient rich fruits and vegetables.
So how do you know if you are providing your body with the nutrients it needs? There are many signs that are indicative of optimal health: high energy; ideal weight; good muscle development; smooth and clear skin; glossy hair; clear eyes; normal appetite, digestion and elimination; and alert mental functions. If you are lacking in any of these areas, your foundation for health may be missing some important pieces.
Why is it vital that we supply our bodies with optimal regular intake of all micronutrients? Because vitamins and minerals are essential for a myriad of processes in our body; energy metabolism; growth and maintenance of skin, bones and other tissues; immune system function; brain functions; hormone production and regulation; detoxification; and many others. Because each micronutrient plays indispensable and diverse roles, a single deficiency can adversely impact these body functions.
Some of the micronutrients have achieved greater fame than others; for instance, everyone knows that calcium is essential for strong bones, vitamin E is good for our skin, and vitamin A is important for eyesight. But do you know why we need zinc, or niacin, or vitamin B6? By looking at the following chart, you can see some of the important and varied roles that each micronutrient plays in our body.
Eating a well-balanced diet of wholesome, nutritious foods and taking a scientifically balanced multiple vitamin/mineral supplement helps to ensure that your body receives the optimum levels of each vital nutrient it needs. This is an essential foundation for good health.
Bone is a living tissue that forms the framework around which the body is built. This framework, or skeleton, contains over 200 separate bones that support and give shape to the body and protect its vital organs. Contrary to a common misconception, bone is a living substance! In fact, bone is one of the most active tissues in the body. It is constantly being broken down and being rebuilt in a process called remodeling and, like any other living tissue, needs nourishment to stay strong and healthy.
To begin the process of bone formation, bone cells use proteins and other building blocks to produce a substance known as collagen. Collagen fibers develop quickly to form an organic mesh, or net, that calcium, phosphorus, and numerous other minerals attach to. Over a period of days and weeks (and through a crystallization process involving substitution and addition of various minerals) the mixture of different minerals attaching to this organic net changes, producing the finished product called hydroxyapatite crystals. These hydroxyapatite crystals are what makes bone so hard. It is easy to appreciate that bone (pictured in the illustration) is much more than just calcium.
Other cells facilitate the nourishment of bone by participating in the exchange of nutrients between the bone and the blood. Still other bone cells help to shape, or remodel, the bone by digesting any extra unneeded pieces.
There are three ways that strong bones are dependent on proper nourishment: 1) To keep the bone cells healthy and active. 2) To supply the variety of important nutritional building blocks needed to form the organic matrix of bone. 3) To supply the complex of minerals that need to be placed on the organic net making up the finished, hardened component of bone known as hydroxyapatite crystals. With proper nourishment, a healthy lifestyle, and favorable genetics, healthy bones can last a lifetime!
Microcrystalline hydroxyapatite concentrate (MCHC) is derived from whole bone and is available as a nutritional supplement. It provides much greater nourishment than just calcium. MCHC contains protein and other ingredients that comprise the organic portion of bone, as well as calcium and other minerals in the normal physiological proportions found in raw bone.
There is no doubt that calcium is essential for healthy bone formation; however, trace minerals and organic factors are also important. Because bone is a complex, highly mineralized tissue, a number of trace mineral deficiencies can impair bone formation and remodeling. Trace minerals also act as cofactors for several enzymes involved in the production of the organic portion of bone. Because MCHC is actual bone, it contains these vital components that are important for a healthy skeleton. It truly is comprehensive bone nourishment.
As we age, our ability to absorb calcium and other minerals may decline. The calcium in MCHC is bioavailable and may be well absorbed.
A number of benefits related to MCHC are summarized below:
All MCHC products are not created equal. There are many synonyms for the word "hydroxyapatite" that are commonly, yet erroneously, equated with "microcrystalline hydroxyapatite concentrate." They lack the full complement of minerals, organic factors, and the microcrystalline structure so important to the effectiveness of true MCHC. Modern laboratory analysis can now be conducted to confirm the presence of authentic MCHC in a nutritional supplement.
