Vitamin D is a fat-soluble vitamin found in certain foods and is manufactured in the skin as a result of direct exposure to sunlight. The liver and kidneys convert vitamin D from food sources or sunlight to its active form, calcitriol.

Vitamin D helps the body maintain healthy levels of calcium and phosphorus and is therefore essential for building and maintaining healthy bones. Calcium, which is the principal element in bone, can be absorbed by the body only when vitamin D is present.

Rickets, a vitamin D deficiency disease responsible for softening and weakening bones in children, used to be quite common but now is rarely seen in countries that have adopted the practice of fortifying milk products. Vitamin D and calcium are involved in many body functions, including keeping the immune and nervous systems healthy.

Low concentrations of Vitamin D may lead to malabsorption of calcium and bone loss to an even greater degree in older house-bound people. [31] Our sedentary lifestyle, coupled with our poor dietary intake, is undoubtedly a major contributor to bone disease.

We use Vitamin D3 cholecalciferol which is the better form of vitamin D

We use the same RATIO of calcium to magnesion as the Dr Guy Abraham study of 1 part calcium to 1.2 parts of Magnesium. - 250 mg calcium - 300 mg magnesium.

Discrepancies in labeling can be deceptive and make people believe they are getting more calcium than they think they are. Unless the ingredients are in brackets ( ) you are only getting a fraction of the ingredient, e.g. Calcium Citrate 1000 mg is the same as Calcium (Citrate) 210 mg.

Calcium citrate is the best calcium supplement for absorption but unfortunately it has a low calcium content. Active Liquid Calcium combines calcium citrate with the high calcium content of tri-calcium phosphate for the best of both worlds.

NOTE: All our ingredients are 'ELEMENTAL'. e.g. Our 250 mg is ALL calcium.

The mineral magnesium is important for every organ in the body, particularly the heart, muscles, and kidneys. It also contributes to the composition of teeth and bones.

Most importantly, it activates enzymes, contributes to energy production, and helps regulate calcium levels as well as copper, zinc, potassium, vitamin D, and other important nutrients in the body.

Without enough magnesium, calcium can collect in the soft tissues and cause one type of arthritis. Not only does calcium collect in the soft tissues of arthritics, it is poorly, if at all, absorbed into their blood and bones. But taking more calcium is not the answer; it only amplifies the problem.

In fact, excessive calcium intake and insufficient magnesium can contribute to both of these diseases. Magnesium taken in proper dosages can solve the problem of calcium deficiency.

Magnesium is available in many foods. However, most people in the United States probably do not get as much magnesium as they should from their diet.

We use Magnesium Citrate which is the natural form of Magnesium.

Zinc is an essential trace mineral, which means that it must be obtained from the diet since the body cannot make enough. Too much calcium reduces zinc absorption in bone. [27]

Zinc is an essential trace mineral, which means that it must be obtained from the diet since the body cannot make enough. Next to iron, zinc is the most abundant trace mineral in the body.

Stored primarily in muscle, zinc is also found in high concentrations in red and white blood cells, the retina of the eye, bones, skin, kidneys, liver, and pancreas. In men, the prostate gland stores high amounts of zinc.

Zinc plays an important role in the immune system, which may explain why it is helpful in protecting against infections such as colds. Zinc also plays a role in the regulation of appetite, stress level, taste, and smell.

It is important to know that too much calcium reduces zinc absorption in bone.

We use Zinc Citrate which is the natural form of Zinc.

Selenium is an essential mineral found in trace amounts in the human body. It works as an antioxidant, especially when combined with vitamin E, by scavenging damaging particles in the body known as free radicals.

These particles occur naturally in the body but can damage cell membranes, interact with genetic material, and possibly contribute to the aging process as well as the development of a number of conditions including heart disease and cancer.

We use Sodium Selenomethionine which is the more natural form of Selenium.

Copper is a mineral found in trace amounts in all tissues in the body. Although only a small amount is needed, copper is an essential nutrient that plays a role in the production of hemoglobin (the main component of red blood cells), myelin (the substance that surrounds nerve fibers), collagen (a key component of bones and connective tissue), and melanin (a dark pigment that colors the hair and skin).

Copper also works with vitamin C to help make a component of connective tissue known as elastin.

Copper is known to activate the enzyme that produces elastic fibers in tissues.

It is important to know that too much calcium depletes copper.

We use a Lysine Complex which is the more natural form of Copper.

Manganese is a mineral found in large quantities in both plant and animal matter. Only trace amounts of this element can be found in human tissue, however.

Manganese is predominantly stored in the bones, liver, kidney, and pancreas. It aids in the formation of connective tissue, bones, blood-clotting factors, and sex hormones and plays a role in fat and carbohydrate metabolism, calcium absorption, and blood sugar regulation.

Manganese is also necessary for normal brain and nerve function.

Bran and foods high in phosphorous and low in calcium deplete manganese.

We use Manganese Citrate which is the natural form of Manganese.

Chromium deficiency severely impairs glucose tolerance. We have added Chromium - GTF, because without insulin, we are at risk for osteoporosis. (GTF stands for Glucose Tolerance Factor, which is the ability to regulate blood sugar level.)

We use natural polynicotinate which is food based and organic. Other forms of chromium are inorganic such as chromium picolinate, chromium chloride and chromium chelate.

Calcium and phosphorus are "co-dependent" nutrients affecting the health of bones and soft tissues.

Bone disease can develop when calcium and phosphorus are not balanced and within good levels. When phosphorus is too high, (drinking too many soda's?) the body takes calcium out of the bones to bind with the phosphorus and remove it from the blood. Bones become brittle as a result.

Dr. Heaney(A) recommends that patients use a source with both calcium and phosphorus, "such as dairy products and/or a calcium phosphate supplement."

Boron is a trace element which has an important influence on both calcium and magnesium metabolism and helps in the manufacturer of vitamin D.

Boron is concentrated in the bone, spleen, and thyroid indicating boron’s functions in bone metabolism and suggesting a potential role for boron in hormone metabolism.

Boron also reduces calcium, magnesium and estrogen losses thus playing a major role in preventing bone loss.

Boron is thought to be useful to increase muscle mass; increase muscle strength; maintain bone density; improve calcium absorption; decrease body fat.

Silica, also known as Silicon, is derived from the horsetail herb and is the most abundant element on the planet. Our body needs it for the formation of collagen for bones and connective tissue; for healthy nails, skin, and hair; and for calcium absorption in the early stages of bone formation.

Bone growth involves the process of adding calcium for hardness, plus increasing collagen. Silicon is essential for both of these processes.

Among the known catalysts that facilitate the functions of silicon indirectly are magnesium, manganese, potassium and boron.

We use organic silicon found in horsetail. It is believed to promote bone and cartilage formation and is useful for treating brittle nails and related conditions.
