Core Minerals By USANA CellSentials Overview & Drug Interactions

Calcium is a vital nutrient found in various foods such as dairy products, certain vegetables, and many fortified items. Over 99% of the body's calcium is stored in the bones and teeth, predominantly as hydroxyapatite. The remaining calcium circulates in the blood, extracellular fluid, muscles, and other tissues, where it is essential for processes like nerve signaling, muscle contraction, vascular activities, glandular secretion, and maintaining cell membrane and capillary permeability. It also plays critical roles in enzyme reactions, respiration, kidney function, and blood clotting, and is involved in neurotransmitter and hormone release, amino acid uptake, vitamin B12 absorption, and gastrin secretion. Calcium balance changes with age: it is positive during periods of growth, stable in adulthood, and tends to become negative in older age. Calcium loss occurs through feces, urine, sweat, and shedding skin cells. In women, reduced estrogen levels decrease calcium absorption and retention, increase bone turnover, and lead to lower bone mass. Calcium supplements come in various forms, including citrate and carbonate, which differ mainly in their calcium content and absorption rates. Calcium citrate is easily absorbed and can be taken without food, making it suitable for older adults or those with low stomach acid. In contrast, calcium carbonate, which contains a higher percentage of calcium, is best absorbed when taken with meals.

Iodine is a mineral that is crucial for our body's ability to produce thyroid hormone, which helps control our growth, metabolism, and energy levels. A lack of iodine in the diet is a common problem around the world and can lead to intellectual development issues. Adding iodine to salt (i.e., iodized salt) has helped reduce this problem. Iodine is commonly utilized as a dietary supplement, both in multivitamin preparations and as a standalone ingredient as it is purported to have overall health and wellness benefits, not just in those who are deficient. One such standalone iodine product is 'Iodoral'. Studies have shown iodine supplementation may help improve cognitive function and boost energy levels but more research is needed. It is recommended that you should be under medical supervision if you plan on taking iodine as there may be a risk of certain side effects with high dosages.

Magnesium is a mineral that is essential for the proper functioning of the body. It plays a role in many important physiological processes, including the contraction and relaxation of muscles, the transmission of nerve impulses, and the regulation of blood pressure. Magnesium is found in a variety of foods, including leafy green vegetables, nuts, and grains, and it is also available as a dietary supplement. There are several different forms of magnesium that are available as supplements, all of which can be used to prevent deficiency. Additionally, magnesium is purported to have several different health benefits, such as improving sleep, reducing muscle cramps, reducing anxiety, and preventing or treating migraines. Although magnesium is essential for health, magnesium-containing foods and supplements can interact with some prescription medications if used at the same time.

Zinc is a mineral that is essential for the proper functioning of the human body. It is involved in many important physiological processes, including immune system function, wound healing, taste, and smell. Zinc is found in a variety of foods, including meat, seafood, and whole grains, and it is also available as a dietary supplement. Zinc supplements may be used to treat or prevent zinc deficiency, which can occur due to certain medical conditions, such as gastrointestinal disorders, alcohol abuse, and certain medications. Zinc supplements may also be used for other purposes, such as to boost the immune system, improve acne, and reduce the severity and duration of colds. There are several different forms of zinc supplements available, including zinc gluconate, zinc acetate, and zinc sulfate. The most common form of zinc supplements is zinc gluconate, which is well absorbed and is less likely to cause stomach-related side effects than other forms of zinc.

Selenium is an essential trace element that plays a crucial role in various physiological functions in the human body. It is often included in dietary supplements due to its antioxidant properties and its contribution to maintaining a healthy immune system. Selenium is important for thyroid function and may also have a role in protecting against certain chronic diseases. However, it's essential to note that excessive selenium intake can be harmful, so it's crucial to adhere to recommended daily allowances and consult with a healthcare professional before taking selenium supplements.

Manganese is an essential trace mineral that plays a vital role in various physiological processes within the human body. It is required for proper brain function, bone formation, enzyme activation, and wound healing. Manganese also contributes to metabolism, antioxidant defense, and the formation of connective tissues.

Chromium is a trace mineral that is found in small amounts in the human body. It is believed to play a role in the metabolism of carbohydrates, fats, and proteins. It is used as a dietary supplement for its purported ability to help with weight loss and blood sugar control. There is some evidence to suggest that chromium supplements may help to improve blood sugar control in people with type 2 diabetes, although the results of studies on this topic have been mixed. Some studies have found that chromium supplements can improve insulin sensitivity and reduce blood sugar levels in those with poorly controlled diabetes, while others have found no significant effects.

Boron is a trace mineral that is found in a variety of foods, including fruits, vegetables, nuts, and legumes. It is also available as a dietary supplement. Boron is thought to play a role in bone health, as it may help the body metabolize calcium, magnesium, and phosphorus. Some preliminary research also suggests that boron may have anti-inflammatory effects and may help to improve cognitive function. However, more research is needed to confirm these potential benefits. It is important to note that boron is not an essential nutrient and deficiency is rare. The recommended dietary allowance (RDA) for boron is not established, however, the safe upper limit is 20mg/day. Taking high doses of boron can cause skin irritation, nausea, vomiting, and diarrhea. There are several patented forms of boron available in dietary supplements, such as Albion Bororganic Glycine.

Silicon, atomic number 14, is the second most abundant element on Earth, after oxygen. It is present in the human body in small amounts (such as in the skin, hair, and nails) and is considered a trace mineral in that regard. Dietary sources of silicon include oats, barley, rice, and some fruits/vegetables. Silicon is a popular dietary supplement, often consumed in the form of silica, which is a chemical compound made up of silicon and oxygen, or as silicic acid (also known as orthosilicic acid). Another common form of silicon utilized is Choline-stabilized orthosilicic acid (ch-OSA), which is the active ingredient in the popular product Biosil. Silicon is used for its purported effects to improve the health and appearance of the skin, hair, and nails. It has also historically been used for other health conditions, such as osteoporosis, cardiovascular disease, and cognitive decline.

Vanadium is a chemical element with the symbol V and atomic number 23. It is a soft, silvery-grey metal that is found in small amounts in various minerals and rocks. Vanadium is used in a variety of industrial applications, including the production of steel and as a chemical catalyst. Vanadium is an essential trace mineral that is required by the body in small amounts for proper growth and development. The human body does not naturally produce it. It is involved in several important biological processes, including the metabolism of carbohydrates and the synthesis of proteins and DNA. Vanadium supplements are sometimes marketed as a way to improve athletic performance, lower cholesterol levels, and manage diabetes. However, there is limited scientific evidence to support the use of vanadium supplements for these purposes and high levels of vanadium can be toxic. It must be used cautiously.

N-acetyl cysteine (NAC) is derived from the amino acid cysteine. It is used as a prescription medication to treat acetaminophen overdose and to help thin mucus in people with certain respiratory conditions. It is also used as a dietary supplement. NAC has a number of potential health benefits. It is a source of the antioxidant enzyme glutathione, which is important for protecting cells from oxidative stress and supporting immune function. It also may have anti-inflammatory effects and studies show it may support healthy brain function. It is generally considered safe to take NAC supplements in recommended doses.
