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.

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.
