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.

Vitamin E is a fat-soluble vitamin found naturally in a variety of foods, including vegetable oils, nuts, seeds, and leafy green vegetables. Vitamin E is also available as a dietary supplement and is often added to skincare products. Vitamin E has many roles in the body, including protecting cells from oxidative stress and supporting immune function.

Niacin, also known as vitamin B3, is a water-soluble vitamin found in a variety of foods, including meat, poultry, fish, and fortified grains. It plays a variety of roles in the body, including in the metabolism of carbohydrates, fats, and proteins. It is also necessary for the production of energy in the body and in the synthesis of different hormones. Niacin deficiency is rare in developed countries, however, supplementation has been shown to have several positive benefits. For example, it can reduce the risk of diabetic neuropathy (i.e., nerve pain) and has been shown effective for treating some types of high cholesterol (extended-release niacin is used as a prescription drug in the United States for this purpose). There is a multitude of niacin forms available as dietary supplements, including NADH, niacinamide, and nicotinamide riboside, all with different properties.

Vitamin B12, also known as cobalamin, is a water-soluble vitamin crucial for several bodily functions. It plays a pivotal role in the formation of red blood cells, aiding in the prevention of anemia. Vitamin B12 is essential for maintaining a healthy nervous system and proper brain function, as it is involved in the synthesis of myelin, the protective sheath around nerve fibers. This vitamin is primarily found in animal-based foods such as meat, fish, dairy products, and eggs, making it important for vegetarians and vegans to consider supplementation. A deficiency in vitamin B12 can lead to neurological issues, fatigue, and cognitive impairment.

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.

L-glutamine is the most abundant free amino acid in the body, produced primarily in skeletal muscle and then released into circulation. It serves vital roles in various tissues, including the immune system, gastrointestinal tract, kidneys, and liver, where it supports essential functions such as maintaining intestinal integrity, immune response, and amino acid balance. Although traditionally classified as a non-essential amino acid, during periods of severe stress, glutamine becomes conditionally essential due to the body's increased demand. It acts as a critical nitrogen and carbon transporter between organs, and while the intestinal mucosa can synthesize glutamine, this production is insufficient during times of significant physiological stress. Dietary supplements generally contain L-glutamine as it is the biologically active form of the amino acid.

Creatine is an organic amine that occurs naturally in the body and is also found in certain foods, such as meat and fish. It is stored mostly in the skeletal muscles, where it is used to generate energy during physical activity. Creatine is a popular over-the-counter dietary supplement, and some evidence suggests it is effective at improving exercise performance, particularly during high-intensity activities such as weightlifting and sprinting. However, the degree to which creatine supplements may improve exercise performance can vary depending on the individual and the type of physical activity being performed Creatine is generally well-tolerated but may cause some minor side effects, such as cramping and water retention in some individuals. Long-term use has been rarely linked to kidney problems, but its use is generally regarded as safe. There are several different forms of creatine available, with the most common form being monohydrate salt. Other salt forms, including di-creatine citrate and 'pH buffered' creatine, are also available.
