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.

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.

Quercetin is a type of flavonoid, which is a class of compounds found in a wide variety of plants and foods. It is purported to have a number of health benefits such as anti-inflammatory, antioxidant, and immune-boosting effects. Studies suggest it may also help to reduce the risk of certain chronic diseases, such as heart disease. In addition, quercetin may have anti-allergic properties and may be helpful in the treatment of allergies and asthma. It is a popular dietary supplement worldwide and is often included in products that contain antioxidants or various vitamins/minerals. Its wide range of potential health benefits mean that it could potentiate the effects of other drugs (e.g., anti-hypertensives), which is why there are an abundant number of potential interactions listed for quercetin.

Stinging nettle (Urtica dioica) is a perennial flowering plant that belongs to the Urticaceae family. It is native to Europe, Asia, and North America, and is characterized by its green leaves and small, greenish-white flowers. Stinging nettle has small, stinging hairs on its leaves and stems, which can cause a painful rash when touched. The leaves and the roots of stinging nettle have been used in traditional medicine to treat a variety of conditions such as joint pain, diabetes, enlarged prostate, anemia, and urinary tract infections. It is also used as a diuretic and to help with allergies as it contains the compound quercetin. The leaves and stems of the plant are edible and can be consumed as a vegetable, usually after boiling or steaming to remove the stinging hairs, as the plant is rich in vitamins, minerals, and antioxidants.

Bromelain is a group of proteolytic enzymes derived from pineapples. It has been traditionally used for its anti-inflammatory and protein-digesting properties. Some research suggests it may have potential benefits for conditions such as allergic rhinitis, burns, cancer, diabetic foot ulcers, and postoperative pain, among others. However, the evidence for its effectiveness in these areas is lacking, and more research is needed. It is important to note that bromelain should not be confused with other protein-digesting enzymes. Pregnant and lactating individuals should avoid using bromelain due to insufficient information about its safety in these populations.

Licorice, also known as glycyrrhiza, is a plant native to parts of Europe, Asia, and the Mediterranean region. The root of the plant has been used for centuries in traditional medicine and is often consumed in the form of candy, tea, and supplements. Licorice has a number of purported health benefits, including the ability to soothe sore throats, reduce inflammation, and improve digestive problems. It may also have antiviral and antibacterial properties. Licorice naturally contains glycyrrhizin, or glycyrrhizic acid, which can have toxic effects if consumed in large amounts. However, licorice can be processed to remove glycyrrhizin, resulting in DGL (deglycyrrhizinated licorice). Many dietary supplements that contain deglycyrrhizinated licorice are often simply named 'DGL'.
