Circulation Factors By Country Life Overview & Drug Interactions

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.

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.

Butcher's broom (Ruscus aculeatus) is a plant species in the lily family that is native to Europe and parts of Asia. It is a low-growing evergreen shrub with small, spiky leaves, clusters of small, greenish flowers and small red berries. Butcher's broom, specifically the rhizomes (underground stems) and roots, has been used in traditional medicine to treat a variety of conditions, including circulation problems, kidney issues, and varicose veins. It is thought to have anti-inflammatory, laxative and vasoconstrictive properties and is a popular dietary supplement, often marketed to improve circulation and reduce swelling.

Grapes are widely grown and cultivated for a variety of uses such as for food and beverage making (e.g., wine). They also have a long history of use in traditional medicine. The fruit and skin of grapes contain various compounds that are believed to have health benefits, including antioxidants such as resveratrol and flavonoids. These compounds may help to protect cells from damage and are purported to reduce the risk of certain chronic diseases. Grapes and grape products may also have anti-inflammatory properties, which may help to reduce inflammation in the body and potentially improve symptoms of certain conditions. Grape seed extracts are also commonly used as a dietary supplement and are often standardized according to the content of polyphenols or proanthocyanidins.

Ash is a type of tree and is also known as European ash or common ash. It is a large, deciduous tree that is native to Europe and parts of Asia and is widely cultivated in other parts of the world. The ash tree is known for its distinctive bark and its strong, flexible wood.

Hawthorn has been used to treat a variety of conditions, including gastrointestinal discomfort, heart disease, high blood pressure, and chest pain. For its purported blood pressure-lowering abilities, it is thought to work by dilating blood vessels and improving blood flow to the heart. Hawthorn dietary supplements are typically standardized extracts of the berry, leaf and flower of the plant.
