Calcium is a chemical element with the atomic number 20. It is an essential nutrient for all organisms, primarily for cell signaling and structural components. The movement of calcium ions to and from the cytoplasm of a cell regulates many cellular processes. Calcium is also used to strengthen materials such as bones, shells and teeth.
Calcium is the most abundant metal in most animals, including humans. Virtually all of the calcium in the human body is in the bones and teeth, and about one percent is used by cellular processes such as the release of neurotransmitters and regulating muscle contractions.
Many dietary sources of calcium exist, although they may present problems with assimilating the calcium. For example, dairy products are high in calcium, but many people are lactose intolerant. This condition prevents an individual from eating more than about a half liter of non-fermented dairy products in a serving. Many people are also allergic to dairy products.
Leafy green vegetables such as chard, collard greens, spinach and rhubarb also have a high calcium content, but they may also contain significant levels of oxalic acid. This organic acid can bind to calcium to form calcium oxalate, which inhibits the absorption of calcium in the bloodstream.
Aquamin® TG Marine Calcium has a high degree of availability, easily absorbed by the human body. It is derived from 100% mineralized seaweed in the Lithothamnion genus, harvested from the seabed in the pristine waters off northwest coast of Iceland. This calcium is 100% natural and lactose free.
The uses of marine calcium in health supplements is primarily related to its role as a major component in bones. It can also support menstruation, kidney health and digestive functions.
Calcium carbonate is an alkalizing agent that can neutralize excess stomach acid. This property may make marine calcium useful as an antacid.
Calcium’s role in cellular signaling may help to manage the symptoms of pre-menstrual syndrome (PMS) such as bloating, discomfort, food cravings and mood swings. This is most useful for women with a low dietary intake of calcium.
Marine calcium may be helpful for managing the level of phosphates in the blood. This effect is most likely to help people with poor kidney function, which can result in high serum phosphate levels.
Marine calcium may help to manage the loss of bone mass that typically occurs with age. This benefit is especially helpful for post-menopausal women with high rates of bone loss.
The most common signs that you may benefit from marine calcium supplements include muscle tremors, which may progress to involuntary contractions in severe cases. Additional signs that you may need marine calcium include a loss of bone mass and abnormal heart rhythms.
You may need marine calcium if you want to maintain healthy bone mass and healthy teeth, if you are going through menopause, have a vitamin D deficiency, chronic kidney disease or poor function of the parathyroid gland.
Some of these emails/questions have been published in earlier issues of Xtend-Your-LIfe in which I have tended to dismiss coral calcium as being over hyped and poor value for money. My view on it being over hyped has not changed and I feel that th...
Vitamin D3 Vitamin D3, known chemically as cholecalciferol, is one of vitamin D’s five forms. It is chemically classified as a secosteroid, meaning that it is a steroid with an open ring. The American biochemist Elmer McCollum discovered a factor in cod liver oil that cured rickets in dogs in 192...
