Marine Calcium Background and Benefits
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. Lactose intolerance is most common in people who aren’t of Indo-European descent. 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
Marine sources of calcium are being used with increasing frequency in dietary supplements. Marine calcium, also known as coral calcium, comes from limestone deposits along the coast, which are mostly composed of fossilized coral reefs. Calcium carbonate (CaCO3) is the primary component of marine calcium, although it also contains magnesium and other minerals in trace amounts.
Aquamin® TG Marine Calcium is a source of calcium that has a high degree of availability. It comes from fossilized seaweed in the Lithothamnion genus, including L. calcareum, L. corallioides and L. tophiforme. This seaweed is harvested from the seabed in the North Atlantic, primarily off the west coast of Ireland and northwest coast of Iceland. The seaweed is then processed to ensure exceptional purity.
Uses of Marine Calcium
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.
Digestive health support
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.
Kidney health support
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.
Bone health support
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.
Signs You May Need Marine Calcium
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.
Other Ingredients That May Be Of Interest
Vitamin D3 - Vitamin D3 is one of the five forms of vitamin D and is also commonly known as cholecalciferol and toxiferol. It’s chemically classified as a secosteroid, which is a steroid molecule with an open ring. Vitamin D is biologically inactive and must be converted to calcitriol, which increases the absorption of calcium into the blood.
Magnesium - Magnesium is a chemical element with the atomic number 12. Its biochemical roles generally relate to the interaction between magnesium and phosphate, which makes magnesium essential for all life forms. A magnesium ion is the active site for many enzymes, especially those that deal with the synthesis of adenosine triphosphate (ATP) and deoxyribonucleic acid (DNA).
