Calcium (Ca2+) is naturally presented in water. It dissolves from rocks that can be found in water Calcium can be present in different forms that vary in their chemical properties and bioavailability. Calcium is present in teeth, bones, muscle tissue, and in the blood. Calcium has many functions in the body such as stabilizing the pH of the body, it is necessary for muscle function, vascular contraction, nerve transmission, providing structural material to the bones and teeth, decreasing the risk of osteoporosis. The internal Calcium balance is determined by vitamin D and parathyroid hormone. The recommended daily intakes of Calcium vary from 400 to 1200 mg per day depending on the environment, sport level, size age, and gender. Calcium should never be eaten with food rich in iron such as red meat because Calcium affects iron absorption. There are a lot of calcium forms, but in this article, we will present 8 forms of calcium.
Calcium carbonate is an alkaline, found in bones of animals and eggshells. The bioavailability of this type of calcium is low and it’s hard to be digested. Soluble on an acidic environment, that’s why this type of calcium pushes the stomach to produce more acid, and that may be applied to resolve digestive failure if a person has less with stomach acid but if a person has much stomach acid, then another type is better choice such as Calcium Citrate. Calcium carbonate should be taken with a meal. Calcium Carbonate induced a decrease in the Parathyroid hormone level and has less urinary excretion of Ca than calcium citrate malate. Calcium Carbonate may be useful in inhibiting the release of calcium from bone stores.
Calcium citrate is the calcium salt of citric acid, found in food rich in citric acid such as Limes and in Grapefruit, which has a moderate bio-availability value, which means it doesn’t need to be taken with food because it is sparingly soluble in water.
Doctors use it as medication in the form of an injection to treat magnesium toxicity, osteoporosis, calcium deficiency. This type of calcium must be used under the supervision of doctors because can give negative Side effects such as kidney stones. Calcium gluconate is made by mixing gluconic acid with calcium carbonate or calcium hydroxide.
Calcium lactate can be prepared by a combination of lactic acid with calcium carbonate or calcium hydroxide. Can be found also in aged cheese and baking powder, soluble in water.
Calcium Phosphate express to a family of minerals containing calcium ions. Found in milk, rocks, and coral sea, it exists in the form of hydroxyapatite in bones and teeth. is required for bone and teeth structure.
Calcium Citrate Malate
This is the best kind of calcium used to treat low blood calcium, osteoporosis, decreases bone fracture risk in the elderly, decreased activity of the parathyroid gland, a good choice for women who are pregnant, soluble in water, and is the most readily absorbed form. Studies have shown that this type of calcium has the lowest effect on Parathyroid hormone level and greatest urinary excretion of Calcium, that’s why don’t double the recommended dose. The side effect can be dyspepsia and dearies.
Calcium pyruvate is a form of calcium that can help with losing fat by affecting the mitochondrial health of the cells. Can improve exercise capacity, Calcium Pyruvate is involved in ATP energy production, fat and protein metabolism, and glycogen. Calcium pyruvate, increased protein uptake, increased glycogen storage, and cellular respiration. Potentially helping the body utilize fat for energy, spare lean body mass, and increase endurance during exercise. Has negative side effects on gastrointestinal such as dyspepsia, dearie, gas, and bloating. Studies have shown that this type of calcium has less urinary excretion of Calcium than Calcium malate. Can even induce a decrease in the Parathyroid hormone level.
