Nano hydroxy apatite calcium supplementing agent

Abstract

Hydroxy apatite is prepared into 5-800 nm size hydroxy apatite calcium supplementing agent with hydroxy apatite content of 5-80%. The calcium supplementing agent contains also organic acid, starch, sugar, vitamins and trace elements. It may be produced into various dosage forms, including oral liquid, injection, beverage, food additive, ion implanting transdermal preparation, etc. for meeting the requirement of different people.

Description

technical field [0001] The invention relates to a health product using nano-scale hydroxyapatite as a calcium supplement. Background technique [0002] Calcium is the most abundant and one of the most important mineral elements in the human body. It plays an important role in maintaining the normal functions of the human body such as breathing, nerves, digestion, endocrine, urinary, and immunity. [0003] Current medical research shows that no matter the third world, or developed countries such as the United States, Europe, and Japan, calcium deficiency is relatively serious. For Chinese residents, since the current daily diet is still mainly plant-derived food, the calcium contained in plant food is not easily absorbed by the human body. Calcium deficiency is very widespread and has become a very common social problem. There are 80 million people diagnosed with osteoporosis in my country; among the 95 million children under the age of 3 in the country, the incidence of cal...

Problems solved by technology

However, the particle size is too coarse, generally in the order of μm, which is not conducive to the absorption of calcium by the human body; Chinese invention patent 98117505.8 uses calcium acetate, calcium lactate, calcium citrate, calcium gluconate, calcium threonate, and calcium for hydrocarbon oil Composite decalcifying agent has the disadvantage of insufficient calcium content, which cannot reach the dose of calcium supplementation; Chinese invention patent 93106178.4 uses marine biological oysters and shells as raw materials for calcium extracts. Although its production process is simple and low in cost, its products Contains environmental pollutants in the ocean, and its calcium content is insufficient and the particle size is too coarse to meet the body's absorption of calcium

Studies have proved that the highest bioavailability of various active calcium in the international market is only 30%; and the composition is complex, and compounded with certain ingredients that affect calcium absorption, such as oxalic acid; especially containing a large amount of calcium salts and being too alkaline, greater stomach irritation
