檸檬酸鈣(Calcium citrate)在機體的代謝

鈣的吸收主要發生在小腸，通過旁細胞通路和維生素D₃調控的跨細胞通路2個途徑經由跨膜蛋白質上Ca²⁺轉運載體來完成鈣離子轉運。旁細胞途徑是利用腸道和血液中鈣離子濃度的梯度進行被動轉運的吸收途徑，不需要消耗ATP；而跨細胞途徑是鈣離子通過鈣結合蛋白質在相關酶的作用下依賴維生素D₃而被機體主動吸收的一個過程，此過程需要消耗ATP。鈣在腸道的吸收受很多因素影響，如維生素D₃的水平、腸道酸性環境、年齡、雌激素水平以及日糧纖維攝入等。腸道吸收的鈣離子，通過門靜脈進入血液，被運輸到各個器官，包括在骨骼上的沉積。而檸檬酸主要在肝臟、肌肉和腎臟中通過三羧酸循環被分解利用，最終為機體提供能量。檸檬酸鈣主要通過在胃環境中分解出的檸檬酸實現更多的功能。檸檬酸經三羧酸循環，最終生產二氧化碳和水，并產生ATP，為機體提供能量，促進機體生長發育。檸檬酸鈣在胃環境中分解出檸檬酸，可降低胃腸道pH值，有利于激活胃蛋白酶原。檸檬酸鈣對腸胃無刺激作用，可不經胃酸中和而直接被機體吸收，吸收率高。檸檬酸鈣本身的溶解性優于碳酸鈣、磷酸鈣、硫酸鈣等其他鈣源，降解過程中可高效、平穩釋放鈣離子。

Metabolism of calcium citrate in the body

Calcium absorption occurs mainly in the small intestine through two pathways, paracellular pathway and transcellular pathway regulated by vitamin D3, through Ca2+ transporters on transmembrane proteins. Paracellular pathway is an absorption pathway that uses the gradient of calcium ion concentration in the intestine and blood to carry out passive transport without consuming ATP. The transcellular pathway is a process in which calcium ions are actively absorbed by the body through calcium-binding proteins and dependent on vitamin D3 under the action of related enzymes, which requires the consumption of ATP. The absorption of calcium in the gut is influenced by many factors, such as vitamin D3 levels, intestinal acidic environment, age, estrogen levels, and dietary fiber intake. Calcium ions absorbed by the gut, which enter the bloodstream through the portal vein, are transported to various organs, including deposits on the bones. Citric acid is mainly broken down and utilized in the liver, muscles and kidneys through the tricarboxylic acid cycle, and ultimately provides energy for the body. Calcium citrate mainly achieves more functions by breaking down citric acid in the stomach environment. Citric acid through the tricarboxylic acid cycle, and eventually produce carbon dioxide and water, and produce ATP, to provide energy for the body, promote body growth and development. Calcium citrate breaks down citric acid in the gastric environment, reduces gastrointestinal pH, and is conducive to the activation of pepsinogen. Calcium citrate has no irritating effect on the stomach and is directly absorbed by the body without being neutralized by stomach acid, with high absorption rate. The solubility of calcium citrate itself is better than other calcium sources such as calcium carbonate, calcium phosphate and calcium sulfate, and calcium ions can be released efficiently and smoothly during the degradation process.
