98% Calcium L-Threonate Powder CAS 70753-61-6
What is calcium threonate?
L-Calcium Threonate has excellent water solubility, blood solubility, and lipid solubility. Clinical studies in traditional Chinese medicine have shown that L-Calcium Threonate can promote the absorption of vitamin C in the body and extend its metabolic duration. It is primarily used for calcium supplementation. Additionally, pharmacodynamic experiments have confirmed that L-Calcium Threonate significantly increases bone calcium content and bone density, thereby enhancing bone strength and reversing calcium negative balance.
Advantages of Calcium Threonate Compared to Other Calcium Sources
Calcium Threonate offers significant advantages over other calcium sources. The effectiveness of calcium supplementation is not determined by the intake amount but by how well the calcium is absorbed. Most calcium supplements on the market are ionic calcium, which requires stomach acid to dissociate into soluble calcium ions. These ions must then bind to "calcium-binding proteins" in the intestine before they can be absorbed. However, due to the body's limited stomach acid secretion and the short transit time of calcium in the gastrointestinal tract, excess calcium is often excreted, leading to low absorption rates—one of the main reasons many people struggle with ineffective calcium supplementation.
In contrast, L-Calcium Threonate is absorbed directly through the gastrointestinal tract in its molecular calcium form, without relying on stomach acid dissociation. This eliminates gastric burden and has no toxic side effects. This unique property makes it a high-quality calcium supplement that efficiently meets the body's calcium needs, offering superior absorption and significantly better calcium supplementation results.
Absorption Efficiency
L-Calcium Threonate is absorbed directly by the intestines in its complete molecular form through an unsaturated absorption process. Its passive calcium absorption is proportional to intake—meaning the more consumed, the more absorbed. L-Calcium Threonate enters the bloodstream via molecular passive diffusion, increasing the proportion of small-molecule calcium and extending its metabolic duration in plasma. This allows sufficient time for calcium exchange between blood and bones, resulting in high bioavailability and significant calcium supplementation effects.
Medical studies have shown that L-Calcium Threonate has an absorption rate of up to 95%, making it highly effective in preventing and alleviating calcium deficiency-related symptoms. With its high solubility and superior absorption, it does not cause any irritation to the gastrointestinal tract, making it particularly suitable for children, pregnant women, breastfeeding mothers, and the elderly, as well as other sensitive groups.
