Introduction：
Product Name | Calcium L-Threonate |
Appearance | White or almost White Powder |
CAS | 70753-61-6 |
Molecular Formula | C8H14CaO10 |
Molecular Weight | 310.27 |
Purity | 98%min Calcium L-Threonate |
Sample | Available |
Type | Powder & Granule |
Calcium L-Threonate is an important substance in the process of vitamin C metabolism in the body, and has the effect of promoting vitamin C absorption. Pharmacodynamic experiments have proved that calcium L-threonate can increase the amount of bone calcium, bone density and bone strength, and can reverse the negative calcium balance in animals.Most of calcium L-threonate can be absorbed by passive diffusion through the intestinal mucosa, which is an unsaturated absorption process. The passive absorption of calcium is proportional to the intake, the more the intake, the more the absorption.

Function and Application:
1. Calcium L-Threonate has good water-soluble, blood-soluble and fat-soluble properties.
2. Calcium L Threonate is directly absorbed by the human body through the gastrointestinal tract in the state of molecular calcium in the body, which does not increase the burden on the stomach and intestines, and has no toxic side effects on the stomach and intestines, and is a kind of high-quality calcium agent that can easily satisfy the human body's normal demand for calcium.Calcium L Threonate Powder is a commonly used calcium supplement ingredient.
3. Calcium Threonate enters into the plasma calcium with the help of molecular passive diffusion, the proportion of small molecular forms of calcium in total calcium increases, which prolongs the time of calcium metabolism into the plasma, so that the blood calcium has enough time to metabolize with bone calcium, so the bioavailability is high and the effect of calcium supplementation is good.
4. The absorption rate of calcium L-threonate is 95%, which can prevent and eliminate various symptoms caused by calcium deficiency, with high solubility, good absorption and no stimulation to the gastrointestinal tract, which is very suitable for children, pregnant women, lactating mothers, the elderly and other sensitive groups to supplement calcium. Calcium L Threonate capsules and Calcium L Threonate tablets are common forms of calcium supplements.
