Uses:
L-Threonic acid calcium salt, also known as Calcium L-threonate (CAS No.: 70753-61-6), is a calcium aldonate formed by the combination of L-threonic acid and calcium ions. It is widely recognized as a high-quality calcium supplement and nutritional fortifier. The compound is typically found as a white, odorless, and almost tasteless granule or powder that is highly soluble in water. Notably, it is a natural degradation product of L-ascorbic acid (Vitamin C) and is widely present in plants, human gastric acid, and urine.
Here are the primary uses and key selling points of L-Threonic acid calcium salt:
Key Uses
Nutritional Fortifier & Calcium Supplement: It is extensively used as a safe and effective calcium source in food and beverage industries, including dairy products, beverages, candies, and functional foods, complying with national nutritional fortification standards.
Pharmaceutical Applications: It serves as an active ingredient in anti-osteoporosis drugs and is used as an intermediate in the synthesis of antibiotics (such as erythromycin) and other medications.

Cosmetics: It can be utilized as a moisturizer and antioxidant to help improve skin conditions.
Key Selling Points
Superior Bone Health Support: As a premium calcium source, it effectively promotes bone growth, maintains bone density, and helps prevent/treat osteoporosis and fractures. It has been shown to inhibit osteoclast bone resorption in vitro.
Enhanced Absorption & Bioavailability: The calcium in this compound exists in a small-molecule form that enters the bloodstream through passive molecular diffusion. This increases blood calcium concentration and provides ample time for bone calcium absorption and metabolism.
Promotes Vitamin C Absorption: Studies indicate that Calcium L-threonate can stimulate the cellular uptake of ascorbic acid (Vitamin C), offering a synergistic health benefit.
Antioxidant & Anti-inflammatory Properties: It helps scavenge free radicals, reduce oxidative stress, and alleviate inflammatory responses, thereby protecting cells from damage.
Cardiovascular & Neuromuscular Benefits: It supports cardiovascular health by potentially lowering blood pressure and reducing atherosclerosis risks. Additionally, it plays a crucial role in regulating neuromuscular conduction and promoting blood coagulation.
Excellent Physical & Chemical Stability: It possesses outstanding thermal stability (stable up to 200°C), high resistance to acids and alkalis, and excellent water solubility, making it highly versatile for various manufacturing and processing conditions.
