Calcium L-Threonate is a highly bioavailable calcium salt of L-threonic acid, a metabolite of Vitamin C. It is recognized as one of the most effective calcium supplements due to its superior intestinal absorption rate and cellular uptake compared to traditional forms like calcium carbonate or citrate.
Unlike other calcium sources, Calcium Threonate bypasses many absorption issues, making it ideal for supporting bone density, joint strength, and healthy aging. It is widely used in nutraceuticals, functional foods, and clinical research on osteoporosis prevention.
🦴 Bone & Joint Support – Promotes calcium deposition in bone tissue
⚡ Superior Absorption – Higher bioavailability than common calcium salts
👵 Anti-Aging Support – Helps maintain skeletal strength in aging populations
💪 Muscle & Nerve Function – Calcium supports neuromuscular regulation
🛡 Synergy with Vitamin C – L-Threonic acid enhances calcium metabolism
≥98% purity verified by HPLC
Better absorption vs calcium carbonate/citrate
Produced under ISO, GMP, and HACCP standards
Low heavy metal content and microbiological safety
Stable crystalline form for supplements & beverages
