What Is Calcium Ascorbate?
Ascorbato de calcio es un buffered form of Vitamin C that combines ascorbic acid (vitamin C) with calcium. This combination makes it less acidic and easier on the stomach than traditional vitamin C supplements. It provides the same immune-boosting and antioxidant benefits but with an added dose of calcium—supporting bone, joint, and cellular health at the same time.

Ingredients and How It Works
Each serving of calcium ascorbate delivers:

- Vitamin C (ascorbate) — supports immunity, collagen production, and antioxidant protection.
- Calcium — contributes to bone strength, muscle function, and nerve signaling.
Calcium ascorbate works by releasing vitamin C slowly in the body, helping maintain higher plasma vitamin C levels for longer. This makes it ideal for individuals who are sensitive to acidic vitamin C forms or have gastrointestinal issues.
