Other Common Names for Calcium Ascorbate
While the chemical name is calcium ascorbate, it is often referred to by several other names in the supplement industry and broader health context. Understanding these different monikers helps consumers and health professionals navigate product labels and scientific literature with greater clarity.
Mineral Ascorbate
This is a general term that applies to calcium ascorbate, as it is a compound that contains both a mineral (calcium) and vitamin C (ascorbate). The ascorbate portion is the vitamin C component, while the calcium serves to neutralize the acid. This buffering process is what makes it distinct from standard ascorbic acid.
Ascorbic Acid Calcium Salt
This is a more technical but very descriptive name for the compound. It accurately describes its chemical composition: a salt formed when ascorbic acid reacts with calcium carbonate. The resulting compound is chemically neutral, with a pH that is much easier on the digestive system compared to the acidic pH of ascorbic acid.
Ester-C
One of the most well-known aliases for calcium ascorbate is Ester-C. While the proprietary blend of Ester-C includes additional compounds like calcium threonate, its primary active ingredient is buffered calcium ascorbate. Many people use the brand name Ester-C interchangeably with calcium ascorbate due to its popularity in the market for non-acidic vitamin C supplements.
E 302
In the food industry, calcium ascorbate is identified by its European food additive code, E 302. It is used as a preservative and antioxidant to prevent oxidation and browning in processed foods and beverages.
Benefits and Applications of Calcium Ascorbate
Calcium ascorbate offers the essential benefits of vitamin C in a form that is more accessible to individuals with sensitive digestive systems. Here are some of its key functions:
- Immune System Support: Like other forms of vitamin C, it enhances immune function by supporting white blood cell activity.
- Gentle on the Stomach: As a pH-neutral, buffered form, it is less likely to cause gastrointestinal issues like heartburn or diarrhea, which can be side effects of high-dose ascorbic acid supplementation.
- Bone and Tissue Health: The calcium component contributes to maintaining strong bones and teeth, while the vitamin C is essential for collagen production, which supports healthy skin, cartilage, and ligaments.
- Antioxidant Protection: It functions as a powerful antioxidant, protecting the body's cells from damage caused by free radicals.
- Enhanced Iron Absorption: Vitamin C is known to improve the absorption of non-heme iron (the type found in plant-based foods), and calcium ascorbate provides this same benefit.
Comparison: Calcium Ascorbate vs. Ascorbic Acid
To better understand the value of calcium ascorbate, it's helpful to compare it directly with the more common form of vitamin C, ascorbic acid.
| Feature | Calcium Ascorbate | Ascorbic Acid |
|---|---|---|
| Acidity | pH-neutral and non-acidic, making it gentle on the stomach. | Highly acidic, which can cause digestive upset in some individuals. |
| Composition | A salt of ascorbic acid, combined with calcium. Provides both vitamin C and calcium. | The pure, unadulterated form of vitamin C. |
| Cost | Generally slightly more expensive due to the additional processing to add calcium. | More affordable and widely available. |
| Target User | Recommended for individuals with sensitive stomachs, chronic digestive issues, or those who require extra calcium. | Suitable for those who tolerate acidic foods and drinks well, and prefer a straightforward vitamin C supplement. |
| Effectiveness | Bioavailability is comparable to or potentially higher than standard ascorbic acid, especially for sustained release. | Equivalent bioavailability to calcium ascorbate at lower doses. |
Synthesis and Manufacturing
Calcium ascorbate is manufactured through a specific process to ensure its buffered nature. Typically, it is produced by dissolving ascorbic acid in a solution and reacting it with a calcium source, such as calcium carbonate. This reaction neutralizes the acidic component of the vitamin, creating a stable, crystalline powder that is gentler on the digestive tract.
Using Calcium Ascorbate
As with any supplement, consulting with a healthcare professional or following the directions on the product label is recommended before use. While calcium ascorbate is generally well-tolerated, excessive intake of vitamin C in any form can lead to side effects such as diarrhea. High intake of calcium could potentially lead to issues like constipation or, in rare cases, kidney stones.
It is always recommended to obtain vitamins from a balanced diet primarily, with supplements used to fill nutritional gaps. For those with pre-existing kidney disease or other medical conditions, it is especially important to speak with a doctor before beginning any new supplementation regimen.

Conclusion
In summary, what is calcium ascorbate also known as? It is known by several names, most notably buffered vitamin C, mineral ascorbate, and the popular brand name Ester-C. It is the calcium salt of ascorbic acid, which is synthesized to be a less acidic, more stomach-friendly alternative to traditional vitamin C supplements. Its benefits extend beyond simple vitamin C supplementation by providing an additional source of calcium, supporting bone health, and offering potent antioxidant protection. For individuals with sensitive stomachs or those who find pure ascorbic acid irritating, calcium ascorbate provides an excellent way to maintain a healthy vitamin C intake without discomfort.
