What Is Calcium Ascorbate?

Calcium Ascorbate is a non-acidic form of Vitamin C—a combination of calcium and ascorbic acid. It delivers all the benefits of Vitamin C without the stomach irritation that some people experience with regular ascorbic acid. This makes it a preferred choice for individuals with sensitive digestion or those looking for a buffered, gentle vitamin C source.

Unlike pure Vitamin C (ascorbic acid), Calcium Ascorbate provides both vitamin C benefits and a small calcium boost—making it a two-in-one nutrient that supports immunity, collagen production, bone strength, and antioxidant defense.

Shaanxi Zhonghong Investment Technology Co., Ltd., a leading herbal extract manufacturer and GMP-certified supplier in China, offers high-quality Calcium Ascorbate bulk powder for cosmetics, food, and dietary supplement industries.

Is Calcium Ascorbate the Same as Vitamin C?

Technically, yes—it’s a form of Vitamin C. But Calcium Ascorbate is a buffered, mineral ascorbate, meaning it’s less acidic and often easier on the stomach. It provides the same vitamin C activity—supporting immune function, tissue repair, collagen synthesis, and antioxidant protection—but with better absorption tolerance.

---

Is Calcium Ascorbate Natural or Synthetic?

Most commercial Calcium Ascorbate is synthetically produced from glucose fermentation, followed by neutralization with calcium carbonate. However, reputable manufacturers like Shaanxi Zhonghong use pharmaceutical-grade fermentation and purification processes that ensure high purity and food-grade quality, suitable for functional foods, cosmetics, and nutraceutical applications.

For brands seeking clean-label formulations, Zhonghong also provides customized organic plant extract solutions and GMP-certified production for OEM/ODM projects.

What’s the Difference Between Calcium and Calcium Ascorbate?

• Calcium supports bone health and nerve function.
• Calcium Ascorbate provides both calcium and Vitamin C, enhancing antioxidant and immune benefits while remaining gentle on digestion.

---

Is Calcium Ascorbate Hard on the Stomach?

No. That’s one of its biggest advantages. Unlike ascorbic acid, Calcium Ascorbate is buffered, meaning it’s neutral in pH and gentle for people with sensitive stomachs or acid reflux issues.

What Is the Healthiest Form of Vitamin C?

It depends on your needs:

• Calcium Ascorbate – best for gentle absorption and calcium support.
• Liposomal Vitamin C – for maximum bioavailability.
• Natural Vitamin C extracts (from acerola or camu camu) – for those preferring plant-based sources.

Shaanxi Zhonghong provides both synthetic and natural vitamin C extract options, including Acerola Cherry Extract, Camu Camu Extract, and Calcium Ascorbate bulk powder.

How Much Calcium Is in Calcium Ascorbate?

Each gram of Calcium Ascorbate typically contains about 90–110 mg of elemental calcium, depending on purity.

---

Does Calcium Ascorbate Help with Iron Absorption?

Yes. Vitamin C (including Calcium Ascorbate) enhances non-heme iron absorption by converting ferric iron (Fe³⁺) into ferrous iron (Fe²⁺), which is more easily absorbed by the body. This makes it a good addition to iron-rich diets or supplements.
