Yes, calcium lactate is soluble in water.
Calcium lactate is a highly bioavailable form of calcium, valued for its ease of dissolution and absorption.
Understanding Calcium Lactate Solubility
Calcium lactate is a salt derived from lactic acid and calcium. Its chemical structure allows it to dissolve readily when mixed with water. This property is crucial for its various applications, particularly in nutrition and food science.
The solubility of a substance refers to its ability to dissolve in a solvent (in this case, water) to form a solution. For calcium lactate, this characteristic means it can efficiently disperse in liquid environments, making it an effective compound for supplements and food fortification.
Why is Calcium Lactate More Soluble?
The solubility of calcium lactate is notably higher than that of many other common calcium salts. For instance, it is more soluble in water compared to calcium citrate or calcium carbonate. This enhanced solubility stems from its chemical structure, which allows for better interaction with water molecules.
This superior solubility translates to practical benefits, especially concerning its absorption in the body:
- Quicker Absorption: Because calcium lactate dissolves easily, it can be absorbed more quickly in the small intestine. This rapid dissolution means it spends less time reacting in the stomach, minimizing potential digestive discomfort and maximizing the amount of calcium available for uptake.
- Higher Bioavailability: Its high solubility contributes to its excellent bioavailability, meaning a greater proportion of the calcium consumed is actually utilized by the body.
Practical Implications and Benefits
The solubility of calcium lactate makes it a preferred choice for several applications:
- Dietary Supplements: As a calcium supplement, its high solubility ensures efficient delivery of calcium to the body, supporting bone health and various physiological functions.
- Food Additive (E327): It is widely used in the food industry as a firming agent, thickener, and an ingredient for calcium fortification in products like baked goods, dairy products, and beverages. Its neutral taste and ease of incorporation are significant advantages.
- Medical Applications: It can be used to treat or prevent calcium deficiencies.
Solubility Comparison of Common Calcium Salts
To illustrate the difference, consider the relative solubility of various calcium forms:
| Calcium Salt | Relative Solubility in Water | Key Application |
|---|---|---|
| Calcium Lactate | High | Dietary supplements, food fortification |
| Calcium Citrate | Moderate | Dietary supplements (often for those with low stomach acid) |
| Calcium Carbonate | Low | Most common and inexpensive calcium supplement |
This table highlights why calcium lactate is often chosen when high solubility and rapid absorption are desired.
Key Characteristics of Calcium Lactate

The readily soluble nature of calcium lactate makes it an efficient and versatile source of calcium, ensuring effective delivery and utilization whether in food products or as a supplement.
For more information on calcium and its various forms, you can refer to resources like the National Institutes of Health (NIH) Office of Dietary Supplements. Additional details on its use as a food additive can be found through organizations like the Food and Agriculture Organization of the United Nations (FAO).
