Understanding Calcium Citrate: What It Is and How It’s Made
Calcium citrate is a popular dietary supplement known for its high bioavailability, meaning it is easily absorbed by the body. But have you ever wondered what calcium citrate is made from and how it is produced? In this article, we will explore the origins of calcium citrate, its benefits, and why it’s a preferred choice for calcium supplementation.
What is Calcium Citrate?
Calcium citrate is a calcium salt of citric acid, which is a naturally occurring acid found in citrus fruits. It is one of the most commonly used forms of calcium in supplements due to its excellent absorption properties. Unlike other forms of calcium, calcium citrate can be taken on an empty stomach, making it a convenient option for many people.
How is Calcium Citrate Made?
Calcium citrate is made through a chemical reaction between calcium carbonate or calcium hydroxide and citric acid. Here is a simplified breakdown of the process:
1. Source of Calcium: The calcium used in making calcium citrate can come from various sources, including limestone (calcium carbonate) or slaked lime (calcium hydroxide). These natural sources provide a stable form of calcium.
2. Citric Acid: Citric acid, the other key ingredient, is often derived from fermentation processes using citrus fruits or other carbohydrate sources. It can also be produced synthetically.
3. The Reaction: When calcium carbonate or calcium hydroxide is combined with citric acid, a chemical reaction occurs, resulting in the formation of calcium citrate along with the release of carbon dioxide (in the case of calcium carbonate). This reaction produces a salt that is highly soluble in water.
4. Purification and Crystallization: The resultant calcium citrate solution is then purified to remove any impurities. After purification, it may be crystallized to achieve a stable and usable form of the compound.
5. Final Product: The final product is a white crystalline powder that can be easily incorporated into dietary supplements, making it accessible to consumers.
Benefits of Calcium Citrate
Calcium citrate offers several advantages, making it a favored choice for those looking to enhance their calcium intake:
– High Absorption Rate: One of the most significant benefits is its high bioavailability. Studies have shown that calcium citrate is absorbed better than other forms of calcium, especially in individuals with lower stomach acid levels.
– No Need for Food: Unlike calcium carbonate, which requires stomach acid for absorption and is best taken with food, calcium citrate can be taken on an empty stomach, providing flexibility in supplementation.
– Less Likely to Cause Gastrointestinal Issues: Calcium citrate is generally gentler on the stomach and less likely to cause constipation or bloating compared to other calcium supplements.
– Supports Bone Health: As a calcium source, calcium citrate plays a crucial role in maintaining bone density and overall skeletal health, especially in postmenopausal women and the elderly.
Conclusion
Calcium citrate is an effective and highly absorbable form of calcium that is made from natural sources through a straightforward chemical process. Its ability to be taken without food and its gentle nature on the digestive system make it an excellent choice for those looking to boost their calcium intake. Whether you’re looking to support bone health or enhance overall wellness, calcium citrate made from quality sources can be a beneficial addition to your dietary regimen. Always consult with a healthcare professional before starting any new supplement to ensure it aligns with your health needs.
By understanding what calcium citrate is made from and its benefits, you can make informed decisions about your health and nutritional choices.
