Decoding the Double-Calcium Formula
CAC 1000 is a popular calcium supplement, but its name can lead to confusion regarding its actual calcium content. The '1000' refers to the amount of calcium lactate gluconate (1000 mg), not the total elemental calcium, which is the biologically active form of the mineral. By examining the supplement's ingredients, we can precisely calculate the elemental calcium provided per dose.
The Role of Different Calcium Salts
Calcium supplements come in various forms, each with a different percentage of elemental calcium by weight. The CAC 1000 formula is notable for its combination of two distinct calcium salts, which offers a balance of concentration and absorption characteristics.
- Calcium Carbonate: This is a common and highly concentrated form of calcium, containing approximately 40% elemental calcium by weight. It is best absorbed when taken with food, as it requires stomach acid for optimal dissolution.
- Calcium Lactate Gluconate: This is a mix of calcium lactate and calcium gluconate, chosen for its high solubility and bioavailability compared to other forms. While it contains a lower percentage of elemental calcium per milligram, its excellent absorption profile makes it a valuable component of the effervescent formula.
By combining these two forms, CAC 1000 aims to provide both a substantial dose and efficient absorption, particularly in its dissolved, effervescent format.
Calculation of Elemental Calcium in CAC 1000
To determine the total elemental calcium in one CAC 1000 tablet, we must calculate the contribution from each of its two calcium sources. The specific formulation provides:
- Calcium Carbonate: 327 mg per tablet. Given that calcium carbonate is 40% elemental calcium, this contributes $327 \text{ mg} \times 0.40 = 130.8 \text{ mg}$ of elemental calcium.
- Calcium Lactate Gluconate: 1000 mg per tablet. Calcium lactate typically contains about 13% elemental calcium and calcium gluconate about 9%. Since calcium lactate gluconate is a mixture, studies confirm that 2263 mg of calcium lactate gluconate (along with 1750 mg of calcium carbonate) delivers 1000 mg elemental calcium in some effervescent formulations. For CAC 1000, the manufacturers specify a total of 327 mg elemental calcium per tablet, which can be derived by calculating the contribution from the calcium lactate gluconate component based on the known amounts.
Comparison Table: Elemental Calcium in Common Supplements
| Calcium Compound | Elemental Calcium by Weight | Amount in CAC 1000 Tablet | Elemental Calcium per Tablet |
|---|---|---|---|
| Calcium Carbonate | ~40% | 327 mg | ~130.8 mg |
| Calcium Lactate Gluconate | Variable | 1000 mg | ~196.2 mg (Approximate)* |
| Total Elemental Calcium | N/A | N/A | ~327 mg |
*The elemental calcium from the lactate gluconate is an approximation based on the manufacturer's specified total. The exact percentage for the combined salt is not standard and varies by formulation.
Other Key Ingredients in CAC 1000
Beyond the calcium itself, the CAC 1000 formula also includes other nutrients to support overall health and calcium absorption. These typically include:
- Vitamin D3 (400 IU): Essential for the absorption of calcium in the gut. Without adequate Vitamin D, the body cannot effectively use the calcium from food or supplements.
- Vitamin C (500 mg): An antioxidant that plays a role in bone health by contributing to the formation of collagen, a protein that forms the foundation for bones.
- Vitamin B6 (10 mg): Important for various metabolic functions, including protein metabolism which is vital for bone matrix integrity.
How to Maximize Absorption
Taking your calcium supplement correctly is just as important as knowing its content. Here are some tips for maximizing absorption:
- Take with food: Calcium carbonate is best absorbed with a meal, while calcium lactate gluconate is highly soluble and can be taken at any time.
- Dissolve completely: The effervescent format of CAC 1000 ensures the calcium is dissolved and ready for absorption, which can be advantageous over solid tablets.
- Split the dose: The body absorbs calcium most efficiently in doses of 500 mg or less. If you take more than one tablet a day, spread them out to improve absorption.
- Avoid interactions: Certain medications and beverages, such as caffeine and some antibiotics, can interfere with calcium absorption. Always check for potential drug interactions with your healthcare provider.
Conclusion
In summary, one CAC 1000 effervescent tablet contains 327 mg of elemental calcium, not 1000 mg. This amount is delivered through a dual-calcium formula of calcium lactate gluconate and calcium carbonate, supplemented with key vitamins like D3, C, and B6 to enhance absorption and overall benefit. Understanding the difference between total compound weight and elemental calcium is essential for meeting your daily nutritional needs and managing bone health effectively. Always consult a healthcare professional to ensure this supplement is appropriate for your specific health requirements and dosage.

Key Takeaways
- Elemental Calcium Count: A single CAC 1000 tablet contains 327 mg of elemental calcium, despite the '1000' in its name.
- Double-Calcium Formula: The supplement uses a combination of 1000 mg of calcium lactate gluconate and 327 mg of calcium carbonate to deliver its dose.
- Bioavailability: The effervescent, dissolved format improves the bioavailability and absorption of the calcium salts.
- Vitamin Synergy: Vitamin D3 is included in the formula to facilitate calcium absorption, while vitamins C and B6 offer additional health benefits.
- Proper Dosage: Splitting doses of calcium throughout the day can improve absorption, as the body can only process a limited amount at one time.
