Key Benefits of Calcium and Vitamin D

• Bone health: Calcium provides the building blocks for bones, while vitamin D enhances its absorption to help maintain bone density as you age.
• Immune function: Vitamin D contributes to a healthy immune system, supporting your body's defences against seasonal challenges.
• Muscle function: Adequate levels of both nutrients are essential for normal muscle contraction and coordination.
• Convenient potency: Each tablet delivers 1000 mg of calcium (as calcium carbonate) and 800 IU of vitamin D3 (cholecalciferol), the preferred form for bioavailability.

Why Combine Calcium and Vitamin D?

Discover 21St Century Calcium, — Calcium and vitamin D work synergistically to promote strong bones and overall health. Vitamin D is crucial for efficient calcium absorption, making this duo vital for maintaining bone density and muscle function. A significant portion of the population does not get enough of these nutrients, particularly during winter months or with limited sun exposure. This supplement provides 1000 mg of calcium per serving plus 800 IU of vitamin D—double the amount in many standard formulas—to help fill nutritional gaps.

Who Might Benefit from This Supplement?

Individuals with limited sun exposure, such as those living in northern climates or spending most of the day indoors, may need additional vitamin D. Older adults, postmenopausal women, and those with lactose intolerance or dairy-free diets often require supplementary calcium as well. This product is suitable for anyone seeking a higher vitamin D intake without taking multiple pills.

Safety and Side Effects

Calcium and vitamin D are generally safe when taken as directed. Excessive calcium intake may cause constipation or interact with certain medications. Very high doses of vitamin D over extended periods can lead to toxicity. Consult a healthcare practitioner if you are pregnant or breastfeeding, or if you have existing health conditions or take prescription drugs. Always read the label and follow directions for use.
