Calcium Citrate with Vitamin D: Strong Bones, Healthy Teeth and Muscle Function – Calcium Citrate with Vitamin D3 For Absorption and Mineral Balance

Calcium Citrate with Vitamin D, Life Extension is a dietary supplement formulated to support bone density, dental health and muscle function, through an essential combination of calcium in the form of calcium citrate (200 mg – 15% NRV) and vitamin D3 (cholecalciferol, 2.5 mcg – 13% NRV). Calcium is the main structural mineral of the skeletal system, involved in the mineralization of bones and teeth, but also in a series of vital processes such as muscle contraction, nerve impulse transmission and normal blood coagulation. Vitamin D3 acts as a key regulator of calcium metabolism, contributing to intestinal absorption and maintaining adequate levels of calcium and phosphorus in the blood, essential for skeletal integrity.

With advancing age, periods of sedentary lifestyle, reduced sun exposure or diets low in minerals, the body can become more vulnerable to bone density loss. In such situations, a constant intake of calcium and vitamin D can support the balance between bone formation and resorption, maintaining the resistance of bone structure. Calcium citrate is a valued form for its digestive compatibility and for the fact that it is an organic calcium salt that integrates efficiently into mineral metabolism, often preferred in bone support formulas.

By combining calcium with vitamin D3, Calcium Citrate with Vitamin D aims to offer complete support: not just mineral intake, but also the component that optimizes its use in the body. This synergy is important for active people, for those pursuing long-term prevention, but also for periods when the body's needs increase (stress, intense physical effort, restrictive diet or inconsistent food intake).

 

Detailed Benefits of Calcium Citrate with Vitamin D

 

• Supporting bone density and skeletal strength

Bones are living tissues, in a continuous remodeling process: osteoblasts build new bone, and osteoclasts resorb old bone. Calcium is the basic "brick" of mineralization, and adequate intake supports the maintenance of a solid bone structure. When intake is insufficient, the body can mobilize calcium from bones to maintain vital functions in the blood, which, over time, affects bone density.

Calcium Citrate with Vitamin D can contribute to:
✅ maintaining bone mineralization and skeletal structure
✅ supporting bone resistance to daily mechanical stress
✅ long-term protection against density loss, as part of a prevention routine

This support is especially relevant in periods when mineral balance can be disturbed: diet poor in dairy/calcium-rich foods, sedentary lifestyle, insufficient vitamin D intake, advanced age.

 

• Vitamin D3 – optimizing calcium absorption and efficient mineral utilization

Vitamin D3 is an essential factor for intestinal calcium absorption. Without vitamin D, even a good calcium intake may not be used efficiently. D3 influences calcium transport proteins and contributes to maintaining normal concentrations of calcium and phosphorus, necessary for proper mineralization of bones and teeth.

Vitamin D3 in this formula supports:
✅ calcium absorption and its integration into bone tissue
✅ mineral balance, important for muscle and nerve function
✅ maintaining normal mineralization, especially in periods with reduced sun exposure

This calcium + D3 synergy is a central principle in bone support: intake provides the resource, and D3 supports utilization.

 

• Muscle function and supporting normal contraction

Calcium does not belong only to bones; it is directly involved in the muscle contraction mechanism. In muscle fibers, calcium regulates the interaction between actin and myosin, the elements that allow contraction. Good mineral balance contributes to stable muscle function and better performance in daily activities.

Calcium Citrate with Vitamin D can contribute to:
✅ maintaining normal muscle contraction and coordination
✅ supporting muscle tone, especially in periods of effort or training
✅ more balanced neuromuscular function, through calcium's role in cell signaling

Therefore, the calcium + vitamin D combination is relevant both for sedentary people (who may have lower muscle mass) and for active people (who constantly stress their muscles).

 

• Supporting dental health and enamel structure

Teeth are, structurally speaking, highly mineralized. Calcium, together with phosphorus, forms the basis of hydroxyapatite – the hard mineral that provides strength. A constant calcium intake and balanced mineral metabolism contribute to maintaining dental density and structural strength.

✅ support for tooth health and integrity of mineralized structure
✅ supporting the hard tissues of the oral cavity
✅ maintaining a mineral balance useful for general tooth health

Over time, a good intake of calcium and vitamin D is reflected not only in bones, but also in the body's mineral "reservoir," with an impact on hard tissues.

 

• Support for the nervous system and impulse transmission

Calcium is a key ion in cellular communication. It participates in the release of neurotransmitters at the synaptic level, contributing to nerve impulse transmission. An optimal level of calcium in the blood is crucial, which is why the body strictly regulates circulating calcium.

Calcium Citrate with Vitamin D can support:
✅ normal nervous system function, through calcium's role in signaling
✅ neuromuscular communication and coordination
✅ stability of calcium-dependent physiological processes

This highlights why calcium balance is so important: it influences fundamental processes, not just bone structure.

 

• Calcium citrate – modern form, suitable for daily support

Calcium citrate is an organic salt frequently used in premium supplements, being appreciated for digestive tolerance and its integration into metabolism. For people who seek constant calcium intake, this form represents a practical option, easy to include in a daily routine, especially when diet does not consistently provide necessary minerals.

✅ targeted calcium intake in a form widely used in advanced formulas
✅ constant support for mineral balance
✅ simple formula, with clear synergy: calcium + vitamin D3

 

• Supporting mineral balance in modern lifestyle

Stress, sedentary lifestyle, restrictive diets, reduced consumption of calcium-rich foods and limited sun exposure can contribute to suboptimal status of minerals and vitamin D. In such a context, a supplement that combines calcium and D3 supports an essential goal: maintaining mineral reserves and calcium-dependent functions.

✅ support for prevention and long-term maintenance
✅ relevant for periods with inconsistent food intake
✅ helps maintain a solid foundation for bones, muscles and nervous system

Calcium Citrate with Vitamin D, Life Extension offers an essential combination of calcium citrate and vitamin D3, designed to support bone density, dental health and muscle function, through mineral intake and absorption optimization, contributing to stable mineral balance and body structure vitality.
