Private Label Calcium Carbonate 500mg & Vitamin D 50 IU

Calcium is the body’s most abundant mineral, with more than 99% stored in bone and teeth as mineralized structure. The circulating ionized fraction also participates in muscle contraction, nerve transmission, vascular function, coagulation, and hormonal secretion. Vitamin D supports active intestinal calcium transport, making the combination mechanistically complementary; calcium carbonate also provides approximately 40% elemental calcium by weight.

To ensure that Cpack Manufacturing is providing a consistent calcium and vitamin D product, the formula uses the defined 500 mg calcium carbonate and 50 IU vitamin D strengths stated on Cpack’s product page. Final Supplement Facts should distinguish the calcium compound weight from the verified elemental calcium declaration required for label accuracy.

The main benefits provided by our Private Label Calcium Carbonate 500mg & Vitamin D 50 IU supplements are as follows:

• Calcium Carbonate 500 mg — A calcium salt containing about 40% calcium by weight; the finished label should declare verified elemental calcium rather than infer it from compound weight alone.
• Vitamin D 50 IU — A complementary vitamin D dose that supports active intestinal calcium transport through vitamin D receptor-regulated pathways.
• Bone Hydroxyapatite — Most body calcium is stored in skeletal hydroxyapatite, where calcium and phosphate provide structural rigidity to bone and teeth.
• Muscle Contraction — Ionized calcium participates in excitation-contraction coupling and is required for normal skeletal, smooth, and cardiac muscle function.
• Nerve & Secretory Signaling — Calcium ions act as intracellular signals involved in neurotransmitter release, nerve communication, and hormone secretion.
• Active Calcium Absorption — Vitamin D promotes transcription of proteins involved in active transcellular calcium absorption in the intestine.
