Private Label Vitamin D3 5000 IU

Vitamin D3 supports calcium and phosphate metabolism through conversion to calcitriol and vitamin D receptor signaling. A 5,000 IU strength exceeds the adult tolerable upper intake level of 4,000 IU per day, so dosing should be determined with a healthcare professional. For this higher-strength category, accurate cholecalciferol potency is the central quality requirement.

Cpack Manufacturing offers Vitamin D3 5000 IU within its stock softgel range for private label branding. Our quality controls include raw material identity testing, documented manufacturing records, and independent laboratory validation of microbial and heavy metal limits. These safeguards support ingredient traceability and consistent production quality for your brand.

The main benefits provided by our Private Label Vitamin D3 5000 IU supplements are as follows:

• Cholecalciferol — The D3 form provides a labeled strength of 5,000 IU, equivalent to 125 mcg, to supplement dietary vitamin D intake.
• Vitamin D Metabolism — Liver conversion produces 25-hydroxyvitamin D, the principal blood marker of vitamin D status; kidney conversion then produces active calcitriol.
• Bone and Mineral Support — Calcitriol acts through the vitamin D receptor to regulate intestinal calcium absorption and phosphate availability for bone and tooth mineralization.
• Neuromuscular Function — Vitamin D participates in neuromuscular regulation. Its role in calcium homeostasis contributes to normal muscle contraction and nerve function.
• Immune and Cellular Regulation — Active vitamin D influences gene expression through vitamin D receptor signaling, contributing to normal immune function and cellular differentiation.
