VITAMIN D3 (AS CHOLECALCIFEROL) (100,000 IU/G)

Vitamin D3, scientifically known as cholecalciferol, is a crucial fat-soluble vitamin and prohormone essential for numerous physiological processes. Sourced primarily from lanolin, a natural substance derived from sheep's wool, this highly purified form of Vitamin D3 (100,000 IU/G) offers exceptional potency and bioavailability. Unlike vitamin D2, cholecalciferol is the identical form of vitamin D produced endogenously in human skin upon exposure to ultraviolet B (UVB) radiation, making it highly recognized and utilized by the body. Its foundational role in maintaining calcium and phosphate homeostasis underscores its significance, as it directly influences mineral absorption from the gut. This ingredient is meticulously processed to ensure a stable and consistent powder suitable for various supplement applications, meeting stringent quality standards.

The health benefits of Vitamin D3 extend far beyond its well-known role in bone health. Once ingested, cholecalciferol is hydroxylated in the liver to 25-hydroxyvitamin D [25(OH)D], the primary circulating form, and then further hydroxylated in the kidneys to its active hormonal form, 1,25-dihydroxyvitamin D [1,25(OH)2D], also known as calcitriol. Calcitriol acts on vitamin D receptors (VDRs) found in nearly all human cells and tissues, modulating gene expression. This broad action explains its impact on immune system regulation, where it supports innate and adaptive immune responses by influencing cytokine production and T-cell differentiation, as evidenced by studies linking deficiency to increased susceptibility to infections. Furthermore, research indicates its involvement in cell growth, neuromuscular function, and inflammation modulation, highlighting its systemic importance.

Given its high potency (100,000 IU/G), this Vitamin D3 powder is ideal for formulating concentrated dietary supplements, including capsules, tablets, and powdered blends, where precise dosing and stability are critical. Quality considerations for cholecalciferol include ensuring pharmaceutical-grade purity, absence of heavy metals, and consistent potency as verified by HPLC analysis. Scientific research consistently demonstrates the widespread prevalence of vitamin D insufficiency globally, making supplementation a vital strategy for public health. Clinical trials have shown that adequate vitamin D levels are associated with reduced risk of osteoporosis, improved muscle strength, and enhanced immune function. For instance, a meta-analysis published in the British Medical Journal highlighted the significant role of vitamin D supplementation in reducing the risk of acute respiratory tract infections. Its integration into formulations often includes co-factors like Vitamin K2 and magnesium, which synergistically support bone mineralization and cardiovascular health, optimizing overall efficacy.
