Vitamin D3 Cholecalciferol 4millionIU/G

Vitamin D3 Cholecalciferol 4 million IU/g is a highly concentrated form of vitamin D3 used primarily in pharmaceutical and supplement manufacturing.

Appearance: White columnar crystals or crystalline powder, odorless and tasteless.

Solubility: Practically insoluble in water; freely soluble in ethanol, fatty oils, and solvents such as chloroform and ether

Melting Point: 83–86 °C

The vitamin D3 from this powder is efficiently absorbed in the intestines, helping maintain optimal serum levels to support bone health and prevent diseases such as rickets, osteomalacia, and osteoporosis.

Vitamin D3 Cholecalciferol 4 million IU/g offers several significant health benefits primarily related to its role as the active form of vitamin D in the human body:

1. Bone Health: It enhances calcium and phosphate absorption in the gut, vital for bone formation, mineralization, and maintaining bone density. High-dose vitamin D3 supplementation helps reduce risks of rickets, osteomalacia, osteoporosis, and fractures, especially in older adults. It promotes collagen fiber production and improves bone material properties, supporting peak bone mass and skeletal strength.

2. Immune System Support: Vitamin D3 modulates immune function by enhancing antimicrobial peptide production, helping the body fight infections, reducing inflammation, and potentially lowering risks of autoimmune diseases.

3. Muscle Function: It supports muscle strength and function, reducing weakness and risk of falls in vulnerable populations such as the elderly.

4. Cardiovascular and Metabolic Benefits: Vitamin D3 plays a role in regulating blood pressure, inflammation, and vascular health, contributing to cardiovascular protection. Some studies also indicate improvement in glycemic control and metabolic health with supplementation.

5. Neuroprotective and Cognitive Effects: Emerging evidence suggests potential benefits in brain health, reducing neuroinflammation and supporting neurological function, though clinical data are still mixed.

6. Safety and Dosing: Despite the very high potency of the 4 million IU/g form used for pharmaceutical manufacturing, high-dose regimens (e.g., 300,000 to 500,000 IU single doses) have been shown safe and effective for raising serum vitamin D levels under medical supervision, with low toxicity risk when monitored appropriately
