UltraVit's Vitamin D3 4000 IU offers a significant dose of this crucial vitamin, known for its widespread benefits across the body's systems. Vitamin D, functioning similarly to a hormone, is vital for immune system functions, maintaining bone and teeth health, supporting cognitive and muscle functions, and reducing tiredness and fatigue. This supplement is packed in 120 easy-to-swallow softgels, ensuring comprehensive support for your health. 


  • Immune System Support: Enhances the body's natural defense mechanisms. 
  • Bone and Teeth Health: Essential for maintaining strong bones and dental health. 
  • Cognitive Function: Contributes positively to brain health and cognitive functions. 
  • Muscle Function: Supports normal muscle function, aiding in mobility and strength. 
  • Energy Boosting: Helps in reducing tiredness and fatigue for overall vitality. 

Vitamin D's role extends beyond basic health maintenance; it is crucial for the absorption and utilization of calcium and phosphorus, maintaining normal blood calcium levels, and even participates in cell division. Given the challenges of obtaining sufficient Vitamin D from sunlight and diet alone, especially in less sunny regions, supplementation becomes essential to meet the body's needs. 


  • High Potency: 4000 IU of Vitamin D3 to meet and exceed daily dietary needs. 
  • Broad Health Benefits: Supports a range of bodily functions from immune defense to cellular health. 
  • Optimal Absorption: Softgel form ensures high bioavailability and effective absorption.
