Vitamin D3, or cholecalciferol, is one of the two main variants of vitamin D, a fat-soluble vitamin now available to buy at Supersmart. It is present in nutritional supplements in the forms D2 (ergocalicferol) and D3. In the liver, both are converted into 25-hydroxy-vitamin D, or 25(OH)D. Over the last 10 years, research has demonstrated that vitamin D may offer a number of additional health benefits when given at the right dose.
Vitamin D3 is generally well-tolerated in adults at daily doses up to 2000 IU. Several studies suggest it may be safe even at doses up to 10,000 IU/day, although health authorities have set the safe upper limit at 1000 IU/day. Scientists, however, believe a healthy adult needs close to 1000 IU/day. This dosage is available to buy at Supersmart.
This product’s softgels are of bovine origin. They are particularly suitable for supplements that require rapid solubility. Made from high-quality bovine gelatine, they are safe and effective.
