D3-4 Cholecalciferol by Bio-Tech Pharmacal is an easy way to fit vitamin D into your daily regimen. Vitamin D can play several important roles in general health. First‚ it may work to maintain strong bones and teeth by supporting calcium absorption. At the same time‚ this vitamin might offer support for optimal immune function because of its potential to encourage increased white blood cell production.
Every capsule of D3-4 Cholecalciferol provides 4‚000 IU (international units) of vitamin D3‚ which is chemically identical to the form of vitamin D that the human body produces when skin is exposed to natural sunlight. Furthermore‚ unlike most vitamin D supplements (which are fat-soluble)‚ D3-4 Cholecalciferol contains a dry‚ water-soluble preparation of vitamin D3. As a result‚ people who have trouble digesting fats may find this product easier to absorb.
At the recommended dosage of one capsule daily‚ each 250-capsule bottle of Bio-Tech Pharmacal’s D3-4 Cholecalciferol should last for more than eight months.
