Hi Dee Vitamin D3 2000IU Oral Drops is a liquid supplement that provides vitamin D3 in an easily absorbable form. This 10ml solution helps maintain healthy bones, teeth and muscle function by supporting proper calcium absorption and utilization in the body. Vitamin D3 (cholecalciferol) plays an essential role in calcium absorption and bone mineralization. It supports immune system function and helps maintain healthy muscle function. The liquid drop format allows for flexible dosing and may be particularly suitable for those who have difficulty swallowing tablets or capsules. Vitamin D supplementation is often recommended when natural production through sunlight exposure is limited or for those at risk of deficiency.
