Sentinel Vitamin D3 10,000 IU is a high-potency dietary supplement containing 100 capsules. Each capsule provides 10,000 IU of vitamin D3 (cholecalciferol) to support bone health, immune function, and calcium absorption in the body. This supplement is particularly beneficial for individuals with limited sun exposure, those with increased vitamin D needs, or those who have been diagnosed with vitamin D deficiency under medical supervision. The capsules come in a dark amber bottle to protect the vitamin D from light degradation. As with any high-dose vitamin D supplement, this product should be taken as directed by a healthcare professional.
