Coolkin High Potency Vitamin D3 50,000 IU Capsules

A concentrated, single-ingredient dose. Each capsule delivers 1250 mcg (50,000 IU) of cholecalciferol, the same form of Vitamin D3 the body produces from sunlight, formulated for adults who need more than a standard daily amount.

Use only as directed. This is a high-potency formula intended for use only as directed on the label or by your healthcare provider. Vitamin D can accumulate to toxic levels with excessive or prolonged use, so anyone considering a high-dose regimen — especially alongside calcium supplements or while managing a kidney condition — should consult a healthcare provider before starting.

Verified manufacturing. Produced in a GMP-certified facility in the USA and backed by CFDA certification, with quality standards applied to every batch.
