Jarrow Formulas® Vitamin D3 (cholecalciferol) may help improve vitamin D status better than equivalent amounts of ergocalciferol (D2).* D3 is also the form produced by skin with UVB exposure (sunlight). Vitamin D3 is converted to its hormonally-active form, calcitriol, in the body as needed. Calcitriol enhances dietary calcium and phosphorous absorption, supports the production of osteocalcin (an important structural protein in bone), and supports a healthy immune response.*

Adults take 1 softgel once a day with a fat-containing meal or as directed by your qualified healthcare professional.

WARNING: Individuals consuming more than 500 mcg (2,000 IU) per day of vitamin D should periodically obtain a serum 25-hydroxy vitamin D measurement. Consult a healthcare professional before using this product if you are pregnant, nursing, under the age of 18, are taking medication or have a medical condition (especially kidney stones or dysfunction, hyperparathyroidism, hypercalcemia, lymphoma, or sarcoidosis); if adverse reactions occur, discontinue use.

Keep out of the reach of children.
