Jarrow Formulas® Vitamin D3 provides cholecalciferol, which is the form produced by the (human) skin in response to UVB exposure (sunlight) and may also improve vitamin D status better than equivalent amounts of ergocalciferol (D2).* Vitamin D3 is ultimately 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.*

Suggested Use:

For adults, take 1 softgel daily or every other day with a fat-containing meal or as directed by your qualified healthcare professional.

NOTE: Individuals consuming more than 2,000 IU/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 trying to conceive, pregnant, or lactating, under the age of 18, or have a medical condition (especially kidney stones or dysfunction, hyperparathyroidism, hypercalcemia, lymphoma, or sarcoidosis); if adverse reactions occur, discontinue use.

Keep out of reach of children.
