Labeled directions — Adults: Take one capsule daily as a dietary supplement, preferably with a meal.

Keep tightly closed in a dry place at 59–86°F. Do not use if the seal is broken or missing. Keep out of reach of children.

This 5,000 IU serving exceeds the general adult daily upper limit of 4,000 IU from all sources. Use this amount under healthcare professional guidance. Tell your healthcare professional about medicines and other supplements you take.

What does vitamin D3 do?

Vitamin D supports calcium absorption, normal muscle function and immune function.†

Is 5,000 IU the right amount for me?

Not everyone needs this amount. It is above the general adult daily upper limit of 4,000 IU. A healthcare professional can assess your needs and guide your dose and duration.

Does this product contain gelatin?

Yes. The label lists gelatin from the capsule, so this product is not suitable for a vegan routine.
