Description

Vitamins D and K with Sea-Iodine is a capsule combining vitamin D3, vitamin K2 and iodine from a marine source, three nutrients that work together to support normal bone health, calcium balance and thyroid function.

  • Combines vitamin D3 and vitamin K2, which work together to support normal calcium handling
  • Vitamin D and K both contribute to the maintenance of normal bones
  • Includes iodine, which contributes to normal thyroid function
  • Capsule format, once-daily use

How to take it: Take one capsule daily with food, or as directed on the label.

Quality note: This is a food supplement, not a medicine. Speak to your doctor before use if you take blood-thinning medication such as warfarin, or if you have a thyroid condition.
