Life Extension Vitamins D and K with Sea-Iodine is a once-daily supplement designed to support bone, brain, thyroid and vascular health, with 125 mcg (5,000 IU) of vitamin D3 and 1,000 mcg of iodine.
This formula brings vitamins D and K together with sea-iodine for people looking to add these nutrients to a daily routine. Its stated purpose is support for bone, brain, thyroid and vascular health. The once-daily format keeps the product’s use straightforward, while the two-pack supplies two units of the 60-capsule product.
Each formula combines 125 mcg (5,000 IU) of vitamin D3, 2,100 mcg of vitamin K and 1,000 mcg of iodine. These amounts make the nutrient combination clear for shoppers comparing the product with their current supplement routine. The listed health-support purpose covers bone, brain, thyroid and vascular health; the product does not assign a separate health benefit to each individual nutrient.
Life Extension presents this as a once-daily supplement, so it is suited to shoppers seeking a daily formula rather than a product described for multiple daily uses. The available details do not give a capsule count per daily serving, so the once-daily description should not be read as a one-capsule direction.
The brand says it sources raw ingredients with a focus on purity and potency. Life Extension has developed formulas for more than 40 years, using scientific research and current findings as the basis for its approach. These points describe the brand’s stated ingredient and development standards; they do not add a certification or independent testing claim.
This two-pack is suited to adults who want a capsule-based, once-daily supplement combining vitamins D and K with sea-iodine for the stated areas of health support. It offers the specified nutrient amounts in a two-pack of the 60-capsule product.
