Life Extension Vitamin D3 with Sea-Iodine
125 mcg (5,000 IU) of vitamin D3 and 1,000 mcg of iodine in one daily capsule for bone, immune and thyroid support
Vitamin D3 with Sea-Iodine is Life Extension's once-daily capsule for bone, immune and thyroid support. One capsule gives you 125 mcg (5,000 IU) of vitamin D3, 625% of the Daily Value, and 1,000 mcg of iodine, 667% of the Daily Value.
Vitamin D helps your body absorb calcium for strong bones, and your immune system needs it too. Your thyroid uses iodine to make its hormones, which is why Life Extension adds it for people who don't eat much seafood or iodized salt. The iodine comes from its Sea-Iodine blend of organic kelp and bladderwrack extracts with potassium iodide. Each bottle holds 60 capsules, a 60-day supply, and it's gluten free and non-GMO.

How to use it
- Take 1 capsule once a day with food.
- Life Extension suggests a 25-hydroxy vitamin D blood test after about 3 months to see where your levels are.
If you get more than 50 mcg (2,000 IU) of vitamin D a day from food and supplements, Life Extension says to have your vitamin D level checked from time to time, and not to go over 10,000 IU a day unless your doctor recommends it. One capsule is above NIH's 100 mcg (4,000 IU) daily upper limit for adults, and its 1,000 mcg of iodine is close to NIH's 1,100 mcg limit, so check with your doctor if you take other vitamin D or iodine, such as a multivitamin or kelp. Don't use it if you have high blood calcium levels. If you have a thyroid condition or take antithyroid medicine, talk to your healthcare practitioner first. Talk to your physician if you're pregnant or nursing or have a medical condition. Keep out of reach of children.
A good fit if you
- Want vitamin D3 and iodine in one daily capsule
