Life Extension Sea-Iodine Capsules

Our verdict

Life Extension Sea-Iodine Capsules works out to $0.10 per serving of iodine, at 1000mcg per serving in capsule form. That puts it around the median of the 21 iodine products we can price per dose, where the typical serving costs $0.05, a Value Index of 0.5 where the median product is 1.0. One container lasts 150 days at the label dose of 1 serving a day, about $3.14 a month. We could not verify a third-party certification for Life Extension in a public registry.
