Overview
Not iodized salt in a capsule, Life Extension Sea-Iodine supplies iodine from a blend of organic marine algae such as kelp. Each easy-to-swallow vegetarian capsule supports healthy iodine levels without adding sodium.
Getting iodine without extra salt is the whole point, and the seaweed source suits people who prefer food-based minerals. The two-bottle pack lasts a long time. The dose per capsule is substantial, which is not right for everyone with thyroid issues.
Who it's for
Suited to health-conscious adults on low-salt diets who want thyroid and adrenal support from sea vegetables. People on thyroid medication should get medical guidance before starting.
Pros and cons

Performance notes
Seaweed concentrates iodine from seawater, so the capsule delivers it in a food-based form. Because the body needs only small amounts, the dose matters more than timing, and steady use maintains levels.
