Life Extension Vitamin D3 with Sea-Iodine - Bone, Brain & Thyroid Support

Vitamin D3 with Sea-Iodine™ delivers dual-action support for your bone health, thyroid health, and immune health. This formula's 125 mcg (5,000 IU) of vitamin D3 promotes the transport of calcium into bones, encourages cognitive function, and plays a critical role in healthy immune function. Iodine supports healthy thyroid function—but many people don't get enough. So we've combined them into a single, convenient supplement.

Two nutrients in one – Iodine is a trace element with important biological roles. Vitamin D3 is an important nutrient for whole-body health. Because many people struggle to get enough of these nutrients, we've combined them into a single supplement.

Bone, brain & immune health – Vitamin D helps your bones maintain their strength and rigidity. It supports cognitive health, especially as you age. Vitamin D3 also supports immune function and endothelial health.

Trace element essential for life – Iodine supports the production of thyroid hormones. A healthy thyroid gland acts as your body's thermostat, helping to regulate your metabolism, including when and how you burn fat for energy.

Ingredients matter – We use only the finest raw ingredients with the purity and potency you deserve. The majority of our products are non-GMO, gluten-free, and manufactured in the USA—and a Certificate of Analysis is available for every one.

Live your healthiest life – We believe the answers to a healthier life are within reach, and that scientific research is the key to getting us there. That's why so many of our formulas feature specific ingredients and amounts based on scientific studies.
