Key Benefits

  • Promotes optimal vitamin D levels.
  • Supports bone and immune health.
  • Helps maintain healthy iodine levels for proper thyroid function.


Vitamin D3 is a crucial fat-soluble vitamin that supports overall health. The body naturally produces it when exposed to sunlight. Vitamin D3 is essential for strong bones, as it helps the body absorb calcium. It also boosts the immune system, protecting against infections and diseases, and may improve mood and support a healthy inflammatory response. But some people may still not get enough vitamin D due to limited sun exposure or their diets- which makes supplementation essential.

Life Extension's Vitamin D3 with Sea-Iodine delivers 125 mcg (5,000 IU) of Vitamin D3 per serving, ensuring optimal levels for daily health needs. It also includes 1,000 mcg of iodine to complement the Vitamin D3, addressing potential iodine deficiencies in those with limited dietary intake. Iodine is vital for producing thyroid hormones, which regulate metabolism and energy use. Together, these nutrients work to promote whole-body health and wellbeing.
