Life Extension Vitamin D3 with Sea-Iodine, 125 mcg (5000 IU), 60 Capsules

Who May Benefit from This Supplement?

Many individuals do not obtain sufficient vitamin D or iodine from diet and sunlight alone. This supplement is especially suitable for those with limited sun exposure, living in northern latitudes, having darker skin, or following a diet low in iodine – for example, vegans or those avoiding iodised salt. Before beginning any new supplement, it is advisable to consult a health care professional to assess your individual needs.

Key Benefits of Vitamin D3 and Iodine

Vitamin D3 contributes to the normal function of the immune system (EFSA approved claim). It also plays a role in the normal absorption and utilisation of calcium and phosphorus, helping to maintain normal bones and teeth. Iodine contributes to normal thyroid function and normal cognitive function, as well as normal energy-yielding metabolism. These nutrients work together to support overall wellbeing.*

What Makes This Supplement Special?

Unlike standard vitamin D products, this formulation pairs 5000 IU (125 mcg) of vitamin D3 (cholecalciferol) with iodine derived from sea-vegetables. The D3 form is identical to that produced by the skin in response to sunlight and is known for superior bioavailability compared to D2. Life Extension sources high-quality ingredients, and this formula is certified non-GMO and gluten-free. A Certificate of Analyse is available for each batch, guaranteeing purity and potency.

Quality and Purity You Can Trust

Life Extension is committed to scientific rigour. Manufactured in the USA under strict quality control, this product is non-GMO and gluten-free, making it suitable for many dietary preferences. Each batch undergoes testing to confirm label claims, and capsules contain no unnecessary additives. The easy-to-swallow design simplifies daily supplementation.

Recommended Dosage and Usage

The suggested serving is one capsule daily, ideally with a meal containing fat to enhance absorption, as vitamin D is fat-soluble. Each capsule provides 5000 IU (125 mcg) of vitamin D3 and a proprietary blend of sea-iodine. For most adults, this dose is within safe limits, but those with specific health conditions or taking medications should seek medical advice. Long-term uses is intended, whilst periodic monitoring of vitamin D levels is recommended.

Safety Considerations

Vitamin D is generally safe at recommended doses, but excessive intake may lead to hypercalcaemia. The UK Guidelines suggest a tolerable upper intake level of 4000 IU per day from all sources; this product contains 5000 IU, so it is intended for those with higher requirements or under professional supervision. Iodine from sea-vegetables is naturally occurring, but caution is advised for individuals with thyroid disorders or iodine sensitivity. Keep out of reach of children and store in a cool, dry place.
