Life Extension Vitamins D and K with Sea-Iodine – 60 capsules

★★★★★— Anonym

(5★) The best ingredients on the market because it contains both D and K. A good number of capsules (size), and the quality is good.

★★★★— Anonym

(4★) This vitamin D comes in a dry form, although the ingredient is normally made as oil capsules. I’m unsure whether the form affects the quality. In any case, this is a good blend and dosage for the immune system.

Description

Product Overview

Life Extension Vitamins D And K With Sea-Iodine is a carefully formulated dietary supplement in capsule form, combining three important nutrients in one convenient dose. Each bottle contains 60 capsules, providing a two-month supply when taken daily. Life Extension is an American brand with extensive experience in science-based supplements, known for its rigorous quality control and use of carefully selected ingredients.

What sets this product apart is its combination of vitamin D3 and several biologically active forms of vitamin K, together with a natural iodine complex derived from sea algae. This makes it easier to meet several important nutritional needs with a single capsule, which can help simplify an effective daily supplement routine.

Active Ingredients & Science

The active form of vitamin D in this product is D3 (cholecalciferol), the form the body produces itself in response to sun exposure and one with high bioavailability. Vitamin K is included in an advanced blend of K1 (phylloquinone) and K2 in the forms menaquinone-4 (MK-4) and trans-menaquinone-7 (MK-7). The iodine comes from Sea-Iodine, a natural sea-salt complex that provides a pure, well-balanced source of this mineral, which is important for thyroid function.

Benefits & Uses

  • Easy way to take three important nutrients: Ideal if you want to get vitamin D, K and iodine without having to take several different supplements.
  • Everyday support when sunlight is limited: This capsule may help maintain vitamin D levels, particularly during autumn and winter.
  • Convenient for those seeking high quality: Combines well-studied, bioavailable forms of vitamin K with iodine from natural sources.
  • A good choice for those seeking a gluten-free, non-GMO-certified supplement: Formulated to suit a wide range of diets and lifestyles.

Use & Dosage

The recommended dose is one capsule daily, providing 125 mcg of vitamin D3, 2,100 mcg of vitamin K in various forms, and 1,000 mcg of iodine. For best absorption, take the capsules with a meal, particularly as vitamins D and K are fat-soluble. The product can be combined with other supplements containing calcium or magnesium, but it is important to follow the recommended dosage and not exceed it. The convenient capsule size makes it easy to incorporate into your daily routine.

Quality & Manufacturing

Life Extension manufactures its supplements in the USA to high quality standards, with strict controls on raw materials and finished products. The products are gluten-free and non-GMO-certified, meaning no genetically modified ingredients are used. Manufacturing follows GMP (Good Manufacturing Practice) to ensure purity and safety.
