Review: Vitamin D & K with Sea-Iodine - I’ve been using Life Extension Vitamins D and K with Sea-Iodine for a couple of months, and I’m very pleased with the results. The combination of vitamin D3, multiple forms of vitamin K, and iodine makes this supplement stand out, as it supports not only immune and bone health but also thyroid function and overall wellness. I appreciate that the capsules are small and easy to swallow, with no noticeable taste, which makes them convenient for daily use. Since starting this supplement, I’ve noticed improvements in my energy levels and a general sense of well-being, which I attribute to the balanced blend of nutrients. My vitamin D levels, which were previously low, have returned to normal, and my nails and hair also seem healthier. The inclusion of sea-iodine is a thoughtful touch, especially for those who don’t get enough iodine from their diet. Overall, this is a high-quality, non-GMO, and gluten-free product that delivers on its promise to support immune, bone, arterial, and thyroid health. Review: Great product - I’m been taking this combine with zinc and magnesium I’m in perimenopause and I feel it has helped me to better recover in my sleep .. ## Features - Supports a healthy immune response—Are you getting enough vitamin D3 We’ve combined several nutrients diets often lack, like vitamin D, which helps maintain a balanced immune system along with other benefits, from bone health to cognitive function - Helps maintain strong bones—Vitamin D is necessary for bone health because, along with vitamin K, it gets calcium into your bones. Not only that, but we include multiple types of vitamin K in this formula: vitamin K1 as well as two types of vitamin K2. - Supports thyroid health—There’s one more nutrient some people may lack: iodine. Common in table salt (and missing from many healthy diets), iodine is used to make thyroid hormones. Your thyroid helps regulate your body’s metabolism. - Ingredients matter – We use the finest raw ingredients chosen for quality and purity. The majority of our products are non-GMO, gluten-free and manufactured in the USA with globally sourced ingredients, and a Certificate of Analysis is available for each. - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076DBV1MG | | Age Range Description | Adult | | Allergen Information | Gluten Free | | Best Sellers Rank | #3,748 in Health & Household ( See Top 100 in Health & Household ) #22 in Vitamin D3 & K2 Combinations | | Brand | Life Extension | | Brand Name | Life Extension | | Color | Beige | | Container Type | Bottle | | Customer Reviews | 4.7 out of 5 stars 4,588 Reviews | | Diet Type | Gluten Free | | Dosage Form | Capsule | | Flavor | Unflavored | | Global Trade Identification Number | 00737870204060 | | Item Dimensions | 2.09 x 2.09 x 3.73 inches | | Item Form | Capsule | | Item Weight | 0.1 Pounds | | Manufacturer | Life Extension HPC | | Manufacturer Part Number | 02040 | | Material Type Free | Gluten Free, Non-GMO | | Model Name | Vitamins D and K with Sea-Iodine™ | | Model Number | 02040 | | Number of Items | 1 | | Primary Supplement Type | Iodine, Vitamin D3, Vitamin K | | Product Benefits | Helps counteract possible iodine deficiency in healthy diets, Helps inhibit calcium buildup in the arteries, Promotes bone, immune & cardiovascular health, Supports healthy cognitive function Product Benefits Helps counteract possible iodine deficiency in healthy diets, Helps inhibit calcium buildup in the arteries, Promotes bone, immune & cardiovascular health, Supports healthy cognitive function See more | | Special Ingredients | Iodine, Vitamin D3, Vitamin K | | Specific Uses For Product | Bone Health, Heart, Immune Support, Thyroid & Adrenal | | UPC | 737870204060 | | Unit Count | 60.0 Count | ## Product Details - **Brand:** Life Extension - **Diet Type:** Gluten Free - **Flavor:** Unflavored - **Item Form:** Whole Bean - **Primary Supplement Type:** Iodine, Vitamin D3, Vitamin K ## Images ![Vitamins D and K with Sea-Iodine, Vitamin D3, Vitamin K1 and K2, Iodine, Supports Immune, Bone, arterial and Thyroid Health, Non-GMO, Gluten-Free, 60 Capsules - Image 1](https://m.media-amazon.com/images/I/71c9FPmUbCL.jpg) ![Vitamins D and K with Sea-Iodine, Vitamin D3, Vitamin K1 and K2, Iodine, Supports Immune, Bone, arterial and Thyroid Health, Non-GMO, Gluten-Free, 60 Capsules - Image 2](https://m.media-amazon.com/images/I/71iGgTS2UtL.jpg) ![Vitamins D and K with Sea-Iodine, Vitamin D3, Vitamin K1 and K2, Iodine, Supports Immune, Bone, arterial and Thyroid Health, Non-GMO, Gluten-Free, 60 Capsules - Image 3](https://m.media-amazon.com/images/I/81uqKfnLW4L.jpg) ![Vitamins D and K with Sea-Iodine, Vitamin D3, Vitamin K1 and K2, Iodine, Supports Immune, Bone, arterial and Thyroid Health, Non-GMO, Gluten-Free, 60 Capsules - Image 4](https://m.media-amazon.com/images/I/714mH0c1IeL.jpg) ![Vitamins D and K with Sea-Iodine, Vitamin D3, Vitamin K1 and K2, Iodine, Supports Immune, Bone, arterial and Thyroid Health, Non-GMO, Gluten-Free, 60 Capsules - Image 5](https://m.media-amazon.com/images/I/71ocUobSB-L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is this d3 made from lanolin (from sheep), or is it the vegan d3 made from lichen?** A: The Vitamin D3 is from Lanolin.

You can reach them from 8 a.m. to 1 a.m. weekdays and 9 a.m. to 1 a.m. weekends ET. **Q: Can anyone tell me if there is gluten or wheat?** A: While this item is not labeled as "Gluten Free" (GF) by the manufacturer, I looked up each ingredient and not any of the ingredients contain gluten. I have celiac and have been on a gluten free diet for around 12 years and this food supplement does not bother me or set off my symptoms. In fact, according to my latest blood test, my vitamin D is now within normal ranges and I no longer suffer from vitamin D deficiency after taking the supplement. I hope it works for you as well. **Q: Why is k combined with D here? What are the benefits?** A: Apparently the body needs vit K in order to full absorb the vit d. If you are low in vit D, this can effect your body is so many way, super tired, memory not so great, hair, if I am out in the sun (without sunscreen) at least 10 mins a day then i dont supplement.. **Q: Why so much salt?** A: There is no salt in this product. Iodine is not salt. Rather it is a mineral added to some salt. Iodine is a very necessary mineral to prevent goiter. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Vitamin D & K with Sea-Iodine *by Z***K on April 22, 2025* I’ve been using Life Extension Vitamins D and K with Sea-Iodine for a couple of months, and I’m very pleased with the results.
