Review: Life Extension Vitamin D3+K2+iodine improved my vit D deficiency! - My doctor ran some standard blood tests back in January 2026 and told me my vitamin D levels were low. The blood tests confirmed what I had suspected because I felt like I had no energy, my sleep schedule was awful, my mood was off and I was suffering from migraines on a monthly basis(due to hormonal changes). I’ve done my research and homework on vitamins and supplements and I know for Vitamin D to be effective it should be paired with Vitamin K2 for maximum absorption. I found the Life Extension brand because it checked both boxes(vit D3 and K2). The addition of iodine was also a big plus for me because I had been considering adding an iodine supplement to my daily vitamin regimen. I love that the iodine is sourced from seaweed and not made in some lab. The capsules are small and easy to swallow. Every other vitamin D3 supplement I’ve taken in the past seems like it’s either a huge tablet or you have to take 3 capsules 3x/day. This brand is one small capsule, once a day. IMO the value for your money is excellent and worth every penny. I will continue to purchase the Life Extension brand vit D3 with K2 & iodine and have since recommended it to family and friends. All of this being said, my doctor retested my vitamin D levels a few weeks ago and I am happy to share that my levels went from 23 to 35!! My bloodwork is a confirmation that the Life Extension vitamin D3 has helped me improve vitamin D levels! 🙌🏼 💪🏼 Review: Beneficial - Tiny powder capsules. Easy to swallow. No negative side effects. Great value. ## 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. - Quality ingredients – The majority of our products are non-GMO, gluten-free and manufactured in the USA with internationally sourced ingredients. - Science matters – Expert formulators design our supplement formulas, and a Certificate of Analysis is available for every Life Extension product. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076DBV1MG | | Age Range Description | Adults | | Allergen Information | Gluten Free | | Best Sellers Rank | #3,478 in Health & Household ( See Top 100 in Health & Household ) #20 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 4,742 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 Highlight | With Vitamin D3, Vitamin K1 & K2 & Iodine, Supports Immune, Bone, Arterial & Thyroid Health, Non-GMO & Gluten-Free | | Item Weight | 1.6 ounces | | 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 | Brain Health Support, Helps counteract possible iodine deficiency in healthy diets, Helps inhibit calcium buildup in the arteries, Promotes bone, immune & cardiovascular health Product Benefits Brain Health Support, Helps counteract possible iodine deficiency in healthy diets, Helps inhibit calcium buildup in the arteries, Promotes bone, immune & cardiovascular health 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 Count | ## Product Details - **Brand:** Life Extension - **Diet Type:** Gluten Free - **Flavor:** Unflavored - **Item Form:** Capsule - **Primary Supplement Type:** Iodine, Vitamin D3, Vitamin K ## Images ![Life Extension Vitamins D and K with Sea-Iodine for Thyroid, 60 Capsules - Image 1](https://m.media-amazon.com/images/I/71c9FPmUbCL.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. If you have any additional question regarding our products please feel free to call our Wellness Specialists toll-free at 1-800-226-2370. 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 ### ⭐⭐⭐⭐⭐ Life Extension Vitamin D3+K2+iodine improved my vit D deficiency! *by L***T on May 19, 2026* My doctor ran some standard blood tests back in January 2026 and told me my vitamin D levels were low.
