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: Best Vitamin D with K for a Reasonable Price- Reordered 5 Times Already - Life Extension Certainly did Not let Us down with this Vitamin D with K Supplement. Excellent Quality with no bad smell or taste. BUT It is quite a Large Solid Oval Pill (in case Swallowing is an issue for the intended User.) It has become a staple in Our Family Supplement regimen!

## Features

- STRONG BONES, HEALTHY HEART – This formula provides a potent 125 mcg of vitamin D3 which helps promote healthy cognitive function. Vitamin D, along with vitamin K, helps get calcium into your bone matrix to maintain strong, healthy bones and teeth. Vitamin D also plays a critical role in healthy immune function and vitamin K helps inhibit calcium buildup in your arteries.
- CHANCES ARE YOU’RE NOT GETTING ENOUGH VITAMIN K – You can get vitamin K1 and K2 from your diet, but most people don’t get enough K-rich foods, such as leafy greens, cheese, or eggs daily. This formula provides a potent dose, 2100 mcg of Vitamin K1 and two forms of vitamin K2.
- HEALTH BENEFITS OF TABLE SALT, WITHOUT THE SODIUM – Iodine is essential to thyroid health. So much so, it has been added to table salt for almost 100 years. But many people avoid salt for health reasons, which can lead to inadequate iodine intake from your diet. Our formula delivers iodine from sea vegetables.
- INGREDIENTS MATTER -Sourced using only the finest raw ingredients with the purityand potency your body deserves. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every product we produce.

We believe the answers to a healthier, richer life are within reach, and that rigorous scientific research is the path to get us there. Our formulations are created using the ingredients and dosages used in the studies that inspired them, ensuring that maximum bioavailability and efficacy is achieved.

## 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.
