So if you are one of these prospective shoppers, keep in mind that a K2 Vitamin supplement may be able to help you support healthy bone metabolism and your body's ability to use calcium efficiently. This is because K2 vitamins can help activate the calcium-binding properties of proteins, which then helps calcium travel to different tissues around the body. In this way, the k-2 vitamin can also help support healthy joints and tissues. So if you are curious to see whether vitamin k 2 can work within your curreent supplement routine, consider asking your doctor today if this Ultra K 2 Vitamin supplement could be a helpful option for you. If you are already looking for a vitamin complex or multivitamin with k2, you may find that this k vitamin supplement gives you an ultra efficient way to get the vitamins K2 you want to add to your existing diet.* Review: Great price for an actually therapeutic dose - Good value for therapeutic dose.

Thank you😊** A: I would like to know this answer to, whether it’s synthetic or natural source. But my big question is why people feel the need to answer a question; sorry to say, stupidly. “I don’t have it anymore” okay, so why do you feel the need to answer this question then? I see sooo many countless, meaningless answers over many products. Do these folks really have so much time on their hands?!? Unless you have something meaningful to contribute what’s your need to answer? This is the same with social media- we don’t care. **Q: How much silicon dioxide is in 1 pill?** A: The amount is not listed **Q: What is the source this is made from?** A: The bottle indicates 90 vegetarian capsules, with a somewhat long list of stuff it does not contain like non-vegetarian ingredients, tree nut, peanuts, wheat, gluten, soybeans, corn, yeastand artificial colors, flavors or preservatives. Apart from that, no word about what it is made from. Sorry. **Q: are the capsules suppose to be yellow?** A: I never took K2Mk4. K215mg or 15.000mcg is white ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great price for an actually therapeutic dose *by J***C on June 12, 2025* Good value for therapeutic dose. ### ⭐⭐⭐⭐⭐ Expensive but seems to work. *by T***0 on December 13, 2025* Seems to work clearing out the arteries but expensive. ### ⭐⭐⭐⭐⭐ high potency K2 MK4 is a good velue *by A***E on July 19, 2023* this K2 MK4 product is a good way to keep blood pressure under control (see pubmed) most other K2 formulations are only in the microgram doses and have a corresponding lower benefit. ## Frequently Bought Together - Klaire Labs Ultra K2 Menaquinone - 4 - Vitamin K2 Supplement with 15mg of Vitamin K2 MK4 per Capsule - Support Bone & Cardiovascular Health - Hypoallergenic & Vegan Vitamin K (90 Capsules) - Pure Encapsulations Vitamin D3 125 mcg (5,000 IU) - Supplement to Support Bone, Joint, Breast, Heart, Colon, and Immune Health* - with Vitamin D - 120 Capsules - Pure Encapsulations Magnesium (Glycinate) - Supplement to Support Stress Relief, Sleep, Heart Health, Nerves, Muscles, and Metabolism* - with Magnesium Glycinate - 180 Capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/73898410-klaire-labs-sfi-health-ultra-k2-menaquinone-4-vitamin-k2](https://www.desertcart.vu/products/73898410-klaire-labs-sfi-health-ultra-k2-menaquinone-4-vitamin-k2) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-08*
