It seems MK-4 exists in certain mammalian tissues, with some organs having higher concentrations than others. Experiments with radio-labeled K-1 suggests that it can be converted into MK-4, but probably not at the therapeutic level individuals might seek. The source in supplements seems to be entirely synthetic for MK-4(from a tobacco product I read), because sourcing animal products for it for extraction would be out of sight expensive. The highest food source seems to be "Fois Gras" and has 369 mcg in 100 grams, etc. Geese seem to consume the type of grass and consequently K-1 that their system can convert to Mk-4. MK-9 seems exist in certain cheeses and has a very long half-life. Mk-7 might have a three day half-life it is claimed. MK-4 is said to be prescription in Japan for osteoporosis and typically given at 45 mg a day, in three 15 mg doses. Taking it with oil or fat containing meals seems to have a huge impact on absorption and consequentially utilization. I ordered two shippings of "two month supplies" at the just mentioned dosage, from a different than desertcart vendor, after ordering and partially consuming this Carlson product. I just discovered that desertcart now has vendors, including itself or Prime vendors, that carry the 15 mg/90 capsule bottles, which would be the Japanese monthly dosage for osteoporosis therapeutics. The source, brand, bottler, or whatever is called "Complementary Prescriptions" and can be located with a search on desertcart. The bulk manufacturer is probably based in China, though this isn't documented for the above product, there does seem to be MK-4 manufacturing sources in China, (...and since it isn't stated as being based elsewhere...). edit: In Japan the supplier is "Eisai" who apparently has a patent from the Ministry of Japan. MK-4 is sold in Japan and across Asia under the brand name Glakay. Review: Vitamin K2 plays a key role in the proper distribution of calcium; in particular, it helps to move it out of the circulatory system where it can lead to atherosclerosis and into the skeletal system leading to stronger bones. It is hard to get enough K2 from diet alone and while the body converts some vitamin K1 into K2 the conversion rate decreases with age. Vitamin K2 supplements typically come in one of two forms: MK4 or MK7. Both forms have shown some success in the treatment of osteoporosis. MK4 has a short half-life in the blood of only a few hours whereas MK7 has a much longer half life. In Japan, MK4 is used, by prescription, to treat osteoporosis at a dose of 45 mg/day typically subdivided into three smaller doses whereas MK7 is typically taken is much smaller doses of ~100 micrograms/day. The Carlson capsules contain 5 mg of MK4, so one would need to take 9 per day to match the dose prescribed in Japan (Carlson Labs only recommends taking 1 capsule per day). Even one capsule provides 6250% of the RDA for vitamin K. Presumably the very high dosages were initially explored to counteract the short serum half like of K2/MK4 and research into benefits at lower doses is not yet available. Vitamin K is typically well tolerated at very high doses (K1 does not seem to have an established dose at which it becomes toxic) so for many people greatly exceeding the RDA values won't be an issue. However, Vitamin K interferes with blood thinning medications such as Warfarin, so doses at these levels are dangerous for those taking these medications. Partly for this reason, you don't typically find vitamin K2 in multivitamins. A very strong case can be made for the benefits of supplementation of K2, but optimal dosing and the choice between MK4 and MK7 are murky issues at this time. Supplementing with both MK4 and MK7 may be the best option. ## Features - We carry a wide range of basic vitamins and supplements. 1 - Our store has our own maximum order price to avoid the trouble of customs incident.

It helped me with my gut. I was low on D myself but not now. My understanding of calcium is you must have adequate D. Also of course adequate C for gums. **Q: How large are the capsules?** A: very small, there is large, medium, regular and this capsule is smaller than all of them and easy to swallow. **Q: is this dry or oil inside the caps?** A: This product is the dry capsules **Q: Where do the raw materials come from? Do any come from China? Please elaborate.** A: All K-4 is sourced from CHINA. The vitamin is just assembled in the US for ingredients sourced around the world. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***K on June 10, 2013* I purchased this product here and was happy with it.

I joined a group on facebook that's for Vitamin D users. I learned there that D is processed best with certain other nutrients in good supply, such as fats, and K2. I was taking that protocol for awhile and someone mentioned that certain types of K2 can cause anxiety-like symptoms such as sweaty palms, jitters, pounding heart. I realized I'd been having those issues, so I got this K2 which they said had a low-risk version of the nutrient. Sure enough, I felt lots better after switching. No more side effects. Now this is my K2. ## Frequently Bought Together - Carlson - Vitamin K2, MK-4 (Menatetrenone), Vitamin K Supplement, Bone & Heart Health, K2 Vitamin, Soy-free, Vitamin K-2, K2 Vitamins, 180 Capsules - NutriZing K2 Vitamin Supplement MK-7 - High Strength 600mcg - Supports Bone & Arterial Health - 90 Vegan Capsules - Vitamin K2 for Men & Women - 3 Month Supply - Life Extension Super K, vitamin K1, vitamin K2 mk-7, vitamin K2 mk-4, vitamin C, bone/heart/arterial health, 3-month supply, Gluten-Free, 1 Daily, Non-GMO, 90 softgels --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/730779996-carlson-labs-vitamin-k2-menatetrenone-5-mg-180-capsules](https://www.desertcart.vu/products/730779996-carlson-labs-vitamin-k2-menatetrenone-5-mg-180-capsules) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-07*
