I thought it was MK-7 but found out that it was MK-4. Which is fine except you need to take more of MK-4 to get the benefits. They actually also sell a product that has MK-7 written on it. As they told me on the phone, their products are MK-4 unless specifically mentioned on the label. I am happy with NOW; I have confidence in their products. **Q: Is this a capsule or pill?** A: Capsule **Q: i do not understand is why it says it alfalfa? is that literally all it is? just ground up alfalfa?? i see nothing to suggest other than alfalfa?** A: It does not just say alfalfa it says Vitamin C, Vitamin K2 (as menaquinone 4) and alfalfa powder. Alfalfa is a source of vitamins A, C, E, and K4; and minerals calcium, potassium, phosphorous, and iron. **Q: Dr recommended 1000 mcg k2, but in reviewing MK-4 and MK-7 I think I need the MK-7. Haven't found it in 1000 mcg. Can you help? The NOW bottle that comes up on Amazon is not 1000, it is 100 mcg.** A: Just finished reading about vitamin K and all the different types from 'Vitamin K2 and the Calcium Paradox'. Excellent book I must say. Your doctor must have been refering to MK-4 version of Vitamin K2 which has a half life of 1 hour i.e. you have 1/2 of amoun ingested after 1 hour, so you definitely need a lot. The MK-7 version of vitamin K2 has a much longer half life and hence you don't need as much. Today's medicare and doctors are extremely ignorant unfortunately. ## Customer Reviews ### ⭐⭐⭐⭐⭐ مطابق للمواصفات المطلوبة *by S***D on 11 November 2025* عالي الجودة ### ⭐⭐⭐⭐⭐ جيد *by S***H on 30 March 2024* جيد ### ⭐⭐⭐⭐⭐ very good product *by J***S on 10 August 2023* very good product ## Frequently Bought Together - NOW Foods Supplements, Vitamin K-2 100 mcg, Menaquinone-4 (MK-4), Supports Bone Health*, 100 Veg Capsules - NOW Foods Supplements, Vitamin D-3 5,000 IU, High Potency, Structural Support*, 240 Softgels - NOW Supplements, Vitamin A 10,000 IU, Eye Health*, Essential Nutrition, 100 Softgels --- ## 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.us/products/253330094-supplements-vitamin-k-2-100-mcg-menaquinone-4-mk-4](https://www.desertcart.us/products/253330094-supplements-vitamin-k-2-100-mcg-menaquinone-4-mk-4) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-22*
