## Description

Although Vitamin K is historically known for its role in normal blood clotting function, we now know that Vitamin K is also essential to bone, cardiovascular, and nervous system health.* As a biologically active form of Vitamin K, K-2 is important for the formation of healthy, strong bone matrix.* Vitamin K's role in arterial health revolves around its ability to support proper calcium metabolism in vascular structures.* Natural color variation may occur in this product.

Review: affordable and high quality! - great vitamins although these are a bit hard for me to take because of the taste/smell but they are good nonetheless! not all vitamins are going to taste too good. i bought this along with some of their other vitamins and i notice a difference especially with my brain fog, it has been a lot more clear
Review: Vit D - I am low in vitamin D and I take a prescription. K2 helps. You absorb the vitamin D better. My last lab work was perfect so I will continue to take this daily.

## Questions & Answers

**Q: I am wondering if this is MK-4, MK-7, a mix or something else entirely?**
A: I had to call NOW to find out.  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.

great vitamins although these are a bit hard for me to take because of the taste/smell but they are good nonetheless! not all vitamins are going to taste too good. i bought this along with some of their other vitamins and i notice a difference especially with my brain fog, it has been a lot more clear

### ⭐⭐⭐⭐⭐ Vit D
*by M***O on February 22, 2026*

I am low in vitamin D and I take a prescription. K2 helps. You absorb the vitamin D better. My last lab work was perfect so I will continue to take this daily.

### ⭐⭐⭐⭐⭐ Excellent product, Use 2-3 Times a Week and Eat Properly
*by S***N on December 3, 2025*

First of all, food supplement take time to have the effect on the body that is described in the advertisement. However, the information provided was quite accurate. I am not a vitamin gobbler. I take a set of them from Liposomal , to coral calcium, fish oil, MVI, CoQ10, and others on the average of twice a week. As a research RN I do not want to replace the body functions of absorbing vitamins and minerals from the food I eat at my 80 years of youth, just give the body a slight boost in case. This way I have been able to actually keep my 3 cardiac meds to the lowest doses, stop taking statins completely, and with continued daily exercising, like 2+ mile walks a day at a good pace, treadmill walks and medium weight lifting/curls, a diet consisting of only two meals a day, and managing sugar intake with more quality snacks like mixed nuts, etc. I have had no problems with this product at the low dosage. Since I take supplements to replace "chemical" medications, I am wary of over dosing and wasting good money. The vitamin content is quite adequate, per the pharmacological literature I have read. The capsules are small, easy to swallow.
