Review: Excellent product, Use 2-3 Times a Week and Eat Properly - 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. Review: High dose D3? Get K2 also! - I take high dose vitamin D3. If you take high dose vitamin D3 you should take this with it. In a YouTube video I watched they describe K2 like being a traffic cop and directing the D3 where to go in the body. Allegedly otherwise the high dose D3 can build up and cause stiff neck or joints or something. It's cheap and living in the Midwest I need a D supplement in the cold months so I buy this with it. If you swallow pills that are oblong these won't be a problem. They aren't tiny but also aren't huge. Do I notice anything? No. Does the high dose D3 cause any issues......no. So it must be working. I do blood tests so I know the D3 is getting absorbed at least. Cheap insurance I figure. Vitamins often work together and this is often recommended with D3 supplements. ## Features - BIOLOGICALLY ACTIVE FORM*/MENAQUINONE-4: As a biologically active form of vitamin K, K-2 is important for the formation of healthy, strong bone matrix* - SUPPORTS BONE HEALTH AND PROPER CALCIUM METABOLISM*: Vitamin K's role in arterial health revolves around its ability to support proper calcium metabolism in vascular structures* - CERTIFICATIONS/CLASSIFICATIONS: Halal, Dairy Free, Egg Free, Kosher, Made in Peanut-Free Facility, Made without Gluten, Non-GMO, Nut Free, Soy free, Vegan/Vegetarian - GMP Quality Assured: A-rated, third-party certification means that every aspect of the NOW manufacturing process has been examined.

MK-7 is short-hand for menaquinone-7, a form of vitamin K-2. Every container has a prominent display of "Supplement Facts" listing the major, active ingredients. Below that will be listed "Other ingredients." Read your labels. **Q: Why vitmin k2 manufacture from herb ?** A: Have not received this K2 yet. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 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.
