Buying Guide
Dosage Strength: 100 mcg vs. 300 mcg
Vitamin K2 MK-7 is available in different potencies. A 100 mcg dose is a standard maintenance level that supports bone health and daily calcium regulation. It is ideal for most adults who already get some vitamin K from diet. The extra-strength 300 mcg option is better suited for individuals with higher needs, such as those with osteoporosis risk or those looking for more robust cardiovascular support. Both strengths from NOW use the verified MenaQ7 ingredient for reliable absorption.
Bioavailability with MenaQ7
Not all MK-7 supplements are created equal. NOW uses trademarked MenaQ7, a soy-free, bioavailable form of vitamin K2 derived from chickpeas. This ensures your body can actually use the nutrient effectively. Many clinical studies on vitamin K2 have used this specific form, giving you confidence in your choice. For overall cardiovascular wellness, you might also explore other heart-support nutrients like magnesium taurate; check our cardiovascular research magnesium taurate review.
Certifications and Dietary Needs
NOW offers options that are Non-GMO, vegan, keto friendly, and made without gluten, dairy, eggs, or nuts. This makes their MK-7 supplements accessible to a wide range of dietary preferences. The 100 mcg capsules are certified vegan and vegetarian, while the extra-strength 300 mcg versions are also vegan and soy free. If you follow a strict plant-based diet, these are excellent choices. For more on how vitamin K works alongside other nutrients for circulation, see our guide on supplements for healthy blood flow.
Capsule Count and Value
The 100 mcg strength comes in both 60 and 120 vegan capsule bottles. The 120-count option offers a longer supply at a lower cost per serving, making it the better value for regular use. The extra-strength 300 mcg versions are available in 60 or 120 capsules as well. If you want the most for your money per dose, the larger bottles are the way to go. Because strength and serving size vary, compare total mcg per bottle rather than just capsule count.
Final Thoughts
After reviewing NOW’s MK-7 vitamin K2 lineup, we recommend two standout choices. For daily bone and heart support at a moderate dose, choose the NOW Supplements, MK-7 Vitamin K-2 100 mcg (60 veg caps) for its solid value and vegan certification. If you need a higher potency for extra assurance, go with the NOW Supplements, Vitamin K2 (MK-7) 300 mcg (60 veg caps) for maximum impact in fewer capsules. Both deliver the bioavailable MenaQ7 you can count on.
Frequently Asked Questions
What is the difference between MK-4 and MK-7 vitamin K2? MK-7 is a longer-chain form derived from fermented chickpeas (natto) and stays active in your bloodstream longer than MK-4. This allows for once-daily dosing and more consistent calcium regulation. NOW’s MK-7 products use the superior MenaQ7 form.
How much MK-7 should I take daily for osteoporosis prevention? Most research supports 100 to 300 mcg per day of MK-7. A 100 mcg dose is adequate for general bone maintenance, while 300 mcg may offer extra support for those with low bone density. Always consult your healthcare provider before starting any new supplement.
Can I take NOW MK-7 with vitamin D3? Yes, vitamin D3 and K2 work synergistically: D3 helps absorb calcium, and K2 directs it to bones and teeth. Many people take them together for optimal bone and cardiovascular benefits. For a combination product, see our sports research vitamin D3 K2 plant based review.
Are NOW MK-7 vitamin K2 supplements vegan? Yes, all four NOW MK-7 products are made with vegan capsules and are free from animal-derived ingredients. They are also Non-GMO and soy free, making them suitable for vegan and vegetarian lifestyles.
