Buying Guide for Vitamin K2 MK7
Form and Bioavailability
Vitamin K2 comes in several forms: MK4 and MK7. MK7 is the preferred form because it stays active in the blood longer and requires only one daily dose. Both Doctor’s Best and Sports Research use MK7 sourced from fermented chickpeas. Doctor’s Best uses the patented MenaQ7 brand, which has been clinically studied for bone and cardiovascular support. Sports Research also uses fermented chickpeas but adds coconut MCT oil to enhance absorption, as K2 is fat-soluble.
Serving Size and Value
Doctor’s Best offers 60 veg caps per bottle, each providing 100 mcg of MK7, with a suggested use of one capsule daily. Sports Research provides 120 softgels per bottle, also 100 mcg each. Both are one-a-day. If you care about longevity per bottle, Sports Research gives a two-month supply versus one month from Doctor’s Best. However, Doctor’s Best is often more affordable upfront. For budget-conscious buyers, the Doctor’s Best option may be appealing. If you prefer a longer supply and added absorption support, Sports Research stands out. For a similar comparison of value in other supplements, see our magnesium taurate vs thorne magnesium bisglycinate article.
Quality and Purity
Both brands prioritize clean ingredients. Doctor’s Best is non-GMO, gluten free, soy free, and vegan. Sports Research goes a step further with Vegan Certified, Non-GMO Project Verified, and free of carrageenan, gluten, and soy. Sports Research also uses a UV-protecting color barrier to prevent light degradation of the K2. Doctor’s Best relies on the established quality of MenaQ7. Both are manufactured in the USA in facilities that follow strict guidelines. For more on how purity affects supplement choices, read supplements for healthy blood flow.
Additional Formulations: D3+K2 Combos
If you want to cover two bases at once, Sports Research offers a Vegan Vitamin D3 + K2 formula in both 60-count and 120-count sizes. These combine 125 mcg (5000 IU) of vegan D3 with 100 mcg of K2 MK7, plus coconut MCT oil. This is an excellent option if you also need vitamin D for immune support and calcium absorption. Doctor’s Best does not currently offer a D3+K2 combo in this lineup. If you are interested in other D3+K2 comparisons, see our sports research D3 K2 vs thorne D K2 article.
Final Thoughts
Both the Doctor’s BEST Natural Vitamin K2 MK7 Supplement and the Sports Research® Vitamin K2 (MK-7) deliver high-quality MK7 from fermented chickpeas. For a straightforward, budget-friendly K2 that is vegan and trusted, Doctor’s Best is a smart choice. If you prefer a longer supply, added MCT oil for absorption, and a stronger vegan certification, the Sports Research option wins. And if you want both D3 and K2 in one daily softgel, the Sports Research D3+K2 combos are worth considering. Whatever you choose, consistent daily intake alongside a source of fat will help you get the most from your K2 supplement.
Frequently Asked Questions
What is the difference between MK7 and MK4?
MK7 (menaquinone-7) is a longer-chain form of vitamin K2 that stays in the body longer than MK4, meaning you only need one daily dose. MK4 is shorter-lived and often requires multiple doses per day. Most studies on bone and heart health use MK7.
Can I take K2 with vitamin D3?
Yes, vitamins D3 and K2 work together synergistically. D3 helps absorb calcium, and K2 directs that calcium to your bones and teeth. Many supplements now combine them, like the Sports Research D3+K2 formula. You can also take them separately.
How long does it take to see benefits from K2 MK7?
Benefits for bone density and arterial flexibility typically become noticeable after several weeks to a few months of consistent use. Since MK7 has a long half-life, daily supplementation builds up levels over time.
Are these K2 supplements safe for vegans?
Yes, both Doctor’s Best and Sports Research source their K2 from fermented chickpeas and use vegan capsules. Sports Research also uses a plant-based softgel (Plantgel) and avoids carrageenan. Check the label to confirm your dietary requirements.
