Nutricost Vitamin K2 MK-7 100 mcg
Nutricost delivers exactly what it promises: a straightforward MK-7 softgel with no unnecessary additives and a high count per bottle. The 100 mcg dose is optimal for most daily regimens and pairs well with vitamin D3, supporting bone density and cardiovascular health.
The softgels are small and easy to swallow, making daily use painless even for those who struggle with larger pills. The formula is clean, gluten free, GMO-free, and manufactured in a certified facility, details that matter for anyone with allergies or concerns about supplement purity.
Real-world use shows it reliably relieves nighttime leg cramps and supports overall wellness, especially when taken with dietary fat for absorption. The bottle lasts eight months if used daily, making it a practical choice for long-term supplementation.
Some buyers wish for more transparency on sourcing, but the NSF, GMP, and FDA facility certifications provide reassurance. Anyone seeking a single-ingredient MK-7 without filler will find it fits the bill, but skip it if you want a blend with D3 or extra cofactors.

- Small, easy-to-swallow softgels
- Pairs well with vitamin D3 for optimal absorption

NOW Foods Supplements, MK-7 Vitamin
NOW Foods offers a soy-free, vegan MK-7 supplement that stands out for its use of MenaQ7, a bioavailable and clinically validated form of vitamin K2. The 100 mcg dose per capsule aligns with research-backed recommendations, and the formula is free from gluten, dairy, eggs, nuts, and GMOs.
Capsules are easy to swallow and do not cause digestive issues, making this a safe addition to any supplement stack. The real-world impact includes improved bone and cardiovascular health, relief from post-surgery joint pain, and better blood pressure management when paired with vitamin D3.
Blood work improvements and positive outcomes for cholesterol and muscle pain are frequently mentioned, suggesting real benefits for those monitoring these markers. Capsules require fat for absorption, but the price and quality make it accessible.
A few capsules are not oil-filled, so taking them with food or milk is necessary. The bottle contains fewer capsules than some competitors, and advanced buyers might prefer a higher count.
Skip it if you want a softgel or a formula with D3 included.

This blend aims to optimize absorption and utilization, especially for those needing more than just K2. It’s crafted in cGMP-certified facilities and is rigorously tested for purity and potency, giving confidence to buyers who value comprehensive quality control.

Sports Research delivers a vegan, non-GMO MK-7 supplement using Plantgel softgels and MenaQ7 from fermented chickpeas, with coconut MCT oil included for enhanced absorption. The 100 mcg dose is clinically validated and suits daily supplementation, especially alongside vitamin D3.
The softgels are small, tasteless, and easy to swallow, ideal for anyone avoiding animal gelatin or soy. The formula stands out for its clean ingredient profile, third-party testing, and UV-protecting color barrier to prevent degradation.
Dental health and bone density improvements are frequently reported, and softgels keep their shape even after weeks of use. The absence of fillers and allergens makes it a smart choice for those with dietary sensitivities.

See on AmazonWhat actually matters
MK-7 form and purity
MK-7 is the most bioavailable and long-lasting form of vitamin K2, supporting bone and heart health more effectively than MK-4 or K1. Always choose supplements labeled as ‘MK-7’ and check for ‘trans’ form. Avoid blends or products that don’t specify MK-7, as they may use less effective versions.
Source and manufacturing
Natural fermentation (often from natto) yields cleaner, safer MK-7 compared to synthetic production. Look for brands that use certified manufacturing practices and highlight non-GMO, gluten-free, or vegan sourcing. Poorly sourced or synthetically produced MK-7 can contain unwanted residues or lower bioactivity.
Clinical dosing
Effective MK-7 supplements deliver 100-180 mcg per serving, matching research-backed dosing for bone and heart benefits. Too low a dose won’t deliver full results, while extremely high doses offer no proven extra benefit and may waste money. Check the label for clear dosing and avoid vague blends.
Absorption enhancers
MK-7 is fat-soluble, so pairing it with oils (like MCT or olive oil) can boost absorption. Capsules or softgels with added oils are easier for your body to use than dry tablets. Avoid supplements that lack any fat carrier or come in powder form unless you’re taking them with a meal containing healthy fats.
Third-party testing and certifications
Independent lab testing ensures potency and safety, confirming the supplement matches its claims. Choose brands that openly display third-party certification or testing results. Avoid products with vague claims or no transparency about quality control.
