The standout feature is its use of 100mcg of menaquinone-7 (MK-7), the most bioavailable form of vitamin K2. Sourced from fermented chickpeas rather than soy, it remains active in the bloodstream longer than MK-4 or vitamin K1, making it more effective for bone and cardiovascular support.

Buying Guide: How to Choose the Right Sports Research Vitamin K2 MK7 Supplement
1. Form of Vitamin K2: MK-7 vs MK-4
Sports Research exclusively uses MK-7 (menaquinone-7), which is the most bioavailable and long-lasting form of vitamin K2. Unlike MK-4, which stays in the bloodstream only a few hours, MK-7 remains active throughout the day. This means you need only one small softgel per day to maintain steady levels.
When choosing a K2 supplement, always look for MK-7 on the label. Sports Research delivers 100 mcg of pure MK-7 in each serving, making it an excellent choice for daily bone and cardiovascular support.
2. Source and Purity: Fermented Chickpeas and Vegan Certification
Many vitamin K2 supplements are derived from soy, which can be problematic for those with sensitivities or who prefer non-GMO ingredients. Sports Research sources its K2 from fermented chickpeas, ensuring a plant-based, allergen-friendly product. Their K2 softgels are Vegan Certified, Non-GMO Project Verified, and free from carrageenan, gluten, and soy.
This commitment to clean ingredients means you get a pure supplement without unwanted fillers. Each batch is third-party verified for quality and manufactured in a cGMP-compliant facility in the USA.
3. Absorption and Bioavailability: The Role of Coconut MCT Oil
Vitamin K2 is fat-soluble, so it needs to be taken with dietary fat for optimal absorption. Sports Research adds coconut MCT oil to their softgels, providing a built-in source of healthy fats. This ensures your body can fully utilize the MK-7 without needing to plan your supplement around meals.

4. Combination with Vitamin D3: Synergistic Benefits
Vitamin D3 helps your body absorb calcium from food, while vitamin K2 directs that calcium to your bones. Taking them together creates a powerful team for bone density and arterial health. Sports Research offers a combined D3 + K2 supplement with 5000 IU of vegan D3 and 100 mcg of MK-7 per softgel.
If you prioritize a single all-in-one formula, this combo may be ideal. For those who prefer separate supplements, the standalone K2 products are equally high quality. Learn more about nutrient synergy in our 5 Essential Nutrients for Healthy Circulation article.
