Vitamin D3 + K2
Sports Research Vitamin D3 + K2 is a high-potency dietary supplement designed to provide vitamin D3 and vitamin K2 in a single daily softgel. Each serving provides 5,000 IU of vitamin D3 alongside 100 mcg of vitamin K2 as MK-7. The formula uses vitamin D3 derived from lichen and vitamin K2 sourced from chickpeas, making it suitable for consumers looking for a plant-based alternative to conventional D3 supplements. The linked version contains 120 veggie softgels and uses coconut MCT oil as part of its oil-based formulation.
The product focuses on a simple two-nutrient formulation while incorporating several quality and dietary considerations. Sports Research lists the supplement as Vegan Certified and Non-GMO Project Verified and states that it is third-party tested and manufactured in the United States in a cGMP-compliant facility. Its plant-based softgel avoids conventional gelatin, while the combination of D3 and MK-7 K2 provides a convenient option for adults specifically looking to supplement both nutrients together. At 5,000 IU of vitamin D3 per serving, however, this is a relatively high-potency formula, so consumers should consider their existing vitamin D intake and individual nutritional requirements before regular use.
Summary
Sports Research Vitamin D3 + K2 combines 5,000 IU of plant-derived vitamin D3 with 100 mcg of vitamin K2 as MK-7 in a once-daily vegan softgel. Its straightforward formulation, plant-based ingredient sourcing, coconut MCT oil carrier, and product-specific testing and certification credentials make it a convenient option for consumers seeking a combined D3 and K2 supplement.
