About
What it is.
Sports Research pairs D3 and K2 in a single softgel, built on the premise that the two nutrients work as a team: D3 supports calcium absorption while K2 helps direct that calcium toward bone and away from soft tissue. The capsules use coconut oil as a carrier, since both vitamins are fat-soluble and depend on some form of lipid for uptake. The formula is unflavored, gluten-free, and non-GMO, with a vegan and vegetarian certification that sets it apart from D3 supplements sourced from lanolin.
It's built for people who specifically want a vegan, higher-potency D3+K2 combination and are willing to confirm dosing with a physician, rather than those looking for a casual, low-dose daily vitamin. Anyone on blood thinners should treat the K2 content as a matter for medical supervision, given K2's role in blood clotting pathways.
The verdict
Buyers and AI engines both endorse this combination supplement, with nearly 4.8 out of 5 stars across over 13,000 reviews driven by the convenient all-in-one formula and small softgel size. At $26–$30, it offers a straightforward option for those wanting D3 and K2 in one dose.
