Is there a smarter way to take your supplements?

According to some research, there could be one strategy for maximizing benefits. A review published in the International Journal of Endocrinology highlights a synergistic interplay between Vitamins D and K for both bone and cardiovascular health.

“Vitamins D and K are both fat-soluble vitamins and play a central role in calcium metabolism,” the review explained. “Vitamin D promotes the production of vitamin K-dependent proteins, which require vitamin K for carboxylation in order to function properly.”

In short, Vitamin D3 helps your body absorb calcium, while K2 helps guide it into the bones. And some specialized formulas offer both vitamins packed in one simple capsule to support absorption.

Sports Research D3 + K2 is among them — a plant-based formula designed to support bone strength, immune function, cardiovascular health and healthy calcium metabolism by combining clinical dosages of Vitamins D3 and K2. The supplement retails for $23, with an additional 15% off when you subscribe.

The popular formula is backed by thousands of positive reviews, with many customers claiming the benefits stretch beyond your typical single-vitamin supplement.

“I got this supplement about a month ago,” one user shared.

“My bone density has gotten worse with age. I was told to take vitamin D to help my bones. I feel like my disposition has gotten better; my bones don’t ache as much. It also has vitamin K, which helps with your immune system. To me, it’s a win-win situation,” they explained.

Each daily softgel provides 125 mcg (5000 IU) vegan Vitamin D3 from lichen and 100 mcg Vitamin K2 (MK-7) from fermented chickpeas, with coconut MCT oil added to support absorption. Sports Research is also third-party tested, non-GMO project verified and NSF gluten-free certified.

The product is a No. 1 selling D3 + K2 brand, based on combined U.S. retail data from Amazon and internal U.S. club channel sales collected last year.
