If you’re someone who regularly stays on top of your health and fitness, you know how important vitamins D3 and K2 are. Both vitamins work symbiotically to improve bone health, vascular integrity and immune support.
Don’t just take my word for it, experts agree on the benefits of taking both vitamins together. According to a 2025 study, researchers conducted a double-blind trial in 142 postmenopausal women with osteopenia, a bone disease that leads to decreased bone density. Randomly, one group took either vitamin K2 or a placebo for 3 years. Both groups also took vitamin D3 and calcium.
The study found that the group that received vitamin D3 and calcium supplemented with vitamin K2 had increased levels of activated osteocalcin, a bone-building protein, compared to the placebo group that received only vitamin D3 and calcium.
Transparent Labs is a supplement company that takes its name seriously. All products undergo third-party testing, ensuring high quality control and the effectiveness of each supplement.
Delivered in vegetarian softgel tablets, get 60 servings of these vitamins D3 and K2. In addition to improving your bone health, taking them is a good way to improve your overall well-being by helping your body reach optimal condition. Made with clean, vegan ingredients, all dosages are clinically validated for the best results.
Reviewers say they noticed a difference with these tablets, reporting that they are “easy to swallow” and have no stomach problems if taken without food or drink.
“I’m an older woman living in the subarctic and these two things conspired to give me low vitamin D levels. But even with the prescribed 5,000 units, I wasn’t reaching optimal levels. Turns out K2 is the key! Now my levels are exactly where they should be,” one reviewer shared.
Another reviewer said: “I’ve been taking supplements since I started fitness in my early 20s. I’m now in my 40s. During my fitness journey, I’ve tried many supplement brands, but none have been as effective as Transparent Labs. This brand is top notch. Their supplements are high quality.”
