Your Body Absorbs Calcium Just Fine. That's Only Half the Battle.

Here's what most people never hear: Vitamin D3 is excellent at one job, helping your body pull in more calcium. But absorbed calcium is only useful if it ends up in the right place. Without the proper signal, it can settle where you don't want it instead of going to your bones and teeth. That's the gap in almost every vitamin D routine, and it's exactly the gap this 2-in-1 formula was built to close.

Why Vitamin D3 + K2 + BioPerine?

Most D3 supplements stop at absorption. Ours goes further. Vitamin D3 (5,000 IU) helps your body absorb calcium, Vitamin K2 MK-7 (100 mcg), the premium, longer-acting form, helps direct that calcium to your bones and teeth where it belongs, and BioPerine® (black pepper extract) enhances the bioavailability of both. D3 opens the door. K2 shows the calcium where to go. BioPerine makes sure your body actually uses it, so more of what you take actually works.

Bone & Calcium Support

Each serving delivers 5,000 IU of Vitamin D3 (Cholecalciferol) to support calcium absorption, plus 100 mcg of Vitamin K2 MK-7 (as Menaquinone) to help guide that calcium to the bones and teeth, not the places you don't want it. Together with 210 mg of Calcium, this 2-in-1 formula is built to support strong, healthy bones and proper calcium metabolism. It's the complete system in one simple daily routine, instead of two separate bottles you have to buy and hope add up.

Immune, Heart & Daily Wellness Support

Vitamin D3 is one of the most researched nutrients for immune function and overall well-being, and the D3 + K2 pairing is valued for cardiovascular and bone support alike. At 625% DV of Vitamin D3, our formula delivers the kind of meaningful daily support most people are actually looking for, not the token sprinkle hiding in a lot of multivitamins and gummies.

Enhanced Absorption with BioPerine

An uncomfortable truth about supplements: it doesn't matter what's on the label if your body can't use it. That's why we added BioPerine® (Black Pepper Fruit Extract, 5 mg), a clinically studied absorption enhancer, to help your body make the most of every capsule. It's the difference between a supplement that just sits in your system and one that actually gets absorbed and goes to work. Most D3 + K2 products leave this out. We didn't.

Common Questions, Answered Up Front

"Is 5,000 IU a lot?" It's a common, widely-used daily amount, but as with any supplement, it's smart to confirm what's right for you with your healthcare provider, especially if you already take vitamin D.

"I take a blood thinner. Can I take this?" Because vitamin K2 plays a role in the body's normal clotting process, please talk to your doctor before taking this if you're on blood-thinning medication.

Directions

As a dietary supplement, take one (1) veggie capsule twice a day. For best results, take 20 to 30 minutes before a meal with an 8 oz glass of water, or as directed by your healthcare professional. Give your bones the full system, not half of it.

Q&A

Your vitamin D3+K2 says to take 1 capsule a day, but your recommendation says 2 capsules per day. Will taking 1 capsule give the full dosage of ingredients or does it take 2 to get 125mcg of D3 and 100mcg of K2. . That is very confusing. Not sure what I would really be getting. And if taking 2, it sounds like too much of the ingredients. Help clarify please.
Hi Donna, Thank you for your question, and we apologize for the confusion! You're correct, the serving size is for one capsule. The directions are to take one capsule twice daily. You can do this at the same time or at separate times in the day. The serving for two capsules is a common serving size and very safe/beneficial for consumption. We hope this helps! Please do not hesitate to reach out if we can be of any further assistance! Sincerely, Jordan Conner | MFL Customer Support Team
What is the source of the D3 and K2?
Hi Cliff, This is Jordan Conner with MFL Customer Support. Thank you for your question and we apologize for our delayed response. The Vitamin D3 in our supplement is sourced from cholecalciferol, which is typically derived from lanolin (a natural substance obtained from sheep’s wool). This form of vitamin D3 is highly bioavailable and effectively supports the body’s calcium absorption. The Vitamin K2 is provided as MK-7 (menaquinone-7), which is a bioactive form of vitamin K2. MK-7 is commonly derived from fermented soybeans (natto) and is known for its longer half-life in the body, making it a highly effective form of vitamin K2 for supporting bone and cardiovascular health. If you have any further questions or need more information, feel free to reach out! Sincerely, Jordan Conner | MFL Customer Support Team
