Synergystic Support with Vitamins D3 + K2

Vitamins D3 and K2 help your body absorb calcium and guide it to bones, while helping support proper calcium distribution away from soft tissues like arteries.

Nutrients for Additional Support

Vitamin C supports the body’s collagen production, while L-Lysine plays a key role in forming collagen—an essential protein that makes up the structural matrix of bones, joints, skin, and internal organs. Boron helps support calcium metabolism, and Inulin promotes gut health, which can aid in calcium absorption. Together, these nutrients offer well-rounded support for bone strength, connective tissue health, immune function, and overall vitality.

Reviews

High Quality Calcium

"Taking Just Ingredients Calcium Complex gives me peace of mind knowing it’s going to help me reach my health goals. I can count on it being a high quality, dairy free, way of getting the calcium my body needs."

Tami C. (5/5)

Taking for bone regrowth

"My son had a growth plate issue that required two surgeries and having to be on crutches for months waiting for bone to heal and show regrowth. I started him on this because it was the best combination of vitamins and minerals for calcium I could find. At his 6 week follow up, it is showing good bone regrowth so we will continue on this for sure. He hasn’t experienced any side effects or issues with taking 2/day."

Q&A

Are these vitamins cold processed?
For a mineral supplement like our Calcium Complex, heat doesn't affect the integrity of the ingredients the same way. Minerals are naturally stable, so cold processing isn't really a meaningful factor for this type of product.
Is it vegan or vegetarian suitable?
Yes! Our Calcium Complex is completely vegan and dairy-free. All of the ingredients are plant- and mineral-based, and the Vitamin D3 we use comes from a vegan source (VegD3®). There are no dairy-derived ingredients included in the formula.
Is this safe during pregnancy?
For pregnancy and breastfeeding, we always recommend consulting with your doctor to determine what is best for your individual needs. Many of our ingredients are commonly found in prenatal vitamins or are made from real food sources, but your doctor can provide guidance specific to your health.
Is this product third party tested?
Great question! All of our products are 3rd party tested! You can find the COA results available on our website!
Is the d and K in this similar to what is in your d and K sulpplement , if you are taking this Do you need to take D and K supplement as well . The less pills I have to swallow the better for me !! But I want to make sure I’m getting the amount I need !
Thank you for reaching out! Our Calcium Complex: Vitamin D3: 50 µg (micrograms) Daily Value: 250% Vitamin D3 + K2: Vitamin D3: 125 µg Daily Value: 625% They are not the same. The Vitamin D3 + K2 supplement has more than double the amount of Vitamin D3 compared to the Calcium Complex.
