BoneBuilder K2

Our bones form the structure of our entire body, and protect our internal organs from external damage. They also perform important cellular functions, such as blood cell formation. As we age, our bones need support to help us live healthy, active lifestyles. MD Logic Health’s BoneBuilder K2 provides the concentrated nutritional support to help maintain optimal bone health using six carefully researched ingredients selected for their specific bone-supporting properties.

Benefits of adding Bonebuilder K2 to your diet

May help support strong healthy bones

May help with Vitamin D and Calcium absorption

May be ideal for those with osteopenia, osteoarthritis, or high risk of fracture

What makes MD Logic’s Bonebuilder K2 different?

BoneBuilder K2 supports healthy bone density with bone-derived microcrystalline hydroxyapatite, a highly absorbable compound found in bovine bone that provides calcium, phosphorus, and magnesium, along with collagen.

Similar in structure to humans' calcium, this mineral is required for strong bones and regular muscle function to blood clotting, cellular health, hormone activity, and a healthy heart rate.*

If blood levels of calcium are low due to poor diet, then calcium is reabsorbed from bones and used by the human body for maintenance. Replenishing our calcium levels every day is key to maintaining healthy calcium levels in our bones.

BoneBuilder K2 formula features Vitamin K2, which ensures  proper absorption of calcium into the bones, avoiding calcification of blood vessels, Vitamin D which enhances absorption of calcium from food in the GI tract, and  Magnesium, a key bone health nutrient that is needed to convert vitamin D to its active form and is associated with higher bone mineral density.*

Vitamin K

Both forms of vitamin K2, which promotes proper distribution of calcium for bone health and cardiovascular health*


Required for several hundred enzymatic reactions in the human body and is a common nutrient deficiency associated with osteoporosis. People with higher intakes of magnesium have higher bone mineral density, which is important for reducing the risk of bone fractures.*


400 mg of calcium from microcrystalline hydroxyapatite (derived from bovine bone)

Vitamin D3

2000 IU of vitamin D3


To strengthen bones and joints*

I think these are working.

In September of ‘22 I fractured my spine, sacrum and pelvis in a bike accident. After the MRI in in the ER it was discovered I had osteopenia, I started Bone Builder soon after that. At the six month mark I had another MRI and all of the injuries had healed with very little residual pain. Eight months later I’m feeling great and have resumed 95% of the same activities I was performing prior to the accident. I turned 65 in January and I feel great, I’m sure I have another 65 years to go. Also my weak nails are now strong and I can actually grow them.

I was having trouble with low back pain and joint pain. I saw a few Orthopedic Surgeons who was constantly injecting cortisone into my joints, which had more side effects than helping with the pain! I also saw a Foot and Ankle Specialist who told me after several office visits not to return, because my blood work, MRI scan and X-Ray results came back normal and he’s not sure what to treat me for. Since I have begun taking the Bone Builder K2 supplement which I purchased from MD Logic, I have had significantly less pain in my hips and knees. I am now able to stand for longer periods of time. Also, I was having painful foot and leg cramps most of the day and night. I do not know if there is something in this product that also reduces leg cramps, but I have not had leg cramps since after the first week on the supplement. Starting to feel like my old self again is an Absolutely Amazing feelings. I've experienced no stomach upsets either! I highly recommend this product.
