Healthy Bones, Teeth and Immune Support

3,000 mg / 45-Day Supply

Whole bone matrix is an excellent source of both calcium and phosphorus. Calcium is critical for maintaining healthy bones and teeth, and also plays an important role in heart, nerve and muscle health. Phosphorus is necessary for cell growth, maintenance and repair, as well as for the production of DNA and RNA (the genetic building blocks). Phosphorus also helps to balance and utilize vitamins and minerals, such as Vitamin D, iodine, magnesium and zinc.


Bone marrow is a rich source of stem cells, which develop into red and white blood cells and platelets that support oxygen transportation, immune function and blood clotting. Additionally, bone marrow is a good source of conjugated linoleic acid (CLA), a type of fat that has been associated with a reduction in body fat deposits and improved immune function.

Whole bone matrix is an excellent source of a special type of calcium and phosphorus called microcrystalline hydroxyapatite (MCHA). Phosphorus is needed for the growth, maintenance and repair of tissue and cells, as well as for the production of the genetic building blocks DNA and RNA. Phosphorus is also needed to help balance and use other vitamins and minerals, including Vitamin D, iodine, magnesium, and zinc. 

Calcium is critical for maintaining healthy bones and teeth, but it also plays an important role in blood clotting, helping muscles to contract, and regulating normal heart rhythms and nerve functions.

Bone & Marrow - Features

Why Bone & Marrow

Humans are incredibly efficient at extracting micronutrients from bovine bone and marrow. After all, it’s something our ancestors and early humans did for millions of years.

In fact, our ancestors used to crack open long bones to get to the treasured marrow, and they swallowed bone fragments while gnawing on meat. Those bone fragments served as their primary source of calcium. Bone & Marrow offers a convenient alternative, giving you a way to access all the benefits of consuming fresh grass-fed whole bone matrix, without the hassle.

Desiccated organ meat supplements are the easiest way to add highly bioavailable micronutrients back into your diet. 

Jam-packed with valuable micronutrients like calcium, phosphorus and stem cells, Bone & Marrow is the perfect natural supplement to support the mineralization of bones and teeth and to support optimal immune, heart and nerve health.

In comparison, synthetic multivitamins offer high amounts of mostly lab-grown nutrients that the body can’t absorb and flushes out via urine. 

  • Instructions

    Take four capsules per day, or up to eight capsules per day if you suffer from severe micronutrient deficiencies or have increased nutritional requirements (e.g., due to your active lifestyle). Children can take two capsules per day, depending on their weight. Consistent and long-term use produces the best results. Ask us if you need help determining the right dosage.

  • Benefits

    Bone & Marrow is a foundational supplement for any diet or health status, helping to fill nutritional gaps and improve blood, heart and nerve health, help maintain strong bones and healthy teeth, support your immune system and more.

  • Dosage Matters!

    Each serving of Bone & Marrow contains 3,000 mg of desiccated bone and marrow, including 60% of your daily calcium and 27% of your daily phosphorus needs. If you don’t consume any other sources of those essential minerals (e.g., raw dairy), we recommend increasing your serving size to six or more capsules.

  • Quality

    All of our supplements are rigorously tested for purity and heavy metals by third-party labs. Here's a copy of the test report of our latest batch. If you have questions about it, please let us know.

Bone & Marrow - Ingredients

Nutrients in Bone & Marrow (Per Serving)

Jam-packed with valuable micronutrients like calcium, phosphorus and stem cells, Bone & Marrow is the perfect natural supplement to support the mineralization of bones and teeth and to support optimal immune, heart and nerve health.

  • Minerals

    Calcium (777 mg), phosphorus (339 mg).

  • Trace Minerals

    Boron, cobalt, copper, iron, magnesium, manganese, potassium, selenium, strontium, zinc.

  • Other

    Stem cells, conjugated linoleic acid.

  • Important Note

    Many synthetic multivitamin supplements contain significantly higher concentrations of vitamins and minerals. That's because your body doesn't absorb most of those nutrients due to their poor bioavailability. However, the nutrients in freeze-dried organ meats and bones are highly absorbable, so you don't need excessive amounts. Additionally, it's virtually impossible to overdose on nutrients from real-food sources.

  • Strong Bones and Teeth

    The type of calcium found in whole bone (MCHA) promotes bone healing, remodeling, strengthening and mineral composition. Calcium and phosphorus also play an important role in tooth mineralization. In fact, 85% of the body’s phosphorus is found in bones and teeth. By consuming adequate amounts of calcium and phosphorus (in an appropriate 2:1 ratio), you can support your bone and dental health.

  • Blood Health

    Bone marrow is a rich source of stem cells that develop into red blood cells, white blood cells or platelets, which play important roles in oxygen transportation and blood clotting. By consuming bone marrow you can support your body in maintaining healthy levels of those blood cells. 

  • Immune System

    The stem cells in bone marrow play an important part in the innate and adaptive immune response. For example, some stem cells release molecules that reduce viral replication and reduce hypercytokinemia and inflammation induced by the immune system. By consuming bone marrow you can support your immune system optimally.

  • Cellular Health

    Aside from calcium, phosphorus is the most abundant mineral in the human body and is a vital factor in cellular growth, repair and maintenance. It’s also involved in the production of the genetic building blocks DNA and RNA. By consuming adequate amounts of phosphorus from animal-based sources, such as bones, you optimally support your cellular health.

  • Energy Production

    Phosphorus helps the body make adenosine triphosphate (ATP), a molecule the body uses to store energy. Producing sufficient ATP is a key requirement for maintaining optimal energy levels and athletic performance. Consuming adequate amounts of phosphorus from animal-based sources helps your body perform with peak energy.

  • Muscle Recovery

    Inadequate phosphorus levels can cause muscle weakness and muscle pain after strenuous exercise. By consuming adequate amounts of phosphorus from animal-based sources, you can help your muscles contract optimally and promote better post-workout recovery.
