Frequently Asked Questions

What are the benefits of bone marrow supplements?

Bone marrow supplements provide alkylglycerols (immune-modulating lipids), fat-soluble vitamins A, D, E, and K2, collagen, and growth factors. They are primarily used for immune support, joint health, and as a whole-food source of nutrients that are difficult to obtain from modern diets. The evidence is emerging but grounded in strong ancestral nutrition principles.

Is bone marrow supplement the same as bone broth?

No. Bone broth is made by simmering bones in water, extracting primarily collagen, gelatin, and minerals. Bone marrow supplements are freeze-dried from the marrow tissue inside bones, preserving alkylglycerols, fat-soluble vitamins, and growth factors that are largely absent from bone broth. Marrow provides a different and more concentrated nutrient profile.

Should bone marrow supplements be grass-fed?

Yes. Grass-fed bone marrow has a superior fatty acid profile, including higher levels of omega-3 fatty acids, conjugated linoleic acid (CLA), and fat-soluble vitamins compared to grain-fed sources. Look for supplements from grass-fed, pasture-raised cattle from New Zealand or Australia, where grass-feeding practices are standard year-round.
