What the Research Says
Bone marrow supplementation draws primarily from ancestral nutrition principles and preclinical research on its constituent compounds. Alkylglycerols, first studied by Brohult et al. (1986) in the context of immune modulation, have shown immunostimulatory properties in multiple preclinical models. A 2019 review by Denisenko et al. in Marine Drugs comprehensively examined alkylglycerol biology, confirming their role in immune cell membrane function and signaling. The fat-soluble vitamin profile of bone marrow, particularly K2 (MK-4), has independent evidence for bone and cardiovascular health from the Rotterdam Study and subsequent trials. While no large RCTs have evaluated whole bone marrow supplements specifically, the nutrient density and traditional use provide a reasonable rationale for supplementation.
