Freeze-Dried Grass-Fed Beef Bone Marrow, 90 Capsules (500 MG per capsule)

Beef bone marrow contains stem cells that form platelets, white blood cells, and red blood cells. It is rich in fat-soluble vitamins A and K2,
which support the immune system and crystalline lens health (eyes).

White blood cells provide and help the body fight off diseases and infections. When the body comes into contact with pathogenic pathogens (such as viruses or bacteria), white blood cells are sent to eliminate the invaders, thereby preventing or shortening the course of illness. White blood cells also help your body fight cancer. Since cancer cells are foreign substances to the body, white blood cells such as lymphocytes can help eliminate them.

What causes a low white blood cell count?
While many conditions can cause a high white blood cell count, there are only a few main causes for a low white blood cell count, most of which are medication side effects. These causes include: chemical drugs, chemotherapy drugs, immunosuppressants, antibiotics, anticonvulsants, antihistamines, antithyroid drugs, arsenicals, barbiturates, diuretics, sulfonamides, bone marrow failure, autoimmune diseases.
