- Codeage Grass Fed Beef Spleen supplement offers 1,500 mg of grass-fed bovine spleen per serving. The bovine spleen is sourced from grass-fed, grass-finished, pasture-raised beef in Argentina. This spleen glandular supplement is also freeze-dried, non-defatted, and desiccated.
- This beef organ supplement may offer a source of vitamins and nutrients found within the spleen tissue, such as vitamin B12, selenium, and riboflavin (vitamin B2). Additionally, beef spleen meat may also contain bioavailable heme iron, a type of iron that may potentially be more readily absorbed compared to non-heme iron.*
- In addition to vitamins and iron, spleen meat may also contain proteins such as tuftsin and splenopentin. These proteins may play a role in supporting a healthy immune system through phagocytosis and the lymphocyte function.*
- This grass-fed beef spleen supplement is non-GMO, soy, dairy, and gluten-free. This bovine supplement is also hormone-free. Each Codeage Grass-Fed Beef Spleen bottle comes with 60 servings for a 2-month supply in a capsule format.
