The Active Ingredient Is: Beef Spleen (Desiccated)

Beef spleen refers to desiccated spleen tissue from grass fed cattle, delivering concentrated nutrients in a tablet form for easy intake.

This form is freeze-dried to preserve nutrient density and is sourced from New Zealand cattle, produced in a facility that emphasises traceability and allergen safety.

What Does Beef Spleen Do?

Beef spleen delivers bioavailable nutrients such as heme iron and vitamin B12 which contribute to normal immune function and red blood cell production, supporting daily energy and vitality. This interpretation lines up with EFSA-backed nutrient roles in healthy physiology.

Dr. Biesalski from the University of Hamburg noted that beef spleen contains components believed to support these essential bodily functions, reflecting the nutrient density found in organ meats.
