Support lung, respiratory, and arteriovascular health with Ancestral Supplements Grass Fed Beef Lung. Traditional peoples, Native Americans and early ancestral healers, knew that eating the organs from a healthy animal would strengthen and support the health of the corresponding organ of the individual. For instance, the traditional way of treating a person with a weak heart was to feed the person the heart of a healthy animal. Similarly, eating the lungs of a healthy animal was believed to support lung and respiratory health. Grounded in these ancient practices, Ancestral Supplements grass fed beef lung and grass fed beef liver capsules contain lung and liver, which provide arteriovascular and lung-specific building blocks, peptides and enzymes, as well as molecular biodirectors (DNA blueprints for healthy tissue) to support lung conditions as well as to support arteriovascular health. The additional beef liver in this supplement further supports the respiratory system, as well as promoting whole-body wellness. Made only from non-GMO grass fed and grass-finished cows, pasture-raised in New Zealand without added hormones, Ancestral Supplements' organ capsules contain absolutely no fillers or flow agents, just bovine lung and liver.
