Healthy circulation is critical to a dog’s well-being on a cellular level. The circulatory system supports antibodies and germ-killing cells to fight the battle for good health. Toxins in the blood or poor circulation can lead to cellular death and disease. #19 Bld Klnz is a blend of herbs historically used for supporting naturally healthy blood and circulation. We strongly recommend it for animals that would benefit from support of the circulatory system, and frequently suggest pairing this formula with #24 Immune Support.
