Skin, Hair & Nails

Skin, Hair & Nails is packed with vital nutrients and peptides to support healthy (and beautiful) skin, hair, and nails. Grass-fed & finished cartilage, liver, and bone marrow stimulate collagen production and reduce inflammation.

Organ Nutrients

Cartilage is rich in collagen protein to promote joint integrity, skin elasticity, and nail strength. Collagen contains hyaluronic acid that controls tissue hydration, mediates repair processes, and protects and lubricates soft tissues. Also in cartilage are proteoglycans, which are helpful for wound healing and stimulating the hair follicle growth cycle as well as maintaining optimal skin homeostasis with aging.

Liver is the single most nutritious natural food on the planet, both in terms of density and variety. It is incredibly rich in vitamins, minerals, peptides and enzymes to support immune, reproductive, digestive, musculoskeletal, and nervous health.

Bone marrow is vital for immune function and wound healing. The fat tissue in bone marrow contains adiponectin, a hormone that supports insulin sensitivity, reduces the risk of conditions such as diabetes and obesity-related cancers, and promotes metabolic and cardiovascular health. Additionally, bone marrow provides the compound glucosamine, which plays an important role in supporting cartilage, joints, and skin. Last but not least, it is a rich source of fatty acids to aid in boosting energy and mood as well as building bones.
