Beef shank is a cut of beef that comes from the leg of the cow, and it contains a variety of essential nutrients, including vitamins and minerals.

Protein: Beef shank is a good source of high-quality protein, which is essential for muscle growth, tissue repair, and overall health.

Iron: Beef shank provides a significant amount of heme iron, which is readily absorbed by the body and important for oxygen transport in the blood. Iron is essential for preventing anemia.

Zinc: This mineral is crucial for immune function, wound healing, and DNA synthesis. Beef shank is a good source of zinc.

Phosphorus: Phosphorus is important for strong bones and teeth, and it plays a role in various cellular processes. Beef shank contains phosphorus.

B Vitamins: Beef shank contains various B vitamins, including B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), and B12 (cobalamin). These vitamins are important for metabolism, energy production, and the functioning of the nervous system.

Vitamin A: Beef shank provides vitamin A in the form of retinol, which is essential for vision, skin health, and immune function.

Vitamin D: Beef shank contains small amounts of vitamin D, which is necessary for calcium absorption and bone health.

Vitamin K: This vitamin is important for blood clotting and bone health.

Collagen: Beef shank is rich in collagen, a protein that supports the health of joints, skin, and connective tissues.

Creatine: While found in relatively small amounts in beef, creatine is important for muscle function and energy production.
