Choline + Cobalt + Cyanocobalamin + Iron + Vitamin B1 is a combination of different vitamins and minerals.

• Choline: Choline is a nutrient that functions similarly to the B vitamins. Choline is involved in a variety of biochemical pathways in the human body. It's crucial for the nervous system's development and normal brain function.
• Cobalt: Cobalt is a trace mineral. It is a component of vitamin B12 and is consequently required for cellular function. It also plays a role in the creation of red blood cells as well as antibacterial and antiviral substances that keep infections at bay.
• Cyanocobalamin:  Cyanocobalamin is the synthetic form of vitamin B12, which is metabolized by the body into the active form. Vitamin B12 is required for the proper function and development of almost all the organ systems, including the brain, nerves, and blood cells. Methyl cobalamin is the active form of vitamin B12. 
• Iron:  Iron is an essential mineral for the body's development and growth. Hemoglobin, a protein found in red blood cells that transports oxygen from the lungs to all areas of the body, and myoglobin, a protein that transports oxygen to muscles, are both made from iron. Iron is also required by our bodies to produce some hormones and some essential enzymes that carry out important biochemical activities.
• Vitamin B1: Thiamine Mononitrate is a preparation of vitamin B1. Vitamin B1 allows the body to utilize carbohydrates for energy. It is required for glucose metabolism and is important for nerve, muscle, and cardiac function.
