Vitamin B1 (thiamine) helps the body convert food into energy, supports nerve function, and is essential for the functioning of the heart, muscles, and nervous system. Vitamin B2 (riboflavin) is important for energy production, cell growth, and the maintenance of healthy skin and eyes. It also acts as an antioxidant, helping to protect cells from damage. Vitamin B6 (pyridoxine) is involved in over 100 enzyme reactions in the body, including those that help with metabolism, immune function, and brain development. It also plays a role in the production of neurotransmitters like serotonin and norepinephrine. Vitamin B12 (cobalamin) is essential for the formation of red blood cells, DNA synthesis, and nerve function. It also helps to prevent a type of anemia called megaloblastic anemia. **

Vitamin B12 is produced by bacteria that live in the intestines of animals, including humans. However, the human body is unable to absorb B12 produced in the intestines. Instead, we must obtain vitamin B12 from animal-based foods such as meat, fish, eggs, and dairy products, or from fortified foods or supplements. Once consumed, vitamin B12 is released from proteins in the stomach and then absorbed in the small intestine for use in various bodily functions, such as red blood cell formation and nerve function. **

Vitamin D plays a crucial role in maintaining overall health by helping the body absorb calcium and phosphorus, which are essential for strong bones and teeth. It also supports the immune system, helps regulate mood, and plays a role in cell growth and function. Vitamin D deficiency can lead to weakened bones, increased risk of infections, and other health issues. **
