A deficiency in vitamin B12 can lead to anemia, fatigue, and neurological issues. Good sources of vitamin B12 include meat, fish, dairy products, and fortified plant-based milks.

Vitamin B6 is important for protein metabolism, cognitive development, and the production of neurotransmitters. It also supports immune function and red blood cell formation. A deficiency in vitamin B6 can lead to anemia, depression, and weakened immunity. Good sources of vitamin B6 include poultry, fish, potatoes, and bananas.

Thiamin, also known as vitamin B1, is essential for energy production, carbohydrate metabolism, and nerve function. It helps convert nutrients into energy and supports the health of the nervous system. A deficiency in thiamin can lead to beriberi, a condition characterized by weakness, nerve damage, and heart problems. Good sources of thiamin include whole grains, legumes, and pork.

Riboflavin, or vitamin B2, is important for energy production, cellular function, and the metabolism of fats, drugs, and steroids. It also helps maintain healthy skin and eyes. A deficiency in riboflavin can lead to sore throat, inflammation of the mouth, and skin disorders. Good sources of riboflavin include dairy products, eggs, green leafy vegetables, and fortified cereals.

Niacin, or vitamin B3, is essential for energy production, DNA repair, and the metabolism of fats and carbohydrates. It also helps maintain healthy skin and nervous system function. A deficiency in niacin can lead to pellagra, characterized by dermatitis, diarrhea, and dementia. Good sources of niacin include meat, fish, nuts, and grains.

Pantothenic acid, or vitamin B5, is important for the synthesis of coenzyme A, which is essential for fatty acid metabolism. It also helps produce and metabolize proteins and fats. A deficiency in pantothenic acid is rare but can lead to fatigue, irritability, and numbness. Good sources of pantothenic acid include meat, eggs, whole grains, and avocados.

Biotin, also known as vitamin B7, is essential for the metabolism of carbohydrates, fats, and proteins. It supports healthy hair, skin, and nails. A deficiency in biotin can lead to hair loss, skin rashes, and neurological issues. Good sources of biotin include eggs, nuts, seeds, and fish.

Phosphorus is essential for the formation of bones and teeth, as well as the production of energy in the body. It also plays a role in the synthesis of DNA and RNA. A deficiency in phosphorus can lead to bone pain, muscle weakness, and fatigue. Good sources of phosphorus include meat, fish, dairy products, and nuts.

Selenium is a trace mineral that plays a critical role in metabolism and thyroid function. It acts as an antioxidant, helping to protect cells from damage. A deficiency in selenium can lead to heart disease, infertility, and immune dysfunction. Good sources of selenium include Brazil nuts, seafood, and whole grains.

Iodine is essential for the production of thyroid hormones, which regulate metabolism, growth, and development. A deficiency in iodine can lead to goiter, hypothyroidism, and developmental issues in children. Good sources of iodine include iodized salt, seafood, dairy products, and eggs.
