1. Vitamin B1 (Thiamine)

• Nervous System: Thiamine plays a critical role in nerve function by helping in the production of energy and neurotransmitters that the nervous system uses to communicate. It aids in the conduction of nerve impulses and supports cognitive functions.
• Beauty: While not directly related to skin, hair, or nails, a deficiency in thiamine can cause fatigue and lack of energy, which can indirectly affect skin radiance and overall health appearance.
• Anemia: Thiamine helps the body use carbohydrates as energy and is essential in the formation of red blood cells, helping to combat certain types of anemia caused by deficiency.

2. Vitamin B2 (Riboflavin)

• Nervous System: Riboflavin supports brain function by aiding the production of cellular energy, which is crucial for maintaining nervous system activity.
• Beauty: Riboflavin is essential for maintaining healthy skin, hair, and nails. It helps in the repair and maintenance of tissues, especially in areas with rapid cell turnover like the skin.
• Anemia: It assists in iron metabolism and the formation of red blood cells, helping prevent anemia caused by riboflavin deficiency.

3. Vitamin B3 (Niacin)

• Nervous System: Niacin supports nerve function by converting nutrients into energy for nerve cells and by helping repair DNA in neurons.
• Beauty: Niacin has anti-inflammatory properties and is commonly used in skincare products to treat acne and improve skin elasticity. It can also reduce fine lines and dullness, making skin appear more youthful.
• Anemia: Niacin aids in the formation of hemoglobin, which can help in conditions of anemia by improving oxygen transport in the blood.

4. Vitamin B5 (Pantothenic Acid)

• Nervous System: This vitamin is crucial for the synthesis of coenzyme A, which is needed for the proper function of the nervous system, especially in the production of neurotransmitters.
• Beauty: Pantothenic acid is important for skin health by aiding in the repair of skin cells and promoting hydration, which can help reduce the signs of aging and improve complexion.
• Anemia: It supports the production of red blood cells, helping prevent certain types of anemia by ensuring proper oxygen transport in the body.

5. Vitamin B6 (Pyridoxine)

• Nervous System: Vitamin B6 plays a crucial role in the production of neurotransmitters, including serotonin, dopamine, and gamma-aminobutyric acid (GABA), all of which are essential for regulating mood, sleep, and cognitive functions. It helps in nerve cell communication and supports brain development.
• Beauty: Vitamin B6 contributes to skin health by regulating hormones that may cause acne and other skin issues. It also supports protein metabolism, which is crucial for hair and skin repair and growth.
• Anemia: Pyridoxine is essential for the production of hemoglobin, the protein in red blood cells that carries oxygen. A deficiency in vitamin B6 can lead to microcytic anemia, characterized by fatigue and weakness.

6. Biotin (Vitamin B7)

• Nervous System: Biotin supports the function of the nervous system by aiding in the synthesis of neurotransmitters and the metabolism of fats and carbohydrates, which are crucial for energy production in nerve cells.
• Beauty: Biotin is well-known for promoting healthy hair, skin, and nails. It enhances keratin production, improving hair strength, skin health, and nail growth.
• Anemia: Though less directly involved in red blood cell formation, biotin still plays a role in maintaining overall body health, which includes combating anemia caused by metabolic issues.

7. Vitamin B12 (Methylcobalamin)

• Nervous System: Methylcobalamin is vital for maintaining nerve health. It supports the myelin sheath that surrounds and protects nerves, ensuring efficient nerve impulse transmission. It also plays a role in preventing nerve damage.
• Beauty: Vitamin B12 contributes to overall skin health by promoting cell regeneration, reducing inflammation, and improving skin tone. It is often used in beauty products to combat dark spots and pigmentation.
• Anemia: Methylcobalamin is critical in the production of red blood cells, helping to prevent megaloblastic anemia, which can cause fatigue and weakness.

8. L-Carnitine

• Nervous System: L-carnitine plays a role in brain function by reducing oxidative stress and improving mitochondrial function in nerve cells. It is sometimes used to improve memory and cognition.
• Beauty: L-carnitine helps reduce oxidative stress, which can damage skin cells and accelerate the aging process. It is also involved in fat metabolism, which could contribute to overall body health and fitness.
• Anemia: While L-carnitine is not directly involved in red blood cell production, it plays a role in maintaining energy levels, which can help alleviate some symptoms of anemia such as fatigue.
