Takeaways

• 😀 Vitamin B1 (thiamine) is water-soluble and plays a crucial role in maintaining skin health, converting carbohydrates into energy, and aiding protein and fat metabolism.
• 😀 Sources of vitamin B1 include whole grains, rice, meat, dairy, eggs, and legumes, which are essential for heart health and nervous system function.
• 😀 Deficiency in vitamin B1 can lead to skin issues, dryness, scaling, beriberi, and digestive disorders.
• 😀 Vitamin B2 (riboflavin) is vital for metabolic processes and helps in the growth of skin, hair, and nails, acting as a coenzyme in various bodily functions.
• 😀 Good sources of vitamin B2 are fresh vegetables, soybeans, egg yolks, and dairy products, while deficiency can cause weakened immunity and skin problems.
• 😀 Vitamin B3 (niacin) generates energy and aids in carbohydrate, fat, and protein metabolism, also supporting blood sugar regulation and migraine relief.
• 😀 Foods rich in vitamin B3 include yeast, liver, poultry, fish, and sweet potatoes, with deficiency potentially causing muscle cramps and digestive issues.
• 😀 Vitamin B5 (pantothenic acid) supports enzymatic reactions and nutrient metabolism, promoting communication between the central nervous system and brain.
• 😀 Sources of vitamin B5 are found in meats, dairy, kidneys, and various plant foods, and deficiency can lead to dry skin and insomnia.
• 😀 Vitamin B6 (pyridoxine) is important for energy production, metabolism, and the immune response, with deficiency causing skin issues and insomnia.
• 😀 Vitamin B7 (biotin) acts as a coenzyme in metabolic reactions and is crucial for synthesizing fatty acids and amino acids, with sources including liver, egg yolks, and certain fruits.
• 😀 Vitamin B9 (folate) is essential for new cell synthesis, red and white blood cell formation, and preventing neural tube defects in pregnancy, found in leafy greens and animal products.
• 😀 Vitamin B12 (cobalamin) is necessary for energy metabolism, DNA formation, and platelet production, sourced from animal products; deficiency can lead to anemia and fatigue.
