Vitamin B7, or biotin, is essential for metabolism, particularly in breaking down carbohydrates, fats, and proteins. It's also associated with healthy hair, skin, and nails, plays a role in the nervous system, and helps in fatty acid synthesis. It's found in foods like eggs, nuts, and seeds.*

Vitamin B12 is essential for red blood cell production, a healthy nervous system, DNA synthesis, energy metabolism, and potentially mood regulation. It's primarily found in animal-based foods and is crucial for overall health.*
