Which of these vitamins produces the collagen responsible for skin, bone, teeth and cartilage production?

Vitamin C is essential for collagen synthesis, which is required for the formation and maintenance of skin, bones, teeth, cartilage, and blood vessels. Without adequate vitamin C, the body cannot produce strong collagen, leading to scurvy. Vitamin A supports vision and immunity, while B vitamins (including B12) are primarily involved in energy metabolism and neurological function.
