Ascorbic acid is better known as which vitamin?

Ascorbic acid is widely recognized as Vitamin C, an essential nutrient that plays a significant role in various bodily functions. It is crucial for the synthesis of collagen, which is necessary for the health and repair of tissues, including skin, cartilage, and ligaments. Additionally, Vitamin C functions as a powerful antioxidant, protecting cells from damage caused by free radicals, and it actively supports the immune system.

Beyond its roles in maintenance and immune function, Vitamin C aids in the absorption of iron from plant-based foods and is involved in the conversion of the amino acid phenylalanine to the amino acid tyrosine, which is important for the production of neurotransmitters.

While the other vitamins mentioned have their distinct roles and significance in the body—such as B1 being important for energy metabolism, D being crucial for calcium absorption, and B12 being vital for red blood cell formation—the association of ascorbic acid is unequivocally with Vitamin C. This makes it a standout choice among the provided options.
