Iron Absorption: It enhances the absorption of iron from plant-based sources.

Immune Function: It boosts the immune system and helps the body fight infections.

Summary

Adermin is a synonym for vitamin \(B_6\), which supports amino acid metabolism, neurotransmitter production, and hemoglobin synthesis.

Cyanocobalamin is a form of vitamin \(B_{12}\), essential for DNA synthesis, red blood cell production, and nerve function.

Biotin (vitamin \(B_7\)) helps in the metabolism of nutrients and supports healthy skin, hair, and nails.

Ascorbic acid is vitamin C, which acts as an antioxidant and is involved in collagen production, iron absorption, and immune defense.

So, Adermin is the correct name for vitamin B6, and each vitamin plays a unique and essential role in maintaining health.
