Pyridoxinic acid, also known as vitamin B6, is an essential nutrient required for our body's proper functioning. It plays a crucial role in various biochemical reactions, such as metabolism, neurotransmitter synthesis, and immune system modulation. This water-soluble vitamin comes with several synonyms, including pyridoxol, pyridoxamine, and pyridoxal. These compounds are all biologically active forms of vitamin B6 and are involved in the activation of numerous enzymes. Pyridoxinic acid can be found in foods like fish, poultry, bananas, and chickpeas. Adequate intake of these synonyms is crucial to prevent vitamin B6 deficiency, which can lead to symptoms like anemia, dermatitis, and weakened immune function.
