Vitamin B6 is the best known of the B vitamins. The body is unable to synthesize it and stores it in too small quantities in the muscles and liver, which makes a regular intake through the diet essential. The recommended daily allowance (RDA) for vitamin B6 is 1.8 mg per day for adults and 2 mg per day for pregnant women (third trimester of pregnancy) or nursing mothers.
Pyridoxine is mainly present in sprouted cereals (3.3 mg/100 g), yeast (2.6 mg/100 g), egg yolk, meat (0.52 mg/100 g) and fish (tuna: 0.85 mg/100 g). In contrast, most fruit and vegetables are low in vitamin B6.
Although it is the best known of the B vitamins, vitamin B6 is also the one that performs the greatest number of functions.
- Like most B vitamins, it contributes to energy metabolism and fatigue reduction.
- It is also an essential element of the cerebral metabolism since it is involved in the synthesis of certain neurotransmitters in stressful situations, and it also stimulates the absorption of magnesium, a mineral that is essential for the proper functioning of the body.
- Vitamin B6 contributes to the normal synthesis of cysteine and the metabolism of homocysteine, two amino acids involved in the body's methylation reactions. It is also involved in the normal metabolism of proteins and glycogen.
Other demonstrated roles of vitamin B6 in vital mechanisms:
- Regulation of hormonal activity;
- Functioning of the immune system;
- Formation of red blood cells.
