It’s no secret that vitamins are essential for maintaining good health. Among the different groups of vitamins, we find those of the B group, which form all 8 B vitamins.

Their synergy is essential to optimize cognitive functions, stimulate the secretion of neuromodulators and improve emotional balance. These are vitamins B1 (thiamin), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 ​​(pyridoxine), B8 (biotin), B9 (folic acid or folate), and B12 (cobalamin).

This last substance necessary for our body is water-soluble, which means that it dissolves in water. Vitamin B12 is the most complex and largest vitamin in the B group. This organic molecule is essentially stored in the liver. 

“The human liver contains approximately 50% of the stock. This constitutes a reserve used by the organism for 3 to 5 years”, indicates the Lescuyer laboratory on its website. However, it can also be found in the heart, pancreas, and brain.
