How does this complex differ from taking folic acid alone?

The main difference is that the formula combines three B vitamins at once: folic acid (B9), vitamin B12 and vitamin B6. This is not just a set "to make up the numbers": the components are linked to one another in metabolism.

Vitamin B12 works in tandem with folates and helps them take full part in processes related to blood formation and the nervous system. When B12 is lacking, the absorption and use of folic acid can be impaired, so taking them together is often chosen as a more balanced option than folic acid by itself.

Vitamin B6 is needed for amino acid metabolism, is involved in the formation of red blood cells and in homocysteine metabolism, and also in the synthesis of substances involved in transmitting signals between nerve cells.

This combination is convenient when you want to cover your basic need for these three vitamins with one product rather than choosing them separately. If you already take other B-vitamin complexes, it is worth assessing the total dosage with a specialist in advance so as not to double up on the same components.
