For some people their could be a hidden genetic cause to their PN due to MTHFR mutation. Which is the gene mutation for folate metabolism. It simply means you cannot use regular folic acid due to this mutation and require the active form folinic acid.

Folinic Acid has many benefits for neurological disorders, elevated homocysteine levels, supports healthy methylation reactions in your body and supports your immune system and DNA repair and replication.

Hope this helps everyone.
