Vitamin B6 plays many roles in your overall health. Your body uses vitamin B6 to metabolize amino acids. One group of these amino acids, neurotransmitters, can directly influence how well your nervous system functions.

The development and efficiency of red blood cells and muscles are dependent on vitamin B6. In extreme cases, vitamin B6 deficiency can lead to anemia. Vitamin B6 also influences how efficiently your body converts fats and sugars into energy. Dietary vitamin B6 is found in most meats, potatoes, spinach, and bananas.

Athletigen has found that the NBPF3 gene plays a role in the system that clears vitamin B6 from your body and certain variants can lead to lower or normal levels.


Signs of vitamin B6 deficiency include sores on your lips and in corners of your mouth, swollen tongue, depression, confusion, difficulty sleeping, and anemia.

Athletes with joint injuries commonly over-supplement with vitamin B6 as a means to reduce discomfort. Ironically, this can result in chronic nerve pain. Certain variants of the NBPF3 gene may increase the rate that vitamin B6 is used or broken down, resulting in a decrease in vitamin B6 levels.

Use Athletigen’s Nutrition Report to better understand how your body metabolizes vitamin B6 and to get unique recommendations on what to do if you have a reduced response to vitamin B6.
