Vitamin B6 (Pyridoxine)
For this reason, patients with Parkinsons disease on levodopa therapy should avoid high B intake unless they are also taking carbidopa (which prevents this interaction)
severe thiamine deficiency, while rare, can cause Wernickes encephalopathy in hyperemesis gravidarum, and inadequate B is associated with anemia and neurologic issues in the newborn
However, with the current environments we live in and the poor quality and mass production of food, especially animal products at the moment, everyone is at risk of having below sufficient levels of Vitmain B12
To gauge improvement, track specific issues you had before, for instance, frequency of mouth sores (which can occur with B deficiencies), or numbness in feet, or level of fatigue on a 10-point scale
Riboflavin (B) and pantothenic acid (B) have fewer documented interactions
