Vitamin B6 (abundent in pistachios, tuna, turkey, chickpeas, and avocado) is known to help cells absorb magnesium ( a nutrient found in kale and other dark leafy greens, pumpkin seed, salmon, and soybeans). Multiple studies conducted on children with autism and ADHD showed that when children took magnesium and Vitamin B6 supplements together, they displayed improved social interaction and communication and less hyperactivity.  In addition, there is some evidence that the combination of magnesium and vitamin B6 can reduce PMS symptoms.
