Imbalances in our neurotransmitters can cause depression, anxiety, OCD, problems sleeping, and a wide range of other troublesome symptoms.
Neurotransmitters have nutrient based precursors including amino acids, in particular phenylalanine, tyrosine, GABA (gamma aminobutyriuc acid), and tryptophan. Also iron, BH4, B vitamins (active forms of B12, folate and B6), copper (don't supplement with copper without balancing with zinc) and vitamin C are needed to build neurotransmitters from these amino acids.
As an example, the amino acid tryptophan is required for your body to make serotonin. B vitamins, magnesium, and other vitamins and minerals are also required. Serotonin is then converted into melatonin. Serotonin is well known for playing a role in depression, and melatonin in sleep.
Eating foods that contain nutrients that are involved in neurotransmitter metabolism may help improve your mood and help you get a good night's rest.
