Where neurotransmitters and micronutrients team up in your body
Neurotransmitters are chemicals that help your brain and nerves communicate, and they rely on micronutrients to be made. This chart shows how amino acids like L-phenylalanine and L-tryptophan turn into key neurotransmitters with the right vitamins and minerals.
1️⃣ Dopamine, Norepinephrine, Epinephrine (from L-phenylalanine) These "feel-good" and stress-response chemicals start with L-phenylalanine, turning into L-tyrosine, then L-DOPA, and finally dopamine. Iron, niacin, and vitamins C and B6 help this process. Dopamine becomes norepinephrine with copper and niacin, and epinephrine with SAMe and magnesium.
🟢 Example: Low vitamin C might slow dopamine production, affecting mood.
🟢 Example: Magnesium helps turn norepinephrine into epinephrine for energy during stress.
2️⃣ Serotonin and Melatonin (from L-tryptophan) L-tryptophan turns into 5-HTP, then serotonin, a mood and sleep regulator, with vitamins B6, C, and minerals like zinc. Serotonin becomes N-acetylserotonin with folate and SAMe, then melatonin with SAMe, aiding sleep.
🟢 Example: Low B6 can reduce serotonin, making you feel down.
🟢 Example: More tryptophan at night supports melatonin for better sleep.
3️⃣ Micronutrient Support Vitamins (like B6, C) and minerals (like iron, magnesium) act as helpers, ensuring each step works. Without them, your brain can’t produce enough neurotransmitters.
🟢 Example: Iron deficiency might stall dopamine, leading to fatigue.
🟢 Example: Calcium and folate keep serotonin and melatonin on track.
Your brain uses these nutrients to build neurotransmitters, starting with amino acids from food. The process happens in nerve cells, with vitamins and minerals acting like tools to keep mood, energy, and sleep balanced.
