Magnesium regulates the nervous system and supports calm, restorative sleep. It influences GABA and NMDA receptor activity, helping reduce neuronal hyperexcitability and promoting relaxation. 

In integrative psychiatry, specific forms of magnesium such as magnesium glycinate is preferred because of being well absorbed and gentle on the digestive system.

Magnesium is often combined with stress reduction techniques, therapy, and lifestyle modifications to enhance resilience to anxiety, mood dysregulation, and sleep disturbances.

Key benefits:

• Promotes relaxation and restful sleep

• May reduce anxiety and irritability

• Supports overall brain function

These amino acids serve as precursors to key neurotransmitters, including dopamine, norepinephrine, and epinephrine, which are essential for motivation, alertness, and cognitive performance.

By supporting the production of these neurotransmitters, tyrosine and phenylalanine help the brain respond effectively to stress, maintain focus, and regulate mood.

Adequate levels can enhance mental clarity, attention, and energy, particularly during periods of high cognitive demand or stress.

Key benefits:

• Enhances cognitive function

• May improve symptoms of depression and anxiety

• Supports brain and immune health

Iron is essential for oxygen transport and energy metabolism, and it supports enzymes involved in dopamine, norepinephrine, and serotonin synthesis.

Deficiency can lead to fatigue, poor concentration, and mood disturbances, making adequate levels critical for cognitive and emotional health.

Integrative psychiatry uses iron supplementation strategically, guided by lab results, to safely support mental energy, attention, and mood regulation.

Key benefits:

• Supports attention and cognitive function

•  

L-Theanine promotes calm and relaxation without sedation by enhancing GABA, dopamine, and serotonin activity.

It can improve attentional control and cognitive focus, making it useful for individuals managing stress, anxiety, or ADHD-related challenges.

Choline is an essential nutrient that serves as a building block for acetylcholine, a key neurotransmitter involved in learning, memory, and overall cognitive function.

CDP‑Choline (Citicoline) is a highly bioavailable form that efficiently supports brain cell membrane integrity and neurotransmitter production.

​

In integrative psychiatry, choline or CDP‑Choline is often used alongside therapy, lifestyle interventions, and other targeted nutrients to optimize cognitive function, enhance memory, and support mental resilience.

​

Key benefits:

• Supports acetylcholine synthesis for learning and memory
