Nutrition and Anxiety: Nutrient Deficiencies That May Be Contributing to Your Symptoms

Anxiety can be influenced by many physical, emotional, and environmental factors. While stress and mental health play a major role, nutrition and certain nutrient deficiencies may also affect mood, energy levels, and nervous system function.

Maintaining balanced nutrition may help support emotional well-being and improve the body’s ability to respond to daily stress.

How Does Nutrition Influence Anxiety?

The brain depends on specific nutrients to produce neurotransmitters related to mood regulation, such as serotonin and dopamine. When nutrition is inadequate or unbalanced, nervous system function may be affected.

In addition, factors such as excessive sugar intake, high caffeine consumption, and irregular eating schedules may contribute to symptoms like nervousness, irritability, and fatigue.

B Vitamins

B vitamins support brain function and energy production. Common food sources include:

Omega-3 Fatty Acids
