How Does Nutrition Affect Mental Health & Anxiety?

There is an intricate yet unique connection between psychological wellness and nutrient deficits. Scientists are still researching to determine the exact pathways. However, low dietary intake or poor metabolism might worsen pre-existing mental health conditions and decrease emotional well-being. The following are a few noteworthy effects:

  • Deterioration of mental illnesses
  • Decreased use of coping techniques to deal with stress
  • Reduced mood & decreased ability to concentrate and focus
  • Fatigue

What Nutritional Deficiencies Cause Anxiety?

Essential nutrients are critical for controlling mood, energy, and mental health. Here, we have highlighted some points to help you learn how nutritional deficiencies impact anxiety and mental health. It's important to note that individual responses to nutrient deficiencies can vary, and not everyone will experience the same symptoms.

B Group Vitamins

The B nutrients (B6, B9, B12) are vital in energy metabolism and state of mind control. This lack of nutrient can cause:

  • Weariness
  • Sadness
  • Irritability

Lack of B vitamins prevents the body from producing serotonin - a neurotransmitter essential for controlling mood.

Iron (Ferrous)

Serotonin and dopamine are two "feel-good" neurotransmitters. They are influenced by iron. It is necessary for:

  • Transfer of oxygen
  • Creation of neurotransmitters

It is vital to maintain an appropriate amount of iron through food. Low iron levels might trigger symptoms similar to depression.


Calcium is linked not only to skeletal health but also to Its significant influence on mental health. An insufficient amount of calcium can lead to:

  • Rapid exhaustion
  • Sleeplessness
  • Depression

These indications emphasise how crucial it is to keep calcium levels at their ideal range for mental health.

Vitamin D

A lack of vitamin D affects:

  • Mood control
  • Sleep habits
  • Gene expression

Vitamin D is connected to some neurological illnesses. Sunlight exposure is crucial for lessening the probability of melancholy and other brain disturbances.


Magnesium is a natural mood stabiliser. Its deficit triggers:

  • Mood swings
  • Exhaustion
  • Nausea

Maintain appropriate magnesium levels and protect mental health. You can do so by staying away from things that deplete magnesium, such as:

  • Processed foods
  • Coffee

Omega-3 Fatty Acids

Omega-3 fatty acids are vital for brain health and decreasing inflammation. They reduce anxiety and elevate mood.

Inadequate consumption of omega-3 fatty acids debilitates the integrity of nerve cell membranes and worsen anxiety.


Zinc is essential for:

  • Brain health
  • Enzymatic functions
  • Mood management
  • Cognitive performance

The correlation between anxiety, depression, and low zinc levels highlights the need to consume enough zinc.
