What can a blood test and other factors tell you about mood?

A wide range of factors can affect your mood and mental wellbeing. For example, feeling low, irritable, or finding it hard to concentrate can be linked to nutrient deficiencies and hormonal imbalances. You might also struggle to sleep well or feel very tired during the day.

Blood tests related to mood


Vitamin D

Vitamin D acts on areas of your brain linked to mental wellbeing. And good levels are linked to a reduced risk of low mood, anxiety, and depression.


Vitamin B12

Vitamin B12 is essential for a healthy brain and nervous system. If you don't get enough vitamin B12 it can change the way you feel and think, make you more irritable, and lead to feelings of anxiety and depression.


Folate (vitamin B9)

Folate is important for your mental wellbeing and helps protect you from memory loss and dementia (declining brain function) as you age.


Omega-3 fats

Omega-3 fats are important for many different aspects of your brain health. Having optimal levels might be linked to a reduced risk of developing depression.



Testosterone is a sex hormone that plays an important role in maintaining a normal mood. Low testosterone levels are linked to irritability, poor concentration, and low mood.


Thyroid function

Your thyroid is a gland in your neck that produces hormones that control your body's growth and metabolism. An overactive thyroid or underactive thyroid causes hormonal imbalances that can cause symptoms like tiredness, low mood, symptoms of anxiety and depression, and difficulty sleeping.



Oestrogen is one of the main sex hormones in women. Oestrogen affects the area of your brain that helps regulate your emotions. Changes in your oestrogen levels during your cycle, after birth, and leading up to menopause are linked to low mood, difficulty concentrating, and feelings of anxiety.
