Lifestyle and mental wellbeing

A wide range of factors can affect your mental wellbeing. Sometimes, a nutrient deficiency or hormonal imbalance might lead to:

  • feeling low
  • feeling irritable
  • difficulty concentrating
  • poor sleep
  • tiredness

What can this test tell you?

This finger-prick blood test will measure a range of factors that are important for helping your mental wellbeing. You’ll also get insights into other areas of your health and what to focus on so you can take health into your own hands

What's included in this test?


Active 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.


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.

Note: If you have sarcoidosis (an inflammatory disease) or a condition that affects your parathyroid glands (these regulate calcium in your body), it can make it difficult to interpret your vitamin D results. So in this case, it's best to work with your doctor and get specialist input.


Thyroid profile

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

This test measures your:

thyroxine (T4) — the main hormone produced by your thyroid

thyroid-stimulating hormone (TSH) — a hormone that regulates your thyroid



HbA1c refers to glycated haemoglobin. When the glucose (sugar) in your blood rises, it binds to haemoglobin in your red blood cells. These cells live for about 3 months, so a HbA1c test measures your average blood sugars over the last few months. This is a useful way to measure your risk of pre-diabetes and diabetes, but optimal HbA1c levels are linked to a lower risk of developing depression.
