What can a blood test tell you about your sleep quality?

Understanding what’s going on inside your body can give you insights into your sleep quality. For example, poor sleep is sometimes linked to a nutrient deficiency or an issue with your liver health.

Combined with GP-reviewed results and evidence-based ways to improve your sleep, take your health into your own hands with a home blood test.

What's included in this blood test?

Vitamin D

Vitamin D supports your bone, muscle, and immune health. Low vitamin D levels are linked to worse sleep quality and a higher risk of sleep disorders, like insomnia and restless legs syndrome.

Omega-3 fats are essential for your brain to function properly and low levels are linked to sleep problems.
