How Selenium Supports Immunity: Are You Getting Enough?

Wondering why you keep getting sick?

Repeated coughs, colds, or slow recovery from viruses are frustrating and all too common, especially during UK winter. One often overlooked reason is low selenium—a trace mineral crucial for your immune system to work its best.

What has selenium got to do with my immune defences?

Selenium acts like a ‘key’ for your immune cells, helping them respond effectively to bugs and protect your body from infection. Deficiency can lower your resistance, while the right amount boosts:

• White blood cell activity
• Antibody production
• Inflammation control

That’s why some people with low selenium are more likely to catch infections or have worse symptoms.

Are you at risk of not getting enough selenium?

UK soils are naturally low in selenium, which can mean home-grown produce contains less. You could be at higher risk if you:

• Eat a vegan or vegetarian diet
• Have digestive disorders like coeliac or Crohn's
• Avoid foods like eggs/fish due to allergies

Unsure if this applies to you? Testing is the safest way to check your levels and make informed decisions.

Is there a simple way to check selenium status?

Absolutely. With the Mayfield Clinic Home Selenium Blood Test Kit, you just use a small finger-prick sample at home (sent to our UK lab). Results arrive securely in 4 days with clinician interpretation and actionable advice.

What if I’m low in selenium?

Don’t panic! Try these steps:

• Add Brazil nuts, mushrooms, eggs, tuna or chicken to your meals
• Review vitamin/mineral needs with a GP
• Try a personalised action plan after your blood test

Supplements should only be considered after professional advice, as excess selenium can pose its own risks.
