Quick take

Immune-support supplements can help you maintain resilience during the challenging UK winter by supporting your body’s natural defences.

Key picks

• Vitamin C — May help maintain normal immune function during winter stress.
• Vitamin D3 — Supports immune response, especially with limited sunlight exposure.
• Zinc — Can contribute to normal immune support and cell function.
• Elderberry — Traditionally used to support the body’s natural defences.
• Probiotics — May help balance gut flora, which is linked to immune health.
• Beta-glucans — Early research suggests potential support for immune cells.
• Garlic extract — Used in traditional practices for general wellbeing.

Who it helps / when to be careful

These supplements may suit adults looking to support their immune system during busy or cold periods, or those with limited sunlight in winter. They may also appeal to people with demanding lifestyles or seasonal pressures.

Not all supplements are suitable for everyone—pregnant or breastfeeding individuals, those with health conditions, or anyone taking medication should consult their GP or pharmacist before use. Children and older adults should seek tailored advice before starting new supplements.

How to use

1. Take supplements with or after food for best absorption.
2. Pair with a balanced diet rich in fruit and vegetables.
3. Space out supplement intake from hot drinks like tea or coffee.
4. Be consistent with daily routines, especially during winter months.
5. Store supplements in a cool, dry place out of direct sunlight.

What to pair or avoid

• Pair vitamin D with healthy fats (like avocado or olive oil) for optimal absorption.
• Avoid taking zinc and iron supplements together, as they may compete for absorption.
• Reduce high sugar intake, which can impact immune health.
• Support with good sleep and regular physical activity.
• Limit alcohol, which may affect nutrient absorption and immunity.
