The COVID-19 pandemic may no longer dominate the headlines, but the virus continues to circulate and impact vulnerable groups every winter. The COVID vaccine UK 2025 booster programme is now underway — and many people are asking who’s eligible, how it works, and what else they can do to protect their health.
In this blog, we’ll break down the current UK rollout, why vaccination is only one part of winter resilience, and how supporting your nutrition with TRINITY can help maintain strong immune defences.
🧬 COVID Vaccine UK 2025: Who Is Eligible?

🤔 Why Nutrition Is Still Critical
The COVID jab provides targeted immune protection against circulating strains. But your overall immune strength depends on daily nutritional status — especially as multiple viruses (flu, RSV, cold strains) overlap in winter.
Nutrient gaps are particularly common in the UK during colder months:
-
Vitamin D₃ – crucial for regulating immune cell activity; low sunlight = widespread deficiency
-
Vitamin C – antioxidant protection and collagen support for respiratory health
-
Zinc – important for antiviral defence and tissue repair
-
Selenium – key to optimal immune signalling and thyroid support
-
B-complex – energy for immune cells under viral stress
Even mild deficiencies can reduce resilience and slow recovery.
🌿 TRINITY: Smart Supplementation for Winter Defence
TRINITY is a 3-part multivitamin system, designed to optimise absorption and fill nutrient gaps — a key need when food intake or nutrient density drops in winter.
✅ Immune nutrients covered: Vitamin D₃, C, Zinc, Selenium
✅ Designed for synergy: Iron paired with Vitamin C, calcium separated from magnesium
✅ Time-optimised: Morning B-complex for energy, evening Magnesium Glycinate for rest and recovery

A: No — vaccines target specific strains, while supplements support baseline immunity. They work best together.
Q: Which vitamins matter most for immune health?
A: Vitamin D₃, Vitamin C, Zinc, Selenium, and B-complex are essential for immune resilience.
Q: Do I need supplements if I’m otherwise healthy?
