Every autumn, the UK rolls out its annual flu vaccine programme to protect vulnerable groups and reduce pressure on the NHS. In 2025, the flu jab remains an essential tool against seasonal flu β but itβs not the only way to strengthen your defences.
Alongside vaccination, optimising your nutrition with a comprehensive multivitamin like TRINITY can help ensure your immune system has the nutrients it needs to function at its best.

π€ Why Nutrition Still Matters During Flu Season
The flu jab helps prevent infection and serious illness from specific influenza strains. But the immune system is complex β it requires daily nutritional support to produce antibodies, regulate inflammation, and recover from viral stress.
Nutrients most at risk of deficiency in the UK winter include:
-
Vitamin Dβ β produced in the skin via sunlight, but almost all adults in the UK are deficient during winter months
-
Vitamin C β supports white blood cell activity and antioxidant defence
-
Zinc β vital for immune signalling and wound healing
-
Selenium β essential for viral defence and thyroid function
-
B-complex vitamins β fuel immune cell energy and regulate stress response
Even if youβre vaccinated, nutrient gaps can leave your immune system underperforming.
