The Back-to-School Immunity Checklist for UK Parents (2026)
Every September, 7 million UK children walk into classrooms and swap germs with impressive efficiency. You can't bubble-wrap them — but you can head into term with the basics covered. Here's the honest checklist, hype removed.
The foundations beat any supplement
Sleep, a varied diet, outdoor time and handwashing do more for school-term resilience than anything in a bottle. Supplements are the top-up, not the foundation. With that said, the UK has one genuinely official recommendation…
Vitamin D: the one the NHS actually recommends
UK government advice is that children (like adults) should consider a daily vitamin D supplement from October through winter, because UK sunlight can't cover it. Starting the habit in September makes it stick. Drops, sprays and kids' gummies all work — pick the format your child will actually take. Vitamin D contributes to the normal function of the immune system.
The sensible extras
- A kids' multivitamin as an insurance policy for picky eaters.
- Vitamin C — contributes to normal immune function; abundant in fruit, easy to top up.
- Friendly bacteria — kid-formulated options are popular for term time.
- Routine reset: September is also when bedtimes collapse. If sleep is the struggle, see our melatonin-free sleep guide — and note melatonin itself is prescription-only in the UK.
What to skip
Mega-dose anything, "immune-boosting" blends with claims too good to be true, and adult formulas halved. Children's products are dosed for children — stick to them and follow the label.

FAQ
When should we start? Early September for routine-building; vitamin D officially from October, but starting early does no harm at label doses.
Gummies or drops? Whichever your child takes reliably. Consistency beats format.
My child eats well — do they need anything? Possibly just vitamin D in winter, per UK advice. A varied diet covers most of the rest.
