Best Multivitamins for Autumn and Winter Immunity in 2026
A Vitabiotics daily multivitamin, an effervescent vitamin C and zinc formula, and a one-a-day omega-3 and vitamin D capsule compared — to help carers and care homes choose the right immune support this autumn and winter.
Every fitness account, pharmacy shelf and GP waiting room fills up with the same message every September: it’s time to think about immune support before winter properly sets in. For carers and care home staff buying on behalf of residents, or families stocking up for older relatives, the choice usually comes down to three types of product — a broad daily multivitamin, a fast-acting vitamin C and zinc top-up, and an omega-3 and vitamin D capsule.
Distributing Care compared three of the current UK best sellers in this space, drawn directly from Amazon’s own sales rankings rather than marketing copy, so the picks below reflect what shoppers are actually buying — not just what’s promoted the loudest.

Frequently asked questions
Quick answers to what readers ask most about immune support supplements.
Do multivitamins actually help prevent colds and flu?
Multivitamins don’t prevent colds or flu outright, but correcting a genuine deficiency in vitamins C, D or zinc can help the immune system work as it should. The NHS advises everyone in the UK consider a 10 microgram vitamin D supplement through autumn and winter, since sunlight isn’t strong enough for most people to make enough on their own.
What’s the difference between a daily multivitamin and a vitamin C and zinc supplement?
A daily multivitamin, such as Wellwoman 50+, is designed to cover a broad range of vitamins and minerals every day. A vitamin C and zinc formula like Berocca is a more targeted, fast-acting top-up, often used at the first sign of a cold or during periods of extra demand on the immune system. Many households use one as a daily baseline and keep the other on hand for flare-ups.
Is cod liver oil safe for older adults on blood thinners?
Anyone taking anticoagulant medication such as warfarin should speak to their GP or pharmacist before starting a fish oil or cod liver oil supplement, since high-dose omega-3s can affect blood clotting. This is exactly the kind of check care home staff should build into a resident’s medication review before adding any new supplement.
When should carers start immune support supplements for winter?
Most UK health guidance points to starting vitamin D and general immune support supplements around October, when the clocks change and sunlight levels drop, and continuing through to early spring.
Can care home residents take multiple supplements from this list together?
It depends on what else a resident is already taking. A multivitamin and a vitamin C and zinc tablet can usually be taken alongside each other, but stacking multiple products risks going over the safe upper limit for a nutrient like zinc or vitamin A. Always check with a pharmacist or the resident’s GP before combining supplements, particularly in a care home setting where residents may already be on prescribed vitamin supplementation.
