Collection: Immune System VitaminsPremium daily supplements designed for long-term vitality

They're vitamins, minerals and botanicals that help support your immune system's normal function. Low levels of vitamin A, folic acid, B vitamins, vitamin C, iron and zinc can all affect normal immune function - so your most basic immune policy should be a healthy diet rich in fresh vegetables, oily fish and whole grains, with supplements like a good multivitamin and mineral formula supporting from there.

They keep your body's defences properly supplied with the nutrients that immune function depends on: vitamins C and D, zinc, selenium, iron, folate and vitamin A all contribute to the normal function of the immune system. They're particularly valued through the winter months and times of stress or poor diet, when nutritional gaps are most likely to open up.

Build from the foundations up. Vitamin D is arguably the most important in the UK our D3 comes in strengths up to 4000iu while time-release vitamin C and zinc form the classic everyday immune pairing, both contributing to normal immune function. For more comprehensive support, our Beta Glucans Immune Complex adds vitamin D and zinc to one of the market's strongest 1,3 1,6 beta glucan blends. And because much of the immune system sits in and around the gut, Acidophilus live bacteria or our Multivitamins & Minerals with Probiotic cover that angle too. A good multivitamin quietly covers all the basics in one.

Honest answer: not in the way the marketing suggests. When we talk about 'immune boosting', what we're really referring to is taking action to support optimal immune function - keeping the system properly nourished so it can do its job, rather than supercharging it beyond normal. That's what a healthy diet, good sleep, regular exercise and sensible supplementation genuinely deliver. Anything promising more deserves scepticism.

Very much so - a large proportion of your immune system is located in and around the gut, which is why taking good care of your gut health matters for immunity. That's the thinking behind pairing immune nutrients with live bacteria: our Acidophilus Plus+ range provides billions of friendly bacteria with a prebiotic base, and our Multivitamins & Minerals with Probiotic combines both jobs in one capsule.

Yes - immune nutrients are designed for daily use, and consistency is what makes them worthwhile, since your immune system needs steady nourishment rather than occasional heroics. A daily multivitamin like our Multi A-Zinc, or targeted options like vitamin D, C and zinc, slot easily into a morning routine. As always, follow label doses and check with your GP if you take regular medication.

We're honest about what immune support really means nourishing normal function, not miracle 'boosting' and our comprehensive range reflects it, with ingredients to suit different needs: vitamin D3 in multiple strengths up to 4000iu, time-release vitamin C, zinc, selenium, garlic, one of the market's strongest Beta Glucans complexes, and combination formulations from Vitamin C & Zinc chewables to probiotic-multivitamins. Nutrient levels are clearly labelled throughout, making product selection easy, and everything is GMP quality assured.
