Short answer: a large share of your immune system lives in and around your gut, and your gut bacteria help train and regulate immune responses. Supporting gut health is one sensible lever for everyday immune resilience — alongside sleep, nutrition and stress management — though no supplement makes you immune to infections.

How is the gut linked to immunity?

Roughly 70% of immune tissue is associated with the gut, and the bacteria living there help "educate" immune cells and keep responses balanced. A diverse, well-fed microbiome is associated with healthier immune function, while disruption — from poor diet, repeated antibiotics or chronic stress — can tip the balance.

The everyday basics that matter most

Unglamorous but powerful: enough sleep (short sleep measurably weakens immune defences), a fibre-diverse diet that feeds good bacteria, regular movement, managing stress, and staying hydrated. These do more for day-to-day resilience than any single product.

Where supplements fit

On top of the basics, gut and nutrient support can help. Our Immunity Pre+Probiotic Melts combine pre- and probiotics with immune-relevant nutrients, and our Supergreens Antioxidant Juice helps top up plant nutrients and antioxidants on busy days. These support general immune health — they don't prevent or treat infections, and persistent illness should be checked by a doctor.

FAQ

Can probiotics stop me getting sick? They may support immune resilience for some people, but they don't make you immune to infections.
What's the most important thing for immunity? Sleep, a varied fibre-rich diet, and stress management are the foundations.
When should I see a doctor? Frequent or severe infections warrant medical assessment to rule out underlying causes.
