Seasonal Immune Support: A Practical Guide for Autumn and Winter

Why the Autumn Question Keeps Coming Up

As the days shorten and indoor time increases, the question "should I do something for my immune system?" returns every year. The honest answer starts the same way every year too: the immune system does not switch on in October. It runs continuously, and its normal function depends on the same things in every season — a varied diet, normal sleep, regular movement, and adequate intake of the nutrients it uses.

What the Approved Wording Actually Covers

Three nutrients in the Nutri-Leaf range carry an authorised immune-system claim:

• Vitamin C — contributes to the normal function of the immune system.
• Zinc (10 mg, 100% NRV) — contributes to the normal function of the immune system.
• Selenium (50 µg, 91% NRV) — contributes to the normal function of the immune system.

The wording is "normal function" — not "stronger defence", not "fewer colds". A supplement supports the immune system's normal operation where intake is short. It does not upgrade a system that is already working normally.

The Season Checklist That Costs Nothing

• Vegetables and fruit daily — the baseline for vitamin C intake.
• Normal sleep — sleep patterns are among the best-documented lifestyle factors linked to immune function.
• Movement and daylight — outdoor time matters for more than vitamin D; it anchors sleep and activity.
• Hand hygiene and fresh air — the boring basics of the season, still the most practical.

When a Supplement Fits In

A supplement becomes relevant when the diet leaves a real gap — for example a winter menu low in vegetables and fruit, or a plant-heavy diet with limited zinc sources. The Nutri-Leaf Immunity Complex combines vitamin C from rose hip extract (40 mg, 50% NRV) with zinc, selenium, echinacea, ginger, and L-histidine, each declared on the label. Note the label warning: avoid taking additional selenium-containing or zinc-containing food supplements alongside it — and never exceed the recommended daily intake.

Start with the checklist, then look at the label. See the Immunity Complex Capsules for the declared formula, and what to know about zinc and immunity.

Food supplements are not a substitute for a balanced and varied diet and a healthy lifestyle.
