Immune Support – Daily Defense & Resilience

The immune system is a complex network of cells and processes that works around the clock. Like every system in the body, it needs a steady supply of specific nutrients to function normally — and those nutrients have to come from food or food supplements every day. The Immune Support collection brings together the Nutri-Leaf formulas built around the three nutrients with authorised immune-function claims: vitamin C, zinc and selenium.

How nutrients support normal immune function

Under EU Regulation (EU) No 432/2012, three vitamins and minerals in our range carry the authorised claim "contributes to the normal function of the immune system": vitamin C, zinc and selenium. Vitamin C contributes to the normal function of the immune system and to the protection of cells from oxidative stress — a normal by-product of energy metabolism that the immune system's own activity also generates. Zinc contributes to the normal function of the immune system. Selenium contributes to the normal function of the immune system. These are the exact, authorised wordings — no stronger claim exists for these nutrients.

Key nutrients for immune function

• Vitamin C — contributes to the normal function of the immune system and to the protection of cells from oxidative stress.
• Zinc — contributes to the normal function of the immune system (10 mg per capsule, 100% NRV in Immunity Complex).
• Selenium — contributes to the normal function of the immune system (50 µg per capsule, 91% NRV in Immunity Complex).

What's in this collection

Vitamin C 1000 mg is a two-ingredient formula: L-ascorbic acid in a plant-based capsule shell, providing 1,000 mg vitamin C per daily capsule (1,250% NRV). Immunity Complex combines vitamin C, zinc and selenium with three plant ingredients — echinacea, ginger and rosehip extract. The botanicals are listed as ingredients; the immune benefit comes from the three authorised nutrients.

Immune nutrition across the year

Immune nutrition is not a winter topic — the immune system works every day of the year. A consistent supply of vitamin C, zinc and selenium — nutrients that contribute to the normal function of the immune system — matters in every season, alongside the basics: a varied diet, adequate sleep, regular movement and hydration.

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
