Description
Immune Boost Supplement — Vitamin C, Zinc & Vitamin D Support
Immune Complex combines Vitamin C, Zinc Picolinate, and Vitamin D (Calciferol) — three of the most well-established nutrients for immune function, working through complementary mechanisms rather than a single pathway. Zinc supports epithelial barrier integrity and antiviral cellular defences, Vitamin C protects and helps restore the epithelial barrier while supporting immune cell function, and Vitamin D helps regulate immune signalling and induces the body’s own antimicrobial peptides.
Halaal certified. Made in South Africa. 60 gelatin-free veggie capsules.

A Note on Daily Zinc Intake
Zinc Picolinate is a chelated form of zinc, and the elemental zinc content is lower than the total compound weight — roughly 21%. At the adult dose of 2 capsules, this works out to approximately 42mg of elemental zinc daily, just above the commonly cited tolerable upper intake level (40mg/day in the US, 25mg/day in the EU) for sustained daily use. This is a modest difference, not a large one, but if you’re taking other zinc-containing supplements alongside this product, it’s worth keeping your total daily zinc intake in mind.
Key Benefits
- Immune support — Vitamin C, Zinc, and Vitamin D each play distinct, well-established roles in both innate and adaptive immunity, including epithelial barriers, cellular defence, and antibody function
- Antiviral activity — zinc has been shown to bolster host cell antiviral defences, restrict viral replication, and support the ciliated respiratory epithelium’s function against viral damage
- Anti-inflammatory — zinc has documented anti-inflammatory action in the respiratory tract, while Vitamin C helps modulate inflammatory signalling triggered by immune activity
- Skin barrier function — zinc supports epithelial barrier integrity, and Vitamin C acts as a cofactor in collagen synthesis, which stabilises epithelial and skin barrier structure
How to use
Adults: take 2 capsules daily. Children under 12 years: 1 capsule daily. Consistent daily use supports the body’s baseline immune function rather than acting as a rapid, one-off remedy.
Who it’s for
Adults and children looking for foundational daily immune support, particularly during periods of increased exposure (temperature changes, crowded spaces, travel) or seasonal illness. Not intended to diagnose, treat, cure, or prevent any disease, including viral or respiratory infections. If pregnant, breastfeeding, or on chronic medication, consult your healthcare provider before use.
Frequently Asked Questions
What does Immune Complex contain?
Each capsule contains 400mg Vitamin C, 400IU Vitamin D (Calciferol), and 100mg Zinc Picolinate (approximately 21mg elemental zinc). The adult daily dose of 2 capsules provides 800mg Vitamin C, 800IU Vitamin D, and approximately 42mg elemental zinc.
Is the zinc dose in this product safe for daily use?
At the adult dose, elemental zinc intake is approximately 42mg/day, slightly above the commonly cited upper intake level of 40mg (US) or 25mg (EU) for ongoing daily use. This is a modest excess, not a large one, but if you’re using other zinc-containing supplements too, it’s worth being mindful of your total daily intake.
Can children take this product?
Yes, the label recommends 1 capsule daily for children under 12 years, compared to 2 capsules for adults.
Does this help prevent colds and flu?
Vitamin C, Zinc, and Vitamin D each have research supporting a role in reducing the incidence or severity of upper respiratory tract infections, particularly in people with insufficient baseline levels of these nutrients. This product is not intended to diagnose, treat, cure, or prevent any specific illness.
Is this product suitable for vegetarians?
Yes. The capsules are gelatin-free veggie capsules.
Is this product Halaal certified?
Yes, it’s Halaal certified.
