South African winter is short but it lands hard — the whole country catches the same three viruses between Youth Day and the spring derbies. The immune protocol that works isn't the one you start when your throat tickles. It's the one running since May.
The honest science of "immune boosting"
You can't "boost" an immune system the way marketing implies — you can only remove its handicaps. The winter handicaps are specific: lower vitamin D from weaker sun, depleted vitamin C turnover during infections, dry indoor air punishing the mucosal barrier, and the stress-sleep erosion that suppresses everything. Each one is addressable.
The base layer (all winter)
- Buffered vitamin C, daily — regular intake (not rescue-dosing) is linked in the research to shorter, milder colds — a support measure, not a cure. The buffered form lets you hold a meaningful daily dose without stomach burn.
- Vitamin D3 — Johannesburg winter sun barely clears the threshold for skin synthesis, and indoor lives miss most of it. The cheapest correction in the immune toolkit.
- Sleep, guarded ruthlessly — one short night measurably drops natural killer cell activity. Everything else on this list is decoration by comparison.
The escalation layer (when it's going around)
- Vitamin C, stepped up and split — absorption saturates per dose, so 3–4 smaller doses beat one large one.
- Mullein — when the chest gets involved, the traditional lung herb earns its keep: loosens, soothes, calms the cough cycle.
- Immune Plus — our broad-spectrum formula for households that want one bottle covering the antioxidant + mineral fronts.
The calendar

|---|---|
| May | Start base layer — C + D3 daily |
| Jun–Jul | Full base; escalation layer at first household sniffle |
| Aug | Hold base; start the hay-fever protocol mid-month (the seasons overlap) |
