Same stack, three commitment levels.
~80% of the stack benefit at moderate cost..The core combination — covers the main mechanisms.
Full mechanism + edge-case redundancy..Comprehensive coverage of every documented pathway.
Most cold supplements only work in the first 24-48 hours of symptoms. This stack covers the highest-evidence rapid-action options: zinc lozenges (within 24 hours of symptoms cuts cold duration), elderberry (flu duration), vitamin C at bowel-tolerance dose, and propolis throat support.
What it's for
Within 24 hours of symptom onset. First sign of cold/flu (throat tickle, body aches, fatigue).
Not for:After day 3 — most evidence is for early intervention. Bacterial infections need antibiotics. COVID-19 — follow current medical guidance.

Pair with — diet, workout, activity
The supplement is half the lift. The rest is daily.
🍽️ Diet that fits
Whole foods, varied colours, sufficient protein (0.8–1.2 g/kg), fermented foods for microbiome health
Ultra-processed foods, refined sugars, excess alcohol, inflammatory seed oils
3 balanced meals with protein at each. Avoid eating within 2 hours of sleep.
🏋️ Workout that fits
Combination of aerobic (3×/week) and resistance training (2×/week)
Completely sedentary days — even 30 minutes of walking changes metabolic markers
Exercise and supplementation share many downstream pathways. One amplifies the other.
🚶 Activity & lifestyle
Daily sunlight exposure (15–20 minutes), adequate hydration (2–3L), stress-reduction practice
Processed food consumption, prolonged sitting, late-night screen time
7–9 hours sleep; all supplements work better with adequate rest.
