Adults: 500–1000 mg Vitamin C and 10–25 mg Zinc daily, preferably with food. Children (6–12 years): consult a physician for appropriate dosage. Pregnant and breastfeeding women: seek medical advice before use. Consistent daily intake supports immune strength and recovery.
Safety & interactions+
Supplementation should be avoided by individuals with known hypersensitivity to vitamin C or zinc compounds. Use cautiously in people with kidney disorders, hemochromatosis, or those taking antibiotics or diuretics, as interactions may affect mineral balance or absorption.
What it helps with
How it works in your protocol
Most supplements are a guess. Agen earns every capsule from your own data — the measure → analyze → act loop.
Measure
The Band tracks your HRV, sleep and resting heart rate; the app reads your stress load across the day.
Analyze
When recovery dips and stress climbs, Agen flags adaptogenic support — and scores the evidence behind it.
Act
It enters your daily protocol at the right dose, dispensed by the Robot each evening.
What the science says
Every claim scored by evidence strength — including the ones that aren’t there yet.
Early signals only — the honest answer is the evidence isn't conclusive yet. We'll update this the moment it is.
