Vitamin C, D and zinc: what truly helps immunity (and the myths)
Supplements are easy to buy, harder to use wisely. This guide separates myths from practical steps and puts the focus back on food, sleep, and routine.
Quick Answer:
Vitamin C, D and zinc can help, but only as part of a bigger plan: protein + fiber meals, sleep, and movement. Avoid mega doses without a clear reason.

Why supplements aren’t the first line
Vitamin C: food first
Vitamin D: be smart and check
Zinc: useful, not all the time
