FAQ
Can I take immune boosters every day?

Do I need extra boosters during cold seasons?
Many people increase intake of vitamin C, elderberry, or zinc during seasonal changes, but daily consistency is key for long-term support.
Are these safe with other supplements?
Generally yes. Just avoid doubling high-dose vitamin C, zinc, or vitamin D across multiple products unless guided by a provider.
