How do I take it when I feel something coming on?
For quick support, many people take 1–2 capsules every hour. Don't go over 2 in an hour. Your practitioner can fine-tune that for you. For everyday upkeep, it's 2 capsules a day.
What makes this different from a plain vitamin C?
It pairs the immune nutrients — zinc and vitamins A, C, B12, and B5 — with a botanical blend. That blend is elderberry, echinacea, andrographis, and astragalus. So several kinds of support work together in one capsule.
Can my child take it?
Only with your practitioner's guidance. They'll confirm the right fit and amount for a child. When in doubt, ask your guide first.
Can I take it with my medication?
Check with your practitioner first, especially if you take any prescription. We're glad to help you start that conversation.
Is there anything to watch with the vitamin A?
Yes. Vitamin A is fat-soluble, which means it can build up over time. Don't take more than the recommended amount. And talk to your practitioner first if you're pregnant or could become pregnant.
How long can I take it?
It's made for two things: short, focused immune support and everyday upkeep. Your practitioner will help you decide what's right for you.
