Quick Guidance

Pick what matches your situation - start with one change, then build. If you want extra certainty, at-home immune testing can highlight nutrient status and stress/inflammation patterns to fine-tune dosing and timing.

  • First sign / scratchy throat → Immune Charge+ Throat Spray for targeted, on-the-go support.
  • Daily foundation → Daily Multi Vite for baseline nutrition; pair with Gut Balance, Gut Immune Powder, Optimum Gut Defense, Biome Gut to support the gut–immune axis. Antioxidant Defense and D3K2 to support healthy immune system function.
  • High-potency C (defense & recovery) → Ultra Vitamin C or Vitamin C (liposomal); dose with meals and increase gradually to tolerance.
  • Travel & “everyone’s sick” season → Keep Immune Charge+ Throat Spray handy; maintain PB-40 Gut Balance consistently.
  • Everyday nourishment → Super Greens for gentle phytonutrients/fiber (titrate slowly).
  • If energy dips during/after illness → Return to basics first (sleep, fluids, protein); resume Daily Multi Vite and Vitamin C before adding anything new.

Frequently Asked Questions

1) What should I take at the first sign I’m getting sick?
Reach for Immune Charge+ Throat Spray for local support, add Ultra Vitamin C or Vitamin C (liposomal) with meals, rest, hydrate, and keep meals simple. Many people also keep PB-40 Gut Balance steady through the week.

2) What’s a good daily immune routine?
Start with Daily Multi Vite, PB-40 Gut Balance (probiotic), and Vitamin C. Layer Super Greens if you want more phytonutrients/fiber (go slow). Use Immune Charge+ Throat Spray situationally (travel, crowds, scratchy throat).

3) Is liposomal vitamin C different from regular vitamin C?
Liposomal C is designed for enhanced absorption and gentler GI tolerance for some people. Regular C works well too - choose the form you tolerate and can take consistently.

4) How long should I take a probiotic?
Give PB-40 Gut Balance 2–4 weeks of consistent, same-time daily use before judging. Many keep a daily probiotic long-term, especially during travel or high-stress seasons.

5) Can I combine these products?
Yes, just add one change at a time. A common stack is Daily Multi Vite + PB-40 Gut Balance + Vitamin C, with Immune Charge+ Throat Spray used as needed. Track how you feel and adjust every 1–2 weeks.

6) Any tips for dosing vitamin C?
Take with food and increase gradually; back down if you notice GI upset. Split doses across the day during recovery periods.

7) Are these safe with my medications or health conditions?
Immune products are generally well-tolerated when used as directed. If you are immunosuppressed, pregnant/breastfeeding, or take prescription medications, consult your clinician before starting new supplements.
