Frequently Asked Questions
Can I store these supplements in the car during summer?
Choose only shelf-stable products and keep them out of direct sun. Silver Fern, Toniiq, and Codeage are formulated for shelf stability, but prolonged exposure to extreme heat can degrade potency—store them in a cooler bag or inside a shaded compartment and rotate stock regularly.
How soon will electrolytes like SaltStick FastChews work?
Chewable electrolyte tablets are designed for rapid absorption; many users feel relief from cramps and improved hydration within 15–30 minutes. They’re best used with water and during periods of heavy sweating or heat exposure.
Should I start a high-potency probiotic like Toniiq before a trip?
If you’re new to high-CFU products, start several days before travel at a lower dose to assess tolerance. High-potency formulas can cause temporary digestive changes for some people; beginning early reduces the chance of discomfort during the trip.
