Disclaimer

This guide provides general therapeutic ranges and does not replace licensed medical care. Consult a healthcare practitioner if pregnant, breastfeeding, taking medications, or managing chronic MCAS or histamine-related conditions.
Suggested use may vary depending on individual needs and goals. Some blends are used short term for acute support, while others may be taken over a longer period for chronic or ongoing wellness support, or at a lower maintenance dose once balance is achieved.
We recommend starting with the suggested dosage and reassessing after the initial support period to determine whether continued use is needed, whether the dosage should be adjusted, or whether it’s appropriate to take a break. Everyone’s body and situation are unique, and needs may change over time.
For ongoing or long-term use, or if symptoms persist, we encourage checking in with your healthcare provider or qualified practitioner to ensure the blend continues to be the right fit for where you are currently at.
As always, listen to your body, start low and slow when introducing any new product, and adjust as needed with professional guidance.
