Frequently Asked Questions
Can supplements replace prescription allergy meds?
Supplements can help reduce inflammation and improve resilience but they are not direct replacements for prescription antihistamines or steroid sprays in acute or severe allergies. Use non-prescription supplements as complementary supports and consult your provider before stopping prescribed treatments.
How long before I’ll notice results?
Timing varies: quercetin/bromelain users may notice reduced symptoms in days to weeks, while glandulars and hormone-support supplements often take several weeks of consistent use. Track symptoms and give a stack 4–12 weeks to evaluate effectiveness.
Are there safety concerns or interactions?
Yes. Enzyme products and glandulars are generally safe for many people, but pregnenolone affects hormone pathways so check with your clinician if you have hormone-sensitive conditions or take prescription meds. Also watch for stomach upset or GI effects and stop if you have adverse symptoms.
