I found some info on taking high levels of zinc, for what it’s worth: https://www.nutritionletter.tufts.edu/ask-experts/q-i-take-50-milligrams-of-zinc-daily-but-it-looks-like-you-should-take-only-40-milligrams-per-day-is-it-ok-to-continue-what-are-the-consequences-of-too-much-zinc/

“High zinc intakes (150-450 milligrams per day) have been reported to inhibit copper absorption, sometimes resulting in copper deficiency, associated anemia, reduced immune function, and reduced levels of high-density or ‘good’ cholesterol. Intake of 80 milligrams per day of zinc in the form of zinc oxide for an average of 6.3 years in the Age-Related Eye Disease Study (AREDS) has been associated with a significant increase in hospitalizations for genitourinary issues. Even moderately high intakes of zinc of about 60 milligrams per day for up to 10 weeks have been reported to reduce a copper-containing enzyme (a marker of copper status). Zinc supplements also have the potential to interact with several types of medications (such as antibiotics and diuretics). As such, be sure to discuss your zinc intake with your healthcare provider.”
