What Are the Side Effects of Thorne Immune Support Stack?
Always consult your health practitioner if in doubt.
RiskHigh Risk
Overview
•Zinc: 90 mg a day is over the 40 mg/day upper limit (IOM (NIH ODS)) and the 25 mg/day limit (EU SCF/EFSA) (about 2.3 times the limit). Long-term intake above this limit can cause copper deficiency, which can lead to anaemia, low white blood cells and nerve problems. Suppie lowered this product's safety rating by one level for this reason.
•Mild gastrointestinal distress or nausea can occur if zinc picolinate or ascorbic acid is ingested on an empty stomach.
•Supplements containing high-dose zinc and vitamin C should be spaced at least 2 to 4 hours apart from certain prescription medications, notably quinolone and tetracycline antibiotics.
•Generally well tolerated across healthy adults; pregnant or nursing individuals should confirm total daily vitamin D and zinc intake across all supplement sources with their clinician.
