Overview
•Zinc: 50 mg a day is over the 40 mg/day upper limit (IOM (NIH ODS)) and the 25 mg/day limit (EU SCF/EFSA). 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.
•Vitamin D: 125 mcg a day. Above the 4,000 IU daily upper limit; common for correcting low levels; test 25(OH)D if taking long term.
•Daily zinc intake at 50 mg for more than four weeks can impair copper absorption and induce secondary copper deficiency unless paired with 2 mg of supplemental copper.
•Contraindicated in individuals with pre-existing hypercalcaemia or conditions predisposing to high calcium levels (such as primary hyperparathyroidism or sarcoidosis).
•Take with a substantial meal to avoid common high-dose zinc side effects like transient nausea, abdominal cramps, or gastric irritation.
