Ingredient risk
Contains restricted ingredients
⛔ Red — banned or high-risk ingredients
Auto-flagged from PHIG regulatory data. Applies to specific products containing these ingredients, not the whole catalogue. Flags show countries named in the source data.
GDM prevention — 4 g/day from first trimester in high-risk women [2]
⚠️ Yellow — use with caution or restricted in some markets
Severe deficiency (<0.50 mmol/L) causes secondary hypocalcemia and hypokalemia that will not correct until magnesium is repleted first [1].
Granulomatous diseases (sarcoidosis, TB) — unregulated extra-renal CYP27B1 can cause life-threatening hypercalcemia even at standard doses [2][21]
Sensory neuropathy from chronic high-dose B6 (>200 mg/day) — presents as numbness, ataxia. Can be irreversible. Often self-prescribed by patients for PMS or carpal tunnel [3]
Wernicke encephalopathy: classic triad (confusion, ophthalmoplegia, ataxia) is present in only 16% of cases — any ONE element in an at-risk patient warrants IV thiamin [5]
Chronic zinc >40 mg/day without copper causes copper deficiency: anemia, neutropenia, myeloneuropathy [1].
Nitrous oxide anesthesia in subclinically B12-deficient patients can precipitate acute combined degeneration — always check B12 before elective procedures using N₂O [5]
