RiskLow Risk
Overview
•All B-vitamins and electrolytes in this formulation are water-soluble with low toxicity risk at stated dosages, well below UL limits (e.g., niacin 25 mg vs. 35 mg UL).
•Potential mild GI upset from high B-vitamin doses like thiamin 100 mg or B6 3 mg, but rare in healthy adults; vitamin C 200 mg may cause diarrhea in sensitive individuals.
•No significant drug interactions for this product, though high B6 could theoretically affect levodopa absorption; consult doctor if on medications.
•Safe for general adult use but not recommended for pregnancy/breastfeeding without medical advice due to high folate (400 mcg) and B12 levels; avoid in children.
•Gluten-free and yeast-free as stated, low allergen risk; USP verified ensures quality and minimal contamination concerns.
•Long-term use safe for most, but monitor B6 intake to avoid neuropathy at chronic high doses (though 3 mg here is low).
