Overview
•All ingredients are GRAS and dosages align with established safe upper limits: vitamin C up to 2,000 mg/day, zinc 40 mg/day, vitamin D 4,000-10,000 IU/day per NIH guidelines.
•Potential mild GI side effects from high vitamin C (1,000 mg) or zinc (25 mg) in sensitive individuals, but bisglycinate form improves tolerability.
•Zinc may interact with antibiotics (e.g., quinolones, tetracyclines) and diuretics; vitamin D with certain heart medications—consult physician if on meds.
•Suitable for most healthy adults; caution for pregnancy (vitamin D dosage high—limit to 4,000 IU/day per ACOG) and children under 18.
•Vegan formulation with no major allergens; low contamination risk from NOW Foods' GMP-certified manufacturing.
•Long-term use safe at recommended dose but monitor vitamin D levels to avoid hypercalcemia; not for those with kidney issues.
