What is the maximum zinc dosage per day stated in the material?

• A. up to 40ml/d
• B. up to 40mg/d
• C. up to 400mg/d
• D. up to 4ml/d

Answer: (A)

Understanding dosing units is key here. The material provides zinc as a liquid with a defined strength per milliliter, so the daily maximum is given as a volume rather than a mass. Up to 40 milliliters per day is the limit, meaning you’d only know the exact milligrams per day if you know the concentration (mg per mL) of that liquid and multiply by the 40 mL. The mg-per-day options assume a fixed mass without referring to the product’s concentration, which isn’t how this material presents the maximum. So using the stated volume of 40 mL per day aligns with how the product is dosed in the material.
