- Malabsorption syndromes: Conditions like Crohn's disease or celiac disease may impair zinc absorption.
- Increased requirements: Pregnant and breastfeeding women, as well as growing children, may have higher zinc needs.
- Chronic illnesses: Diseases such as diabetes or liver disease can affect zinc levels.
Cost Ranges for Zinc Supplements
- Over-the-counter zinc supplements: $5 - $20 for a monthly supply, depending on the brand and dosage.
- Zinc-fortified foods: These may be slightly more expensive than non-fortified options but vary widely.
