Calcium deficiency and celiac disease are closely linked, as celiac sufferers often struggle with nutrient absorption. To ensure proper calcium intake, it's essential to consume calcium-rich foods, such as leafy greens, dairy, and fortified products. Additionally, supplements can help fill in any nutritional gaps. It's also important to follow a strict gluten-free diet to promote gut healing and improve nutrient absorption. Regular check-ups with a healthcare professional can help monitor and maintain a healthy calcium level.
