When should you monitor your intake of vitamins and minerals?

You should monitor your intake of vitamins and minerals if you have specific health conditions, dietary restrictions, or if you're pregnant or breastfeeding, as these factors can increase your nutritional needs. Additionally, if you're following a restrictive diet or have symptoms of deficiency, such as fatigue or weakness, it's important to assess your intake. Regular check-ups with a healthcare provider can also help determine if you need to adjust your vitamin and mineral consumption.
