You don’t need to track your micronutrient intake while flexible dieting, but you’ll still want to maximize your chances of meeting the daily recommended values by eating a variety of foods and possibly taking a multivitamin. 


Because fiber-rich foods tend to be high in many vitamins and minerals, if you’re meeting your fiber requirements and eating plenty of colorful fruits and vegetables, this should automatically take care of your micronutrients. 


If you believe you’re at risk of falling short of the daily recommended values, taking a multivitamin supplement can act as "nutrient insurance" to fill any gaps that might exist. There are also a few cases where supplementation may be more warranted, such as:


  • You don’t eat dairy:

    • You may need to supplement calcium and vitamin D

  • You’re vegan:

    • You’ll need to supplement B12
