Supplements vs. a Whole-Food Diet
Before you can even think about a supplement, it’s crucial to understand a foundational principle of health: a supplement is, by definition, a supplement.

The most significant and lasting health benefits come from a diet that is rich in a variety of nutrient-dense, whole foods, such as fruits, vegetables, whole grains, and legumes. A supplement, on the other hand, is a targeted tool that can be used to address a specific deficiency or to achieve a specific health goal.
A. The Power of a Whole-Food Diet
A whole-food diet is a diet that is rich in a variety of unprocessed, natural foods. These foods are a source of a variety of vitamins, minerals, antioxidants, and fiber, and they are a cornerstone of a healthy and balanced diet. The synergy of a variety of nutrients in a whole-food diet is a powerful force that a supplement cannot replicate.
