Do We Really Need Supplements Every Day?

It is one of the most searched nutrition questions online: Do I really need supplements every day?
The honest answer is: not everyone does—but many people can benefit from them when they are used wisely. Supplements are meant to supplement the diet, not replace real food, sleep, movement, or healthy habits. The NIH defines dietary supplements as products intended to supplement the diet, and both the NIH and Huberman Lab emphasize that they should be part of a broader health strategy, not the foundation of it.
