Labels may also include warnings or cautions relevant to certain populations. Keep in mind that supplement-related fatigue normal in adults is a topic that has been studied, but evidence remains limited and mixed.

Check for clear ingredient names and amounts
Look for expiry or best-before dates
Note any allergen statements or warnings
