What is one of the reasons individuals should exercise caution when purchasing supplements?

Individuals should exercise caution when purchasing supplements primarily because there may be inconsistencies in the product and label. This is a significant reason to be wary since the supplement industry is not as strictly regulated as pharmaceuticals. Labels might not accurately reflect the contents of the product—either in terms of dosage or the actual ingredients contained. Such inconsistencies can lead to unintended health risks or ineffective results, as consumers may unknowingly ingest harmful substances or inadequate amounts of beneficial ingredients.

Additionally, the lack of stringent regulation means that some products may not go through rigorous testing for safety and efficacy, which further emphasizes the importance of exercising due diligence when selecting supplements. This understanding helps consumers make informed decisions and promotes their health and safety.
