When buying CBD or hemp oil, quality checks are essential. Look for lab-tested products, as reputable brands provide third-party lab results to confirm potency and purity. The hemp source matters too; organically grown, non-GMO hemp is best. Review the ingredient list to avoid unwanted additives. Understanding the extraction method is also key—CO2 extraction is a clean, safe option. Lastly, check product ratings and reviews to gauge customer satisfaction and trustworthiness before making a purchase.
