Testing & Certifications Explained

SD Naturals claims to use third-party testing, but does not specify which certifications they hold. This means that while the company asserts its products are tested by an independent lab, there is no way to verify the standards or rigor of that testing. Consumers should be aware that without a recognized third-party certification, the extent and reliability of the testing cannot be confirmed. Therefore, it is difficult to definitively say "is SD Naturals third-party tested" to a satisfactory degree.

Another competitor, Life Extension (trust score 80/100, publishes certificates of analysis), demonstrates greater transparency. SD Naturals needs to improve transparency and obtain recognized certifications to compete effectively with these brands.
