Product Specialization

Natrol specializes in supplements like melatonin, vitamins, 5-HTP, and biotin. They are widely recognized for their melatonin products, which are often used to support sleep.

Testing & Certifications Explained

Natrol is GMP Certified, which means their manufacturing processes adhere to Good Manufacturing Practices as defined by regulatory agencies. However, there is no evidence that Natrol products are third-party tested. Third-party testing provides an extra layer of assurance regarding the purity, potency, and safety of supplements, as it involves independent labs verifying the product's contents and absence of contaminants.

How Natrol Compares

Compared to competitors such as NOW Foods (Trust Score 82/100) and Thorne Research (Trust Score 95/100), Natrol's Trust Score is lower, primarily due to the lack of third-party testing. Both NOW Foods and Thorne Research offer a wider range of third-party tested supplements. Life Extension (Trust Score 78/100) also exceeds Natrol's score with more transparent testing practices.

Buying Guidance

Given Natrol's Trust Score of 60/100, consumers should carefully consider whether Natrol is safe for their individual needs. Purchase Natrol products from reputable retailers to ensure authenticity. Consumers particularly interested in third-party tested supplements should seek alternatives.
