About Standard Process

Standard Process is a whole food supplement and vitamin brand founded in 1929 and headquartered in the US. It operates as an independent company. With 97 years in business, Standard Process is one of the more established supplement brands.

Product Specialization

Standard Process specializes in whole food supplements and vitamins. Their product range includes a variety of supplements designed to support different aspects of health, such as digestive health, immune function, and overall wellness.

Testing & Certifications Explained

Standard Process is GMP Certified, which means they adhere to Good Manufacturing Practices set by regulatory agencies. However, there is no evidence that Standard Process is third-party tested. Third-party testing provides an extra layer of assurance for consumers, as it involves independent labs verifying the contents and purity of supplements. The absence of third-party testing means consumers must rely solely on the brand's own quality control measures.

How Standard Process Compares

Many supplement brands now prioritize third-party testing to build consumer trust. For example, Thorne Research (Trust Score: 92/100) and Klean Athlete (Trust Score: 88/100) are both third-party tested supplements, and have higher trust scores than Standard Process. These brands invest in independent verification to demonstrate product quality and safety.

Buying Guidance

Given the low Standard Process trust score and lack of third-party testing, consumers should exercise caution. If considering Standard Process products, carefully review the product labels and be aware of the "Standard Process recall" history. Consult with a healthcare professional before use.
