According to the International Fish Oil Standards (IFOS), only a small percentage of omega-3 supplements on the market achieve its prestigious 5-star rating, representing the highest possible standard for quality and purity. This designation signifies a product that has undergone rigorous, independent, third-party testing to verify its contents, safety, and freshness.

According to a 2020 analysis by PBS, some tested dietary supplements exceeded safe consumption limits for heavy metals like arsenic, lead, and cadmium, highlighting a serious consumer risk. This raises the critical question of how to test for heavy metals in supplements and what steps consumers can take to ensure product safety.

According to Little Spoon, their Babyblends product line received Clean Label Project certification in February 2022, signifying that the products are tested for contaminants including heavy metals and pesticides. This certification confirms Little Spoon's adherence to a higher standard of food purity and transparency for their products.

Over 700 million dietary supplement packages have featured the USP Verified Mark since its inception, providing consumers with a vital sign of quality assurance. A USP supplement is one that has voluntarily undergone rigorous third-party testing by the U.S. Pharmacopeia to confirm its identity, potency, purity, and performance. This certification helps consumers navigate a largely unregulated market with confidence, ensuring that what's on the label is actually in the bottle.

According to the U.S. Environmental Protection Agency, most fish oil supplements contain negligible amounts of mercury due to advanced purification processes.

According to the NSF, the nutritional supplement market has grown dramatically, with many products lacking independent verification. For health-conscious consumers, this highlights the importance of asking: is Thorne iron third party tested? The answer, supported by multiple certifications, provides significant peace of mind.

NSF International's own resources state that certification verifies products are free from *harmful levels* of contaminants, not that they are completely free of all traces. Does NSF mean no heavy metals? The reality is more nuanced and involves rigorous testing against established safety limits to protect public health.

In the United States, dietary supplements are not pre-approved or strictly regulated by the FDA, making third-party testing a critical measure for consumer safety and trust. This is precisely why many consumers ask, "Does AG1 do 3rd party testing?" to evaluate the product's safety and quality claims.

According to a 2025 Harvard Medical School report, some melatonin gummies were found to contain up to 347% more melatonin than advertised, highlighting the critical need for independent testing. This is why knowing which 3rd party testing companies for supplements are trustworthy is essential for consumer safety and confidence.

According to a 2022 report by the Clean Label Project, many protein powders were found to contain heavy metals, pesticides, and other contaminants. Therefore, understanding **what seal should you look for on protein products to ensure they are free of contaminants?** is a crucial step for any health-conscious consumer.
