How do I ensure the purity and quality of fish oil supplements?
To ensure the purity and quality of fish oil supplements, I recommend looking for products that are certified by a reputable third-party organization like NSF International or the United States Pharmacopeia (USP). These organizations conduct rigorous tests to ensure the product meets specific quality standards. Additionally, choose supplements that are molecularly distilled and tested for contaminants such as mercury, lead, and PCBs. Lastly, consider the supplement's source, as fish oil sourced from wild-caught, smaller fish is typically more sustainable and potentially more effective.
To ensure the purity and quality of fish oil supplements, consider the following:

1. Choose reputable brands: Opt for well-known brands that have a history of producing high-quality supplements. These brands should also have a transparent manufacturing process and adhere to strict quality standards.

2. Look for third-party testing: Check if the fish oil supplement you're considering has been tested by an independent organization. This will provide assurance that the product meets certain purity and quality standards.

3. Check for purity certificates: Look for fish oil supplements that have been certified by organizations like the International Fish Oil Standards (IFOS) or the United States Pharmacopeia (USP).
