ALWAYS check labdoor.com before buying any supplements! Demand a 3rd party testing proof (Certificate of Analysis) from your favorite brand. If you’re a brand and need help with transparent quality control just email us.
Bad Omega3s are essentially rancid oil. 3rd party labs can measure totox (total oxidation, lower the better), not everyone reports their results, so I run my own 3rd party testing (I pay @Labdoor). This is by far the lowest oxidation I've seen, coming from @PureEncaps - it's an expensive Omega3 but very clean. Zero affiliation, just sharing for the knowledge. 🙏 cc: @foundmyfitness
