The Claim

Flavor additives in omega-3 supplements are associated with elevated anisidine values, which may reflect either real oxidative degradation or interference from aldehyde-like compounds in flavorings, complicating accurate safety assessment.

In plain English

Flavor additives in omega-3 supplements are linked to higher anisidine values, which can result from either oxidation of the oil or chemical interference from the flavoring compounds, making it harder to determine if the supplement is safely preserved.

See the scientific wording

Flavor additives in omega-3 supplements are associated with elevated anisidine values, which may reflect either real oxidative degradation or interference from aldehyde-like compounds in flavorings, complicating accurate safety assessment.

Why this might work

Flavor additives contain aldehyde-like chemicals that react with peroxides in omega-3 oil, creating compounds that mimic the signature of oxidized fat, making the oil appear more degraded than it actually is.

    Flavored omega-3 supplements were found to have more signs of spoilage in tests than unflavored ones, which means the added flavors might be making the oil seem older or broken down than it really is — or actually causing it to go bad faster.
