An inspection of 30 samples of algae oil revealed significant variations in the DHA/EPA ratio, with normal DHA and EPA content but high cholesterol levels ranging from 504 to 4490 mg/kg, similar to some fish oil products. The analysis also identified fatty acid ethyl esters, potentially indicating ethanol addition during fermentation, and excess peroxide values, suggesting oxidation. The majority of samples contained antioxidants, but some were missing required labels. Eleven samples were found to violate regulations on health claims, particularly concerning DHA and EPA's impact on cholesterol levels.
