Germany releases safety analysis report on dietary supplements containing algae oil

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.

Among the 30 samples analyzed, the DHA and EPA content was normal, but the DHA/EPA ratio fluctuated greatly. Algae oil contains a considerable amount of cholesterol, ranging from 504 to 4490 mg/kg, which is comparable to some fish oil products. Some samples have significant content of fatty acid ethyl esters (Fettsäure-Ethylester), which may be related to the addition of ethanol during the algae fermentation process. The peroxide values of some samples exceeded the prescribed standards, indicating possible oxidation problems. Most samples contained antioxidants, but some samples were not labeled as required. The inspection also found that 11 ...
