Soybean oil is a clear yellowish vegetable oil extracted from soybeans. Soybean oil is not an E number excipient but a food, although in the dietary context it also functions as an excipient. Soybean oil is used both as a cooking oil and by Pharma Nord as a filler in some preparations.
Soybean oil is high in polyunsaturated fatty acids and low in saturated fatty acids. Soybeans also contain proteins to which some people are hypersensitive. Some of these proteins are also oestrogens. They are also called phytoestrogens or plant oestrogens. They are found in small amounts in all fruits and vegetables. The soya plant has the highest content of phytoestrogens.
The soybean oil used by Pharma Nord has little in common with the soybean oil that can be bought for cooking.
Pharma Nord uses a mix of different GMO-free soy oils of pharmaceutical quality and of different viscosity, which means a mixture of more or less viscous oils. These oils are completely purified from soy protein substances, including oestrogens and oestrogen-like substances. The oil is subjected to a control analysis in an external laboratory. Therefore we do not need to allergy label our soybean oil.
There is a negligible amount of trans fatty acid in the soybean oil. This is because we have to hydrogenate a fraction of the soybean oil to achieve the consistency needed for optimal absorption of the Q10 content. To put this into perspective, a glass of milk contains 15 times as much trans fat as 1 capsule of soy oil-based Bio-Quinone.
