DOES IT WORK?
Soybean oil is one of the cheapest and most common softgel filler oils. It dissolves fat-soluble ingredients and helps with absorption. Contains omega-6 fatty acids (linoleic acid), but most people already get too much omega-6 from their diet. It's a functional excipient, not a health ingredient.
