In this article, equine nutritionist Karen Richardson reviews the scientific research available to find out if the claims made by supplements based on pectin-lecithin complexes match their effectiveness in preventing and treating equine gastric ulcer syndrome (EGUS).
Understanding phospholipids’ protective role
Back in 1983, a group of researchers discovered the mucosal lining and the gastric juice of dogs contained a group of surface-active phospholipids. Phospholipids are made up of two fatty acids (long chains of hydrogen and carbon molecules), which are attached to a glycerol ‘head’. The glycerol head region of the molecule is hydrophillic (attracts water), while the fatty acid tail is hydrophobic (repels water).
