The invention relates to stabilizer compositions for polymers such as polyolefin polymers. The stabilizer compositions include an antacid, an organic acid- metal salt, and a primary oxidant such as a sterically-hindered phenolic compound, a sterically-hindered amine compound, a hydroxylamine compound, and combinations thereof. The invention also relates to a method for the preparation of the stabilized polymer compositions provided by the use thereof.
