The invention provides an equal evaluation method of phagocytable ability of probiotics, which is a relatively correct evaluation method of phagocytable ability of probiotics in the cell level, and meanwhile can readily perform the evaluation under a state relatively similar to an in vivo state without any method with a huge burden like the surgical operation. The invention is an evaluation method of phagocytable ability of probiotics, which includes contacting the probiotics with a cell, wherein the cell has not in contact with a bacterium and has a phagocytic ability.本發明提供一種均等的生菌劑的被吞噬能力的評估方法，其是在細胞層級中較為正確的生菌劑的被吞噬能力評估方法，同時能以無須負擔龐大的外科手術等的方法來簡易地在較接近生物體內狀態下進行評估。本發明是一種生菌劑的被吞噬能力的評估方法，其包含使生菌劑接觸細胞之步驟，該細胞未曾接觸細菌並具有吞噬作用。
