The invention discloses a method for synthesizing guanidinoacetic acid and its salts. The guanidinoacetate synthesis method comprises the following steps: 1) neutralization reaction of guanidine hydrochloride with alkaline substance C to obtain solution A; 2) reaction of chloroacetic acid with an alkaline solution to obtain solution B; 3) solution A and solution B Reaction, generate guanidine acetate. The basic substance C may be sodium hydroxide or sodium carbonate. The preferred mass ratio of sodium hydroxide: guanidine hydrochloride: chloroacetic acid is 200: 480: 460. The sodium carbonate: guanidine hydrochloride: chloroacetic acid
