The present disclosure relates to granules comprising an L-amino acid and a method for preparing the same. The method may comprise: (a) preparing a fermentation liquid of L-amino acid; (b) removing moisture from the fermentation liquid of L-amino acid such that the solid content of the fermentation liquid of L-amino acid is in a range of 20% to 90%; (c) forming granulated particles with a moisture content of 0% to 40% by mixing the concentrated fermentation liquid of L-amino acid with a seed; (d) drying the granulated particles formed in Step (c); (e) sieving the granulated particles dried in Step (d); and (f) pulverizing or circulating the particles left in step (e) to be recycled as the seed in step (c).
