PROBLEM TO BE SOLVED: To provide a process for producing nano-fibrillar cellulose gels， which is not only easily carried out， but energy efficient. SOLUTION: There is provided a process for producing nano-fibrillar cellulose gels including the steps of: (a) providing cellulose fibers， in which all or a part of this cellulose fibre may be issued from a step of recycling a material comprising cellulose fibres; (b) providing at least one filler and/or pigment; (c) combining the cellulose fibers and the at least one filler and/or pigment; (d) fibrillating the cellulose fibers in the presence of the at least one filler and/or pigment until nano-fibrillar cellulose gels are formed. The decrease in viscosity of the mixture after stepwise increase of a shearing rate is higher than a corresponding increase in viscosity after subsequently stepwise reduction of a shearing rate over at least a part of the range of the shearing rate.
