Dairy products with reduced electrolytes, such as milk products with reduced electrolytes, are provided that contain potassium at less than 70 mg/100 g. Production involves subjecting a starting milk composition to ultrafiltration (UF) to provide a UF retentate and a UF permeate. The UF permeate, containing a high monovalent ion, multivalent ion and lactose content, is pH-adjusted to at least about 7.0. The pH-adjusted UF permeate is subjected to nanofiltration (NF) to provide a NF retentate with a reduced monovalent ion content. One or more NF cycles may be performed. The UF retentate and the NF retentate are combined to provide a dairy product with a reduced monovalent ion content that contains a substantial portion of solids, lactose, and divalent and multivalent ions from the starting milk product.
