More specialist Admiral Nurses will be able to provide support for people living with dementia thanks to the 5p carrier bag charge.
The medical staff, who work in the community, also support families of people with dementia.
The new positions will be funded across Norfolk and Suffolk from carrier bag sales by the Central England Co-op.
The supermarket, which covers 16 counties including Norfolk and Suffolk, is donating £500,000 from the 5p levy to Dementia UK.
As well funding new Admiral Nurses, the money will provide on-going training for those already working in those positions.
By 2020, the amount of people living with dementia in Norfolk and Suffolk is expected to be 17,030 and 13,746 respectively.
Martyn Cheatle, CEO of Central England Co-op, said: 'Dementia is an increasing issue in the UK, and support services are under strain.'
He added Admiral Nurses did 'vital work'.
