Midway through the half, the hosts took the lead thanks to Yohan Cabaye's surging run into the Liverpool half unchallenged, before unleashing a looping shot which keeper Simon Mignolet couldn't deal with.
The visitors struggled to get a foothold in the game as the Magpies looked the more likely to score.
However, just before half time Suarez found himself bearing down on goal only for Mapou Yanga-Mbiwa to pull him down.
Liverpool started the game level on points with Arsenal at the top of the table.
