Malcolm Turnbull probably could have done with some vitamins during the eight-week fight to the election finish line.
Now recovered from his bout of prime ministerial flu - and with just a day to go until polling day - he's visited a robotic processing plant packing krill oil.
"Isn't that phenomenal," he said as he watched the machine build, pack and seal boxes full of tablet bottles with wife Lucy and Defence Minister Marise Payne on Friday.
After a string of radio and television interviews he used a visit to Robotic Automation in the marginal Liberal-held inner-western Sydney seat of Reid to talk up his favourite topic.
"I love innovation," he said, beaming to a wall of cameras.

Standing on a pallet on the warehouse floor surrounded by young Liberal faithful, Mr Turnbull stuck to his script.
"The truth is that we do live in the most exciting times in human history," he began.
Mr Turnbull stressed technology, such as that he had just seen, can be exported around the world and is why his government is pursuing its economic plan.
He again called for voters to back stability and stay clear of independents when they cast their ballots.
"Tomorrow I ask every Australian to treat their vote, for the house and for the Senate, as though they are the votes which determine the future of our government," he said.
Craig Laundy, who holds the seat with a 3.3 per cent margin, said the coalition needs to finish the last 24 hours of the campaign as strongly as it started.
"Why? Because this is the most important election that I've seen in my lifetime," he said.
"I'm a little bit older than you guys but I reckon it's going to be the most important in yours too."
Mr Turnbull left after receiving a warm applause from supporters but refused to take questions from the travelling media.
