Staying hydrated: Justin Bieber, 25, cycled around Beverly Hills on Friday with a portable IV drip inserted in his arm

Justin was dressed with safety in mind with his maroon helmet, which matched his Crocs, which were adorned with colorful pins.

He kept his look simple wearing a plain white tank top and a pair of white athletic shorts with green and blue text.

He was pedaling leisurely on his black bike, which featured prominent thick tires.

Justin’s chipper attitude appeared to be absent during the bike ride, and he appeared stone-faced as he charged through the city.

Safety first: Justin was dressed with safety in mind with his maroon helmet, and he had on a white tank top that highlighted his many tattoos

Justin’s left wrist was wrapped in a thick hot pink bandage that held an IV inserted into his vein.

The tubing was connected to a black bag slung around Justin’ shoulder that contained the IV bag.

Previously, the Sorry singer has reportedly gotten vitamin drips that are intended to boost energy, cure hangovers and assist with other common maladies.

However, the science behind the IV drips is largely absent, and medical professionals have harshly criticized the practice, popular among celebrities, as a snake oil treatment.

‘The whole thing is really nonsense,’ Dr. Stanley Goldfarb, professor of medicine at the University of Pennsylvania Perelman School of Medicine, told WebMD in 2018.

‘It’s just catering to people’s sense that they’re taking their health into their own hands.’

Questionable: Non-essential vitamin IVs are now trendy among wealthy clients and are advertised as a means to cure hangovers, boost energy and keep one’s immune system healthy

CBS News chief medical correspondent Dr. Jon LaPook was similarly unimpressed back in 2015.

‘None of those [health claims] have been FDA approved or validated by any kind of controlled scientific studies,’ he said in a story on the phenomenon.

‘In fact, there’s something here that specifically says, “This product is not intended to diagnose, treat cure or prevent any disease. This service is intended only for healthy adults.” Well if you’re a healthy adult, why do you need this?’

Although most celebrities who try these casual IV drips are in perfect health (aside from a possible hangover), they can actually cause more problems than they fix.

Last year, Kendall Jenner was hospitalized after getting a vitamin IV drip.

The details of her condition were kept quiet, but unnecessary IVs raise a patient’s risk of infection.

The bags may also be pumping excess vitamins that aren’t needed and will be quickly evacuated from the body.

Minuses: IVs like Justin’s have been called ‘snake oil’ by medical professionals, and none of their medical claims are FDA validated or approved. The bags also raise one’s risk of infection

Justin may have been trying to ward off a hangover with his IV on-the-go.

The Where Are Ü Now singer spent the previous evening handing out snow cones to trick-or-treaters with his wife Hailey Bieber.

Later in the evening she ditched him to attend Kendall Jenner’s birthday party, where she dressed up as Lola Bunny from Space Jam, sans the ears.

Justin rocked a low-key outfit of his own Drew brand clothing with a Drew hockey goalie mask inspired by Jason from the Friday The 13th series of horror films.

Though he finds plenty of time to relax, the singer has been keeping busy in the studio.

Earlier this week he posted on Instagram that he would release his newest album before Christmas if his post got 20 million likes.
