Dakota Johnson Admits She Didn’t Know Celsius Was an Energy Drink: ‘I Thought It Was Just Vitamins’

“I didn’t realize that I was basically overdosing on caffeine,” said the director of ‘Loser Baby’

Dakota Johnson knows all about Celsius thanks to her new short film!

The Madame Web star, 34, shared in an interview with Variety on Saturday, Sept. 7, that she recently figured out Celsius is an energy drink after consuming plenty of it on the set, as director, of her short film Loser Baby.

“I discovered Celsius on [the first day] of filming the short and I didn’t know that it was Red Bull,” Johnson admitted to the outlet.

The director explained she “thought it was just vitamins” and considered it a “natural drink” because the drink noted it had “B12 and vitamin A.”

“I was like, ‘I'm so inspired. I'm awake all night long… I’m not sleeping because I’m just thinking about'— and it was because I was having like two Celsius a day,” she said.

“I didn't realize that I was basically overdosing on caffeine,” she added.

Most Celsius flavors contain 200 milligrams of caffeine per can, while other variations contain up to 270 milligrams of caffeine per can.

She said the costume designer on set eventually was the one who alerted her about the drinks, telling her, “You're basically having four Red Bulls a day.”

When asked if it was “upsetting” when she found out, Johnson said with a laugh, “That was really upsetting. Yeah, it was. But now I know that in dire straits, there’s Celsius. And I’m looking for an endorsement, [because] I’m your girl. Night shoots, they work really well.”
