Can I drink 6 Monsters a day?

Anyone who's ever had one too many will recognize the point at which caffeine stops being productive and starts to make you feel slightly ill, with shaky hands and a fluttering heart. And that's definitely the case with energy drinks, too. But , and can energy drinks kill you? And if they're that dangerous, how many Red Bulls can you drink before you die? How many energy drinks is too many?

According to Healthline, can lead to dizziness, diarrhea, insomnia, fever, vomiting, trouble breathing, uncontrollable muscle movements, convulsions, and an irregular heartbeat, among other scary symptoms.

And energy drinks, like Red Bull and Monster, include a number of energizing ingredients in addition to caffeine — and, according to Mayo Clinic Health Systems, they can also contain additional caffeine sources that are actually listed simply as an "energy blend" on the label. That may sound innocent enough, but the "blend" — which typically contains ingredients like taurine, glucuronolactone, guarana, and B vitamins — can also have pretty extreme side effects, including heart attacks, according to a study published in Mayo Clinic Proceedings.

But the human body can handle a fair amount of energy drink-induced unpleasantness before it ceases to function. How much — and how many energy drinks a person can consume before they die — depends on the individual. According to Mayo Clinic, most healthy adults can safely drink up to 400 milligrams (mg) of caffeine per day, which equates to about four cups of brewed coffee or two "energy shot" drinks. While all energy drinks vary, per the Center for Science in the Public Interest, a 16 oz can of Monster contains 160 mg of caffeine, and an 8.4oz can of Red Bull contains 80 mg of caffeine.

Caffeine Informer has a special calculator to help the energy drink imbibers determine how many of the stimulating beverages they can handle before their hearts give out.

Based on their math, a person who weighs 115 pounds, for example, could withstand:

- 48.2 8 ounce cups of brewed coffee

- 101.9 1.5 ounce shots of espresso 

- 98.1 cans of regular Red Bull 

- 49.1 cans of Monster Energy Drink

- 39.2 bottles of regular 5-Hour Energy

- 1,308.1 espresso beans 

- 313.9 8 ounce cups of green tea 

- 230.8 cans of regular Coca-Cola

And so on and so forth. Combine all of these and the result is almost certain death, but each number on its own represents this hypothetical person's threshold for the energy drink in question. It could be assumed that most people would experience some sweaty, wild-eyed puking before they actually expired — if that's the case, medical attention is never a bad idea.

Shocking photos show the damage done to a teenager’s teeth as a result of what he claims to be a ‘crippling addiction’ to energy drinks.

Vinnie Pyner, 21, said he drinks six cans of Monster Energy a day and first got hooked when he relied on the drink to keep him awake while studying during college.

Soon he was downing them at breakfast, lunch and dinner, he said.

Vinnie claims he brushed his teeth twice a day but after a short time he started getting tooth pain and eventually his front fourth teeth ‘snapped’ when he bit into an apple.

After drinking around 45 cans a week for seven months, he went cold turkey – but was too embarrassed to go back to college.

His dentist discovered every tooth in his mouth had rotted and now Vinnie is now set to get 24 fillings as well as dentures.

Mortified Vinnie, of Margate, Kent, is speaking out to warn others about the dangers of excessive energy drink consumption.

He said: ‘It started as a way to relieve the stress and pressure from my college course because you have to be focused when it comes to computing and coding.

‘But I never thought that it would get this bad, it’s affected my confidence dramatically.’

He said his dentist was ‘extremely shocked to see my teeth’ and that it was ‘one of the worst cases of tooth decay and damage that he had ever seen’.

‘Looking at my teeth, I realised what I had done, I was in a complete mess,’ Vinnie said. ‘Monster Energy has completely ruined my life.’

After discovering that his upper four teeth had broken off, Vinnie said he would try not to open his mouth too wide when near his mum.

But mum Tara got suspicious after several days and asked him to show her his teeth.

Tara said: ‘It was absolutely shocking. His upper four incisor teeth had completely fallen off and you could see his gum line, it was horrible.’

Vinnie said he dropped out of college because his confidence plummeted to slow, he now spends all his time at home and rarely goes out at all.

He added: ‘I can’t do much at all, let alone think about my future.

‘I can’t apply for any jobs because interviewers will take one look at my teeth and say no straight away.

‘The smile is the first thing you see in a job interview.’

A British Dental Association spokesperson said: ‘Consuming large quantities of sugar fuels tooth decay and fizzy drinks are the largest single source of sugar for children aged 11-18.

‘The decay they are fuelling impacts on school readiness, confidence, and future employability.

‘Sweet drinks contribute to widening the oral health gap, as children from the poorest backgrounds are almost twice more likely to drink them regularly than then more well-off peers.’
