How much caffeine is in a 5-hour Energy?

How much caffeine is in a 5-hour Energy shot?

5-hour Energy’s current Berry labels give 200 mg of caffeine in a Regular Strength shot and 230 mg in an Extra Strength shot, each a serving of 1.93 fl oz, the whole bottle. The caffeine is printed in brackets inside an “Energy Blend” of 1,870 mg (regular) or 2,000 mg (extra strength). The product pages call it a “2-ounce bottle”. 402403171

So the famous number is right, as long as you know which bottle. Regular is 200 mg, Extra Strength is 230 mg, and the bottle is the same 1.93 fl oz either way: the product pages round it up to a “2-ounce bottle”, the label does not. The caffeine is not on a line of its own. It sits in brackets inside an “Energy Blend” of 1,870 mg or 2,000 mg, between L-phenylalanine and citicoline, which is a strange place to keep the main ingredient.

The maker’s own pages do not always agree with the label. On the day we read it, the Regular Strength page got its own headline number wrong, in a row of icons above its Supplement Facts.

On November 12, 2026, the Regular Strength Berry product page said “230mg of Caffeine / The same amount in a 8 oz cup of coffee” in its icon row, while the Supplement Facts panel on the same page said “Caffeine (200mg)”. The 230 mg is the Extra Strength figure. 402

The label is the thing on the bottle, so trust the 200 mg. If you are counting your day, the drinks page has the cans and cups to count it against.

Is 5-hour Energy stronger than Red Bull or Monster?

Per container, a little: 200 mg against 160 mg in a 16 fl oz Monster and 151 mg in a 16 fl oz Red Bull. Per fluid ounce, it is not close. A regular shot is 103.6 mg per fl oz; Monster is 10 mg per fl oz and Red Bull 9.5 mg per fl oz. By our arithmetic that makes the shot 10.4 times as strong as Monster and 10.9 times as strong as Red Bull, and Extra Strength 12.5 times as strong as Red Bull.

Even the strongest cans in our energy-can table, Bang and the rivals that tie it at 300 mg, are 18.8 mg per fl oz, which leaves the regular shot 5.5 times as strong. That is why a chart that ranks shots and cans on one scale is no use: the cans become a row of crumbs. The full ranking of cans is in which energy drink has the most caffeine, and Celsius has its own page.

A 5-hour Energy is a Red Bull with the water wrung out. I respect the efficiency and fear it

Is a 5-hour Energy the same as a cup of coffee?

The maker says so, in three different ways.

5-hour Energy’s FAQ says a Regular Strength shot contains “about as much caffeine as 8 ounces of the leading premium coffee”, and Extra Strength about as much as “12 ounces of the leading premium coffee”. Its caffeine page puts the regular figure as “8 ounces of the leading premium coffee, or 200 mg”. The footer on its product pages says regular is “comparable to a cup of the leading premium coffee”. None of these pages names the coffee. 404171402

Do the division and the two comparisons describe two different coffees. Eight ounces holding 200 mg is 25 mg per fl oz; twelve ounces holding 230 mg is 19.2 mg per fl oz. USDA’s brewed coffee, the plain cup in our coffee article, is 11.8 mg per fl oz, so 8 fl oz of it holds about 95 mg. The maker’s regular comparison needs coffee 2.1 times USDA’s strength. The coffee is never named, so there is nothing to check it against.

Strong coffee exists: Starbucks states 315 mg to 390 mg for a grande brewed coffee. But a plain 8 fl oz mug at USDA’s strength is about half a regular shot. The label used to be vaguer still.

In NIH’s Dietary Supplement Label Database, a 5-hour Energy Berry label entered on October 26, 2011 gives a 2 fl oz serving, lists caffeine with no amount and says “Contains about as much caffeine as a cup of coffee.” A Berry label entered on August 23, 2019 lists 200 mg of caffeine in a 1.93 fl oz bottle. The database does not say when the label changed. The 2019 record’s label carries a ©2015 notice and the version code ZS0004-US (01/15/15). 409410

So the older label compared itself to a cup of coffee without printing how much caffeine it held. By the label entered in 2019 the milligrams were there, and the coffee comparison had stayed, now as “a cup of the leading premium coffee”.

Does decaf 5-hour Energy have caffeine?

It did, and the maker no longer sells it on its own store. Decaf was real, it was sold to people sensitive to caffeine, and it was not caffeine-free.

A Decaf 5-hour Energy label in NIH’s Dietary Supplement Label Database (Decaf Citrus, entered May 22, 2015) says “Decaf 5-hour ENERGY(R) contains 6mg of caffeine - about as much as a half cup of decaffeinated coffee.”, in a 1.93 fl oz serving, “For people sensitive to caffeine”. On November 12, 2026 no decaf product was on the maker’s online store or its list of discontinued products. 408407

By our arithmetic that is 3.1 mg per fl oz, against 103.6 mg per fl oz for the regular shot. The trouble was what it promised. Washington State sued the makers, and the court looked hard at Decaf.

In a suit Washington’s Attorney General filed in 2014, a King County Superior Court judge ruled in October 2016 that the makers of 5-hour Energy had broken the state Consumer Protection Act. She found that none of the studies they submitted supported the claim that the other ingredients make caffeine’s effects last longer than caffeine alone, and that the claim that Decaf gave similar effects lacked “competent and reliable scientific evidence”. She also found evidence that the non-caffeine ingredients may themselves support energy and alertness, and that the “no crash” claim did not break the Act. In February 2017 she ordered the makers to pay nearly $4.3 million in penalties, fees and costs, nearly $2.2 million of it civil penalties. 412413

Read that ruling precisely. The judge did not find the shot useless: she found evidence that its other ingredients may support energy and alertness, and she cleared the “no crash” claim. Among what she found deceptive: the claim that the blend makes caffeine last longer than caffeine alone, the claim that Decaf did what the caffeinated shot does, and the claim that doctors recommend it. If you want a low-caffeine drink, decaf coffee is easier to find.

Is 5-hour Energy FDA approved, and is it bad for you?

5-hour Energy is sold as a dietary supplement, with a Supplement Facts panel rather than Nutrition Facts. The maker’s FAQ answers “Have 5-hour ENERGY® shots been approved by the FDA?” with “No, they haven’t. Dietary supplements like 5-hour ENERGY® shots don’t need to be approved by the FDA.” The label says “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.” 405404402

That status matters. A supplement’s maker, packer or distributor must pass on to FDA the reports of serious adverse events it receives; FDA’s document below says that duty “applies only to dietary supplements and not to beverages”. In 2012 FDA published a summary of the reports in its system for three energy brands.

FDA’s 2012 document on adverse event reports for 5-Hour Energy, Monster and Rockstar, from January 1, 2004 to October 23, 2012, has a table of reports “Allegedly Related to 5 Hour Energy”. By our count of its rows there are 92 reports; the outcomes of 33 include hospitalization and of 13 include death. FDA writes that the reports “only reflect information AS REPORTED and do not represent any conclusion by FDA about whether the product actually caused the adverse events.” 411

Say it plainly: 13 reports with death among the outcomes prove nothing about what caused those deaths. A report records what someone told FDA; it is not a finding that the shot caused anything, and FDA’s own document says so in the words above. It also notes that people may have taken other products, and that reports can be duplicated or incomplete.

What is settled is the caffeine. One regular shot is 200 mg, exactly the 200 mg single dose that EFSA says raises no safety concern for healthy non-pregnant adults. Extra Strength is above it. How long caffeine stays in your system explains why the dose keeps going after the shot is gone, and when a dose counts as a lot sets the shot against every agency’s line.

Legally it’s a dietary supplement, which is also how I file my third coffee

How many 5-hour Energy shots can you have in a day?

The label sets its own limit, and the sums are worth doing.

The label says “Do not exceed two bottles daily, consumed several hours apart.” Two 200 mg Regular Strength shots are 400 mg, the daily amount EFSA and FDA cite for healthy adults; two 230 mg Extra Strength shots are 460 mg, 60 mg over it. The label’s “one half (1/2) bottle” is 100 mg of regular or 115 mg of extra strength. The gummies’ limit of 20 a day, at 92 mg per 4, is also 460 mg. These sums are ours. 402403406225

EFSA concludes that caffeine intakes up to 400 mg a day from all sources, spread through the day, do not raise safety concerns for healthy adults, except pregnant women. FDA cites 400 mg a day for most adults as an amount not generally associated with negative effects, and notes wide variation in how sensitive people are to caffeine and how fast they eliminate it. 225

So two regular shots land exactly on the line with nothing else counted, and two Extra Strength shots are 60 mg over it, inside the maker’s own limit. The half bottle the label suggests is 100 mg of regular, a little more than our 80 mg cup of filter coffee. Neither line is a cliff, and people differ a lot in how fast they clear caffeine: its half-life in healthy adults averages 4 hours and runs as long as 8 hours.

The label says no more than two bottles a day, several hours apart. I read that as a schedule
