Hey guys, just curious as to how much caffeine i can consume in a day. Are there any dangers associated with taking too much caffeine? I dont want to become dependent, but lately the energy boost it gives is much needed.

"Caffeine overuse
Caffeine is a drug that in large amounts, especially over an extended period of time, can lead to a number of physical and mental conditions. The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) states: "The 4 caffeine-induced psychiatric disorders include caffeine intoxication, caffeine-induced anxiety disorder, caffeine-induced sleep disorder, and caffeine-related disorder not otherwise specified (NOS)."
A high intake of caffeine, especially over long periods of time, can lead to nervousness, irritability, anxiety, tremulousness, muscle twitching, insomnia, heart palpitations and hyperreflexia.[14] Furthermore, because caffeine increases the production of stomach acid, high usage over time can lead to peptic ulcers, erosive eso****itis, and gastroeso****eal reflux disease. [15] However, since both "regular" and decaffeinated coffees have also been shown to stimulate the gastric mucosa and increase stomach acid secretion, caffeine is probably not the only component of coffee responsible. [16]
[edit]
Caffeine intoxication
An acute overdose of caffeine, usually in excess of 250 mg (more than 2-3 cups of brewed coffee), can result in a state of central nervous system overstimulation called caffeine intoxication. The symptoms of caffeine intoxication may include restlessness, nervousness, excitement, insomnia, flushing of the face, increased urination, gastrointestinal disturbance, muscle twitching, a rambling flow of thought and speech, irregular or rapid heart beat, and psychomotor agitation. [17] In cases of much larger overdoses mania, depression, lapses in judgment, disorientation, loss of social inhibition, delusions, hallucinations and psychosis may occur.[18]
In cases of extreme overdose, death can result. The LD50 of caffeine is 192 mg/kg in rats. [19] The LD50 of caffeine is dependent on weight and individual sensitivity and estimated to be about 150 to 200 mg per kg of body mass, roughly 140 to 180 cups of coffee for an average adult taken within a limited timeframe that is dependent on half-life. Though achieving lethal dose with coffee would be exceptionally difficult with regular coffee, there have been many reported deaths from intentional overdosing on caffeine pills. [20] [21] [22] [23]
[edit]
Anxiety and sleep disorders
Long-term overuse of caffeine can elicit a number of psychiatric disturbances. Two such disorders recognised by the APA are caffeine-induced sleep disorder and caffeine-induced anxiety disorder.
In the case of caffeine-induced sleep disorder, an individual regularly ingests high doses of caffeine sufficient to induce a significant disturbance in his or her sleep, sufficiently severe to warrant clinical attention. [24]
In some individuals, the large amounts of caffeine can induce anxiety severe enough to necessitate clinical attention. This caffeine-induced anxiety disorder can take many forms, from generalized anxiety, to panic attacks, obsessive-compulsive symptoms, or even phobic symptoms. [25] Because this condition can mimic organic mental disorders, such as panic disorder, generalized anxiety disorder, bipolar disorder, or even schizophrenia, a growing number of medical professionals believe caffeine-intoxicated people are routinely misdiagnosed and unnecessarily medicated. Shannon et al (1998) point out that: [26]"

600 a day is about right
that other big post ? ha theres 100mg in ONE cup of coffee. thats bogus
now if u take 600 a day for a month, you will prob develop dependency. i take about 100-300 a day for about 2 or 3 weeks, then avoid it all together for a week (just try to get more sleep) that way i never get addicted to it and i can still operate on or off from it.
if you wnat to avoid caff for stimulation or switch it up, ive heard good things about L-tyrosine for givin a kick

does anyone know an estimation of caffeine content per mass of coffee? All the sites I can find quote caffeine per "cup" which is totally useless.
My experiences with caffeine anyway are that "six cups" (6 x the recommended amount) of instant coffee gave me a very noticeable effect and a happy day. The next day, 1.5 times that dose left me cold, shaking, weak, and feeling pretty crap. Try it yourself and find what makes you happy5'11", 187lbs, 19 y/o

"A standard cup of coffee contains 70-180mg caffeine depending on the strength and method of preparation. Usually it will be around 75-80mgs unless you make your coffee extremely strong."
from medline.com
"It's usually presumed that a regular cup of coffee contains 100mg of caffeine but it may range between 40 and 176 mg and the mean is closer to 85mg. The typical american usually takes in about 70-80mgs per cup of coffee."
"How much caffeine is present in a cup of coffee ?
Drip - 50-175mg (average around 75mg)
Espresso - 100mg per serving
Brewed - 80-135mg
Instant - 65-100mg"

Be very careful when taking caffeine in large quantities for extended periods of time. As an example of what can happen my father used to consume excessive amounts of coffee (probably 600-1000mg of caffeine a day) and developed heart palpitations (irregular heartbeats). They stopped when he eliminated caffeine from his diet.
Why would you want to consume such high amounts anyway?

Lots of Caffeine = ok
I take 600-1000mg of caffeine (from 200mg pills and occasionally some espresso) every day, and am, admittedly, currently dependent on it.
That amount is fine from time to time, but every day is taking a toll on me. I'm just a highschool student at a competitive Boston-area school trying to make it through exams.
To note, from time to time, I've taken 1,400-1,600 in a single day. That's really a lot, but still just fine if you're used to it.
Don't freak out over 200-600mg; that's really nothing.

Strong bump on this thread ><
:P
You the worst of us all! mr like 2g a day lulz
That article looks very badly done
Your typical cup of coffee being sold by Starbucks has far more caffeine than they claim to start with, and most are not buying/drinking 1 single small 4-6 ounce cups of coffee /soda etc and this is not new this has been going on for many decades. Their age group is showing 200mg.... avgs like that is laughable given the amount of sales in coffee and energy drinks not to mention soda consumption alone which by it self makes that chart laughable a coke or pepsi/soda in general might be fairly low on caffeine ( 30mg-60mg ) per 8-12 ounces but the amount your avg soda drinker is consuming puts it well beyond that chart.
A single cup of coffee can have well over 500mg of caffeine FYI
IMO people have not a single clue how much they drink ( your avg person unlikely tallies all consumed beverages over time ) or how much caffeine they actually ingest. What they base their chart on > http://www.sciencedirect.com/science...78691513007175 which is using as they say several generic sources but cups of coffee even within the same location can wildly ( 200mg - 500mg+ within the same size at the same location on the same day ) vary on the caffeine content not to mention nobody there is measuring exact ounces people order small/med/large not 6/10/24 ounces etc at many places lot of places even offer free refills did I drink 2? maybe I had 3? was it 12 I dunno could been 10 ounces nothing at all to account for what's actually being consumed or what's in it.Last edited by Rob1882; 04-30-2016 at 06:11 AM.

I would think that everyone has a different limit depending on body size and tolerance to caffeine. Personally I've gone away from extreme stims. But I think it's more of a trial and error thing start low and work your way up if that's the route you want to take.

A single cup of coffee does not have over 500mg of caff. A Starbucks venti ( 20oz not 8 ) has only 415. And Starbucks is on the higher side for commercially consumed coffee.
A typical cup has around 90-150.Your nutrition and workout program determines your success.

What is a typical cup? and who is buying a 6-8 ounce cup when every store/shop in PA, OH I have been in sells up and offers free refills which is not at all discussing the amounts in said cup.
http://www.brinkzone.com/articles/wh...bout-caffeine/
Which had some links to actually testing cups showing how off they can be
Caffeine Content of Coffee
As the previous section outlines, if you want to enjoy your cup of coffee because it tastes good, and gives you a coffee buzz – that’s likely due to a variety of naturally occurring compounds in the coffee in addition to the caffeine – go for it. I won’t be giving up my mug of strong morning coffee either. However, if you are looking specifically to get the known effects of caffeine on performance, increased alertness, etc., use straight caffeine.
Even if you are attempting to drink coffee for its caffeine content, that’s a hit or miss strategy. Researchers visited a variety of specialty coffee store for 6 consecutive days and tested a wide range of coffees and found the caffeine content varied considerably (3). According to these researchers:
“There was a wide range in caffeine content present in caffeinated coffees ranging from 58 to 259 mg/dose. The mean (SD) caffeine content of the brewed specialty coffees was 188 (36) mg for a 16-oz cup. Another notable find is the wide range of caffeine concentrations (259-564 mg/dose) in the same coffee beverage obtained from the same outlet on six consecutive days.”
So the same cup of coffee purchased from the same vendor (Starbucks) over six consecutive days ranged from 259 to 564 mg of caffeine!!! That’s like power gulping 3.2 to just over 7 small cans of Red Bull®—over 15-30 minutes (see below). If you want to try and experiment to confirm what the earlier mentioned study found regarding the different effects coffee has from straight caffeine, try 600mg of pure caffeine some time. Your head may explode, but you will never doubt again what an equal amount of caffeine feels like that can be found in a really strong cup of coffee.
Edit: you should also read better I didn't give a direct size only said cup not even "typical" u just wanna argue to argue and get picky over words here.. bottom line 200mg of caffeine isn't **** and your avg coffee drinker is likely consuming massively over that website's claims.
Also put some bold and colors on that so you can suck that dry :P their listed avg's don't mean **** when even the same pot can vary between cups; So does this make us all drug addicts? that is a joke haha Clearly Coke & Pepsi seem to think it boosts sales tho.Last edited by Rob1882; 04-30-2016 at 07:01 AM.

I can read fine. A cup by the way is 8oz. Two cups is 16. 3 cups is 24. You said a single cup is well over 500. That study as well was down with 16oz noted which is two cups not a single cup.
Just helping you with your accuracy Rob so don't get mad, still love ya donut queen.Your nutrition and workout program determines your success.
