While the connections between caffeine intake and performance benefits are clear, those gains could come with a significant side effect: A new study published in Medicine & Science in Sports & Exercise found using caffeine before or during a workout could increase the risk of blood clots. While consuming caffeine before a workout can be beneficial in enhancing performance, consuming too much caffeine can lead to some negative side-effects. Some of these side-effects include restlessness, insomnia, rapid or abnormal heart rhythm, anxiety, upset stomach or heartburn, and increased blood pressure.

They recommend that people use caution when using caffeine before a workout. Too much may produce side effects like jitteriness, heart palpitations, and sleep disturbances. “It can reduce pain,”. A 2006 study suggests that drinking coffee just before a workout might not be the best idea.The Journal of the American College of Cardiology reports that the amount of caffeine in just two cups of coffee limits the body’s ability to increase blood flow to the heart during exercise. This is problematic since blood flow to the heart must increase during exercise in. Dangers.

Written by Grey Evans. 12 July, 2011. Fact Checked. Caffeine, a psychomotor stimulant found in many beverages, is present in many pre-workout stimulants.

Used on its own, caffeine acts to increase the activity of your central nervous system, and this increase may lead to an increase in performance. According to the 2015-2020 Dietary Guidelines for Americans, adults should limit their caffeine consumption to no more than 400 milligrams per day. Any more than that could cause side effects like insomnia, anxiety, fast heart rate, upset stomach and headaches.

5. Caffeine may give you diarrhea if exercise already causes you to have loose BMs. Some people also have nausea (upset stomach) or indigestion (sour stomach) if they take too much caffeine before hard exercise. You must figure out what amount of caffeine is right for you and take it at the right time before exercising. The amount of caffeine you should take before a workout to increase your performance depends on a couple of different factors, including the kind of exercise that you will be doing..

If you are. So taking it with caffeine might increase the adverse effects of caffeine, such as nausea and heart palpitations. Caffeine is a drug – withdrawal from caffeine can present side effects such as headaches, anxiety and cravings.

These can be prevented by gradually weaning yourself of.

Because caffeine occupies adenosine receptor sites, and adenosine relaxes muscles so they may return to and maintain their resting length, consistent caffeine intake can lead to muscle strain, tears and contractions, causing and retarding healing of injuries.

  • Hi Raghav,

    Can I drink Tea…before or after the workout…I do have this habit of drinking a cup of tea after coming from Gym…but only after 10-15 minutes after I come from Gym…..and in-between those 10-15 minutes I drink around a 1/2 to 1 litre of water…

    Is this habit correct…or should I change it??

  • Holy hell! I’m already hitting the maximum recommended daily dose before clock strikes two digits! I usually take 2 caffeine pills containing 200mg a pop to start off the day, then depending on how sleepy I feel, another 2 maybe around 5, and quite regularly too. That said I have a pretty high resistance to any sort of foreign substances, for better and worse; no wonder my cousin felt like he could see sound after taking just two of those.

  • Maine 3 month se coffee nahi pi thi mujha lata tha ki coffee pine se fat hota hai ����������ab pata chala ki it’s good for weight loss ����������������������������������������������������������������������

  • Well 400 mg is quite good actually. I thought I have been surpassing the limit but guess what I’ve got about 100 mg more free to drink if I wanted to.

  • bhai aakhe khol d aap ne main order karne hi wala thaaa but aab nahi rest luga or body ko caffine ki aadat nai daaluga…..thanks bhai

  • Tooo good sir boht hi achi baatein btayi apne sahi me logo ko aadat hogyi hai ye sb ki unko lgta hai k unke bina unse gym ni jaya jayega work out ni kr skte but kab tak????

  • Pre workouts r not to b taken on a regular basis… Only on days when u r goin for a heavy n hardcore sessions!!! The idea is to use it not to abuse it!!! As simple as it gets

  • So, I’m a teenager (12-18 years)(I don’t wanna give my age online, thank you very much) and I just drank 4 Starbucks Mocha Frappuccino bottles (which is about 75mg a bottle) which is roughly 300mg in total, and I weight about 108 pounds. I know 400mg is the limit for adults, but what about for teenagers? Is this too much?

  • I am wondering if there are different kinds of caffeine? I drink a ton of coffee. It is delicious and does not really effect me. In addition, I have often had 32 oz or more of coffee plus 3-4 big energy drinks and have felt fine. (No sugar in anything though). However, one single cup of black or green tea makes me sick. I will get nauseous and jittery. I can’t drink tea at all. The opposite is what is usually reported. I do not understand why.

  • Caffeine ( goods and bads )
    1. Helps in better neuro transmission, controlling sleep
    2. Relax mind by controlling stress hormones, cortisol etc..
    3. Detoxifies liver
    Etc..
    Side effects (excess amount)
    1. Dopamine amount will be reduced, making you feel anxiety, etc..
    2. Can cause high blood pressure
    3. Pregnant woman and breast feeding woman must not use it, it will pass through placenta into baby CAN cause harm.

  • How to caffeine tablet in morning
    As I drink milk + sth every morning

    Or after some time

  • Alcohol can kill you cigarettes can kill you drugs can kill you steroids can kill you and pre workouts can kill you…. Being an idiot and taking something without reading the label ingredients and not actually being used to the stimulants can give you a bad time…. Be smart about what you take and how much you take know your limits at everything you do and if you are afraid in the first place… DON’T FUCKING TAKE IT it’s that simple Jesus

  • you also have to take into account the kids height and body weight when talking about the amount of caffeine that could be lethal to a person. If that kid was relatively short and didn’t have a lot of muscle on him or fat or any sort of body weight in general he could have died from it because of his size.

  • I was taking that Arnold prework out back in 2015 when I 1st got into bodybuilding weeks later I had an attack my heart rate speed up so fast my body began shaking it felt like an heart attack but doctors said it was a anxiety attack but omg it hurt so bad scared me my wife n kids 2019 just getting over anxiety attacks and palpitations. To be honest I’m a athlete wit great genetics within a year of training folks thought I was in gear but I had no clue about them until I did my 1st competition and did great top5 in the npc and I was the only one natural after that I was approached and tried on what to take how to get it testosterone was the start and fuck I gained 15lbs in 4wks of muscle I stopped year later stepped it up test n decca the last time I took gear was almost 2yrs ago and it’s 2019 and I’ve been out the gym for a year and you couldn’t tell I’ve been out that long I’m a truck driver and I do push-ups to maintain I plan on getting back on stage must get money up for competitions and training moral to this thoughts on staying natural and competing in that or get back on the gear and get that Arnold classic invite and I get blood work every month Ive had no problem with anything thing since I stopped taking preworkout hell I even tried a little tren and I was fine no heart problems at all.

  • There are A lot of facts in this video! A lot of them i agree with! But the thing is that jack3D has DMAA in it, and that is a totally different story. If you want to know what DMAA is, look it up and you’ll know what i’m talking about.

  • I knew I was drinking too much when they turned off the option for a double shot at the coffee machine at work, now have to stand there hitting the button over and over till I have a mighty mug full of espresso ��

  • I use to consume pre workout almost everyday and I must say pre workouts are very addictive. I was not able to workout without them but over a period of time I realised that I have stopped getting that rush even after counsuming pre workouts. This was due to my long use of these pre workouts. I do take them anymore but I still sometimes crave for them and once in a while I enjoy drinking Monster or Redbull. I must say people should refrain consuming these pre workouts and energy drinks since these are very addictive and it stops working on you over a long period of time which then push you towards higher dosage of caffiene which may be life threatning.

  • A lot of people consume gaanja (cannabis) to reduce daily life stress. Stress is not good for body and goals yet in daily iife its there.

  • i took 1600 worth and went through a feel good stage, depressed to where i was dieing stage, crackhead stage, and the worst 1, schizophrenia,i swear i was hearing voices

  • 2 days ago I drank 580mg of caffine (I didnt know it was that much) and my hands were shakeing I wanted to move all the time and my hearth rate was really high when I was just standing:D and I. WAS. RUNNING. FAAAST. and I didnt fell any need to stop + (I think I laughed more)

  • Thanks, i was wondering about my energy drink consumption. I know they’re super unhealthy and basically heart disease in a can… but hey

  • For a skinny 15 year old is 2 redbulls and 1 mount dew too much? I quaqluated how much is in all together it was 215 mg is that too much?

  • Bhai log agar aap hard intense workout karte ho or only 1 scoop lete ho then it’s not harmful
    Yes life style sahi hona jaruri hai excess using of mobile, coffee, soft drinks
    To fir to hormonal imbalance bhi hona hi hai

  • sir I am 200m athlete and I want to know that can I take caffeine or not if I can take than at which time I will take it. I am doing athletic for last 2 years

  • I usually have 10 ounce cup of coffee black medium roast every morning and then I have either another 10 ounce cup before the gym or a heaping scoop of pre-workout which is around 200mg of caffeine

  • Hey PictureFit, love your videos! I’ve been wondering if caffeine quality makes much of a difference in our bodies. Like the caffeine in coffee vs. the caffeine in a cheap Walmart energy mix for example. Thanks!

  • Ur clips has a good content…. like it ����……hope u’ll make some more videos to knew many things which others didn’t knew……..keep rocking ��…..love you bro “ guru mann”…….

  • I believe the pre-workout mentioned is JYM brand. I saw it at GNC. It has a killer 530+ mg of caffeine. That’s extreme even for people who want to lose weight. Another killer was (at the time, at least) was Stacker 2. Contains Ephedra. That stuff should have a picture of a skull & crossbones on the package. Ephedra is even worse than any pre-workout on the market.

  • One time I had 2 monsters and 2 kickstarts in an hour and let me tell you that was an experience. The world was quiet and zoomed in and then I passed out a little while later.

  • Due to medico-legal concerns and the sheer number of questions I receive from these videos, I can no longer answer questions left in the comments. If you have a medical issue and would like more information, go to https://www.drdavidgeier.com/resources/ for other ways I can help you.

  • My is more then 700/ per day..

  • I just can’t see how 400 milligrams can kill a healthy person I have friends who have taken upwards of a gram of caffeine throughout a football game

  • Great thanks for your channel, i got a lot learning from your video, and i have many question about fitness because im beginner. For my first workout im just doing 2 days a week and after that im feeling soo much pain on my body, what happen if i massage my muscle when its in pain/sore? Is it affect muscle gain? You know in my place( im from indonesia) when people feel sore at their muscle they often masaage their muscle. Sorry for looong comment

  • thanks for this very helpful advice man �� I always thought it was my asthma, but I always felt a heavy fog feeling in my chest, cause what is just said about drinking too much energy drink in a short amount of time. i always felt dumbed down drinking a pack of 4 energy cans and always had a feeling of ‘stoned’ eyes. thanks Nick for making me have a real good think about even too much energy drinks, aswell as pre workouts. it looks like only caffeine hit is coffee on Saturdays and Sundays at 7eleven

  • def true, my friend took 2 scoops one time of 250 mg per serving pre workout and he was light headed and almost passed out. took him a few hours to recover but couldve been worse. i myself have took 2 scoops b4 but didnt feel any negative symptoms besides a crash. some people are just hyper sensitive to caffeine. i think dying from 400 mg is not normal tho.

  • Kuch information chahiye ho kisi bi cheez k baare m. Open YouTube. And search…..bye guru mann �� cause we believe in guru mann

  • Well taking something that makes your heart race right before doing exercise that will make your heart race may be an overload issue

  • It can indeed depend.Body weight. Tolerance. How fast you metabolize caffeine.I’ve heard some people will metabolize caffeine slowly which causes them to feel more of a buzz.I think I must metabolize it more slowly because it can make me feel a little high,and zippy.That can help with a workout in that it increases energy.But it isn’t so good for needed focus.I will sometimes have to warm up for awhile to get over the peak.Then I move on to the weight lifting when it feels like I can settle in and cruise on my stamina.

  • here’s a small tip alter black coffee with beet juice and do this alternative day, and no addiction both are kind of similar with their components, so you don’t always hv to rely upon coffee, as too much is also not good, (what I do is instead of beet juicr I boil it and hv it 45 mins before workout, as to juice any fruit u hv to do a whole lot of work after u use the juicer, give it a shot):)

  • Thank you for the information on calcium depletion, now I understand why my legs feel so drained of energy lately. Looking forward to seeing more of your videos.

  • Preworkout sounds like total bullshit to me. How much can you attain on preworkout that you can’t without it. It sounds like every other gimmick these fuckers try to hock on their fans.

  • 7 days ago i took 800mg then went into the gym and after that I went running, then I came back home and fell on the floor with the worst body feeling ever, I was shaking and my hands were completely numb and my heart was pumping like 120 times per minute then I rushed to the hospital and as it turned out i was having a panick attack because my stomach was making too much adrenaline from the caffeine, 2 days later i had another panick attack but less simptoms ant yesterday yet another one but even less simptoms…..so caffeine is not goof for everyone, it stick in your body for like next 7 days but you get better

  • Every time I watch a workout video, they always have to begin by having a little white scoop of whatever. Why? Who needs the stuff? Makes you train harder? BS.

  • Sir how can remove preworkout from my body i was taking preworkout but after few days ha ve pain on my head and feel heartbeat fast and I’m taking medicine everyday what i do for relief bro please repto me

  • A couple of weeks ago i bought a new pre-workout, and they recommended one that had 350MG of Caffeine per scoop and they told me to take 2 scoops before training. Me not knowing that much about nutrition or supplements thought it was a normal amount. Later that day i took 2 scoops, vomiting ensued for over one hour and i had heart palpitations the whole day.
    Never taking Pre-Workout again!

  • Bruh only 400mg caffeine per day?? I’ve taken preworkout with 400mg in a single serving. Plus I take ECA that has 200mg of caffeine per serving 2-3x per day.. damn

  • You should do a video about compression stuff. (Be it shirts, tights, sleeves or whatever lol, here in Japan almost every single gym goer uses it)

  • I switched to a caffeine free pre workout, I even have it after coffee n do cardio while I am on it too. Those caffeine ones made me feel anxious for the entire day when I was at work, especially if I had coffee

  • Like cans of red bull as soon as someone opens one up i can smell the stuff and i know their is no way on earth that stuff can be any good for you.

  • If I make it through the rest of the day (took pre-work the night before just before going to the gym and have a 12hr shift tonight and can’t sleep before my shift starts) I’m never going to use a pre-work again. I’m 36 years old by the way

  • Pretty sure he’s talking about Leatherfaze here.Usually my resting heart rate is 55bpm and after 1 set of incline that pre had my heart rate up to 135. Pretty freaky shit, he’s definitely not wrong here.

  • Sir i have started taking Ultimate nutrition prostar whey protein.. Post workout from 22nd aug 14..
    My weight is 106 kg and i m 6.1ft tall
    My question to you is that when will I’ll be able to see some results, as i workout 6 days a week each body part separately on each day. Along with 30 mins of cardio

  • bhai yaar mai. 3xt. pre workout use krta hu aaaj mene bhut hard excise lgaai hai or yaar mene herani ki baat je dekhi hai ke mere lode ka. tnaaao bhut kamm hogya hai or khda v deri se horaha hai kya. hai bhai je btaaia plzz?

  • hey nick nice video, ( Do carbs take away coffee from the system?), i eat breakfast and then have 2 expressos in the morning and i just bought a preworkout with 400 mg caffeine, i wanted to know,
    killing it with the videos,
    Thanks in advance

  • So, I take around 100-500mg of caffeine a dey on top of a high does of vyvanse (60mg) or ritalin (80mg). I haven;t *had an issues yet but **FOR THE LOVE OF GOD DON’T TAKE NICK’S WARNING LIGHTLY.* I even have a family history of heart issues, I don’t even work out, but I’m terrified of the day my doctors tell me I can’t have stimulants anymore. Don’t push your luck, please. It’s very serious.

  • I just drink my daily morning coffee then go to the gym. I have several kidney stones and passed one 2 years ago. Horrible pain. All due to taking 2 scoops of pre workout for 2 yrs

  • Nick, please for the LOVE OF GOD, shut up because you do not know what you’re talking about, you have not read the literature, and you are just fearmongering in order to reap in views. The kid who died OBVIOUSLY had pre-existing heart problems, you can’t POSSIBLE be that naive to think he didn’t. STARBUCKS has a coffee that they sell that is above 400mg of caffeine. If you ever actually read the literature and studies on caffeine consumption, you would find the most recently meta-analysis found that 3-9mg/kg of body weight is a safe consumption level for a healthy individual IN A SINGLE DOSE. At 185 myself, that means I can take 750mg of caffeine in a single dose and be perfectly FINE. Not that this is recommended but 3-9mg/kg is found to be SAFE. Even if you split it down the middle at 6mg/kg at my body weight would be 480mg if caffeine in a serving. Even on the lower end at 5mg/kg that is over 400mg/kg. Please for the love of god, shut up, do some actual research, talk to leading experts in the field, and stop pushing this BS.

  • Man I never realized you are not suppose to take them more than a few weeks at a time I took them way too much I think they messed up my stomach I threw them away for good

  • I’m 15, hello
    I can drink 4 Bangs and feel nothing
    This is 1200mg of caffeine, or 12.5 cups of coffee. I have had up to 2 grams, I’ve never had a caffeine crash, ever… I consume on average about 500mg daily, or almost 2 Bangs.

  • I took one scoop of Hemo Rage back in 2010 for pre-workout and it scared the crap out of me. My heart was beating a mile a minute and I was shaking. That was the first and last time I ever took that neon green radioactive space junk.

  • Once i took 4 pills of hydroxy cut fat burner and 2 scoops of pre workout after i did the maths turns out i’ve taken over 1000 mg caffeine ofcourse the high blood pressure hit me and i had heart problems while i was on pre workout and insomnia cut the caffeine fuq that

  • I drink pre work out when i hit the weights and my exercise routines, i also drink a lot of water to exclude exons expluse it out but i am going to drink way more water now and also i am going to take pre work out 3 times per week now.

  • I take pre workouts only 3 Times a week, I take One Tub which has 30 servings, then after the whole tub I cycle it for probably 6-10 weeks, 1 Month minimum ( 1 tub lasts 10 weeks) on my Gym days I have NO CAFFEINE, only pre workout, and maybe a cup of tea ( which is 330mg per day which is 100% safe) taking 400mg per day is safe 99% of people unless you have problems! I used to drink 10 cokes a day 400mg ( but ever since taking pre workouts I drink things like Fanta, etc.. no caffeine, definitely on my gym days!

    Remember anything can kill you, look at the people that DRINK ALCOHOL FOR YEARS, a pre workout is safe if you use it properly just make sure you don’t live on it, take it for 10 weeks then cycle it for 4-10 weeks and if you only take it like 3 a week, that’s barely even half a week. Just be safe and do your research! I know people who drink 7-8 coffees a day that’s 700mg there still alive lol. caffeine is dangerous if you have above 700mg ) but I Never ever ever take more then 400mg a day ) always around 300-400 for me on the average on a gym day.

  • 500mg yes I agree is a bit much. But a 200mg single coop of pre workout is not harmful at all, especially if thats the only amount of caffeine you get. This video is a good warning for people using in excess though so respect!

  • I’m highly sensitive to caffeine but i also rarely perceive adverse affects. I don’t drink coffee often and never have but i do take a 200mg tablet in the morning if i have not slept enough and it has a huge benefit on my ability to focus at work. I also feel a huge benefit when climbing or at the gym, heavier weights feel much lighter and my body fires more smoothly. All this from only a 200mg caffeine tablet! I limit myself to 2-3 per week as i don’t want to increase my tolerance too much, (I’m also not sure if it works like that) And I really like how much benefit i feel.

  • QUESTION: How effective is Home Workout? Can I have the same gains doing home workout?

    I just started hitting the gym, but will be very busy with work soon that I don’t know if I can still have time to go to the gym. My gym bud recommended home workout. Can I still acquire some gains, in terms of muscle growth or strength? or maintain the gains I had at gym?
