Celsius causes brain fog

Question

Celsius and other caffeinated drinks can lead to brain fog and fatigue.

Comments

I think that this claim definitely has some truth to it, however since the article does not directly call out Celsius, then that leads me to believe that the person to created this claim may have something against the Celsius drink, or maybe the company, considering that the brain fog comes from the caffiene in the drink, then it wouldn't make sense that other drinks containing caffiene would not also cause brain fog.

I don't agree with this claim at all. Obviously, if you consume too much of something it becomes bad for you. However, Celsius and other energy drinks are made to give you energy and essentially focus on whatever activities you're trying to do.  Celsius is also made with different vitamins and amino acids that help enhance mental clarity and physical performance. Many consumers report increased focus and sustained energy without crashes associated with traditional sugary energy drinks, especially considering that Celsius is made with 0 sugar. If Celsius did lead to brain fog, its products wouldn't be endorsed by so many athletes at both college and professional levels. These are people who's jobs require focus and lots of energy. Rather than blaming energy drinks, I think factors like an individuals diet, hydration levels, and caffeine tolerance .

This claim “Celsius and other caffeinated drinks can lead to brain fog and fatigue.” is found to be true followed by many harmful effects. Firstly when reading the provided article, the writer never actually states the issues being caused are by the caffeine within the Celsius brand themselves. In this case, the author could have gone to extreme assumptions for this claim to persuade the audeince, despite some truth in the statement. It seems that ther eis no direct correlation with Celsius itself rather than caffeine as a whole casuing brain fog within customers. An external article addresses brain fog in general stearing away from even the effects from caffeine. Brain fog is often linked to chronic fatigue syndrome (CFS), which affects about 1 million Americans. (Roche, 2025). Other validated sources address some negative aspects of caffeine intake; crashes, dehydration, and blood sugar irregualries.  Ultimatley, it is determined that although this claim is true, this specific article coverfing the effects of celsius are untrue and are made assumptions.

This claim that Celcius and other caffeine drinks cause brain fog is shown to be true in this article by providing multiple other sources. The article talks about various health risks most concluding in overuse of caffeinated drinks can cause brain fog. The article also provides multiple other reliable sources to back health concerns relating caffeine. Although the article is convincing, the claim could be biased from a personal experience.

I agree with the claim to some extent, but I believe the credibility of the article would be significantly enhanced if there were more resources and detailed information specifically about the Celsius drink itself. Providing direct references, studies, or expert opinions related to the product would help strengthen the argument and make it more trustworthy. Additionally, if the claim were framed differently maybe focusing on other aspects or backing up the statement with more concrete evidence the article would appear more credible overall.

Answer 1

This claim could kind of go in either direction, because while it is true that caffeinated drinks can lead to fatigue if over-consumed or consumed at the wrong time, there isn't a chemical component in these drinks that will inevitably cause this. Your article provided, Live Strong, is not a primary source that held a true experiment or study with Celsius or other caffeinated drinks, instead it made weak claims that sort of tie in to the main idea but also don't. The author is does not have experience in any form of science, especially not nutritional science, which can be a tell tale sign that they don't have the credibility to make these claims. The underlying truth of the article is that if taken at the wrong time, or if taken too much, caffeine can seriously mess with your body's ability to sleep properly which in turn leads to fatigue and brain fog. It does not say, however, that these drinks will cause this. So in a way your claim is true, caffeinated drinks CAN lead to fatigue but only if consumed against the recommended usage.

Comments

This is a very good fact-check. I agree that this claim is exaggerated because while caffeine can have negative effects on your body, it won't always.

Answer 2

The question is asking if "Celsius and other caffeinated drinks can lead to brain fog and fatigue."  Generally I would agree but this isn’t always the case and depends on individual factors. Caffeine does boosts alertness, but for some people, it can lead to fatigue or “crashes” afterward, especially if they consume high amounts or have a low tolerance. (For me this is the case) The title of the article is somewhat clickbaity because it implies a guaranteed outcome. A more accurate statement would be that caffeine may lead to brain fog and fatigue, depending on individual reactions.The Livestrong article offers general health advice but isn't a primary scientific source. It’s helpful for accessible insights but should ideally be cross-checked with more reliable, research-backed sources when evaluating claims about caffeine, brain fog, and fatigue.

A good source would be Mayo Clinic. They note that caffeine can disrupt sleep and, in some cases, lead to fatigue or mental fogginess, especially if consumed in excess or irregularly. Mayo Clinic on caffeine effects.

Answer 3

The way you re-titled the article made it seem more misleading than it really is. The original article is claiming that caffeinated drinks (including celsius) CAN cause brain fog, not that it does with certainty. 

There are various links to different sites scattered within the article proving and further explaining their claim, although I believe they may have over exaggerated for clicks. The sites provided by the author are a little untrustworthy seeing as most the links provided are .com rather than a more trustworthy .org. An article I found further exploring this topic is https://www.verywellhealth.com/brain-fog-8363295

The heading of the article is definitely over exaggerating for clicks, although they share some truth, it is a bit of a stretch.

Answer 4

The claim, "Celsius and other caffeinated drinks can lead to brain fog and fatigue."

Without evidence that can back it up, makes this claim misleading or not supported by actual science. When making claims about possible health concerns there needs to be some form of evidence from a reliable source. 

After reading this claim and doing some of my own research into the subject, I found that that there is no direct evidence to support the claim that Celsius drinks cause brain fog (1). However, it important to note that excessive caffeine intake can lead to side effects such as anxiety, increased heart rate, and nervousness, which might be mistaken for brain fog (2). It's always best to consume energy drinks like Celsius in moderation to avoid potential negative effects (3).

Answer 5

Brain fog cannot be attributed to Celsius, let alone energy drinks in general. Celsius contained 200mg of caffeine per can, which is just as much, if not less, more caffeine than a venti coffee at Starbucks. The Celsius website contains a full description and evaluation of their energy drinks, ranging from ingredients, common misconceptions, and approval of the FDA regarding their products as well as the NIH. However, there may be other energy drinks that could result in "crashes" or "brain fog", but that could be due to any other causes such as a lack of sleep.

Answer 6

This article claims that drinking Celsius can lead to brain fog. 

Throughout the article, it talks about how brain fog is caused by more than just drinking a caffeinated beverage. Brain fog can be caused by a number of things, such as, lack of sleep, mental health conditions, or stress. According to UnityPoint Health, "Dr. Stein says getting the right nutrients through a healthy diet, prioritizing sleep and exercising to sharpen concentration are three things to start with." While caffeine can be one of the factors that causes brain fog, it is more linked to getting enough sleep and eating healthy foods. According to LiveStrong.com, caffeine can be beneficial to your health, if not too much is taken, "it can even improve cognitive ability for some people — but, like any stimulant, it should be used responsibly." 

This claim was intended to draw in the reader, getting them to click onto the article. While, yes, caffeine can cause brain fog if too much is taken, caffeine is not the leading cause of brain fog.

Answer 7

This article is very misleading. While the article presented does discuss caffeine and brain fog the brand Celsius or any other large caffeine brand is not mentioned. Studies can prove that caffeine may lead to less sleep, but it does not prove that drinking Celsius leads to brain fog or is related directly to brain fog. Caffeinated drinks themselves have evidence to contributing to sleep deprivation which in turn may lead to brain fog and fatigue. During my researching I discovered Celsius does contain more caffeine compared to other energy drinks which may lead to other health problems, but not relating to brain fog. There is no evidence in terms of celsius causing brain fog. Improving sleep hygiene such as reducing caffeine intake can help relieve brain fog and fatigue. Therefore, while the article does hold some true statements it is exaggerated and misleading to the idea that Celsius causes brain fog.

Comments

Do you have any sources? Did you find any additional information besides that included in the claim?

Answer 8

The claim Celsius and other caffeinated drinks can lead to brain fog and fatigue is a little exaggerated since the article written by Dylan Rouche states that any type of caffeinated product can lead to brain fog. 

In the article Dylan wrote, he goes into detail about how drinking caffeine can not only lead to brain fog but also affect sleep patterns and, to an extent, everyday life.  Not only that, but he lists many other ways different patterns in your life can affect brain fog. He backs it up with a variety of studies, one of which is how caffeine intake affects sleep based on how many hours before you have taken caffeine. The study done by  Christopher L. Drake depicts how age and gender also affect how your body reacts to the caffeine in your body. 

Dylan doesn’t discourage people from drinking caffeine, he warns people to take the recommended amount of caffeine and getting enough sleep daily. He also states how keeping a healthy lifestyle will reduce the beginning effects of brain fog. Taking care of your body properly and watching your intake will result in a healthy way to overall consume caffeine.

Answer 9

This article on caffeine and brain fog raises some valid points about how caffeine might affect energy and focus, but it exaggerates the link between caffeine and a condition like brain fog. While it mentions that caffeine can lead to crashes or jitteriness for some people, the article leans heavily on the idea that caffeine might be the main reason behind ongoing "brain fog," a term that isn’t even medically defined. By suggesting caffeine dependence is a major factor in brain fog, the article overlooks other, more significant causes—like sleep quality, diet, or stress—that also impact cognitive function and energy. The story could give readers the misleading impression that caffeine is to blame for a broad range of mental lapses when the truth is much more complex.

Comments

Your argument here is thorough, and it makes sense, but you didn't have any evidence to back it up. If you had found information from a credible source this would be a strong answer to the claim.

Answer 10

While caffeine found in energy drinks can cause brain fog if you consume them too close to bedtime, therefore affecting your sleep schedule, the title of the claim here is using clickbait. There's no explicit mention of Celsius in this article. Looking at an article about brain fog from Cleveland Clinic, they state brain fog can be caused by a lack of sleep, which energy drinks can cause with their high caffeine content, but there are several other ways brain fog can be caused by as well. The ideas discussed in the main article supplied here can be applied to Celsius, but the title is misleading.
