What Is The Right Dosage of Caffeine Pills?
Caffeine pills are distributed from different companies. As such, they come with different daily dosage recommendations and package directions. If we had to estimate the average caffeine amount per pill, we’d say that most companies feature pills with between 100 and 200mg of caffeine.
Some may offer more or less, depending on the package, but this dosage is easily comparable to a cup of brewed black coffee. Depending on this same dosage and package directions, you may take less or more pills per serving.
Each product packaging should contain information about how many pills you should take per serving, how long they last, and whether they’re time-released. Keep in mind that the effect your body may produce from caffeine also depends on your constitution and nervous system.
According to the FDA, a healthy amount of caffeine per day that won’t compromise or jeopardize your health is 400mg. Depending on your health state, more or less can be enough for you. Slight exceeding of the recommended 400mg shouldn’t do you too much harm if you’re an adult.
However, within that 400mg of allowed caffeine, it’s important to consider potential caffeine-rich food that you may take during the day such as chocolate, or drinks such as coffee, tea, or some energy drinks. They also contribute to the overall amount of caffeine you take during the day.
Comparably to coffee, 400mg of caffeine can be between 2 and 4 caffeine pills. Also, 400mg of caffeine equals anywhere between 3 and 5 cups of black brewed coffee.
Even though we said that a slight crossing of the 400mg threshold shouldn’t do you harm, it’s possible to overdose caffeine. FDA report states that most of the side effects of caffeine abuse including heart attack and stroke were associated with consuming over 1200mg of caffeine per day.
Although large caffeine consumption, isn’t considered for pregnant women or those who are nursing (due to the risk for babies that can drink caffeine-containing milk) drinking caffeine pills can be safe if you consult with your doctor.
However, pregnant and nursing women, children, and teenagers, as those people with cardiovascular or some other chronic disease are more susceptible to caffeine poisoning.
One caffeine pill can have 100-200mg of caffeine, equal to a cup of black coffee.
You shouldn’t take more than 400mg of caffeine per day, which is 2-4 caffeine pills, or 3-5 cups of coffee.

How much caffeine does it take to kill you?
While there have been deaths attributed to caffeine consumption, they are quite rare.
It’s generally thought that the lethal dose of caffeine is 200mg per kilogram of bodyweight.
That means that a 180-pound man would need to consume around 16,363mg of caffeine.
That’s a lot!
To put that in perspective, that’s the amount of caffeine that you would get in 204 cans of Red Bull or around 160 cups of regular coffee.
You are more likely to die from your partner killing you for spending so much money on caffeinated drinks than you are to actually overdose yourself.
However, as usual, people who have pre-existing health conditions or who are sensitive to caffeine for other reasons should exercise care and talk to their health professionals.
|Age||Recommended Daily Caffeine Intake|
|Teenagers||100 mg per day|
|Average Adults||400 mg per day|
- If you have any questions about caffeine, please talk with your health care provider.
- If your symptoms do not improve or if they become worse, check with your health care provider.
- Check with your pharmacist about how to dispose of unused medicine.
This information is a summary only. Consult with your health care provider for additional questions or concerns about the use of caffeine.
How Does Caffeine Work?
The primary mechanism of action of caffeine is on the adenosine receptors which play an important role in our neural activity and thus have a strong influence on how tired or energetic we feel. When our neural activity slows down, we feel sleepy and when it speeds up we feel more alert and focused.
Adenosine is a neuromodulator in the central nervous system (CNS) which when bound to specific receptors, slows down your nerve activity making you feel sleepy.
Being fat-soluble as well as water-soluble, caffeine easily crosses the blood-brain barrier and binds to the same receptors. However, it doesn’t slow down the neural activity (5).
The neural activity speeds up as a result. It activates pituitary glands and produces hormones that trigger the adrenal gland to secrete more adrenaline. This gives you a burst of energy and increases your motivation and attention levels.
Summary: Adenosine binds to its receptors in the CNS and slows down neural activity that in turn calms you down and makes you sleepy. Caffeine is an adenosine antagonist that binds to these receptors itself because of its similar structure, causing neural excitability.
As you can see, caffeine pills have several advantages over drinking coffee. They’re cheaper, more convenient, often far more effective, and don’t carry side effects that coffee does. You can stay energized on the go and never worry about having to run to the bathroom in public again. With our helpful tips and mini reviews, you’ll be more productive than ever before.
Side Effects of Caffeine and Weight Gain
Caffeine increases the release of acid in your stomach, sometimes causing heartburn or an upset stomach. For those looking to lose weight, excess acidity is to be avoided, as acidity precedes cortisol release. The hormone cortisol causes the body to increase insulin release, impairs fat loss and generally predicts weight gains.
As a diuretic, caffeine will cause the body to purge water and thereby lose electrolytes like potassium and sodium. Caffeinated beverages do not typically cause dehydration, but caffeine pills can cause dehydration and incur vitamin deficiencies when not consumed with adequate water.
Heavy caffeine consumption should be avoided. More than 500-600 mg a day can lead to negative side effects:
- Muscle Tremors
Caffeine temporarily blocks a chemical called adenosine, a natural brain sedative, from being released. Thereby, you feel more awake for longer.
The effects of caffeine on sleep are largely determined by genetics, with most people falling somewhere between extreme sensitivity and near-total tolerance.
Healthy adults need around 8 undisturbed hours of sleep a night. Caffeine can interfere with both sleep and wake cycles, and sleep loss is cumulative. Through lost sleep, a heavy caffeine habit can lead to weight gain and fat retention resulting from cortisol increases in the system following sleep deprivation. Days after sleeplessness also show decreased impulse control, ie dietary discretion.
Consume with care.

How Should I Use Caffeine?
- Caffeine may be taken with or without food. If caffeine upsets your stomach, take it with food.
- Do not exceed the recommended dose of caffeine. Caffeine can be habit-forming.
- Most OTC medications used for mental alertness contain 200 milligrams of caffeine per tablet or capsule. The usual maximum recommended dose of OTC caffeine is no more than 200 mg every 3-4 hours, or 1600 mg per day.
- Do not double-up on your caffeine dose if you should miss the time for next dose.
- The average cup of coffee contains 150-200 milligrams (mg) of caffeine per cup, while a cup of tea will have about 60 mg of caffeine. Cola products have about 30-40 mg of caffeine, and most energy drinks have about 60-70 mg. Be sure to account for any dietary caffeine that is consumed.

Risk and Side Effects of Caffeine Intake
Caffeine, when taken in moderation has many health benefits (28). But a dose of 5gm or more is considered to be toxic and sometimes can be fatal. Some of the symptoms of caffeine overdose are:
- Arrhythmia (problem with the rhythm and rate of the heartbeat)
- Tachycardia (increased heartbeat)
Caffeine can overstimulate or irritate a person depending on its dosage. Some of the side effects are:
- Gastric problems
- Reduced calcium absorption thereby causing osteoporosis
- High blood pressure
- Risk of abortion
- Infertility in men and women
Summary: Caffeine in moderate amounts shows several health benefits. But some people may experience side effects. Studies have confirmed that a dose of or above 5mg can be fatal.
Who Shouldn’t Use Caffeine Pills
With all these things in mind, here are the groups of people who shouldn’t drink caffeine pills to avoid the aforementioned risks.
Pregnant and nursing women Those who suffer from insomnia, sleep apnea, and other sleep disorders People who experience headaches and migraines regularly People with cardiovascular disease People who suffer from asthma People with acidic reflux and GERD People with mental disorders such as anxiety People who have ulcers. Diabetics
What should you do if you have caffeine side effects?
High doses of caffeine can cause chills, agitation, dizziness, headache, vomiting, nausea, fainting, indigestion, lightheadedness, and seizures, according to the Mayo Clinic. You should check with your doctor immediately if any of these symptoms occur. You should get emergency help immediately if you show signs of overdose, which include irritability, nervousness, rapid heartbeat, and trouble sleeping. Other side effects, like a rash or dry skin, can occur but do not require medical attention.
What if it’s just a case of caffeine jitters? For minor caffeine ingestion, supportive measures, like drinking water and talking a walk, can help, Link suggests. More severe cases may require intravenous hydration or medications to treat irregular heart rhythm, for example. In life-threatening situations, dialysis may be the best option.
How to Take Caffeine Pills Safely
Follow the instructions on your caffeine pill label or ask your doctor for recommendations on how to take caffeine pills.
Follow these guidelines:
- Limit your caffeine intake to 400 mg of caffeine per day. Remember that foods or drinks with caffeine, like coffee, tea, soda, caffeine drinks, and chocolate milk, have added caffeine. It may be best to avoid them when you take caffeine pills.
- Avoid caffeine pills close to a time when you’re trying to sleep.
- Avoid over-the-counter medications like cold or allergy medications unless you talk to your doctor first.
- Avoid grapefruit juice when you take caffeine pills because it may increase the effects.
- Watch for signs of overdose, like a fast heartbeat, nervousness, irritability, and trouble sleeping.
Are There Risks and Side Effects?
Just like anything else, caffeine pills have risks and side effects if you don’t take them in moderation and as advised by their manufacturers. Some possible side effects are:
- Mild heartburn
- High-blood pressure
- Feeling dizzy
That is why it’s generally recommended to do a bit of research first and find the best caffeine supplements rather than choosing a brand at random. Not every manufacturer invests effort into creating a high-quality product that’s as unlikely as possible to have such side effects.

The Bottom Line
Nothing beats caffeine when it comes to enhancing your energy levels and memory, and helping you burn that stubborn fat. As the market is jam-packed with companies claiming that their product is the one for you, it can be tricky finding what you need. Hopefully, our list will help you find a product that will fully meet your needs regardless of why you need the extra energy boost.
For those looking for a brief boost in their weight loss efforts, healthy sources of caffeine provide proven results. The stimulating qualities of caffeine make it a great complement to a workout routine, whether for the short or long term. Ultimately, a caffeine dependence will diminish the metabolic and fat loss potential for caffeine, but if you can balance and cycle your intake there may be an opportunity to preserve minor changes. Be sure to keep total consumption below 500 mg per day and apart from bedtime. Sleep loss will cause weight gain, so insomnia and restlessness from caffeine should be avoided. Choosing natural sources of caffeine, such as green tea and coffee, will provide additional benefits aside from those contained by the caffeine. Cheers to your health!
