Caffeine Capsules


  • 100% pure Caffeine
  • 200 mg per serving
  • Warning: highly toxic in larger quantities

WARNING! Caffeine is HIGHLY TOXIC in higher quantities. Excess use with as little as a few grams may result in death. DO NOT use more than 200 milligrams (mg) of Caffeine in a single serving, or more than 600 milligrams (mg) in a day. Accurate measurement requires a milligram weight scale. Do not take if you have a history of heart disease, or if you are pregnant or nursing. Consult your physician before taking this product.


Serving Size & Timing

As a dietary supplement, take 1 capsule every four hours, up to three times daily. DO NOT use more than 1 capsule in a single serving, or more than 3 capsules (600 mg) in a day. Caffeine being consumed from other sources, such as coffee and sports drinks, should always be taken into account when apportioning out the remaining supplement amounts to avoid chance of accidental overdose.

This product should be avoided by anyone who is pregnant, nursing or has a history of heart issues, liver issues or insomnia. If diabetic, it is important to consistently monitor blood sugar while consuming this supplement. If on any other drugs, medications, or suffering from any other ailments or illnesses not mentioned here, it is best to consult a medical professional before usage of this supplement.

Nutritional Information

Supplement Facts

Serving size: 1 capsule
Serving per container: *
Amount Per Serving % Daily Value**
Caffeine Anhydrous...200 mg *
* Daily Value not established.
** Based on 2,000 calorie diet


Sugar, soy, dairy, yeast, gluten or additives

As a dietary supplement, take 1 capsule every four hours, up to three times daily. DO NOT use more than 1 capsule in a single serving, or more than 3 capsules (600 mg) in a day.



This Caffeine supplement comes as a fine white powder and is considered pharmaceutical grade because of its strength and its purity sans excess fillers and additives. It should be stored in a dry area away from any heat or light sources.


Taken in small servings, some of Caffeine’s side effects are immediate, including an increase in body temperature, dilation of the pupils, frequency of urination and increased metabolic rate. Although Caffeine provides temporary energy, cognitive functions still need real sleep to be fully restored; Caffeine should not be used as a substitute for a good night’s sleep.

The ways in which Caffeine can affect someone depend on many factors, the most important of these being height, weight and resistance to Caffeine already established. Those with little exposure to Caffeine are already more likely to experience side effects from the drug almost immediately and at a more intense level.

Taking too much Caffeine at once can cause elevated blood pressure, restlessness, headaches, irritability, nausea and increased heart rate, which could be very dangerous. It should also be noted that Caffeine is extremely toxic in large doses. The larger the dose, the more likely one is to experience negative side effects. In some cases, large doses of Caffeine beyond the recommended daily value could even be fatal. This information is not to be taken lightly.


Due to varying import regulations, not all of our supplements are available to international customers. This product is restricted for sale in the following countries:

Customer Reviews

Works out great!
This caffeine product is great, premeasured in capsules so I just dump in my own morning energy concoction. Thanks! This was a review on a free sample from purchasing other bulksupplements products.*

On 5/2/2019 Keith said...

Good energy
If your looking for something to give you energy straight up, then this is the product for you. I won't recommend if you have heart problems but other than that it's great.*

On 4/27/2019 Elijah said...

Capsule sizes are perfect
I appreciate my caffeine fix and these pills work great. I'm actually really happy they come in pills because I think I would take too much of the powder by accident if I just had the powder form. I usually take one of these in the morning and one in the afternoon and it's perfect. I take it with my pre-workout that I built myself from products on bulk supplements and it's good quality, and a lot cheaper than what I used to spend on pre-workout. 200mg is perfect amount each serving, I used to take pre-workout that was 300mg or more and it was too much. *

On 4/4/2019 Andrew said...

Cheap and Effective
Cheaper than buying a premade pre workout and gets the job done quickly.*

Very Stimulating
I have been told by my MD that 100mg was the most I should take, so I cut open the caps so I can split the dose and this works out great.*

On 12/24/2018 David said...

Very Stimulating
This is the best bang for buck caffeine supplement. The pills are small indicating they are pure, no filler. I take one first thing in the morning and I'm still going strong in the afternoon with excellent results*

On 12/23/2018 DAVID said...

Works great!
Got this as a sample. It's caffeine and works as expected. No gimmicks!*

On 12/18/2018 Richard said...

The Ultimate Secret Ingredient
These capsules are so quick and easy. I always include one in my daily preworkout after a long day at work and it fuels to me to success. They are especially helpful during the winter when going out in the cold seems like a daunting task. All I do is pop one and within a few minutes I'm full of energy and I feel like I can tackle whatever I'm challenging myself to do that day.*

On 12/10/2018 Benjamin said...

Excellent Product
Being able to carry around caffeine in your pocket is as awesome as it is convenient. In my opinion, 200mg is the perfect amount of caffeine per capsule. Personally, I take 2 when I wake up before working out and 1 every 2 hours for the rest of the morning, or as I need it. Its so much easier than drinking a ton of coffee and way better than any energy drink. I highly recommend anyone to try it, as I use this product daily and love it.*

On 11/28/2018 David said...

This stuff rocks your world!
Always ready to GO and do anything. Workouts - work, you name it. Super convenient and no longer need coffee!!*

On 10/31/2018 Loren said...

Perfect size, great product!*

On 10/23/2018 Emmaline said...

Caffeine pills; just Amazing!
These Caffeine pills added to my pre-workout have given me an extra push to my workout routine. It is also an excellent fat burner. Regarding the dose, I think it depends on the tolerance you have to caffeine. I have been drinking Cuban coffee (Espresso) for the last 40 years; so I have to use two capsules and my espresso shot after that before hit the Gym. I feel a lot of energy but no jittery or any side effects. I strongly recommend it.*

caffeine capsules
love these caffeine capsules.
I work night shifts and these little 200mg capsules help me make it thru the night without the jitters.
they are also good to take with a pre workout supplement to get great workouts.
I highly recommend this product. I love I have purchased many products from them in the past and have never been disappointed*

On 9/12/2018 GEORGE said...

Part of my simple pre workout
Keeping my pre workout clean and simple, includes using caffeine capsules. They don't bother my stomach and provide me with just the amount of focus and intent at the gym. *

On 7/27/2018 Marnie said...

Only way to take Caffeine
No longer need to drink cups of coffee. Natural Caffeine in my water is better, great in the morning to get up and go with no jitters.*

On 5/23/2018 Owen said...

Excellent product
I absolutely recommend this product if you are looking for a little boost of energy without the jitters. I have used them before workouts and throughout the work day when I need a little pick me up. They work great and not once have let me down. Shipping was super fast also, product arrived in no time.*

On 5/17/2018 Melvin said...

works for sure
definitely improves energy levels, I split open the capsules since I hate taking pills and just mix it into whatever else i'm drinking. *

On 5/16/2018 Samuel said...

I am currently a senior in high school. This means two things: I have very little time and almost no money. This is perfect for me. I take this first thing in the morning and in my last hour of school to give me a boost. I wake up at 4:30 am to workout every morning and this product makes getting ready and having energy a breeze. I then take it in my last hour to kick in before baseball. There is no crash; they are easy to take; they are cheap; and they work amazing. *

On 4/26/2018 Alexander said...

Great product
Bulk Supplements are the best products. The Caffeine caps are great. This is just enough caffeine to keep me going without getting jitters. 1 small capsule is all I need. One thing I truly like about Bulk Supplements is that there seem to be no additives. No added sugars to products, just pure product. I plan to order more of the caffeine supplements and BCAA.*

On 4/2/2018 Ginna said...

Defaulting to capsules
Being unable to purchase caffeine powder on its own - that is, uncapsuled powder - I naturally defaulted to purchasing this product.

I guess I'm in a position to judge the product negatively, having been made (by I guess federal law) to buy something not quite suited to the use I needed to put the product. But I will not do so.

I am making caffeinated shampoo with these capsules. Naturally I have to open each one, pouring - (I can't remember how much exactly) - approx. 8 capsules' worth of powder into a few teaspoons (4 oz) for the shampoo formula. I don't intend to supplement the product orally.


Consider my positive review as taking into account the excellent service this website provides.*

On 3/26/2018 Connor said...

Caffeine Caps
Another great product from Bulk Supplements. A great addition to my morning. The product is clean and gives me that extra pick up I need to complete my daily workout routine. Try it you'll like it!!*

On 2/1/2018 George said...

On those days when you feel sluggish, these give you that extra boost to get you through the workout. Another great product from BulkSupplements.*

On 1/30/2018 Jason said...

It works well and I take one every morning*

On 1/24/2018 Anand said...

Love these...
Take one 30 min before my workout and im rocking and rolling at the gym. Great for getting my through my workout at full intensity. *

Caffeine Capsules
This is a clean product. I quit coffee 6 months ago and was concerned this product would have the same affects as coffee with jitters and crashing. It doesn't. I like it. *

On 1/10/2018 David said...

Hands down the best energy supplement I’ve taken. My wife has even replaced energy drinks with these. I take them before a workout and get just the boost I need to power through. Highly recommended.*

On 1/9/2018 Mathew said...

Caffeine Caps Are Great
I was getting frustrated with my morning caffeine options because the drinks and powders i used all changed over a period of time and i dont love coffee or it doesnt work the same. i've taken other caffeine pills before and hated them. I finally broke down and tried these. These are awesome! NO jitters. No crash. No adrenal fatigue. like, what do they put in all this other crap to cause that?!?! Its a small pill and smooth energy. I highly recommend this and this will be my new go-to caffeine source for morning caffeine.

Great capsules!
Great capsules and great price!*

On 11/4/2017 Anthony said...

Totally quit coffee!
I ordered these use in addition to locally purchased Jet Alert. I do think these offer better overall experience, but I do like a caplet, in that I can easily break off a smaller amount. This is so much cheaper and easier than all the fuss and mess of coffee. Thanks for another great product :)*

On 11/2/2017 Liza said...

Nice boost
It's caffeine, we all know what it does. This product is nice since the capsules are already in the dosage needed.*

Great for my early morning workout.
gives me that extra boost I need.
shipping was fast once again!!!*

Way better than Vivarin and No-Doz
I bought the vegetarian capsules and they are amazing. I am a nursing student in college and I have been taking Vivarin for months and I fall asleep on it. When I tried these capsules for the first time(the same day about 6 hours after I took Vivarin which made me tired as hell), these capsules gave me a HUGE jolt of energy at work. I couldn't even stand still. There is no stomach upset or negative side effects. I love this stuff! As I said above, you might receive a few broken or empty capsules but so what. These capsules are the real deal. They are the best money can buy. Good bye Vivarin and No-Doz!*

On 9/9/2017 Adin said...

These caffeine pills do the trick.
They work fantastically. Just as you'd expect it. Potent boost to energy!*

Same Great Caffeine in Convenient Capsules
Years ago I purchased the pure caffeine powder here at BulkSupplements and now I needed to re-up. But the powder is no longer available to the general public, only the capsules. I liked the ability to use as much or as little powder as I wanted. But now that I have the capsules and have been using them for a couple weeks, they are much more convenient and 200mg is a good dose. And much less danger of people accidentally overdosing, which is good for the inexperienced pure caffeine user. *

On 8/16/2017 Rico said...

Good pre workout
Used to spend $2.50 for a coffee before workout. now for a nickel i add the powder from a capsule to my green drink. Works perfect. Very fast shipping from bulk supplements.*

Keeps me from mindless snacking
I work out early mornings before work which leads to me getting a little lethargic by the end of my work day which then leads to mindless snacking on sugary junk. I find if I take one of these little guys early afternoon on workout days it keeps my energy levels up so I can stay focused on work and not looking for snacks in the work fridge or co-workers candy stashes!*

On 6/21/2017 Blair said...

Pre-Workout Power!
This is a great solution to my DYI pre-workout drink. The capsules are easy to twist apart to mix in with the other sups. Easy to manage the measurements to prevent overdose since pre-measured capsules. Recommend this product to anyone looking for an extra boost! *

On 6/2/2017 George said...

Great Product
One capsule 45 minutes before my workout was better then the usual black coffee I drink. I felt more energetic and motivated. Great product for sure!*

On 5/23/2017 Matthew said...

Cost Effective Method of Getting Caffeine
I am a college student so I don't have a lot of extra money lying around. I enjoy energy drinks like Monster, but they cost a lot and forget pre-workout supplements, they are way worse. These Caffeine pills work exactly how you would expect them to, and they were so much cheaper than other places. Great purchase would buy again.*

On 5/2/2017 Alexander said...

Works great

Simple caffeine pills that do the job, straight and to the point. Using this for a homemade preworkout and it works great! *

On 4/20/2017 Mike said...

300 Vegetarian Capsules
Kind of hard to open the capsules to put in my pre workout. Wish they could just sell the pure powder to the public, but that would be a bit dangerous I guess. Anyway, solid caffeine, solid price, difficult capsules. Would give 5 stars if so many capsules weren't broken during delivery, about 10-15% of them.*

On 4/5/2017 Robert said...

Excellent choice to save alot of money
JUST TOOK SOME BEFORE I WROTE THIS REVIEW. FEELIN GOOD HAHA. I work in an office and need something to help stay awake and focused but energy drinks (though taste great) get extremely expensive. I use a pill in the morning to get me out of bed and in the evening while at work, excellent economical choice. Great energy, not really any jitters. Just good solid caffeine. *

On 3/22/2017 Chase said...

1 pill gives me the energy I need for the entire day or for an intense workout! I got 300 capsules, so basically I have enough caffeine for almost a year and it was only 14 bucks!!! That's saving ALOT of money in the long run!*

On 3/11/2017 aaron said...

Gelatin Capsules
only been taking for a couple of days and already love them. Love the energy it gives and how I feel throughout the day just take one of these every morning. Definitely buying again.*

On 3/1/2017 Jerry said...

Quality caffeine, smaller capsules than most other brands
I like to have caffeine pills with me in case I need an energy boost throughout the day. I really like how these capsules are smaller than most other brands and this is likely due to the pure, filler free formula BS is known for! Another great product by BS!*

On 2/26/2017 Carson said...

Great Deal, Great Results
The price for the capsules are very affordable and I've noticed results very quickly. It's a great weight loss supplement.*

On 2/22/2017 John said...

Better than coffee!
These pills are small and go down easy. The effects dont take long to kick in and is stronger than drinking coffee. These will definitely help me take my training to the next level*

On 2/1/2017 David said...

100 Vegetarian Capsules
Smooth clean energy. Great for intermittent fasting and keeping energy levels high and suppressing hunger. Comes in a super convenient package. Had caffeine pills from another brand in a bottle but the rattling around was annoying. This package is easy to toss in a backpack and bring around all day*

On 1/18/2017 Ryan said...

Capsules dented
I ordered the veggie caps and a lot of the capsules (but not all) are slightly dented in on the ends. This doesn't seem to affect the product, but it raises questions about quality control. However I have been using them and they work. They don't seem to work any differently than the much cheaper Jet-Alert ones I've been taking though, so I can't really rate them five stars.*

On 1/13/2017 Paul said...

The best deal on the internet
300 count worth of capsules, 200mg of caffeine per capsule, $20.00 total..... This is the best deal I have run across. Caffeine is a must and with an easy to swallow 200mg capsule, it is a no brainer. Will 100% order this product again. *

On 1/12/2017 William said...

100 Gelatin Caps
Great product. I really enjoy purchasing bulksupplements products because they're affordable, the staff are professional and friendly. Best of all they offer COA'S per request. This is big for me as I like to know precisely what is going to be consumed in my body. Overall the synthetic caffeine is great, works just like it should, the reason for the four star rating is due to the packaging. Some of the capsules were broken upon arrival, not the greatest form of packaging in my opinion. *

On 1/2/2017 Josh said...

caffeine caps
great products will use again*

On 1/1/2017 Robert said...

I've tried other caffeine supplements in the passed which took to long to kick in or either I didn't feel anything or I felt too much. These little pills actually are on the money.. *

Caffeine caps
Great product in an easy-to-consume form. However, some caps were damaged in the bag during shipment. I prefer to cap my own powders, so I wish bulksupplements would offer pure caffeine in powder form to consumers again.*

On 11/25/2016 Emre said...

great product great price
I take one of these every morning before working out and it does exactly what it is supposed to do. Price point is great and the product performs every time.*

On 11/15/2016 Todd said...

It's caffeine
The capsules are small, easy to swallow. Nice to have to get some caffeine without drinking coffee or an energy drink. For times when one wants to spread out the dose, open the cap and sprinkle out the powder, it dissolves readily, no noticeable taste. I like to add it to some Tang along with taurine powder - viola! Energy drink to sip!*

On 11/10/2016 April said...

Quick and to the point
Another quality product offered by bulksupplements, I use this with my homemade pre-workout. Buying my products from bulk supplements has not only saved me money but allowed me to cut out the products that I had concerns about in other pre-workout mixtures. *

Caffeine capsules
These are a great option to get your caffeine. The amount is already measured out in the capsule. It is very convenient to be able to take one without having to measure out the caffeine with a scale. I will be reordering it. 5 stars.*

Extremely satisfied.
I take it in the morning and feel a energy boost, as expected with caffeine. I love the pill size, they are not at all hard to swallow, and the amount lasts a perfect time. I take two everyday and find that it has zero effect on my sleep. Great product, would recommend to friend. *

Caffeine (Synthetic) Capsules-100 Gelatin Capsules
I was finding myself a little tired sometimes and in need of a tiny pick me up but I didn't want the added calories or fillers of other types of caffeine. This provided me with a little pep and no side effects I had to drastic high or low from it. It was a quicker wake up solution than others I have tried.*

On 9/11/2016 don said...

Pre-Workout Must
Got this to take with my pre-workout blend (that I of course buy from here and mix myself at a fraction of the price compared to other places). Acts quickly and helps me get into workout mode at 5:15 every morning. Will continue to use.*

On 8/23/2016 Timothy said...

Great addition to my morning smoothy
I've added 2 capsule to my morning smoothy which takes me about 3 or 4 hours to finish. I can tell when its in there by an added mental "zip" and it blends right in without any noticeable taste. It certainly aids in decreasing my coffee consumption.*

On 8/11/2016 James said...

Another Great Product!
Recently received this product and couldn't be more pleased. Quite a powerful substance, the come down isn't great but nothing more than having a few cups of coffee. Very pleased overall and highly recommend this to anyone!*
