6 Best Caffeine Pills (2023) Reviewed and Compared

Never miss a glorious update - click here!

A simple caffeine supplement may be one of the areas where you think all supplements are the same, or basically the same, and it’s a matter of choosing the most convenient.

However, this is not true at all. Caffeine pills are not created equally.

Some contain cleaner (frankly, better) forms of caffeine from higher-quality sources. They can, and often do, contain other ingredients, which may be helpful or not depending on your goals and why you’re taking it.

And unlike a cup of coffee, for example, you take the dose all at once, and you can only shift it in increments. So the dose is also an important factor.

Taking all of that into consideration, here are the 5 best caffeine pill supplements on the market.

1) Kaged PurCaf® Caffeine

Check Lowest Price

Price: $14.99

Best Overall. Kaged’s caffeine product uses the highest-quality form of caffeine you can find: organic PurCaf® caffeine.

Unlike most caffeine pills, this is 100% natural, organic, non-GMO, chemical-free, vegan, gluten-free, and third-party tested (and approved for sport).

Kaged’s caffeine comes from organic, green coffee beans. In contrast, a lot of products out there are made from synthetic sources. It provides a smooth, clean, lasting energy.

And, it comes in at a very affordable price. Often other companies who use premium caffeine will charge an excessive amount in order to boost their margins. But Kaged gives you the highest-quality caffeine at a great price.

Every bottle contains 100 capsules with 200mg of caffeine.

2) California Gold Caffeine + Theanine

Check Lowest Price

Price: $12.00

Caffeine and theanine have a synergistic effect. That is, the sum of the benefits is greater than its parts. This has been studied in several contexts. For example, caffeine and theanine together seem to improve ADHD symptoms in children more than each of them on their own (Nature).

In fact, in nature they often occur together, like in green tea.

So if you’re using caffeine specifically for anything related to productivity, like studying, working, or creativity, this is a great option.

It also contains cocoa and matcha, as added bonuses.

And it’s vegan.

Each capsule contains 100mg of caffeine and 100mg of l-theanine. Each bottle comes with 60 capsules.

3) Vyvamind

Check Lowest Price

Price: $49.99

Best for productivity. Vyvamind isn’t strictly a caffeine supplement. It contains an array of high-quality ingredients. Every serving has 75mg of caffeine, along with b vitamins, l-tyrosine, l-theanine, and CDP-choline.

This is a supplement for overall focus and attention, without the crash common with high amounts of caffeine. 

I wouldn’t take it as a pre-workout supplement, as it’s designed for mental focus and clarity, but for studying or overall productivity, its quality and comprehensive formula are hard to beat.

The downside is the price tag. With Vyvamind, you’re paying for a lot more than a caffeine supplement.

4) Performance Lab Caffeine +

Check Lowest Price

Price: $44.00

From a pure comprehensive and quality standpoint, this product is tough to beat. They use, like Kaged, a natural caffeine source and limit impurities across the board.

Each capsule has 50mg of natural caffeine. 100mg of theanine. 250mg Ajipure® l-tyrosine, and b vitamins. L-tyrosine has also shown benefits for cognition.

The downsides are the value. Each bottle only has 30 capsules per bottle, and the price per serving is way more expensive than other products. 

But if cost is less of a factor for you then this is the most all-encompassing product on the market.

5) EU Natural Elite Caffeine + L-Theanine

Price: $19.99

Best for lower caffeine dose. The average cup of coffee contains 125mg of caffeine. Most caffeine pill products contain between 100-250mg. If you want a lighter dose, though, you can try EU natural’s product, which has just 50mg of caffeine in each pill.

It also has 100mg of l-theanine, making it another great option for studying.

Each bottle contains 120 capsules.

6) Muscletech Platinum Caffeine

Price: $7.49

If you’re looking for a higher dose, this is a great value. Every pill with nothing but caffeine contains 220mg of caffeine. Every bottle has 125 tablets, so this product is just pennies per dose.
