Yes! Checkmate only uses ingredients that have been tested and used countless times, and our ingredients and lab are GMP certified. It is always a good idea to consult medical professionals before taking any supplements. See “Our Formula” for more information.

Intense focus is usually not conducive to falling asleep. Checkmate does not give any jitters or make you jumpy, but you still may find it difficult to fall asleep if you take checkmate within a few hours of bedtime, especially if you’re sensitive to caffeine.

As often as you want to perform well! Checkmate not only helps one-time performance, but many of the ingredients have been shown to have positive long-term effects on the brain. While there is certainly a limit to how many you should take at once, it is completely safe and potentially healthy to take consistently, following the dosages on the label.

Yes! All of our ingredients have been tested in rigorous scientific studies and shown to be effective and safe. Proper dosage and effect may vary person to person, but Checkmate absolutely works and will aid chess performance and foster long term brain health.

The serving size is 2 pills. We recommend that everyone starts out with one to make sure the effect is not too strong. After that, feel free to increase the dosage until you hit the “sweet spot” for your chess performance. NOTE: even though Checkmate is safe, there is always such a thing as too much. Based on the dosage of our ingredients, most of the medical community would not recommend taking more than 5-6 pills. It is always a good idea to consult medical professionals before supplementation.  

We recommend Checkmate for any time controls. Our formula is designed for classical, rapid, and longer blitz, but it will absolutely also help for shorter time controls or bullet.

Nope! Checkmate is beneficial for long-term brain health and is designed to avoid dependency. You will just wish that you had Checkmate with you!

No. Checkmate is the first product specifically designed for chess performance, and it is unique in its goals and ingredient list. Although, all of Checkmate’s ingredients have been used in many different supplements and products widely used by athletes, people in business, students, etc. However, this combination of ingredients doesn’t exist anywhere else.   

Generally, it will take about 10-25 minutes to feel the effects of checkmate, and the benefits will last for about 4-8 hours. This depends greatly on your body, metabolism, diet, other supplements, sleep, etc.

2 pills of Checkmate have 150 mg of natural caffeine. That's about the same as a large cup of coffee, but it has an even greater effect, and without the jitters or jumpiness. For our more caffeine-sensitive customers, Checkmate Decaf is coming soon.

Checkmate is a supplement. Since it is not a drug, it is NOT subject to FDA approval. However, Checkmate is 100% FDA-compliant, and it is manufactured in FDA and GMP-certified facilities.

Checkmate is specifically designed to meet the demands of chess. While coffee and caffeine pills also provide focus, they bring with them jitters, unease, and an elevated heart rate. Checkmate provides calm focus and a host of mental benefits for longer than both of these products in a way that is optimal for chess performance.

Short answer, no. Checkmate’s most powerful effects lie in its ability to increase available neurotransmitters and blood flow to the brain. No matter how often or for how long you take it, it will always improve your mental performance. That being said, there may be a psychological sense in which you “get used to” the powerful effects of Checkmate. Even if you start to feel the boost a bit less, Checkmate is still by your side and working in your favor.  

Both! Checkmate will help all levels of chess players, from your first game or your 10,000th. Checkmate provides calm, clear focus to its users, so if you are a beginner it will help you remember basic openings or spot those pesky tactics, and if you are advanced it will grant improved strategic creativity, help you remember deeper into theoretical lines, improve time management, and allow for more complex calculations and board vision.
