How Long Do Caffeine Pills Take to Kick In (And Wear Off)

All hail, beloved caffeine, the world’s most widely used psychoactive stimulant. Caffeine is widely consumed via coffee, green tea, black tea, energy drinks, cocoa, pills, and other forms. According to research by award-winning author Michael Pollan, caffeine was first discovered in 1000 B.C. in China, and its popularity remains today. Pollan's research suggests that 90 percent of the planet consumes some type of caffeine daily and the caffeine market is projected to become a 1.2 billion dollar industry by 2031.

Although your brain may go directly to coffee when you think of caffeine, it can be derived from natural or synthetic sources and shows up in a wide variety of modalities for consumption. Caffeine pills have become a popular way to boost alertness, energy, and concentration, and are often utilized as a form of pre-workout to help you get the best workout. But what is caffeine? How does it affect your workouts and your nervous system and how long does it take for them to kick in and then wear off?

What is Caffeine and What are Caffeine Pills?

Caffeine is a naturally occurring stimulant processed through the central nervous system. As a psychoactive substance, caffeine consumption may affect mood, consciousness, and cognition, and each person will have individual differences based on their brain sensitivity. It's mainly used as a eugeroic aid, which is something that promotes a wakeful or alert state, but also may contribute to increased focus and productivity.

Caffeine pills are an optional way to ingest caffeine that doesn't require you to drink it, making it a unique option set apart from more traditional forms of caffeine which are normally found in beverages. For those who have a hard time with the taste of tea, coffee, or energy drinks, caffeine pills may be a great alternative to consuming caffeine.

Although structurally identical, caffeine can come in a synthetic or natural form, and caffeine pills can contain either type. The main difference is that synthetic caffeine is easier to source, and therefore, creates a more affordable product. Synthetic caffeine is approved by the FDA as a safe supplement and has similar benefits and side effects as natural caffeine.

How Much Caffeine Should You Consume?

According to the National Coffee Association, the average American adult consumes three cups of coffee per day, which is equivalent to around 285 mg of caffeine, or 90 mg of caffeine per serving. In comparison, the average caffeine pill contains between 100 to 200 mg of caffeine per pill, which makes it a highly concentrated caffeine form.

The suggested limit on how much caffeine you should drink daily is maxed out at 400 mg per day for average healthy adults. The dosage and effects of the caffeine pills will vary depending on your body weight, metabolism speed, and other health factors including body composition and whether or not you're on certain medications that may change the effects of caffeine.

How Does Caffeine Work?

When we take caffeine pills, energy drinks, or a morning cup of coffee, it starts in the gut, enters the bloodstream, and works its magic through our nervous system. Caffeine is a diuretic, which means it flushes fluid and salt out of the body. Because of this, you'll want to make sure to properly hydrate when you consume caffeine and caffeinated drinks.

In its chemical makeup, caffeine is very similar to adenosine and therefore works very similarly in our system. Adenosine is a naturally occurring neurotransmitter that has various bodily roles, including regulating your sleep. As adenosine builds up in the receptors, it causes you to become drowsy and induce sleep.

Because caffeine is similar in its makeup, it binds to adenosine receptors and blocks the adenosine buildup and concurrent drowsiness. Therefore, it may lead to more mental alertness, increased focus, and improved cognitive function, and may help you stay awake for extended periods. Most people experience positive cognitive benefits from caffeine consumption, but it will vary based on personal factors.

How Long Do Caffeine Pills Take to Work?
