How does caffeine work?

Cup of coffee

Caffeine is a nervous system stimulant reputed to eliminate drowsiness and bolster energy levels, giving you the focus to tackle the day ahead.

Not only that, caffeine has its fair share of benefits which can help support health goals you may have. But, it’s good to make an informed decision as to which type of caffeine to use and how much you should have. 

For most people, it’s safe to consume caffeine in a moderate amount. But having the stimulant in large doses or too frequently can pose health risks. So, let’s deep dive into one of the most talked about stimulants—caffeine anhydrous. 

The science behind caffeine anhydrous

When you consume caffeine, it enters your brain via your bloodstream, mimicking adenosine (a more naturally occurring caffeine compound in your body).

Now, while adenosine is a neurotransmitter that causes you to slow down and feel sleepy, caffeine takes adenosine's place by attaching itself to specific receptors in your brain and blocks those relaxing effects. Instead, it causes the opposite reaction, helping to awaken and rejuvenate your brain—this makes you feel more alert.

Adenosine is a neurotransmitter that promotes relaxation and sleepiness by binding to its receptors in the brain. 

When adenosine binds to its receptors, it slows down nerve cell activity, leading to feelings of drowsiness and fatigue. Caffeine anhydrous works by blocking these adenosine receptors, preventing adenosine from exerting its calming effects.

But that is not all it can do…

Anhydrous caffeine can also help to boost the effects of other natural stimulants in your body, including dopamine, norepinephrine, glutamate, and adrenaline.

Quick note: Caffeine works whether you have it from its natural source or as caffeine anhydrous. Either way, you'll begin feeling the effects of caffeine within an hour, and it will wear off after three to four hours.

What is caffeine anhydrous?

Dehydrated coffee

Caffeine anhydrous is a form of caffeine that is dehydrated, which means it contains minimal to no water content. It’s a powdered form of caffeine often used in dietary supplements, energy drinks, and caffeine pills.

Would you believe that anhydrous caffeine is a naturally occurring substance you can find in roughly 60 different plant species? It's true. Yet of those 60 plants, most people are more familiar with coffee beans, tea leaves (green tea) and cacao.

Caffeine anhydrous vs caffeine: What’s the difference?

They may look different, but chemically they are the same.

Take, for example, caffeine anhydrous. It comes from the seeds and leaves of coffee plants. But, unlike traditional coffee (cacao and coffee beans), which are natural substances rarely altered, caffeine anhydrous differs because all of its water—and other chemical components—have been completely filtered out, leaving behind a white crystalline powder.

In other words, caffeine anhydrous is a processed, dehydrated form of highly concentrated caffeine from coffee that is easily added to gum, sports drinks and energy bars to help boost energy, weight loss and physical performance.

Caffeine anhydrous: Pros and cons at a glance…

Pros: It can provide you with a more standard caffeine dose compared to drinking traditional coffee or tea. It’s also easier to carry around as you can take in the form of pills, gums and gels, and it can improve your athletic performance

Cons: Pure caffeine powder is more potent, increasing the risk of a caffeine overdose or intoxication.

What types of caffeine do I need to look out for?

  • Caffeine pills come in two forms: weight loss supplements (designed to increase fat burn) and athletic enhancers. In both cases, they can increase feelings of alertness and energy.
  • Caffeine anhydrous powder may be the most common form of caffeine anhydrous. But, the FDA advises to avoid pure powdered anhydrous caffeine due to its potency.
  • Other caffeine forms like food product additives, including gums and energy bars to help boost energy and stimulate weight loss. It can also be found in pre-workout supplement powders.

How can I use anhydrous caffeine for weight loss?

Woman measures her weight loss

Caffeine can help to boost weight loss and your physical performance. But how does a caffeine supplement work?

Increase metabolism

The rate at which you burn calories is your resting metabolic rate (RMR). Caffeine can help to raise your RMR by three to 11%, helping to increase your weight loss (when combined with exercise and a healthy diet).

Boosts fat burn

Caffeine can help to stimulate your nervous system by increasing the presence of epinephrine in your bloodstream (as well as raising heat production). 

This sends signals directly to your fat cells, telling them to break down fat and release it into your blood. 

Now, if you do nothing, you’ll struggle to reach your weight loss goals. But, if you make the effort to burn more calories than you consume, you’ll lose weight consistently. And, taking caffeine before you workout can release 30% more stored fat. 

Reduces appetite

During one study exploring caffeine's appetite-reducing effects (on men), caffeine enabled them to eat less during meals. So, there is a chance that a moderate dose of caffeine can help you curb your cravings and stay fuller for longer.

How much caffeine should I have?

Woman drinking coffee

The amount of caffeine you can consume will partially depend on your body weight. Usually, dosages are based on 1.4 to .7mg per lb of body weight, which means you can consume 200 to 400mg of caffeine daily.

That said, you should NEVER have more than 400mg of powdered caffeine daily because of the risk of intoxication.

Instead, aim to start small with just 150 to 200mg of caffeine a day (consumed 60 minutes before exercise) and then assess your tolerance or reaction to it. Only increase if you experience no adverse side effects. 

If you are wary for any reason, or you have a medical condition, please consult a healthcare professional before introducing any caffeine supplement.

Here are some tips to support you to do just that…

Adopt healthy eating habits

Focus on whole, nutrient-dense foods such as fruits, vegetables, lean proteins, whole grains, and healthy fats. Monitor portion sizes to avoid overeating.

Exercise regularly

Weave regular exercise into your routine, aiming for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity a week. Choose an activity that makes you feel good, and you can’t lose. Even a little dancing will do.

Drink plenty of water

Stay hydrated throughout the day. Limit consumption of sugary drinks, fruit juices, and energy drinks, as they can affect your health.

Improve sleep hygiene

Why is caffeine a drug? 

Caffeine is considered a drug as it stimulates the central nervous system. Caffeine also meets the criteria that define a drug, by having physiological effects, a tolerance and dependence barrier, altering mental states, a substance that can be abused—and may not be regulated universally.
