Caffeine has been a part of human life for decades. Nowadays, many people find it hard to imagine their morning without a cup of this aromatic drink. There is so much information about caffeine that sometimes it isn’t easy to understand what is true and what is myth and fiction. In this article, we will try to understand the effect of caffeine on the human body, its benefits for us, and how it can help stimulate mental capacity. We encounter caffeine in everyday life, even if we do not think about it – in coffee, tea, chocolate, energy drinks, and dietary supplements. An invigorating effect is the hallmark of caffeine. Still, this substance works more deeply at the physiological level, affecting many body systems: nervous, cardiovascular, respiratory, excretory, and gastrointestinal. To profit only from caffeine, it is important to choose the right dosage. Then, we will only get pleasant bonuses for reduced drowsiness and increased performance.

Highlights

  • Caffeine improves focus and multitasking by stimulating the central nervous system.
  • Bulletproof coffee blends coffee with MCT oil and butter for sustained energy.
  • Nootropic coffee supports memory, focus, and long-term brain health.
  • Mushroom coffee adds antioxidants, doubling coffee’s health-boosting effects.
  • Limit caffeine to 400 mg daily for best balance without negative side effects.

How does caffeine work

Caffeine belongs to the class of alkaloids, and the pharmacological effects of the substance are that it is analeptic, cardiotonic, and psychostimulant. Simply put, it directly affects the lungs, heart, and brain. At the respiratory system level, breathing becomes more frequent and deep. From the gastrointestinal tract, the secretion of the gastric glands is stimulated. In addition, the structure of caffeine directly affects neurotransmitters and some essential hormones. For example, adenosine. This is the first neurotransmitter worth mentioning. The mechanism of action of caffeine is directly related to it. It is involved in the body’s biochemical processes and is triggered by fatigue; its concentration increases with prolonged wakefulness and decreases after sleep. Due to the similarity of their molecular structure, caffeine comes into play. It turns off this reaction, blocking adenosine receptors in the brain and other organs.

Why do biohackers love coffee

Biohackers pay special attention to this stimulant precisely because it improves concentration and gives the body energy. When we drink it, we feel an increase in mental and physical performance, the time of our reactions to the environment is reduced, and we become faster, more focused, and more cheerful.

Boosting energy & mental clarity

Caffeine increases the body’s production of adrenaline. Due to this, the blood flow to the brain increases. This helps us to react quickly, think well, and act actively physically.

There is evidence that the concentration of adrenaline in young people after taking caffeine reaches 500%. We believe and act faster because caffeine begins to act on stimulating hormones till the caffeine half-life. At the same time, the adrenaline level increases. It activates the production of another hormone, cortisol, by stimulating the adrenal glands, which are also constantly involved in stress reactions. This enhances the effect of caffeine itself and increases a person’s resistance to stress in general. In normal mode, it is mainly produced in the morning, giving our body the command to achieve life goals.

However, when the natural peak of cortisol content declines, it can be supported by caffeine. After noon, cortisol goes to rest, so a cup of coffee raises our energy. You can especially notice this mechanism of action when you are doing sports. Cortisol production gets higher after taking caffeine and training. With intellectual activity, the increase in cortisol concentration will be less.

Enhancing focus & productivity

Caffeine also stimulates the central nervous system, speeding up the transmission of signals between neurons. This leads to a faster response to external stimuli and improved coordination between different brain parts. As a result, a person becomes more focused and better at multitasking.

Caffeine helps increase work capacity and maintain focus by producing testosterone after its use. This hormone reduces fatigue and can increase motivation for action. 

Studies have shown that caffeine affects testosterone growth. This effect is greater during sports when the substance is taken before training. Caffeine also affects physical endurance during strength and anaerobic exercises. This effect is well-known and is widely used in pre-workout complexes.

Improving mood & dopamine regulation

Caffeine affects your good mood. And not only when you do it during a catch-up with friends. It stimulates the release of dopamine, a neurotransmitter linked to the brain’s pleasure centers. This chemical process directly affects a person’s motivation: it increases the desire to complete tasks, solve problems, and overcome difficulties. 

People are more likely to perceive routine tasks with tremendous enthusiasm, which can improve productivity significantly when motivation naturally declines. Thanks to this, you can feel a surge of positivity after a couple of sips. In addition, antioxidants contained in caffeine fight oxidative stress. It is this that causes anxiety and depression. So, thanks to drinking drinks containing it, you will be able to regulate your mental state better.

Types of biohacked coffee

Biohackers have taken the morning cup of coffee ritual to a whole new level. To enhance the drink’s properties and valuable qualities, they have learned to mix and improve its composition by adding different ingredients that seem impossible to imagine. We will talk about several of the most popular types of coffee and drinks based on them that are conquering the world and becoming part of global trends.

Bulletproof coffee

Dave Asprey, the creator of the famous Bulletproof Coffee, is a true visionary in the world of biohacking. A trip to Tibet led the IT engineer into the coffee business, and coffee with butter became a trendy drink used by world celebrities.

According to legend, the idea for “Bulletproof” came to Asprey in 2004 during a trip to Tibet. After drinking national tea with yak butter, Dave felt an unprecedented surge of energy. He decided to create his own revolutionary product, but based on coffee. It took almost six years to develop, and in 2009, he first published the recipe on his blog. Asprey’s original recipe consists of signature coffee, ghee from lactose-free New Zealand cows, and Brain Octane C8 MCT oil. The coffee must be prepared and blended with the oils. A capsule version of “Bulletproof” is also available, containing all the necessary additives. MCT (Medium Chain Triglycerides) are saturated fats derived from coconut or palm oil. The product appeared in the 1950s and was initially intended for patients with metabolic disorders. Unlike long-chain fish fats and other vegetable oils, MCTs are absorbed faster and saturate the body with energy. 

Brain Octane C8 MCT oil consists entirely of caprylic (C8) acid. Dave Asprey claims it maintains energy (especially when combined with caffeine), speeds metabolism and improves cognitive function. He is confident that Bulletproof and other biohacking techniques increased his IQ by more than 20 points.

Nootropic-infused coffee

Nootropic coffee, or smart coffee, amplifies the stimulating effects of a regular cup of coffee. Nootropics, also known as “smart drugs,” are dietary supplements that help support certain brain functions, including memory, mental speed, and focus.

The main benefit of nootropic coffee is its ability to reduce brain fog and clear your mind, helping you achieve your goals. It can also help improve your overall mood and temperament, especially if you feel overwhelmed or tired. Some nootropic ingredients also have long-term cognitive benefits, making this supplement ideal for overall brain health.

Mushroom coffee

Maybe it’s the first time you’ve heard about this combo, but mushroom coffee is increasingly getting the minds of biohackers. It is a mixture of regular coffee and extracts of various dried mushrooms, such as Chaga, hedgehog mushroom, reishi, and others, which are considered medicinal in non-traditional medicine in different countries. Sometimes, along with the “medicinal” mushrooms, regular edible ones are added to the coffee mixture: honey mushrooms or oyster mushrooms. Some varieties of mushroom coffee contain only one type of them, while others may include several. This drink is available in capsules and powder form. It can be instant or natural and brewed like regular coffee – you can also make an americano, latte, or cappuccino. 

One of the main advantages of this product is its high concentration of antioxidants.

Scientific research has shown that a regular cup of coffee can contain more antioxidants that fight diseases and signs of aging than cocoa, green, black, or herbal tea. Mushrooms also contain these substances, especially a lot of glutathione and ergothioneine. This means one cup of mushroom coffee includes a double dose of antioxidants!

The mushrooms are dried, crushed, and extracted to prepare the drink. The resulting extract and particles of the dried mushroom are added to coffee, usually in a 1:1 ratio. The drink tastes like regular coffee, but some people feel a nutty or earthy flavor.

Cold brew for sustained energy

Cold brew is black coffee brewed with cold water for 8-24 hours. The result is a fresh, invigorating drink with reduced acidity and bitterness. Cold-brew coffee entered pop culture in the 1960s. The drink was discovered by American entrepreneur Todd Simpson during an expedition to Peru. Since coffee is brewed with cold water for quite a long time, it slows down the extraction of various compounds from ground beans. The taste of such a product is softer, and the acidity level of cold brew coffee is 66% lower than that of its hot counterpart; it is also less bitter. Therefore, it is recommended for people with a sensitive stomach or acid reflux – it will be easier for the body to accept such a drink.

Decaf & low-caffeine options for better sleep balance

This product has been processed to remove caffeine in one way or another. Up to 99.9% of the original caffeine can be removed from coffee, reducing the average 100 mg to 3 mg in a cup in terms of pure substance. This option is worth considering for those who have contraindications to regular coffee or a desire to drink coffee before bed, after which problems with insomnia arise.

Decaf still contains a small amount of caffeine, which varies depending on the country of origin. In Europe, the caffeine content in a decaffeinated drink should not exceed 0.1%, and in the USA – 3%. The calculation is not based on weight but depends on the original caffeine level in the type of beans. For example, Arabica contains 1-1.5 grams of caffeine per 100 grams of beans. Robusta has a higher caffeine content – about 2-3 grams per 100 grams of beans, so decaffeinated robusta will still have a little more. Although such coffee retains its taste and is an alternative for those who like to drink a cup before bed, it has very few beneficial properties of caffeine.

How to biohack your coffee 

Okay, now it’s more understandable with types of coffee and new trends in this field. Coffee is a good time spender and a real biohacking secret. Then, how do you get the most out of your morning drink, and how much caffeine should you consume to maintain balance and not get side effects?

Extract the most caffeine from coffee

Now that we have learned a little more about coffee, its possibilities for the body, and its types, let’s try to figure out how to get the most caffeine out of our drink for the maximum effect. 

Make it hot

If it’s not cold brew, adding as much heat as possible when brewing is better. This is how you will increase the percentage of caffeine in the drink. The water for brewing should be close to boiling and you will get the perfect coffee. 

Choose robusta

Compared to Arabica, robusta contains more caffeine, contributing to a better invigorating effect. At the same time, it has a more bitter, pronounced taste. If you like Arabica’s sour and smooth taste, you can mix the two types and get both taste and additional strength. 

Fresh grind

Use beans that have just been ground. This way, the coffee will retain the most significant number of valuable elements and the percentage of caffeine. In addition, the taste of such a drink is much brighter. 

Let it rest 

Even though it is better to brew coffee with very hot water, it is still worth letting it cool down a little and steep. This is how the drink will give off the largest amount of caffeine.

Don’t skimp on the brewing

As trite as it may seem, we sometimes add too little coffee to get the desired effect. So don’t be afraid to add more; a cup of drink will invigorate you. Don’t forget that too much brewing can make it very bitter.

Take some chill

If you want to get the maximum effect from caffeine and be more energetic, then you should opt for cold brew. Since this method of brewing the drink is steeped for a long time, the concentration of caffeine in it is also higher. Accordingly, such a drink will invigorate you better.

How much coffee should you drink

The amount of caffeine consumed is strictly individual; it is impossible to say precisely how much coffee a certain person needs, but it is still better to start with small doses and then move on to larger ones. Our coffee tolerance is high, so you will likely not limit yourself to one cup. However, experts advise people not to consume more than 400 mg of coffee daily (4-5 cups). Gradually increase the amount of the product consumed. Try drinking one cup of coffee; if it’s not enough, drink another. Most likely, this will invigorate and add a sufficient amount of focus and caffeine to the body.

Arabica or Robusta

Arabica and Robusta are the two main types of coffee. They differ in appearance and taste. Arabica is considered more popular. There are many reasons for this. The main one is that Arabica simply tastes better. It has less caffeine than Robusta. This type has a lot of lipids and sugars, which make the taste intense and acidic. In a specific Arabica variety, you can feel the sweetness of berries, the acidity of citrus fruits, and the aroma of flowers and nuts. 

Robusta has more caffeine, chlorogenic acid, lipids, and sugars. This makes it a good energy drink, but caffeine also gives coffee bitterness and a heavy aroma. The taste of Robusta is tart and flat. It is simply impossible to achieve shades from it like Arabica. There is no better type, you just have to choose the one you like most. For the best effect and taste of the drink, try mixing these two types.

What are the risks of caffeine?

Although caffeine is good for the body, you shouldn’t drink only coffee all day. The fact is that excessive coffee consumption has several side effects. 

  • Insomnia: Too much caffeine, especially in the evening, can disrupt sleep, leading to chronic sleep deprivation and decreased overall productivity. 
  • Anxiety and nervousness: For some people, even a moderate dose of caffeine can cause anxiety or panic attacks. 
  • Caffeine drug: Regular caffeine consumption can cause physical and psychological dependence, making a person dependent on a daily dose of coffee. So, be aware of the addiction possibility. 
  • Blood pressure problems: Caffeine can increase blood pressure, which is unfavorable for people with hypertension.

Coffee alternatives for biohackers

We’ve sorted out how to extract the significant benefits from caffeine. Let’s talk about what to do if you’re not a coffee fan but want to get the caffeine effect. What alternatives do we have from the usual cup of coffee?

Matcha & green tea

Matcha and green tea differ in how the leaves are grown and processed. For example, unlike traditional green tea, matcha involves covering the tea bushes with a cloth before picking to create shade. The leaves for matcha are hand-picked, lightly steamed to stop fermentation, then dried and refrigerated. The dried leaves are then ground into a fine powder. With matcha, you consume the entire tea leaf.

Matcha usually has a distinct earthy and slightly bitter taste compared to traditional green tea. So many matcha drinks are milk-based, which masks the flavor. Most drinkers prefer these over the conventional water-only drink. The flavor of green tea can vary greatly depending on the variety and region but is generally more subtle and delicate. Matcha increases energy and stamina. While green tea invigorates us with the caffeine it contains, matcha boosts energy thanks to the same L-Theanine. The energetic effect of a cup of matcha can last up to six hours, and it is not accompanied by nervousness or hypertension.

Matcha also usually contains more caffeine than regular green tea since you consume the entire tea leaf. And while green tea does contain caffeine, the levels are generally lower. 100 ml of matcha includes an average of 64 mg of caffeine, while green tea contains 30–50 mg per 250 ml cup.

Yerba mate 

This is a tonic drink made from the leaves of the Paraguayan holly. Yerba Mate gives your body a strong energy boost and helps increase your endurance. It has been shown to lower cholesterol, protect the liver, stimulate the central nervous system, improve kidney function, and benefit the cardiovascular system. It is also used for weight loss and obesity treatment. 

Yerba Mate also protects DNA from oxidation, has high antioxidant activity, and is associated with the prevention and treatment of cancer. The drink has a moderate dose of caffeine, which acts more gently and for a longer time. It improves concentration and energy without sudden surges, making it a great option for biohackers who want to avoid coffee’s “crash” effect.

Chaga & reishi mushroom elixirs

Birch mushroom Chaga improves metabolism and restores the immune and nervous systems. It is necessary for the prevention of anemia, obesity, hypertension, atherosclerosis, and gastritis. It contains high concentrations of melanin, betulin, and other biologically active substances that neutralize the harmful effects of free radicals. 

Reishi is considered both a tonic and adaptogenic drug. As an energy boost, it strengthens the body, and as an adaptogen, it helps to adapt to stress. Chaga has unique immunomodulatory properties. Due to its high content of polysaccharides and triterpene compounds, it stimulates the production of T-cells, NK cells, and other essential elements of the immune system. This helps to effectively resist infections, viruses, and other pathogens. 

When Chaga and Reishi act together, their healing capabilities increase often. The antioxidant potential of Chaga enhances the anti-inflammatory and antiviral effect of Reishi. The immunostimulating properties of Reishi, in turn, increase the body’s overall resistance to various diseases. In addition, these mushrooms have adaptogenic and tonic properties, helping to cope with stress, increase performance, and improve sleep quality.

Chicory & dandelion root coffee

These roots are an excellent substitute for regular coffee. Both chicory and dandelion have blood-purifying properties, help detoxify the body, and stimulate digestion. They are also helpful for diabetics, as they do not sharply increase insulin. 

Among natural energy drinks, chicory ranks first in its effectiveness. Doctors recommend drinking it in cases where coffee is contraindicated for health reasons, but you really want to improve your mood, increase your performance, and cope with a loss of strength. The drink, taken on an empty stomach, dulls the feeling of hunger and significantly reduces appetite. It is useful for weight loss, dietary nutrition, or the prevention of excess weight.

Coffee from roasted Dandelion roots can be drunk by those who are contraindicated with caffeine. Dandelion coffee is a choleretic, diuretic, anti-inflammatory, antiviral, and antipyretic agent.

High-fat coffee biohack

High-fat coffee is coffee with added oils like MCT or butter. This drink maintains energy and focus thanks to ketones quickly absorbed by the body. It is ideal for those who watch their diet or practice intermittent fasting. You can try this biohacking by putting a small piece of butter into your coffee cup and trying to notice if there is any difference. 

Caffeine stimulates thermogenesis, the process by which the body generates heat by burning calories, and butter helps to saturate the body so that you don’t want to eat more. This may speed up metabolism and improve fat burning, especially when fasting.

Let’s sum up

For biohackers, caffeine is a powerful tool for improving cognitive functions, particularly the ability to concentrate and speed up reactions. Also, consuming before training can increase physical endurance and performance. It’s a great and healthy stimulant that can develop your metabolism and help increase your productivity. Due to the effect on human hormones, it activates important processes: 

  • Focusing attention;
  • Productivity;
  • Improvement of mental abilities ;
  • Activation of the hormone of happiness.

Talking about new tendencies in the coffee market that are popular among biohackers, we should talk about Bulletproof Coffee, which combines coffee with butter and MCT oil to increase energy and maintain concentration throughout the day. Also popular is nootropic coffee, which enhances the effect of caffeine with additives to improve cognitive functions, and mushroom coffee, which is rich in antioxidants. Such additives to the main caffeine activate energy and improve concentration. Judging by its popularity among biohackers, it works. 

So, a few cups of coffee will make our life better. However, it is important to maintain a balance and avoid this product, as you can increase anxiety or cause insomnia by drinking more than your norm. If coffee is not your favorite product, try alternative drinks. It can be green tea or matcha, drinks made from Chaga and reishi mushrooms, or yerba mate. You can also pay attention to more classic and familiar products like chicory and dandelion root. They also increase vigor and have a positive effect on the health of the body.
