Caffeine in capsules? It seems a different presentation for this substance, after all, when we think of caffeine the first word that comes to the mind is: coffee. But it is not only in this drink that we find it.

According to the Food and Drug Administration, about 90% of the world’s population ingests some kind of  caffeine .

It is a stimulant substance of the central nervous system found in seeds, fruits or leaves, from where it is extracted and transformed into food or drinks like the known coffee.

It is also present in black, mate or green tea, guarana, chocolate, cola drinks and energy drinks.

Industrially, it is marketed in tablet, tablet, powder, gel, liquid, capsule or bar.

The capsules represent an interesting way to consume a precise dose and a more pure formulation, so let’s unravel its mysteries.

Caffeine in capsules: what’s the use?


This chemical compound acts in the body allowing stimulating substances to be produced and released, having energetic action.

In addition to the mental stimulant, it allows the body to be more disposed, performing physical activities like running or power competitions in a more intense and lasting way.

Combating fatigue and increasing concentration also has positive effects.

Studies show that the consumption of its capsules is able to improve endurance performance during exercise, since it saves muscle glycogen, favouring the results.

However, according to the National Sanitary Surveillance Agency (ANVISA), the caffeine supplement in capsules is a product intended exclusively for athletes.

Its purpose is to increase endurance in long-term exercises for some specific cases, preferably with the guidance of a professional.

Caffeine in capsules helps to define the body: myth or truth?

This substance is considered thermogenic, that is, it requires more energy from the body to be digested, subtly increasing the body’s metabolism.

In addition, it is able to stimulate lipolysis, causing the body to use fat more efficiently as a source of energy in exercise rather than muscle glycogen.

In this sense, when consumed frequently would be able to consume the fat reserve of adipose tissue.

On the other hand, scientific research indicates that the ergogenic effects of exercise disappear when the capsules are used when compared to individuals who do not use them, even in cases of protein supplementation.

That is, this supplement is able to improve performance during exercise and may aid in reducing fat accumulation, but may not promote hypertrophy.

Therefore, if the individual already has a muscle mass constituted, the caffeine in capsules can rather assist in the definition of muscle.

If your goal is to lose weight and gain lean body mass, ask your dietician about the food plan and any supplements that are most suitable.

This recommendation is valid for all practitioners of physical activity, regardless of whether they practice it regularly or sporadically for the purpose of physical conditioning, aesthetics, rehabilitation, physical fitness or recreation.

The capsules are totally contraindicated for children and pregnant women during the breastfeeding phase.

The effects are very variable, but the health risks are tachycardia or palpitations, insomnia, anxiety and loss of appetite.

There is a large variation in the amount tolerated by each individual, so it is important to understand the sensitivity of each individual.

Those who already suffer from insomnia, for example, should avoid maximising their consumption, especially after 6 pm.

It also has a diuretic effect, which can increase the frequency of urination, cause dehydration and renal overload in the long term.

Those who do not swallow it can feel the negative effects even at low dosage.

Age, weight, use of medications and health problems can make the individual more susceptible.

Health risks usually appear when products are eaten improperly, but be aware of the signs of your body.

Recommendations on how and when to consume

rule for healthy

The daily recommendation should be based on the needs of the athlete, but as a general rule for healthy individuals should not exceed 400mg of caffeine/day. For adolescents, this amount is even lower, of 100mg / day.

Supplements for athletes provide between 210 and 420mg per serving. Therefore the idea is to consume 1 to 2 pre-exercise capsules if you do not use other beverages based on this substance.

As their maximum action power in the body is between 30 and 60 minutes after consumption, the indication is to respect this period prior to exercise.

The first positive point of caffeine in capsules is the practicality. Since 2010 the product can be marketed in food supplement stores, which were previously banned.

The substance in the capsule can have potent effects on athletes, being a great option since it has a more pure formulation.

Moreover, when consumed encapsulated exactly the amount/portion is known, being easier to avoid overdosage and side effects.

In food or home-made beverages, this count is much more complex, since there is a great variation.

For example, each cup of coffee (150ml) has 60 to 150mg of caffeine, so the maximum dose may be 6.5 to 2.5 cups/day. For energetics the rule is similar, ranging from 80 to 160mg / can.

In these cases, it would be necessary to read product labels and have much more caring attitudes.
