15 - 05 - 2018

You can find it in your daily cup of coffee, many use it during exercise, and some can't  even function without it. What is caffeine and above all: what does it do to your body? First let's take a scientific look at this well-known substance!

The science

Caffeine is part of to the group of the alkaloids. Other known substances in this category are morphine, cocaine, ephedrine, ... This type of molecule usually has a strong physiological or pharmacological effect on the human body. Originally, they are usually produced by plants, where it acts as a protective mechanism: the plants become toxic to animals or insects.

Caffeine is produced in the coffee bean, tea leaves and in the lesser known guarana berry. Even our favorite cocoa bean contains caffeine. Nowadays the molecule can also be synthetically produced. It is a white powder that tastes very bitter.

The half-life of caffeine is approximately 5 hours. In practical terms, this means that after drinking your cup of coffee in the morning, you still have half the amount of caffeine in your body in the afternoon.

The effects

Caffeine reduces fatigue. That's why we all drink coffee on a massive scale in the morning to get through the day. However, it also improves response time, concentration and coordination. Caffeine also increases your basal metabolism. This is the energy that your body consumes by simply "being", so your energy consumption at rest. That is why caffeine is also one of the few substances that can really help you lose kilos. Do not get carried away: the extra energy that you consume by taking caffeine is estimated at a maximum of 200 kcal a day! That means you can lose 1 kg of fat in about 40 days. It is important that you do not compensate for that 200 kcal with an extra biscuit with all that coffee of course.


Hundreds of studies have already been performed to the ideal dose of caffeine for athletes. And each study has a different result, varying between 3 mg and up to even 9 mg of caffeine per kilogram of body weight. What these values always forget to mention is the personal experience. What is the advantage of an ideal dose of 450 mg caffeine if you become extremely nervous and maybe even get palpitations from it? We at Sanas are certainly not fans of huge doses of caffeine.

Caffeine shots

In our Energy category we have 2 products that contain a guarana extract. This is a natural form of caffeine from the Guarana berry (Paullinia cupana Kunth.) which is grown mainly in South America. The plant contains more caffeine than the coffee bean, but this molecule is released somewhat slower than when drinking coffee. This gives you a lower chance of feeling nervous hunted or having palpitations.

Guaranol Mega Forte contains 160 mg of caffeine. This corresponds to 3 cups of coffee. For most of us this already gives a considerable effect to be able to go all the way! Guaramint is then again ideal for people who do not drink coffee and are sensitive to caffeine. It contains 80 mg of caffeine and will give them the necessary boost. Guaramint can also be used to refuel during longer sessions.

Both shots contain no less than 500 mg of taurine. In combination with the caffeine this provides an extra focus. Especially the slightly lower dosed Guaramint is ideal for a student who can use something extra to go through those last chapters.

So: could you use an extra energy boost? Then know that besides your cup of coffee there are other possibilities that can help you to achieve your goals!
