What are Nootropics?

What are nootropics? In the quest for enhanced cognitive performance, more and more people are discovering the benefits of natural nootropics. Nootropics, also referred to as ‘smart drugs’ or ‘cognitive enhancers’, are substances that can help you to boost your brain performance. Using the best nootropics can allow you to enhance abilities such as memory, focus, creativity, intelligence, and motivation. With increasing pressure on students, academics, and workers to perform longer and better, the more people tend to resort to smart drugs to be able to cope with these increasing demands. When speaking of the best nootropics, or smart drugs, some people think of stimulant drugs like Ritalin or amphetamine, which are used to boost performance. However, stimulant use comes at the cost of side effects, hangovers, and long-term consequences such as neurological changes and heart problems. That is the reason why we at Sirius only sell natural nootropics – pure nootropics which are made from only natural ingredients, without any negative acute or long-term health consequences. Using natural nootropics allows you to achieve your maximum performance without experiencing a hangover or a “crash” after a study/work session. 

Pure nootropics, natural nootropics, best nootropics – What to look out for when buying Smart Drugs

It is extremely important to look at what exactly you get when buying natural nootropics or pure nootropics, because many sellers use tricks to manipulate customers into buying their products. Some even offer hard stimulants or research chemicals as “best nootropics”, while not properly informing the customer about potential side effects and issues associated with these drugs. This is not the case at We only sell natural nootropics which are safe to use and do not cause harmful side effects. When shopping pure nootropics at, you do not need to worry about long-term outcomes following nootropic use, because we offer some of the best nootropics that are both pure and 100% natural! 

Large assortment of best nootropics at

If you are looking to buy the best nootropics that are currently on the market, then the Sirius online Smartshop is the best place to do so. We only offer smart drugs that are produced by our house-own brands or delivered by trusted suppliers. Keep reading if you want to discover our product range of best nootropics that are both legal and natural!


IQ+ 100% natural brain booster is one of our most popular and best nootropics. It combines pure nootropics like Rhodiola rosea, Bacopa monnieri and Griffonia simplicifolia with L-Theanine and natural caffeine. These are some of the best nootropics known to enhance mood and cognitive functioning. But it is not only the unique effect of each compound that makes IQ+ so great - it is the synergistic effect of them that makes IQ+ one of the best nootropics available in our online smartshop. IQ+ is specifically designed to support and enhance cognitive functions. As all ingredients are natural, IQ+ does not really produce harmful long-term consequences compared to other smart drugs such as Ritalin or amphetamine. 

Open Up pure nootropics 

Open Up is a brand from Sirius that offers all kinds of natural substances to be used as natural nootropics, natural sedatives, or even natural aphrodisiacs. Below you will find the pure nootropics offered by Open Up in our online Smartshop: 

Hydrocotyle (Centella Asiatica) is a plant that grows all around the world but mainly in Asia. Hydrocotyle is used as a tonic (meaning it is taken regularly, for example every day) to enhance cognitive functions, increase the life span (therefore its name “Herb of Long Life”), and even as skin care. Hydrocotyle can be made in a delicious tea with milk, honey, or anything that you prefer!  

Cola Nut is the fruit of the kola tree, which is native to the tropical rainforest of Africa. Cola nut is a natural source of caffeine, colanine and theobromine, and it has been included in the original recipe of the popular soda ‘Coca Cola’ – hence its name. Traditionally, Cola nut is used as an alternative to coffee or as a vitalizing tonic / smart drug. Open Up offers either dried powder of Cola Nut or Cola Nut Capsules, which make it easier to take cola nut on a regular basis. 

Bionix natural nootropics 

Bionix is another brand from Sirius that offers natural nootropics of the highest quality, among other products. All Bionix nootropics are based on the Bionix Phyto-Nutrient blend, which combines caffeine or caffeine-like substances with B-vitamins, citrus aurantium extract, and amino acids. These substances synergistically act together (“entourage effect”) to create the best nootropics that are safe and free from harmful additions. 

Bionix Guru Power contains the previously described Cola Nut. However, because it is blended with other energizing substances (B-vitamins, amino-acids), it provides a synergistic effect that enhances the abilities of the cola nut to give you the natural nootropic you need when you want to be as productive as you can. 

Bionix Brain Power is a mix of precursors for neurotransmitters, which stimulate your brain functions by giving your body the molecules it needs for active and healthy brain functioning. Because of this, Bionix Brain power can also be used as an alternative to party drugs, or it can be used to deal with a hangover after a party. 

Bionix Cocoa Power contains a high concentrated cocoa extract that, just like chocolate, can lift you up when you are down. Many people know that chocolate can have stimulating properties, but this is only true for dark / bitter chocolate that contains a high percentage of cocoa (at least 70%). This is why Bionix cocoa includes an extremely powerful cocoa extract combined with b-vitamins and amino acids to give you the energy you need.

Natural nootropics in capsule form can be swallowed before or after a meal with a glass of water. Pure nootropics that come as full forms or powder can be ingested, made into a tea, or mixed in with a drink. Oftentimes, it is recommended to use your natural nootropic in the morning, so that you can experience the benefits throughout the day.

Attention Deficit Hyperactivity Disorder (ADHD) is a prevalent condition that affects a significant number of individuals globally. Characterized by symptoms like impulsivity, hyperactivity, and inattentiveness, managing ADHD effectively is crucial for enhancing the quality of life of those affected. Usually, hard stimulant drugs like Ritalin or Adderall are prescribed to treat ADHD, however, these medications are associated with negative side effects. In the evolving landscape of ADHD management, the introduction of nootropic supplements has become a topic of interest. Nootropics for ADHD, those that are known to boost mental activity, focus, and cognitive functions, might be a natural alternative to chemical drugs. 

Natural nootropic supplements are interesting ADHD Nootropics due to their organic and natural compositions. They offer a holistic approach, aiming to augment cognitive performance while minimizing potential side effects. It is proposed that natural supplements can provide supportive roles in enhancing focus, mental clarity, and cognitive resilience, factors that are often challenged in individuals with ADHD. However, it’s essential to underscore the importance of a personalized approach. Every individual’s experience with ADHD is unique, hence the response to various nootropic supplements can significantly vary. That’s why it’s very important to discuss ADHD nootropics with your healthcare professional before you take anything. In our quest to offer comprehensive insights, we are committed to elaborating on this intriguing intersection between nootropics and ADHD. An upcoming blog article will delve deeper into the complexities, exploring scientific evidence, potential benefits, and precautions associated with the use of nootropic supplements in managing ADHD.
