Piriste is based on everyone’s favorite caffeine, the most commonly used nootropic in the world. It is known and used for its stimulating, energizing effects and increased vigilance. The effect is particularly noticeable when the level of activity is otherwise low (early in the morning, at night, sick or sleepy). However, caffeine has been shown to improve cognitive functions in healthy subjects also in optimum working conditions.

The effects of caffeine have been studied relatively broadly. It has been shown that caffeine has clear beneficial effects for both simple and complex tasks requiring attention. 200 mg dose of caffeine can improve alertness, reaction time and attention without adverse effects on fine motoric functions (a study by US Marine Corps).


Piriste includes one of the world’s most studied and used nootropic combinations, theanine and caffeine. Theanine prevents the negative side effects of caffeine, such as nervousness, restlessness and tension. Together, caffeine and theanine provide even more energy than just caffeine. Caffeine stimulates the central nervous system and the release of endogenous neurotransmitters. Caffeine can easily be over-stimulating and cause nervousness. By increasing the GABA concentration theanine helps the central nervous system relax and prevents the negative effects of caffeine.

Theanine is an amino acid found in green tea that relaxes the body and mind, reduces physical and mental stress, improves cognition and enhances synergism with caffeine.


Piriste contains guarana seed extract which increases visibility and clarity and enhances the effect of nootropic compounds, ie caffeine and theanine. It’s worth noting that Virta includes only pure guarana seed extract which is far more potent and also far more expensive than generic guarana products that also include leaves and stems.

Guarana (Paullinia cupana) is a small shrub or wood plant originating in South America. Indigenous peoples have used it to revitalize and eliminate hunger. Guarana is a well-known and completely natural source of caffeine, theobromine and theophylline. These energizing compounds and the guarana tannins have made the plant popular throughout the world.

Guarana seeds contain four times caffeine compared to coffee beans (4-8% vs. coffee 1-2.5%). Guarana raises cognitive alertness very quickly. The use of guarana as a dietary supplement is characterized by increased vigilance, increased metabolism and increased self-confidence.


Piriste contains vitamin B6 as it increases mental performance and balances mood. We use high-quality pyridoxal-5-phosphate (P-5-P), a metabolically active form of vitamin B6.

B6 is a water-soluble vitamin that should be obtained daily. It is found in many common foods such as meat and certain vegetables, but vitamin B6 loses its power when cooking, which is why it is useful to ensure adequate intake by using it as a supplement. However, excessive vitamin B6 intake may be harmful to the nerve cells, so dietary supplements with a high concentration of B6 are not recommended. The amount of B6 in Piriste is in the safe range even in the maximum suggested daily dosage.

Vitamin B6 is essential for the development and maintenance of cognitive functions. It is involved in the formation of neurotransmitters and regulates the concentration of homocysteine ​​in the blood. Vitamin B6 is a proven supporter of mental health. It is often used in the treatment of depression, fatigue and headaches.


We use cobalamin (vitamin B12) in Piriste as it enhances vigilance, memory and concentration. In addition, cobalamin has an energizing effect. We have chosen the high quality methylcobalamin, which is able to penetrate the blood-brain barrier and thus provide the benefits of cobalamin to the brain’s nervous system.

Vitamin B12 has been known for more than 50 years as a chronic fatigue treatment. It helps the body to produce and maintain red blood cells, nerve cells and DNA. Vitamin B12 is essential for normal functioning of the nervous system. B12 deficiency can cause anemia, fatigue, muscle weakness, lack of appetite, and cognitive problems.

Vitamin B12 users often report improved quality of sleep as well as reduced stress, nervousness and restlessness.


We use piperine in almost every product, including Piriste. And for good reason: piperine improves the bioavailability of other compounds, i.e. increases their level in the body after ingestion.

Piperine is black pepper in condensed form. Piperine is found in several supplements, herbal products, and some medicines to improve the bioavailability of other compounds. Piperine increases bioavailability in at least two ways: slowing down the metabolism of the compounds through liver metabolism and slowing down glucuronidation, which is also the metabolism of foreign molecules in the body that is extrinsic in the body. For example piperine raises the curcuminoid content of turmeric in the body more than ten times that of the turmeric which is consumed without piperine.

About Piriste

Piriste is a dietary supplement that increases endurance and alertness for about four hours. By delivering energy in a balanced way, Piriste creates an ideal state of mind for physically or mentally demanding tasks.

The formulation of Piriste is designed to make you last longer and deliver more, whatever it is you want to achieve. Very importantly, Piriste prevents the abrupt energy level decline and fatigue sensation typically experienced after the use of high-caffeine products. Piriste increases alertness evenly and comfortably. It maximizes the practical positive effects of coffee but avoids its typical, unwanted side effects.

Piriste is suitable for anyone wanting to get more stuff done, be it students, high-performance workers or athletes. We have made sure Piriste is not a “pre-workout” pill which will not allow clear thinking anymore. Piriste will raise your alertness noticeably but in a balanced way that allows you to also focus on mentally demanding or precision-requiring tasks.

What makes that possible? Piriste includes a cleverly engineered combination of ingredients that together are literally more than the sum of its parts. Theanine is a natural amino acid found in green tea that works synergistically with caffeine. The energy and motivation from the caffeine is harnessed and smoothed over with theanine. This combination improves concentration and performance in demanding tasks as proven by several clinical studies. Theanine also alleviates the side effects of caffeine such as the feeling of fatigue after caffeine runs out and the sensation of nervousness in sensitive people or with high doses of caffeine.

Guarana is high in caffeine but also inhibits anxiolytic and antioxidant qualities. Guarana raises cognitive alertness very quickly. Piriste includes only pure guarana seed extract which is far more potent and also far more expensive than generic guarana products that also include leaves and stems. Vitamin B6 and B12 support cognitive alertness and against fatigue while piperine enhances the bioavailability of all the ingredients.

Piriste was field-tested in Finland, with the highest consumption of caffeine in the world. That is the ultimate benchmark for Piriste.
