Sparta Nutrition Kraken is a pre-workout supplement with L-Citrulline, Beta-Alanine, HydroMax® Glycerol Powder, Taurine, N-Acetyl-L-Tyrosine, Vaso-6™, Theacrine, Caffeine Anhydrous, Theobromine, N-Methyl L-Tyramine Hydrochloride, Cocoabuterol® (Cocoa Extract Seed) and Vitamin B3 and B12. By boosting nitric oxide production and stimulating the nervous system, the formulation improves the body’s physical performance during exercise.

Endurance and reduced fatigue
is involved in the urea cycle which leads to the removal of ammonia that causes mental and physical fatigue. Supplementing with this substance may therefore prevent fatigue and help you perform a workout without the urge to reduce exercise intensity.

Increased muscle activity leads to the production of lactic acid which lowers the pH within the muscles and impairs the conduction of nerve impulses and muscle contractility. Beta-Alanine is converted into carnosine which reduces negative effects of lactic acid and that is why your muscles may work longer and more effectively. An increase in muscle endurance allows you to add more reps to each working set.

A state of mind, which allows you to be fully focused and engaged in a particular task, increases your precision and overall efficiency in every field, including sport. Supplementing with taurine before and after a workout may enhance focus during a workout. N-Acetyl-L-Tyrosine from the supplement increases mental alertness and focus and improves training intensity by delaying the onset of mental and physical fatigue.

Muscle pump
An increase in nitric oxide (NO) blood levels causes the relaxation of vascular endothelium. This is very important for enhancing oxygen and nutrient supply to muscles and consequently improving training performance. The supplement contains L-citrulline, which is a substrate for nitric oxide synthesis, and Vaso-6™, a natural, patented ingredient that increases nitric oxide production and blood flow through the working muscles.

HydroMax® is glycerol powder which contains up to 65% of glycerol. Adequate hydration levels of muscle cells aren’t only important for their size but also muscle fibre contractions. Glycerol increases blood volume and improves circulation in the working muscles. The most important benefit for bodybuilders is that the substance can bind water and cause its retention. It also enhances muscle pump.

Energy and stimulation
Your workout won’t have good results if you do not maintain your intensity or manage training loads. We don’t always feel up to doing a workout. After a hard day or sleepless night, we often lack energy to achieve all training goals. At such moments, we use substances or supplements which deliver a huge dose of energy and effectively stimulate the body.

Caffeine anhydrous is characterised by better absorption than the simple form of this substance. Caffeine is a substance with stimulant properties whose mechanism of action is based on the antagonism of adenosine receptors. Supplemented before a planned workout, it helps reduce fatigue and increase training intensity and exercise tolerance. Theobromine, found in cocoa bean extract, has similar effects to caffeine, but they are milder and more lasting.

The addition of theacrine to this supplement reduces the likelihood of overstimulation of the nervous system caused by caffeine and allows you to enjoy all benefits of taking this stimulant.

N-Methyl-L-Thyramine Hydrochloride boosts the secretion of catecholamines such as adrenaline, noradrenaline and dopamine and may therefore contribute to increasing energy levels and activating beta-2 adrenergic receptors, thereby increasing cGMP and cAMP levels. Higher cAMP levels promote body fat reduction by increasing the basal metabolic rate (BMR) and oxidation of fatty acids which provide energy during exercise.

Cocoabuterol® is a cocoa bean extract which is standardised to contain 50% cocoa alkaloids and is rich in polyphenols. The manufacturer of this formula enumarates many benefits of its intake, including body fat reduction, muscle growth, better muscle endurance and strength and antioxidant effects. Cocoabuterol® is also abundant in theobromine discussed above.

Vitamin B3 and B12 are involved in energy metabolism and beneficially influence the nervous system and mental activity by improving the overall mental health and promoting well-being.

To sum up, Sparta Nutrition Kraken is a dietary supplement which is recommended both to professional and amateur athletes who want to increase training effectiveness and maximise training benefits. The product is also recommended to individuals with a drop in energy levels and lack of motivation for doing regular workouts and pursuing training goals.

Vitamin B3


Vitamin B3 (vitamin PP, niacin, nicotinic acid, nicotinamide) is niacinamide niacin. It is used in interaction with vitamins B1, B2 and B6 in the synthesis of hormones during lactation. It provides proper functioning of the brain and nervous system. It is helpful in inflammatory conditions of the skin. Required for synthesis of sex hormone, estrogen, testosterone, cortisone, and insulin. It does not lose its properties in the manufacturing and storage. The source of acquiring vitamins PP are both products of animal origin (the lean meat, eggs, fish) and vegetable origin (dates, figs, hazelnuts, plums).
Dosage: 2-12 mg / day for children, 14 mg / day for women, 16 mg / day for men and 17-18 mg / day for pregnant or nursing women.


Vitamin B12 (Cobalamin)


Vitamin B12 (cobalamin, cyanocobalamin) is a vitamin soluble in liquids. Participates in the production of red blood cells and is essential in the absorption of iron by the body. It calming effect, a positive effect on concentration and memory. Intensifies its action in cooperation with folic acid (vitamin M). Usually occurs in animal products, fish and dairy products. It contains trace elements.
Vitamin B12 deficiency can lead to pernicious anaemia, general and immunity weakness, inhibiting of growth and damage to the myelin sheath of nerves.




What is L-Citrulline?

L-Citrulline is an α-amino acid, ornithine derivative. It was isolated for the first time from watermelon and this is how it gained its name, as citrullus in Latin means watermelon. Citrulline takes part in oxygen processes of energy production during effort, thanks to which it is especially attractive for sportsmen of endurance disciplines. It also takes part in urea cycle, also known as the Ornithine cycle, thanks to which it helps to get rid of excessive amounts of ammonia from the organism.

It converts to l-arginine in kidneys and scientific studies suggest that is increases its level even more effectively than in case of sole arginine. Moreover, the increase of arginine level resulting from citrulline supply is longer and more stable. Thanks to this, it contributes to the increase of nitric oxide and widening of blood vessel lumen. This property makes citrulline useful in preventing cardiological incidents. The positive influence on the circulatory system is also used in case of erection disorders, as increased nitric oxide may initiate more effective blood flow to sex organs.

L-Citrulline is contained in the composition of many pre-workout supplements and NO-boosters directed at the improvement of sports abilities of the organism, which may be found in the offer of




Beta-alanine (β-alanine) is a β-amino acid (the same group to which the I-alanine belongs, but with different chemistries). In combination with histidine, it forms β-alanyl-L-histidine (carnosine) - a antioxidant, chelating and buffering compound. Carnosine reduces the level of hydrogen ions in the cell and allows to extend the physical performance and endurance, it affects biological recovery after exercise. Beta-alanine is available in the form of single component and advanced amino-acid supplements, creatine stacks and nitrogen boosters.




Glycerol (glycerine, 1,2,3-propanetriol) simplest tricarboxylic alcohol, used in the manufacture of medicines (as a filler), cosmetics and food industry. Used in higher doses affect water and electrolyte balance of the body, increase exercise capacity and extend the duration of exercise in various sports. In the sports supplementation used for hydration of the muscle cells to increase the volume of muscle during exercise. Glycerol (sugar alcohol) increases the ability to hydrate the phosphorus muscle cells, allows better nutrition and increasing the volume. It also has an impact on water and electrolyte balance and energy production. By oral ingestion does not change the glycemic profile of blood. It comes in the form of solid and liquid (glycerine), as mono-preparation supplement or an ingredient of pre- and post-workout supplements (creatine stacks nitrogen boosters).
Dosage: 5-10 g per day dissolved in water, in the time before and after exercise. Beginning of application should be started on low doses and gradually reach the maximum, commonly used in sports supplementation dose.



Taurine – non-protein amino acid containing sulphur, which is synthesized in the body from methionine and cysteine, present in sufficient amount in human or animal body (in the brain, heart and skeletal), although in some cases must be supplemented. Significantly affects the calcium content in the cells and stabilizes the water and electrolyte balance and maintains acid-base balance. Takes part in the synthesis of bile acids. In the body acts as a neurotransmitter and neuromodulator. It is an insulin-mimetic improving insulin metabolism, responsible for transport of nutrients (such as amino acids, glucose, creatine) to the cells and muscle tissue. These properties determine that it is a valued mono-preparation supplement and valuable addition to creatine and amino acid supplements, recommended for psycho-pchysically active people and athletes and other competitive sportsmen in pre- and post-workout periods.
Dosage: 3 grams per day.




N-acetyl-L-tyrosine - acetylated form of tyrosine (an endogenous amino acid) improves the solubility and bioavailability of active ingredients. It can be used in lower doses than those taken as free tyrosine. It has a higher availability to the nerve tissue, reduces the feeling of fatigue, improves the exercise capacity psycho (psychostimulant), and, it is a additive to thermogenic effect preparations. It is used in medicine (increases levels of neurotransmitters including dopamine and norepinephrine) and sports dietary supplementation, in pre- and post-workout supplements, as well as fat burners, no-boosters and pre-workout creatine stacks and supplements and energizing beverages.
Dosage: In divided doses ranging from 100-300 mg per day.




Theacrine is a purine alkaloid which occurs naturally in the fruits of cupuaçu (Theobroma grandiflorum) and the leaves of Camellia assamica. It is structurally similar to caffeine but it has also additional ketone and methyl groups. It also energises, enhances focus and reduces drowsiness and fatigue. In contrary to caffeine, it has more lasting effects and rather does not affect blood pressure. Furthermore, it has been observed that the body develops tolerance to theacrine more slowly and that is why there is no need to increase its dosage to obtain the desired results. 

Like caffeine, theacrine can bind to adenosine receptors without activating them. Nonetheless, its effects depend on the dosage. Its high doses block adenosine receptors whereas low doses have the opposite effects – they boost adenosine levels in the hippocampus and that is probably why they may reduce negative effects of excessive caffeine intake. In addition, theacrine modulates dopamine receptors. Their activation leads to higher motivation and enhanced cognitive skills. It is also believed to have analgesic and antioxidant effects.

In supplementation, theacrine is treated as a stimulant. It is used to reduce drowsiness and fatigue and boost mental performance. It is often combined with caffeine to enhance and prolong its effects and prevent the harmful consequences of excess caffeine.

Theacrine is most frequently found in pre-workout supplements and fat burners based on stimulants. Single-ingredient preparations with pure theacrine are also available on the market.  

Dosage: No official guidelines.

The most common daily dosage is from 50 to 300 mg. Doses below 50 mg will have a relaxing effect and those around 300 mg a stimulating effect. 




Caffeine (1,3,7-trimethylxanthine, 1-methylotheobromine) is a purine alkaloid occurring in the natural state in plants (Coffea arabica, Camelia sinensis, Paulinia cupana, Ilex paraguariensis), which acts as a natural pesticide, acting toxic to insects. Peculiar smell and taste also deters herbivores. Caffeine in the body inhibits the adenosine receptors in the brain, fighting fatigue and allowing for action activation. It has a beneficial effect on the metabolism of oxygen, which increases the exercise capacity (strength and endurance) and rapid post-workout recovery. In the sports supplementation, caffeine is used as a stimulant nervous system. It has the thermogenic potential and in combination with other substances (e.g. Polyphenols, both occurring in coffee beans, such as cocoa beans, tea leaves and mate) can effectively participate in the reduction of body fat. It is included in many dietary stimulants (creatine stacks, no-boosters, beverages). It is a component of fat burners. It is also in the form of mono-preparation supplements.
Dosage: 100-600 mg per day. Due to the long release of activity should not be used in the evening, before


N-methyl tyramine


N-methyl tyramine, also known as 4-hydroxy-N-methylphenethylamine, is a derivative of the amino acid tyrosine, occurring naturally in animal and plant foods, e.g. cheese, fish and chocolate. It may be vital in the process of fat burning and energy production. Because of that, it should interest many individuals doing sport.

According to some sources, adding N-methyl tyramine to a diet may stimulate the breakdown of fat which is important in sports supplementation. It affects probably lipolysis, which is the process of fat breakdown.

Studies show that this compound may increase cardiac output and that is why it boosts the transport of oxygen and nutrients. By releasing renin from the kidneys, it may have an indirect impact on the regulation of blood pressure. It probably promotes anabolic processes in skeletal muscles and therefore contributes to an increase in muscle mass.

Cocoa bean


Cocoa seeds come from the cocoa fruit (Theobroma cacao). It is widely used in the food industry – primarily for the production of cocoa powder and cocoa butter, which is used to produce e.g., chocolate. Raw, untreated, cocoa beans are a treasury of valuable nutrients, which is why they were included in the group of the so-called superfoods.

About 50% of the dry mass of cocoa seeds are fats – mainly saturated fatty acids (stearic and palmitic) as well as oleic acid and other acids from the EUFAs. 31% is carbohydrates, with up to 15% being non-digestible fiber.

Cocoa seeds also contain minerals (magnesium, iron, phosphorus, potassium, copper), amino acids (arginine, glutamine, leucine) and two alkaloids (theobromine, caffeine), showing a stimulating effect. In addition, they are extremely rich in polyphenols (catechins, anthocyanins, procyanidins) that have a beneficial effect on the human body. They are credited for the ability to regulate blood pressure, lower cholesterol and stabilize blood sugar.

Cocoa seed extracts are a popular ingredient in health-promoting preparations. They are also commonly used in slimming supplements, sometimes they are also added to pre-workout formulas and mild stimulants.
