Vitamin C

Information


Vitamin C (ascorbic acid) it is a vitamin soluble in body fluids, can be taken from foods (fruits and vegetables), or as drug derived synthetically. The largest of its resources can be found in broccoli, Brussels sprout, kale, black currant fruit and hawthorn, citrus fruits, tomatoes, Savoy cabbage, potatoes. In fact, intake of vitamin C of the food products does not limit the absorbed quantity. Vitamin C (ascorbic acid) is a potent antioxidant, it is an antitoxic, increasing the immune system due to the elimination of risk of bacterial contamination. Vitamin C prevents rupture of blood vessels, affects the blood cholesterol level. It substantially increases the absorption of iron. Inhibits the growth of cancer cells. Lowers stress levels.
Vitamin C deficiency causes abnormal development of connective tissue, cracking capillaries, abnormal calcification of bone tissue, impaired
absorption of iron, scorbutus. With the lack of vitamin C, all kinds of injuries do not heal up properly. Vitamin C deficiency can be caused by smoking; each cigarette is destroying up to 100 mg of vitamin C.
Dosage: The demand is 60-80 mg daily. It does not limit the ability to consume higher doses. Some side effects may occur only with longer
taking of synthetic vitamin C.

Ascorbic acid

Information

Ascorbic acid – vitamin C. Its biologically active form is the L-isomer, which negatively rotates the polarised light, so that it is a dextroisomer (laevorotatory vitamin C does not exist). It is a strong antioxidant; it reduces the amounts of free radicals, which reduces oxidative stress, a factor leading to cell apoptosis, which is why it is indicated to be a cause for premature ageing.

It supports the immune system functions and increases body system immunity. It is an essential element of the collagen synthesis path, which is why it positively affects the condition of connective tissue. Hence, it promotes also wound healing and increases the durability of capillary vessel. It is involved in transformations of tyrosine and carnitine as well as of some nutrients, so that it affects metabolism. It can also have an impact on the nervous system functions, as it reduces mental fatigue.

Higher supply of vitamin C is especially recommended in the periods of more intensive body system burden, after infections and in order to accelerate regeneration. The indications for increased supply of the vitamin are also hard physical work or intensive trainings.

L-Citrulline

Information

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 muscle-zone.pl

Dosage: In divided doses ranging from 100-300 mg per day.


 

Caffeine

Information

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
sleep.


 

Senegalia Berlandieri

Information

Senegalia Berlandieri is a source of numerous alkaloids, among which the most numerous are: N-methyl-N-phenylamine, tyramine and phenylethylamine. Similarly to Acacia Rigidula, Senegalia Berlandieri promotes the required growth of energy and mood improvement, which it owes to its influence on increasing the level of dopamine and adrenaline in the organism. Senegalia Berlandieri extract also intensifies lipolysis and stimulates metabolism.

Phenylethylamine derivatives (PEA) contained in the extract of this plant are responsible for the effect of good mood (they stimulate the secretion of serotonin and dopamine), cause positive attitude to life and increase the willingness to act.

Thanks to its properties stimulating the nervous system, optimizing well-being and intensifying lipolysis, the extract from Senegalia Berlandieri is the component of many extremely effective and strong pre-workout boosters, at the same time being an effective DMAA substitute.

L-DOPA

Information

L-DOPA - an amino acid, commonly called Levodopa, enantiomer of L-dihydroxyphenylalanine, belonging to the group of catecholamines. It is present in the human organism on the pathway of adrenaline biosynthesis. It is produced from tyrosine and is a precursor for subsequent reactions of compounds produced in this chain - dopamine, noradrenaline and adrenaline.

Thanks to the ability to cross blood-brain barrier, it is an incredibly effective supplement as for the promotion of cognitive functions and emotional states. It is conducive to the synthesis of dopamine and therefore it promotes its concentration and effectiveness in the organism. In this way, it positively influences the level of motivation and well-being. Due to the presence of dopamine in the extrapyramidal system, where it is responsible for neuromotor coordination, it is used in the therapy of Parkinson’s disease (the etiology of which consists in disturbing the synthesis of this neurotransmitter).

More globally, supplementation with levodopa may be conducive to the synthesis of subsequent catecholamines on the pathway of their biosynthesis, i.e. noradrenaline and final adrenaline. Therefore, it may demonstrate a stimulating effect.

Supplementation with L-DOPA also positively influences the secretion of testosterone and the human growth hormone. Due to its wide effectiveness in the organism, it may be also effectively used in order to promote sexual functions in men.

Theophylline

Information

Theophylline is a natural compound from the group of methylxanthines, which is currently obtained also in a synthetic way. In natural conditions, theophylline can be also found in i.a. tea leaves and cocoa beans.

It has anti-inflammatory and relaxing effect, therefore as a drug it finds application in the treatment of asthma. In case of theophylline - as an ingredient of dietary supplements - the mechanism based on inhibiting the activity of phosphodiesterase is the most important here - an enzyme responsible for cAMP breakdown. Theophylline, by being an inhibitor of this enzyme, contributes to the increase of intracellular concentration of cyclic AMP, at the same time increasing thermogenic and lipolytic processes and increasing the ability to concentrate as well as reducing the feeling of fatigue.

Therefore, theophylline demonstrates similar activity to caffeine, additionally positively influencing respiration and improving blood flow through kidneys. These properties makes theophylline a valuable ingredient of fat burners and pre-workout supplements.

Yohimbine

Information

Yohimbine is a natural component of the indole alkaloid yohimbine, ingredient of bark of yohimbe (Corynanthe yohimbe), a recognized aphrodisiac and increasing potency mean. It stimulates the nervous system by blocking the adrenergic receptors alpha-2. Tree bark of yohimbe is also a source of alkaloids (isoyohimbine, aloyohimbine), which can enhance its performance. With the right dosage, taken with caffeine on an empty stomach and a longer period before taking a meal, it enhances the process of lipolysis due to increased levels of norepinephrine in the body.
In the sports supplementation
it helps to reduce body fat (especially in programs of weight control and its composition), taken before physical activity. It comes in the form of mono-preparation supplements, extracts from yohimbe tree bark, synthetics and in supplements with thermogenic effect. Available for purchase at muscle-zone.pl
Dosage: No specific dosage standards. Some sources give optimal dose of 0.2 mg / kg
of body weight (usually used at 5-10 mg per day).


 

Huperzine A

Information

Huperzine A - an alkaloid of plant origin having the ability to penetrate the blood-brain barrier, it is a negative catalyst for the degradation of acetylcholine, that improves nerve conduction and having a significant impact on the concentration, cognition and memory. It helps mitigate the effects of oxidative stress, and prevents the depressions, has neuroprotective actions improving well-being. In the sports supplementation it is recommended at pre-workout, pre-effort and during workouts in order to improve concentration, as an component of advanced creatine stack, no-boosters as well as herbal remedies that improve mood.
