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.
Alpha GPC (L-Alpha Glucerylphosphorylcholine, alphaglycerylphosphorylcholine) occurs naturally in the brain and milk. It is a chemical compound (a derivative of choline and its provider in the body) providing a precursor for the synthesis of acetylcholine, which is a neurotransmitter. Probably it has an impact on the secretion of the growth hormone that allows the intensification of tissue regeneration and it is improving the general condition and forming of proper body building.
The medicine uses it in the neurological treatments (stress, depression). In the sports supplementation is rarely used. It is a part of the supplements supporting a night renewal process.
Choline belongs to the soluble in liquids group of B vitamins. It is an organic nitrogen base containing lecithin, and acetylcholine. Together with inositol is involved in the metabolism of fats and cholesterol metabolism, preventing its accumulation on the walls of arteries and deposits in the gallbladder. With the penetration of the brain, contained lecithin improves its action and improves memory. Used in the treatment of age-related diseases (Alzheimer's). It occurs in plant foods: yeast, wheat germ, lecithin, green leafy vegetables and egg yolks.
Green tea extract is a concentrate that contains biologically active compounds: polyphenols (e.g. catechin, in the form of EGCG - epigallocatechin gallate), having antioxidant properties and a small thermogenic potential, modifies the action of testosterone metabolites, DTH. Green tea extract is an ingredient of many sports supplements containing fat burners, having pro-health and vitaminizing effect; also for those with low physical activity as an antioxidant and slimming supplement. Available either as mono-preparations, ready drinks, and above all as an extract.
Dosage: 200-500 mg per day (depending of the content of other active bio-components).
L-theanine is an amino acid, not building proteins, occurring naturally in the dried green tea leaves, absorbed from the gastrointestinal tract, overcomes easily blood-brain barrier, affecting the nervous system and the relation between neurotransmitters (e.g.dDopamine, serotonin, gamma-aminobutyric acid), with a relaxing effect and increases the psycho-physical capacity, (concentration, memory, alertness). Recommended for use for people burdened with considerable physical effort, athletes of sport disciplines that require concentration and memory, also for students in the period before exams. Available in the form of mono-preparations and multi-component relaxing and post-workout anti-stress supplements..
Dosage: customarily used in supplementation 50-200mg 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.
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.
