Haya Labs L-tryptophan is a high-class food supplement which contains the essential amino acid tryptophan that plays an important role in the secretion of hormones, necessary for quick falling asleep, restful sleep and a lifted mood.

OstroVit D.A.A is a high-quality, state-of-the-art preparation consisting exclusively of a single substance, D-aspartic acid, this time in a raspberry-flavoured version. The product has been fragmented by undergoing a micronisation process, which allows for even better bioavailability.

Glutamine is the most abundant amino acid (the building block of protein) in the body. The body can make enough glutamine for its regular needs, but in cases of extreme stress ( very heavy exercise or an injury), the body may need more glutamine than it can make. Most glutamine is stored in muscles followed by the lungs, where much of the glutamine is made.

OstroVit EAA 1150 mg is a complex of exogenous and endogenous amino acids. The main task of the amino acids EAA is to protect muscles against catabolism and improve their regeneration after training. Our product contains amino acids: BCAA (L-leucine, L-valine, L-isoleucine), L-lysine, L-threonine, L-phenylalanine, L-methionine, L-arginine, L-histidine, L-tryptophan.

OstroVit Citrulline is a premium dietary supplement in capsules, containing citrulline malate in a 2:1 ratio, which helps, among other things, to protect muscles from fatigue and to regain full strength after hard, intensive training. By increasing nitric oxide synthesis, it also allows for better blood flow and significantly improved transport of oxygen and nutrients to cells.

OstroVit BCAA is a dietary supplement containing the highest-quality branched chain amino acids BCAA, in the best ratio of 2: 1: 1. These amino acids include: leucine, isoleucine, valine. They should be delivered to the body because they belong to the so-called exogenous amino acids - amino acids that the human body cannot produce by itself.

OstroVit Tryptophan is a supplement based on only one substance, which is L-tryptophan. High bioavailability and a high level of pharmaceutical micronization make Supreme Pure supplements of the highest quality. The product was created with the most demanding consumers in mind.

Arginine, Ornithine, Lysine.

Taurine Neurotransmitter is a free-form amino acid that participates in a variety of metabolic processes.

L-Glutamine is the most abundant amino acid in the body. Makes up more than 60% of the muscular amino acid pool.

HAYA LABS L-Tyrosine is an important element in the production of norepinephrine, a neurotransmitter that helps maintain a healthy appetite, pituitary and thyroid glands.

Haya Labs L-Arginine is a high-quality amino acid formula with arginine – amino acid, which promotes the growth of lean muscle mass, stimulates the immune system and blocks the harmful effect of free radicals.

OstroVit AOL is a dietary supplement in capsules supplementing the diet with three synergistically acting amino acids: L-arginine alpha-ketoglutarate (AAKG), L-ornithine and L-lysine.

OstroVit Glutamine is a top-class, advanced preparation that contains only one ingredient, which is L-glutamine. The supplement has been designed in such a way as to meet the expectations of the most demanding consumers.

OstroVit AOL is a powder dietary supplement that supplements the diet with three synergistically acting amino acids: L-arginine alpha-ketoglutarate (AAKG), L-ornithine and L-lysine. The product is based only on active substances, without the unnecessary addition of flavours, sweeteners, anti-caking or preserving agents. The mixture of three amino acids will help you increase muscle anabolism, naturally increase the synthesis of growth hormone (GH), which will improve endurance and strength in hard training.

CarnoSyn is the proprietary, patented form of Beta-Alanine. Beta-Alanine is a naturally occurring beta amino acid produced in muscle tissue as a component of carnosine.

Sugar-free, flavoured drink powder with sweeteners and vitamin b6, containing 6000 mg of bcaa per serving.

HAYA LABS L-Proline is an amino acid supplement, which supports the build-up of healthy tissues, increases the health of connective tissue and bones and supports the cardiovascular system.

OstroVit Tyrosine is a top-class, advanced preparation that contains L-tyrosine. The supplement has been designed in such a way as to meet the expectations of the most demanding consumers. Thanks to the developed micronization technology, the substance has been perfectly fragmented.

OstroVit Citrulline is a top class perfectly fragmented citrulline malate. It protects muscles against fatigue and helps in regaining full strength after hard and intense workouts. The increased synthesis of nitric oxide provides to better blood flow and significantly better transport of oxygen and nutrients to the cells.

OstroVit BCAA + Glutamine 1100 mg is a top-class supplement in capsules dedicated to physically active people, consisting of three branched amino acids, which are: leucine, valine, isoleucine and extremely important glutamine. The supplement does not contain unnecessary clumpers, fillers and other additives, and its micronization is at the highest level. The ideal bioavailability and excellent solubility of the product were dictated by the high demands of consumers.

Essential Amino Acid.

Everbuild Glutamine 5000 contains 100% pure L-glutamine of pharmaceutical quality. The L-glutamine itself is the most commonly met amino acid in the human body. Up to 60% of the amino acids in their pure form are made up of glutamine. Around 20% of the amino acids in the blood, meanwhile, are also made up of glutamine.

Arginine is one of the most important amino acids for bodybuilders and athletes as it stimulates the development of lean muscle mass and its components are intermediates in the metabolism of nitric oxides.

Tyrosine is not an essential amino acid, so our body is capable of producing it – even though in very small quantities – from phenylalanine essential amino acid. It can also be found in its natural form in banana, avocado and in most high-protein foods such as meat, dairy products and eggs.
