Clear- Citrulline: Citrulline is a final product produced by the metabolism of the amino acid glutamine. It has the ability to be converted into L-arginine by the body and helps with proper kidney function.
- Glutamine: It is a semi-essential amino acid that can be produced by the body and mainly contributes to strengthening the immune system, brain health, and digestive system.
- BCAAs (Branched Chain Amino Acids): Branched-chain amino acids are essential amino acids that cannot be produced by the body. They consist of leucine, isoleucine, and valine and are known for their role in muscle development, maintenance, and repair.
- NAC: It is a supplement with antioxidant action that supports the liver, the respiratory, and the immune system.
- Arginine: It is a semi-essential amino acid that can be produced by the body and participates in protein synthesis, while also playing an important role in kidney function.
- Theanine: An amino acid known for its ability to promote relaxation and concentration without causing drowsiness. Particularly useful for stress management and improving mental clarity, making it ideal for physical and mental well-being.
- 5 HTP: It is a chemical byproduct of the amino acid tryptophan, which acts in the brain and central nervous system by contributing to the increase of serotonin production in the body.
- EAAs (Essential Amino Acids): The set of essential amino acids that cannot be produced by the body and require their intake exclusively from protein-rich foods.
- Glutathione: It is a tripeptide that functions as one of the body's most powerful antioxidants. It helps protect cells from oxidation, aids in detoxification, and supports the immune system.
- Serotonin Boost: Serotonin is a neurotransmitter that affects mood, sleep, and overall well-being. Amino acids such as L-Tryptophan and 5-HTP support the natural production of serotonin, offering benefits for mood and quality sleep.
- Tryptophan: Essential amino acid that contributes to the synthesis of serotonin and melatonin. Supports calmness, sleep, and positive mood, while also helping to reduce tension and stress.
- Tyrosine: It is an amino acid that supports the synthesis of important neurotransmitters, such as dopamine and adrenaline. It enhances concentration, alertness, and performance under stressful conditions, especially for athletes and individuals with intense lifestyles.
- Leucine: Essential amino acid (one of the three BCAAs) that activates muscle protein synthesis and contributes to recovery.
- Muscle Growth: Amino acids (BCAAs & EAAs) that directly stimulate muscle protein synthesis, prevent catabolism, and accelerate muscle recovery after intense training.
- Vasodilation & Protein Synthesis: Ingredients that increase nitric oxide (NO) production for improved blood flow/pump, while also activating the mTOR pathway for maximum muscle growth.
- Endurance & Energy: Amino acids that delay muscle fatigue, regulate lactic acid, and enhance dopamine production for sustained energy and mental focus.
- Immune System Support: Strong amino acids that protect the gut, boost glutathione production (an antioxidant), and shield the body from exercise-induced stress.
- Relaxation & Sleep: Natural neurotransmitters and amino acids that reduce stress, regulate serotonin and melatonin, ensuring deep and restful sleep.
- Non-GMO: Supplements with this label do not contain ingredients produced from genetically modified organisms (GMOs). Ideal for those who prefer natural and minimally processed ingredient sources.
- Gluten free: Gluten-free supplements do not contain this protein component, which is found in wheat, barley, and rye. They are ideal for individuals with gluten intolerance, or those who prefer a gluten-free diet.
- Sugar Free: Supplements without added sugar are suitable for those following a low-sugar diet or diabetics. They offer a healthier alternative for maintaining blood sugar levels.
- Vegetarian: Supplements suitable for vegetarians do not contain meat, fish, or animal by-products from slaughter, but may include dairy, eggs, or honey. Ideal for those following a vegetarian diet.
- Vegan: Supplements that are suitable for vegans do not contain animal ingredients or derivatives, such as milk, eggs, or honey. They are designed to support a strictly plant-based lifestyle.
- Lactose Free: Τα συμπληρώματα χωρίς λακτόζη είναι ιδανικά για άτομα με δυσανεξία σε αυτή ή για όσους αποφεύγουν τα γαλακτοκομικά προϊόντα.
- Soy-Free: Supplements labeled this way do not contain soy or its derivatives and are suitable for people with soy allergy or sensitivity.
- The BCAA ratio (Leucine:Isoleucine:Valine) indicates the concentration of Leucine, the key amino acid for muscle protein synthesis. 2:1:1 is the natural ratio, while higher ratios (e.g., 4:1:1, 8:1:1) provide extra support.
