Branched Chain Amino AcidsIsoleucine
Isoleucine is a branch-chain (BCAA) amino acid involved in the regulation of blood sugar levels, is necessary for muscle growth, and is needed to make hemoglobin, the oxygen-transporting molecule in red blood cells.
Branched Chain Amino AcidsLeucineLeucine is a branched-chain amino acid (BCAA), and it accounts for 35% of the total amino acid content in muscle. It is vitally important for protein synthesis and has been proposed as an anti-catabolic agent that could stimulate skeletal muscle growth.
Branched Chain Amino AcidsValineValine assists in metabolism regulation, muscle control, and maintaining nitrogen balance in blood, tissues, and muscles. This amino acid also helps with the formation and maintenance of red blood cells and muscle tissue, and it contributes to healthy brain function.
Branched Chain Amino AcidsLeucine, Isoleucine, and Valine.A branched-chain essential amino acid (BCAA) is any one of the three essential amino acids that have a branched side chain. The three BCAAs are leucine, isoleucine, and valine. These amino acids have similar structures, but their side chains vary so they will have distinct functions within the body.
Essential Amino AcidsEssential Amino Acids cannot be made by the body and therefore must be provided in the form of essential amino acid supplements and foods. Amino acids are essential to provide protein for muscle growth and repair; essential amino acids also help promote better function of all parts of the body and mind as well as supporting good health and general well-being.
Essential Amino Acids
HistidineHistidine is an essential component of hemoglobin and neurotransmitters in the brain. Histidine helps transport carbon dioxide from tissues to the lungs. Histidine also increases the concentration of glucose in muscle tissue before exercise.
Essential Amino AcidsLysineLysine is one of the essential amino acids that humans require in their diet. It helps in the growth and repair of tissues, production of antibodies against infections, muscle recovery after exercise, absorption/utilization of calcium, blood clotting, production of lactic acid & carnitine which are important energy-producing nutrients.
Essential Amino AcidsMethionineMethionine sulfur compound is a precursor to cysteine and l-glutathione. In the body, it acts as an antioxidant agent, helps the liver function properly, assists in synthesizing fatty acids. Methionine builds muscle proteins that help fight infections and maintain a healthy intestinal system. It is also important in the production of antibodies, hormones, and enzymes that are used to prevent damage from free radicals. It is essential for growth and tissue repair.
Essential Amino AcidsPhenylalaninePhenylalanine helps to produce dopamine and norepinephrine. It has has been shown to elevate mood by increasing levels of dopamine which affects attention, memory, pleasure-seeking behavior, and energy levels. Phenylalanine can be beneficial for people who suffer from depression, stress, and physical fatigue. It also plays a role in the production of serotonin by converting it into tyrosine which is responsible for mood balance and cognitive function. The brain uses serotonin to regulate appetite, sleep patterns, memory, learning, and mood.
Essential Amino AcidsThreonineThe primary purpose of threonine is to help build collagen. Collagen is a protein found in cartilage, connective tissue, bone, ligaments. When developing collagen, the body will often use threonine to make serine and glycine, which are used in the synthesis of collagen. Threonine also helps to regulate fat deposits by helping break down body fat and allowing it to be removed from the body.
Essential Amino AcidsTryptophanTryptophan is used to make many different molecules in the human body including serotonin, melatonin, and niacin. Serotonin is a neurotransmitter, which helps to regulate mood and sleep. Niacin is an important molecule that the body needs for metabolism.
Non-Essential Amino Acids
Acetyl-L-carnitineAcetyl-L-Carnitine is a derivative of the amino acid L-carnitine and is used in the body to produce energy.
Non-Essential Amino Acids AlanineAlanine is an amino acid that is used to make proteins. It helps break down tryptophan and vitamin B-6, fuels muscle energy, strengthens our immune system, and helps our body process sugars. Used as the building blocks for methionine and cysteine.
Non-Essential Amino AcidsAsparagineThe role of Asparagine in the human body is to produce proteins but also to break down toxic ammonia, play a role in protein modification and make neurotransmitters. Its role is important for many different parts of the cells and processes within them.
Non-Essential Amino AcidsAspartic AcidAspartic Acid's role in the human body is to be part of many proteins and enzymes. One role that Aspartic Acid plays is within the Krebs Cycle. The Krebs Cycle is a series of chemical reactions that break down Acetyl CoA. Within the Krebs Cycle, Aspartic Acid plays a role in transforming Acetyl CoA into Citric Acid, which is used by the body as an energy source.
Non-Essential Amino AcidsGlutamic AcidGlutamic acid is an amino acid that the body uses to form proteins and maintain protein balance in the body. Glutamic acid is converted, once in the body to Glutamate. Glutamate is the primary excitatory neurotransmitter in the Glutamate receptors are found throughout the whole brain where brain cells are stimulated, helping with memory and learning, and controlling voluntary muscle movement like walking and talking.
Non-Essential Amino AcidsNon-essential amino acids can be synthesized in the body from other compounds. They are produced by the body itself. Non-essential amino acids perform a number of different functions within the body. They provide energy when there isn't enough glucose to meet energy demands, provide the building blocks for proteins, and change into compounds that affect neurotransmitters.
Semi Essential Amino AcidsArginineArginine is a non-essential amino acid that becomes essential in certain conditions, such as certain disorders or after surgery. Semi-essential indicates that the amino acid can be synthesized in our body, but when synthesis is inadequate or cannot meet demand, then it will become essential.
Semi Essential Amino AcidsArginineArginine plays many roles in the human body including wound healing, immune system function, and hormone secretion. Arginine is important for kidney function since it helps to produce creatinine. It also stimulates the vagus nerve, which improves heart rate variability and may reduce blood pressure.
Semi Essential Amino AcidsCysteineCysteine, a sulfur-containing amino acid, helps to detoxify the body from many different harmful substances. In addition, it also helps maintain healthy hair and nails as well as aids in the production of collagen which is an important structural protein found in connective tissue.
Semi Essential Amino AcidsGlutamineGlutamine is an important source of energy for cells throughout the body during periods of metabolic stress, has a role in cellular protection and repair, and plays a significant role in the human immune system. A number of different organs and systems can utilize Glutamine, including liver cells, muscle cells, and neurons within the central nervous system.
Semi Essential Amino AcidsGlycineGlycine along with glutamic acid and proline are the main components of collagen. It serves as a neurotransmitter and regulates pain-sensing nerves in the spinal cord. It has been known to improve sleep and reduce stress and anxiety when taken in supplement form.
Semi Essential Amino AcidsProlineProline is required to make the collagen needed for the body. Proline aids in the production of hemoglobin. Proline is needed for proper liver health and to lower blood pressure. The human body cannot make proline. It must be obtained through food or supplements.
Semi Essential Amino AcidsSerineIt has been shown to play an important role in the metabolism of cell membranes and nucleic acids. It is seen to play a particularly important role in blood clotting. Serine can be synthesized in the body by other amino acids or formed into proteins, which are used for the growth and repair of tissues.
Semi Essential Amino AcidsTyrosineIts function in the human body is to act as a precursor for DNA and RNA, melanin (pigment), thyroid hormones, adrenaline, and dopamine. It is also important for proper immune system function. Tyrosine also acts as an antioxidant.
Semi Essential Amino AcidsOrnithineOrnithine is an Amino Acid that functions as a precursor for the urea (waste) cycle and helps to promote muscle protein synthesis. It also supports immune function, energy production, and lipid metabolism.
