What is the Link between Amino Acids & Neurotransmitters? Well, Amino acids are the building blocks of protein. Protein consists of long chains of amino acids and there are 20 different types of amino acids. Neurotransmitters are chemical messengers within the body such as serotonin, GABA, dopamine, acetylcholine, endorphins and adrenaline. Their job is to transmit signals around the body via muscles, glands and nerves. They are part of the nervous system and play a crucial role in our development and many bodily functions. Reducing symptoms of ADHD Acetyl-L-carnitine: ALC is an amino acid derivative. One study reported that supplementation with ALC significantly reduced symptoms of ADHD, such as hyperactivity and social behaviour in atrial of 51 children aged 6–13). This may be due to ALC stimulating the release of dopamine in various brain regions, L-Theanine: L-Theanine is an amino acid found in both green and black teas and there is a component within it called n-ethyl glutamic acid that may have positive calming central nervous system effects. It has the ability to cross the blood-brain barrier, helping to regulate dopamine and serotonin to create a calming effect on the mind. GABA: GABA is a naturally occurring amino acid that acts as a neurotransmitter in your brain. GABA works by blocking certain brain signals and decreasing activity in your nervous system. 5-HTP and Serotonin: 5-HTP is a naturally occurring amino acid produced from the essential amino acid L-tryptophan, which also helps to make serotonin. 5-HTP is the precursor for some neurotransmitters which include serotonin and melatonin. So, L-tryptophan (which can be found naturally in foods) converts to 5-HTP which can then help to make serotonin and melatonin. Serotonin, which is also known as 5-HT, may improve mood and promote feelings of well-being. It may also impact appetite, sleep cycles and pain perception. Dopamine: Dopamine is known as the pleasure neurotransmitter because it is responsible for making us feelgood and it activates the reward system in our brains. It also helps us to focus and to learn new information. Contact Us We hope the information above proves useful and helps you to improve your general health and well-being.
