- Isoleucine – Involved in muscle metabolism and immune function
- Leucine – Supports muscle protein synthesis and energy production
- Lysine – Essential for calcium absorption and collagen formation
- Methionine – Plays a role in metabolism and detoxification
- Phenylalanine – Precursor for neurotransmitters such as dopamine and serotonin
- Threonine – Supports immune function and fat metabolism
- Tryptophan – Necessary for serotonin production and sleep regulation
- Valine – Helps with muscle growth and tissue repair
2. Non-Essential Amino Acids
Non-essential amino acids can be synthesized by the body and do not require direct dietary intake. Some of these include:
- Alanine – Helps with glucose metabolism and energy production
- Aspartic Acid – Aids in cellular energy production
- Asparagine – Supports nervous system function
- Glutamic Acid – Important for neurotransmitter activity
