Type: Amino Acids
Building blocks of proteins. Essential amino acids must be obtained from diet, while non-essential can be synthesized by the body.
Absorption: Amino acids are generally well-absorbed. Some forms (like citrulline) are more effective than others (like arginine).
Interactions: Generally safe but high doses can cause digestive issues. Some amino acids can affect neurotransmitter levels.
