Amino acid that stimulates luteinising hormone and testosterone production
We rank D-Aspartic Acid by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
D-Aspartic Acid is a specific type of amino acid, which are the building blocks used by the body to create proteins. While most amino acids in the body are "L-form" (the standard shape), this version is the "D-form," meaning it has a mirrored molecular structure.
It is primarily used to help increase the production of testosterone, a key hormone for muscle and bone health. It achieves this by stimulating the release of luteinising hormone, which is a chemical messenger that tells the body to produce more testosterone.
Commercial manufacturers produce this supplement through a process of chemical synthesis. This involves combining specific raw chemical components in a controlled environment to build the amino acid molecule from scratch. Once the powder is created, it is typically put into capsules or blended into powders for sale.
This ingredient is generally mid-range in price. This is because the chemical synthesis required to create the mirrored D-form structure is more complex than producing standard amino acids, but there is enough industrial supply to keep it from being a luxury-priced item.
