L-Aspartic Acid

Compare every L-Aspartic Acid product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.

Non-essential amino acid involved in energy production and neurotransmitter synthesis

We rank L-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.

What it is

L-Aspartic Acid is a non-essential amino acid. Amino acids are the building blocks that the body uses to make proteins, and "non-essential" means your body can produce enough of it on its own without needing to get it from food.

Why it's used

It is primarily used to support two main functions in the body:

How it's made

To create this supplement commercially, manufacturers typically use a process called fermentation. This involves using specific bacteria or microorganisms to break down a sugar source, which then produces the amino acid in large quantities. The resulting liquid is filtered and purified into a concentrated powder before being put into capsules or tablets.

What it typically costs

This ingredient is generally mid-range in price. This is because the fermentation process required for production is more involved than simple extraction, but the raw materials used are common and widely available.
