Compare every L-Threonine product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.
Essential amino acid important for protein synthesis and gut lining integrity
We rank L-Threonine 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-Threonine is an essential amino acid, which is a building block for protein that the body cannot make on its own. Because it is essential, it must be obtained through the food we eat or via supplements.
Why it's used
It is primarily used to support the following:
Protein synthesis: The process the body uses to build and repair tissues.
Gut lining integrity: Helping to maintain the strong barrier in the digestive tract that prevents harmful substances from leaking into the bloodstream.
How it's made
To produce this supplement commercially, manufacturers typically use a fermentation process. This involves using specific bacteria that are fed a sugar source, which causes them to produce the amino acid as a byproduct. The resulting mixture is then filtered and purified into a concentrated powder.
What it typically costs
This ingredient is generally mid-range in price. This is because the fermentation process required to isolate the amino acid is more complex than simple extraction, but there is enough global production capacity to keep costs from becoming premium.
