L-Theanine - Feed Ingredient
L-Theanine is a non-proteinogenic amino acid naturally found in the leaves of Camellia sinensis (green tea). It is known for its calming and neuroactive properties in humans and animals, and it is used in equine supplements primarily as a functional or behavioral support ingredient rather than for its nutritional value.
In equine formulations, L-theanine is included to help promote a calm demeanor without causing sedation. It is typically added in purified, synthetic form, as green tea extracts are not commonly used directly in horse feeds due to variability and potential caffeine content. L-theanine’s mechanism of action involves modulation of neurotransmitters, although equine-specific studies are limited.
The following equine feeds, supplements and products contain L-Theanine as an ingredient.
