The Claim

Supplementation with glutamine, glutamate, and aspartate alters the serum amino acid profile in weaning piglets by increasing lysine, arginine, and threonine under low-energy conditions and aspartate under normal-energy conditions, indicating a diet-dependent shift in amino acid metabolism and utilization.

How it works
1 study reviewed
In plain English

In weaning piglets, adding glutamine, glutamate, and aspartate to the diet changes the levels of other amino acids in the blood, increasing lysine, arginine, and threonine when energy intake is low and increasing aspartate when energy intake is normal.

See the scientific wording

Glutamine, glutamate, and aspartate supplementation alters the serum amino acid profile in weaning piglets, increasing lysine, arginine, and threonine under low-energy conditions and aspartate under normal-energy conditions, indicating a diet-dependent shift in amino acid metabolism and utilization.

Why this might work

When piglets eat less energy, their guts use glutamine, glutamate, and aspartate to make energy and repair the intestinal lining. This repair process turns on more transporters that pull other amino acids like lysine, arginine, and threonine from the gut into the blood. When piglets eat enough energy, the same supplements boost aspartate directly because the gut doesn’t need to repair itself and just uses the extra aspartate. This changes the mix of amino acids in the blood depending on how much energy the piglet gets.

  1. Study: Effects of glutamine, glutamate, and aspartate on intestinal barrier integrity and amino acid pool of the small intestine in piglets with normal or low energy diet

    When young pigs eat less energy, adding glutamine, glutamate, and aspartate helps their guts heal and changes which other amino acids are available in their blood—raising lysine, arginine, and threonine. When they eat normally, it just raises aspartate. So their bodies use these amino acids differently depending on how much energy they have.
