Beta-Lactoglobulin

The purest fraction of whey protein — with 50% more leucine than standard whey.

About

Beta-Lactoglobulin is the predominant protein fraction in bovine whey, accounting for 45–57% of all whey proteins. While standard whey protein is a blend of multiple fractions, TWOZERO® isolates BLG exclusively — bringing you whey protein in its purest and most effective form.

BLG's distinctive molecular structure enables rapid gastric transit and efficient intestinal absorption, ensuring your body receives amino acids quickly after training. Its exceptional leucine content — approximately 50% higher than standard whey protein isolate — makes it uniquely effective at activating muscle protein synthesis, the process your body uses to repair and rebuild muscle tissue after exercise.

Facts

1
BLG contains approximately 50% more leucine per gram than standard whey protein isolate.
2
A 2025 clinical study found that BLG offered a significant advantage over whey protein isolate in essential amino acid, BCAA, and leucine bioavailability.
3
Research found that BLG stimulates canonical muscle anabolic signalling pathways.
