A randomized controlled trial involving 16 participants was conducted to study the effects of leucine-enriched amino acids and whey protein at rest and after resistance exercise in older women.

KEY FINDING:

• Helps to stimulate muscle protein anabolism.* 

Source: Intake of low-dose leucine-rich essential amino acids stimulates muscle anabolism equivalently to bolus whey protein in older women at rest and after exercise (link)

A randomized controlled trial involving 24 participants was conducted to evaluate the effects of leucine-enriched amino acids on muscle protein synthesis compared to a large bolus of whey protein in older women.

KEY FINDING:

• Supports muscle protein balance by increasing anabolism and limiting catabolism.*

A clinical trial involving 36 participants was conducted to evaluate the effects of enriching an essential amino acid (EAA) mixture with leucine on muscle protein metabolism in elderly and young individuals.

KEY FINDING:

• Supports stimulation of muscle protein synthesis.* 

Source: A high proportion of leucine is required for optimal stimulation of the rate of muscle protein synthesis by essential amino acids in the elderly (link)
