PepForm Tryptophan - for a deep, sound, restorative sleep

Tryptophan is an essential amino acid and needs to be obtained from the diet. In the body, Tryptophan has a number of specialised functions - for example it is a precursor of the neurotransmitter serotonin. Scientific evidence concludes that tryptophan in doses of 1 gram or more produce an increase in subjective sleepiness and a decrease in the time to sleep. 

A study carried out in 2008 in Stanford on the college's men and women's swimming teams showed athletes who obtained extra sleep sprinted faster, turned faster and had a greater amount of kick strokes. The efficient delivery of the Tryptophan amino acid can ensure better relaxation and rest for athletes. This often neglected area of performance is becoming more prevalent as sports people are looking to every area to gain competitive advantage.

Glanbia's PepForm Tryptophan Peptides are made by a proprietary process that binds free form L-Tryptophan to peptides isolated from fresh sweet whey using advanced fractionation and separation technologies. This unique technology results in 40% Tryptophan content.

Our PepForm Tryptophan is absorbed faster than free form tryptophan amino acids and also has greater solubility, meaning better delivery in a final product. This ingredient is the perfect platform on which to build a 'rest easy' product solution for those athletes that need them most.
