Leucine There are three branch chain amino acids and with valine (one of these), leucine plays a significant role in energy production, muscle metabolism and stress management. Skeletal muscle uses these amino acids directly for production of energy and protein. When there is increased stress then these amino acids are used more than any other. Studies have shown that when there is starvation, physical trauma (such as surgery or injury) or infection then branch chain amino acids are required in higher amounts.

Leucine and Olivoponto Parkinson's Disease

In studies it was revealed that the 5% of Parkinson's patients who suffer from olivoponto cerebellar atrophy respond well to high doses of leucine, probably because that particular amino acid lowers the brain levels of dopamine.

For the 95% of Parkinson's patients who require an increase in dopamine levels, personal reports given by individuals taking Noni juice have demonstrated an improvement in ease of movement and speech as well as other symptoms of Parkinson's Disease.

This is an interesting example of where the adaptogenic properties of Noni juice is demonstrated.

Leucine is a component of elastin (a major component of connective tissue) and is a potent stimulator of growth hormone. This latter effect is particularly important for growing children and for wound healing.
