L-Tryptophan is a precursor of several compounds. It is transformed in our body to serotonin and can from there be transformed in several steps to melatonin (a neuro-hormone). Tryptophan is also used by our body to make niacin (vitamin B3). Niacin is important for the health of our skin and digestive and nervous systems. It is also known to increase the “good-type” or HDL cholesterol.
We live in an “aging” world; with growing global life expectancies that result in the expectation that over 65’s will make up 17% of the world’s population in 2050 (U.S. Census Bureau, 2015). That does not necessarily mean we will all be aging healthily. Many people expect some physical problems when getting older but find the prospect of their brain aging the most daunting. So …. what can we do to keep our brains young?
