Taurine is an organic acid specifically a sulfonic acid. Taurine is sometimes considered an amino acid but it is not an amino acid in the usual biochemical meaning of the term.
“found that taurine increased cell proliferation in the dentate gyrus through the activation of quiescent stem cells, resulting in increased number of stem cells and intermediate neural progenitors. Taurine had a direct effect on stem/progenitor cells proliferation, as observed in vitro, and also reduced activated microglia. Furthermore, taurine increased the survival of newborn neurons, resulting in a net increase in adult neurogenesis.” 3
The May 2015 study concluded:
“Together, these results show that taurine increases several steps of adult neurogenesis and support a beneficial role of taurine on hippocampal neurogenesis in the context of brain aging.” 4
A study from February 2015 investigated whether antenatal taurine improved neuronal regeneration in fetal rats. The study concluded that taurine increased the survival of new neurons which increased adult brain cell creation. 5
Unfortunately, taurine levels decline with age which leaves the major organs of the body, especially the brain and heart, without this vital nutrient.
The diet can provide some amounts of taurine primarily from fish and meats. An omnivore diet is determined to contain around 58 mg (range from 9 to 372 mg). One study found that taurine intake was estimated to be generally less than 200 mg/day, even in individuals eating a high-meat diet. 6
Taurine from supplementation is a better alternative, especially for vegans and vegetarians, and is very inexpensive.
