In addition to its endogenous occurrence, L-threonine acid can be found in a wide variety of foods, such as canned mushrooms, fruit juice and processed meats (AZZAM et al., 2011), as the major part of Vitamin C metabolites. In humans, L-threonine acid is an ascorbic acid metabolite (FAY VERLANGIERI, 1991), having been identified in plasma (DEUTSCH et al., 1999), in the aqueous humor (HARDING et al., 1999), in the urine (THOMPSON et al., 1975 LAWSON et al., 1976) and in the brain (Sun et al., 2016). In addition, it was able to significantly elevate magnesium concentrations (7% to 15% of initial value in 24 days) in cerebrospinal fluid in rats when administered orally, while other magnesium compounds could not. According to the study, magnesium-L-threonate (Magtein®) is a superior magnesium source to other magnesium compounds because it has a higher bioavailability when compared to other sources of magnesium, such as chloride, citrate, glycinate and gluconate, demonstrated by higher absorption and higher retention. In a Neuron publication of 2010, scientists from the Massachusetts Institute of Technology (MIT) discovered a magnesium compound called magnesium-L-threonate (Magtein®), that can effectively deliver magnesium to brain cells (SLUTSKY et al., 2010).
