β-alanine supplementation induces taurine depletion and RGC death. • The loss of traced-RGCs is higher than of Brn3a + RGCs, suggesting an axonal transport impairment. • OCT analysis revealed a reduction of the RNFL thickness induced by taurine depletion. • β-alanine supplementation should be used with care.

Abstract. Taurine is an abundant, β-amino acid with diverse cytoprotective activity. In some species, taurine is an essential nutrient but in man it is considered a semi-essential nutrient, although cells lacking taurine show major pathology. These findings have spurred interest in the potential use of taurine as a therapeutic agent.
Taurine and beta-alanine are amino acids found in the human body. Both are considered to be non-essential amino acids. This means that the body is able to synthesize both of them naturally. This being said, many people choose to also supplement with them for different reasons.
Taurine, a substrate of taurine transporter, has functions as a neuromodulator and antioxidant and beta-alanine, a taurine transporter inhibitor, has a role as a neurotransmitter in the brain, and they were expected to be involved in depression-like behavior and antidepressant treatment.
When consumed as a dietary supplement, beta-alanine passes from the bloodstream into skeletal muscle via a beta-alanine and taurine transporter that's dependent upon both sodium and chloride availability. Once it enters a skeletal muscle cell, it binds with the essential amino acid L-histidine to form the dipeptide carnosine.
Purpose To investigate the effects of chronic beta-alanine (BA) supplementation on muscle taurine content, blood clinical markers and sensory side-effects. Methods Twenty-five healthy male participants (age 27 ± 4 years, height 1. 75 ± 0. 09 m, body mass 78. 9 ± 11. 7 kg) were supplemented with 6. 4 g day−1 of sustained-release BA (N = 16; CarnoSyn(tm), NAI, USA) or placebo (PL; N = 9 .
Based on the current available literature, the conclusions of the ISSN are as follows: 1) Four weeks of beta-alanine supplementation (4-6 g daily) significantly augments muscle carnosine concentrations, thereby acting as an intracellular pH buffer; 2) Beta-alanine supplementation currently appears to be safe in healthy populations at recommended.
What is beta-alanine, and what does it do? Beta-alanine is a natural occurring amino acid that works to improve intramuscular carnosine concentrations. Higher intramuscular carnosine concentrations help to provide you with higher energy levels, and better endurance and athletic performance.
Nausea; Diarrhea; Taurine deficiency - Taurine and beta-alanine share the same transporter and should be kept in balance as too much of one can cause a deficiency in the other. ; Paresthesia - This is a relatively harmless tingling feeling caused by high doses of beta-alanine. You can prevent this side effect by lowering the dose or spreading it evenly throughout the day.
Conclusions: The current study showed that 24 weeks of BA supplementation at 6. 4 g day -1 did not significantly affect muscle taurine content, clinical markers of renal, hepatic and muscle function, nor did it result in chronic sensory side-effects, in healthy individuals.
Since there is a group of studies that used either beta-alanine by itself or beta-alanine with taurine, we examined them to determine if there were any differences in the resulting carnosine concentrations. While more research is always needed, there are quite a few beta-alanine vs. beta-alanine plus taurine studies, and their outcomes are all .

The beta-alanine-mediated reduction in taurine levels is too small to affect taurinomethyluridine levels. Nonetheless, it interferes with mitochondrial protein synthesis, as exemplified by a decrease in ND6 protein content. Thus, beta-alanine does not cause alterations in mitochondrial protein synthesis through the lowering of taurine levels.
This study investigated the effect of taurine and β-alanine supplementation on muscle function and muscle taurine transporter (TauT) protein expression in mdx mice. Wild-type (WT) and mdx mice (5 months) were supplemented with taurine or β-alanine for 4 weeks, after which in vitro contractile properties, fatigue resistance and force recovery, and the expression of the TauT protein and .

In animals, this 3% intake of beta-alanine in water may reduce circulating taurine levels by 50% to 77% and may reduce cardiac levels of taurine by 16. 6-22. 7%. In animal studies, cellular taurine can be reduced up to 50% with continual administration of beta-alanine via the drinking water
What are Taurine and Beta-Alanine? Taurine is a conditionally essential beta amino acid because it can be synthesized in the body by the amino acids methionine and cysteine with the cofactor vitamin B-6. Taurine contains sulfur and is the main building block of bile salts.
Results β-alanine caused a time-dependent decrease in cellular taurine content, which were reduced in half after 48 hrs of incubation. The amount of taurine in the mitochondria was considerably less than that in the cytosol and was unaffected by β-alanine treatment.

β-Alanine is a rate-limiting precursor for synthesis of the dipeptide carnosine (β-alanyl- l -histidine), which is produced within and stored in high concentrations in skeletal muscle, heart and olfactory receptor neurons. 1 2 β-Alanine supplementation has been shown to boost the carnosine content of skeletal muscle. 3 This reflects the fact tha.
Bottom Line Athletes and those who are active may take beta-alanine supplements to boost performance and strength. Here's what beta-alanine can do for you and your health. Beta-alanine is a.
