Beta Alanine reviews are almost always positive ever since it was introduced to the supplement market place about 4 years ago. There was a ∼2-fold greater increase in muscle carnosine content in both muscle groups measured for the high dosing group (tibialis anterior: 2.04 mmol.kg−1 wet weight and gastrocnemius: 1.75 mmol.kg−1 wet weight increase) compared with the low dosing group (tibialis anterior 1.12 mmol.kg−1 wet weight and gastrocnemius 0.80 mmol.kg−1 wet weight increase).
The body of scientific data available concerning highly trained athletes performing single competition-like exercise tasks indicates that this type of population receives modest but potentially worthwhile performance benefits from β-alanine supplementation.
For example, in one of the first published studies on beta-alanine and human athletic performance, subjects received either a placebo, 20 g per day of creatine monohydrate , 800 mg of beta-alanine four times per day, or the same dose of beta-alanine plus 20 g of creatine monohydrate.
However, high levels of β-alanine were detected and quantifies in the 24-h post-infusion urine sample (3.7g, or 34% of the total infused) ( Fig 3A ). Intravenous beta alanine benefits infusion of irradiated β-alanine in one participant elicited symptoms of paraesthesia at different time points throughout the infusion period ( Fig 3B ).
An inherent problem of time trial tests in well trained participants who are familiar with the exercise protocol is that they are influenced by pacing strategies 27 and sometimes these pacing strategies do not produce optimal performance 28 There is also a variety, possibly an infinite number, of pacing strategies available to an individual 29 However, if pacing strategies were employed by the athletes in the present study variables such as heart rate, blood lactate and particularly the RPE responses to exercise would have been lower in the group supplemented with β-alanine.
Thus, these findings suggest that despite the beneficial effects of β-alanine supplementation on high intensity exercise capacity 9 - 10 , β-alanine supplementation does not influence longer duration (30 min - 1 hr), lower intensity, cycling performance.

Strong stimulants, enough to get you going at 5 am and ready to crush it. Moderate performance enhancing products - enough citrulline and beta alanine to provide a functional dose and increase performance significantly (as opposed to mega dosing it).
In contrast to L-alanine, which is a proteinogenic amino acid, β-alanine has no stereo center ( Figure 1 ). β-Alanine is incorporated into pantothenate (Vitamin B5), and therefore, is a precursor of Coenzyme A (CoA) and acyl-carrier protein, which shuttle carbon within the cell ( Voet et al., 2006 ). β-Alanine is a component of carnosine, a dipeptide concentrated in muscle and brain tissue, which underlies the wide use of β-alanine in humans as a strength enhancing supplement.
The effects of BA supplementation on the power output, kilograms lifted and movement velocity in response to the 5 weeks of training were assessed through a general linear model with repeated measures two-way analysis of variance as the Levene's test revealed the homogeneity of variances of the initial variables and the Shapiro Wilk's test confirmed their normal distribution.
Hence, jump height and average power values recorded in the CMJ test were similar in both groups despite more kilograms lifted (24 kg VS. 16 kg) and more sets accomplished (2.79 sets VS. 1.58 sets) in the BA supplementation group after 5 weeks of training.
The polyamines spermine and spermidine are converted via 1,3-diaminopropane to β-alanine ( Figure 2 ) in many plants and demonstrated in maize shoots ( Terano and Suzuki, 1978 ; Galston and Sawhney, 1990 ). Pericarp discs of tomato fruits were also shown to degrade spermidine to putrescine and β-alanine ( Rastogi and Davies, 1989 ). Spermidine is cleaved by the FAD- and heme-containing enzyme spermidine dehydrogenase EC 18.104.22.168 into 1,3-diaminopropane and 4-aminobutyraldehyde.
