Beta-alanine and high-intensity training -
So, beta-alanine helps reduce fatigue and lactic buildup, which in turn helps you increase your exercise capacity and power output. And it can even help improve body composition The Journal of the International Society of Sports Nutrition published a study that showed subjects who took beta-alanine got better results from HIIT high-intensity interval training which resulted in gaining more lean body mass and endurance compared to a placebo group.
This is all important for physical health, but we did mention it goes beyond that. Beta-alanine supplementation can also help those that are aged 50 and above.
With aging, there is a natural loss of skeletal muscle mass, but what most don't know is that it leads to a decline in carnosine levels. Supplementing with beta-alanine can slow down that process, by boosting your carnosine levels. But you shouldn't wait until you're 50 to do so!
As you can see a lot, if not all, of the benefits, come from carnosine and not directly from beta-alanine. The reason you can't just supplement with carnosine instead of beta-alanine is that our bodies don't absorb it that well if it's supplemented by itself. In fact, when it's ingested your body breaks it down into beta-alanine and histidine.
Thus producing carnosine and increasing its levels, which is what you want, but you'd essentially be supplementing with carnosine in order to get beta-alanine.
All amino acids are present in natural foods, especially in meats. Although meat is rich in certain amino acids like carnosine, you still need a significant intake of beta-alanine to reap the performance benefits. But as always, follow a natural protein-rich diet, and use supplements for what they are - something extra that helps enhance your training, not something you rely on.
With that being said, the beta-alanine dosage can be anywhere from 3. Over consuming it, meaning above mg per day, can lead to one common unpleasant side effect - a tingling sensation. You've probably heard about this tingly sensation from other athletes or even felt it yourself, well, that feeling is thanks to beta-alanine.
The effects are similar to the pins-and-needles feeling you get when your foot falls asleep. This feeling is temporary, and according to the International Society of Sports Nutrition, harmless.
So, when exactly should you take it? It doesn't have to be taken at any specific time, you can divide it and take it in multiple doses throughout the day, but most prefer to take it before their workouts.
This is why it's a common ingredient in pre-workouts, including ours! Plus, it's free of yucky ingredients like artificial dyes and sweeteners, and unnecessary fillers! All to provide you clean, sustainable energy that will enhance your exercise performance.
A fitness journey requires commitment and hard work so you can be the best version of yourself, and Lab was created to help you get there. These products are not intended to diagnose, treat, cure or prevent any disease.

Based trainijg 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 doses; 3 The only reported side effect is paraesthesia tinglingbut studies indicate this can be attenuated by using divided lower doses 1. Beta-alanine is a non-proteogenic amino acid that is produced endogenously in the liver.There have higg-intensity several Hydration and sports for older adults qualitative review articles published on the topic, and amd we present a preliminary quantitative review of the literature through a meta-analysis.

This meta-analysis did not attempt to conduct a traditional qualitative review concurrently with the quantitative data traijing here, and therefore readers trzining directed to the traditional review articles referenced above for details of the studies included in this fraining.

Several other desirable high-inensity of studies were also discussed, Beta-alanone as the homogeneity of the participant population and the availability of information on the reliability of tgaining exercise annd and measures employed, however, trainign inclusion criteria remained as they were.
This analysis was limited to trainint using Beta-wlanine participants in placebo controlled, double high-intensoty trials, published in English language peer reviewed journals, and which had a trainin only supplementation group BA and a placebo group Pla.
Summary details of the studies included in traininh meta-analysis are listed in Table 1. Due to these inclusion criteria, several studies were excluded high-intwnsity the analysis, for trraining multitude of reasons.
These Beta-wlanine those with no β-alanine only znd group Hoffman trainong al. Pre- hugh-intensity post-supplementation mean and standard deviations SD were obtained from the original data included teaining the published papers.
Where this information was not available Sale et al. Unfortunately, further Low sodium meal planning was not received from Derave and his co-workers in relation to their data on Beta-alanine and high-intensity training peak high-intensuty production ttaining, as such, Bta-alanine data is not included in the meta-analysis.
High-intenwity effectiveness of the supplementation for BA and Pla groups was Beta-alanone by Beta-aanine the effect High-intwnsity, which is the difference between the pre- and post-supplementation measures, divided by the pooled SD of the two occasions. Therefore, effect size represents a common measure of treatment effectiveness, which allows amd findings of individual studies to be analysed together.
Where a smaller number represents a better result such as running performancethe subtraction is reversed and thus a positive effect size still represents a positive treatment effect.
Each effect size was then corrected to adjust for any positive bias due to small sample size Thomas and French The studies of Hill et al. Exercise measures were analysed as one complete group for the overall effect of β-alanine supplementation compared to a placebo.
Due to the mechanisms by which β-alanine is ans to have an ergogenic effect on exercise, the data were then sub-divided.
Where possible, data were separated traininf those generated by exercise capacity high-inteneity exercise performance tests.
Although exercise performance tests are deemed to have a greater level of ecological validity, they rely upon intrinsic pacing strategies which may not elicit optimal performance Hinckson and Hopkins If there is no fixed Beta-wlanine strategy, as may be the case in sub-elite athletes, then the effects of an intervention might be masked by large variance; if there is a fixed pacing strategy, as may be the case in elite or experienced athletes, it may not allow the effects of an intervention to be shown.
Therefore, exercise capacity and exercise performance data were analysed separately. Measures were also sub-divided by exercise duration, given that β-alanine supplementation increases carnosine concentrations in skeletal muscle and acts indirectly to increase muscle buffering capacity.
Finally, the dose of β-alanine administered above or below the average daily and total dose, as determined by mean and median was also investigated to determine if there was a xnd link between the dose and the effect of β-alanine.
Information regarding which tests were included trainimg each grouping is available in Table 2. With the data divided as BA and Pla groups, and the number of effect sizes in each group dictated by the variable being investigated, the data were analysed for skewness, kurtosis and normality of distribution.
Fifteen published investigations met the inclusion criteria see Table 1 for study details. Several studies employed multiple exercise tests and anv measures within those tests, therefore 57 effect sizes were calculated for inclusion in the analysis. A total of participants were included, subdividing into participants in the BA group and yigh-intensity in the Pla group; the average group size was 12 participants, with a range of 7—20 participants.
Of the participants, Of the 15 studies included in Beta-alaninne meta-analysis, 8 acknowledge the donation of the supplement used from a commercial company and 3 state the brand of supplement used, but 4 studies make no reference as to the source of the β-alanine administered Stout Beta-alabine al.
Furthermore, five manuscripts acknowledge an element of financial support for their study from a commercial company Hill et al. The effect size of the Pla group was 0. Further data analysis indicates that supplementation with a total of g of β-alanine the median dose across all studies would result in a median improvement of 2.
Twelve exercise performance measures were employed in six studies see Table 2 for details. When combined, tests such as rowing performance Baguet et al. The effect size of Pla and Beta-alaanine groups when subdivided by type of exercise test or measure.
Light grey represents Pla groups and dark grey represents BA groups. Thirteen of the fifteen studies included in this meta-analysis employed a total of 27 exercise capacity measures to investigate the effects of β-alanine supplementation.
BA groups had an tgaining size of 0. For the 9 measures lasting 60— s Beta-aanine was a significant difference between the effect size of the BA and Pla groups [0. However, once exercise duration increased over s the beneficial effects of β-alanine supplementation from the 34 measures become less pronounced, although still significant [BA 0.
Figure 2 demonstrates this pattern. The effect size of Pla and BA groups when subdivided by exercise duration. A large variety of supplementation protocols were employed, meaning that the total amount of β-alanine ingested by each participant varied from The difference in the median effect size between the BA and Pla groups for each study is plotted in relation to the total dose of β-alanine supplemented in Fig.
Through regression analysis, the data of Stout et al. The difference in the median effect size of the BA and Pla groups of each Befa-alanine in relation to the total dose of β-alanine supplemented.
To our knowledge, this is the first meta-analysis to be published on this topic and it shows that there is a significant effect of β-alanine supplementation on all exercise measures when taken as a single group.
Hihg-intensity indicates that supplementation with a total of g of β-alanine the median dose across all studies would result in a median improvement of 2. Assuming a linear relationship between running speed and percentage effect, if taining improvement was extrapolated and applied to a sporting event lasting around 4 min, such as a 1, m run, performance time would be improved by ~6 s.
It should be noted that this calculation is based upon the median effect across several studies, and the vast majority of participants in the studies of this meta-analysis are recreationally active individuals rather than elite athletes. Of these, only one yard shuttle run; Kern and Robinson falls within the time frame in which β-alanine supplementation is most efficacious 60— s.
These studies anx shown that, with Therefore, given the potential demonstrated for significant improvements in exercise lasting 60— s, this meta-analysis highlights the need for more studies investigating the effects of β-alanine supplementation on exercise performance of this duration.
However, to date, the available data suggests that β-alanine supplementation has no benefit on measures of exercise performance rather than exercise capacity. This result is perhaps unsurprising as only 2 of the 12 performance measures included in the trainong have shown a significant difference between the BA and Pla groups mean power output and peak power output in a 30 s cycle sprint, after min of previous cycling; Trainihg Thienen et al.
Adn, this is unlikely to be the true explanation for the results seen here as 3 high-intenaity the 6 studies conducted full familiarisation trials with the participants prior to testing Kendrick et al.
Although it can be argued that performance tests are more ecologically valid Coyle et higy-intensity.
Exercise capacity tests do not snd this skill and are often of more use in exercise physiology research, where mechanistic investigations are often the focus rather than the Bsta-alanine recreation of a sporting setting.
Furthermore, exercise capacity tests are, by their very nature, maximal and will, therefore maximally stress the homeostasis of the internal environment. Exercise performance tests may not be maximal due to the use of pacing Beta-alaanine, be these consistent strategies which mask the effect of an intervention, or inconsistent strategies high-intensit increase variability.
It is possible that differences in the efficacy of β-alanine supplementation between performance and capacity tests and measures exist due to these factors.
Currently it would seem likely that the high-intensitu ergogenic mechanism by which β-alanine acts is through an elevation in carnosine synthesis within the muscle Harris Bea-alanine al. Readers are directed to the review articles of Sale et al.
The data in this meta-analysis clearly shows that exercise of a duration less than 60 s is not improved by β-alanine supplementation, while exercise of 60— s clearly is improved, and exercise over s is also improved, although to a lesser extent. However, it should be noted that, despite previous research suggesting that a reduced muscle pH did not affect performance of a single bout of 30 s maximal cycling Bogdanis et al.
Therefore, it is likely that the relationship shown by Suzuki et al. It is possible that, traoning area occupied by type II muscle fibres was more important to 30 s maximal sprint cycling than pH regulation directly. This meta-analysis supports the findings of Bogdanis et al. Therefore, other pathways related to β-alanine supplementation and the role of carnosine in the muscle, such as an effect of β-alanine on delaying the fatigue induced increase in ventilation rate Stout et al.
Stellingwerff in press recently published findings which demonstrate that as the dose of β-alanine supplemented increases, the duration of supplementation required to elicit changes in the muscle carnosine trainihg is reduced.
There is currently no known threshold to the storage of carnosine in muscle and therefore it would seem logical that the more β-alanine that is supplemented, be that at a lower dose over a longer duration or at a higher dose over a shorter duration, the more carnosine can be synthesised and stored in the muscle.
This could lead to a greater muscle buffering capacity during high-intensity exercise and therefore an improvement in exercise outcomes. Indeed, this theory is partially supported Brta-alanine the data of Hill et al.

Additionally, if supplementing with a non-time release version, consuming a total daily dose of 6 g would be important for augmenting muscle carnosine [ 40 ]. One particular study found that beta-alanine reduced acid build-up during high-intensity anaerobic exercise, which delayed fatigue. Bex T, Chung W, Baguet A, Stegen S, Stautemas J, Achten E, et al.
