Sports nutrition for endurance training the realm Betta-alanine fitness and bodybuilding, the quest for optimal muscle growth is a pursuit that transcends the boundaries of conventional training. Amidst various supplements, Beta-Alanine has emerged as a potential game-changer, influencing muscle development in profound ways. Understanding the Role of Amino Acids in Muscle Development. Before delving into the specifics of Beta-Alanine, it's crucial to comprehend the foundational role amino acids play in muscle development. These building blocks of proteins serve as the groundwork for the intricate process of muscle synthesis.Beta-alanine and muscle hypertrophy -

The purpose of this study was to conduct a comprehensive analysis with various modeling techniques to synthesize existing knowledge about the MCarn response to BA supplementation. Collectively, our findings, based on all models employed, indicated that human skeletal muscle has large capacity for MCarn accumulation, and that commonly used protocols e.
Baseline values do not appear to influence subsequent response to supplementation and the non-linear response to supplementation was not influenced by sex. Analysis of individual data indicate that MCarn is relatively stable in the absence of intervention, and that effectually all Our analyses indicate humans have large capacity for non-linear MCarn accumulation in response to BA supplementation.
Figure 4 shows that BA supplementation can lead to a maximum effect size of ~3. Take, for example, the individual data set used in the current analysis, which had a baseline mean ± SD MCarn of Intake of 1, g of BA is estimated to lead to an approximate increase of three times this standard deviation, i.
It is important to highlight that these estimates are based on the median expected effect, and considerable inter-individual variation is likely.
Additionally, estimates at the higher end of the curve described in Figure 4 should be interpreted with caution, as a paucity of data based on very high doses limits precision regarding the point at which human skeletal muscle saturation occurs. Despite these caveats, our data provides new insight into the nature of the MCarn response to BA supplementation, and how this differs to other commonly used dietary supplements, such as creatine.
Response to creatine supplementation is largest in those with lowest baseline levels, whereas individuals whose creatine content is habitually closer to this saturation point gain smaller benefit from supplementation Harris et al.
In contrast, we observed no evidence that baseline MCarn influenced response to supplementation. This makes sense when considered in relation to our predictive model, as it seems that humans have large capacity to accumulate MCarn—far greater than is achieved with commonly used protocols e.
Our model indicates that MCarn increase in response to BA supplementation is non-linear, and that the greatest increases occur in the earlier stages of supplementation.
This finding aligns with a recent theoretical model proposed by Spelnikov and Harris , which describes absolute MCarn increases as a product of both synthesis and decay, with carnosine synthesis considered to be constant in relation to time and first order to daily BA dose.
Similarly, carnosine decay is also considered to be first order, but to relate to total MCarn content. As such, carnosine decay increases when absolute content is higher and so the rate of MCarn accumulation due to BA induced elevations in synthesis will slow, as illustrated in Figure 4.
Tissue saturation represents the point at which the rates of synthesis match decay, and so content remains constant despite continued supplementation. The exact point, and nature, of this saturation point is not currently known. Does human skeletal muscle have a largely uniform saturation point, after which no further increases can be attained as seems to be the case with creatine?
Or does capacity to accumulate MCarn vary widely between individuals, with each having their own upper limit? Currently, insufficient data using very high BA protocols on MCarn precludes the answering of this question, but one thing that is clear is that human skeletal muscle has large capacity to uptake BA and to increase MCarn, and that in the absence of intervention, MCarn is maintained at levels far below its maximal capacity.
The Emax model illustrated in Figure 4 clearly shows that very large amounts of BA are required to reach MCarn saturation. Theoretically, the greater the increase in MCarn content, the greater its ability to buffer, and to contribute to other processes such as anti-oxidation and anti-glycation, and so intuitively, attaining the largest increases possible seems desirable.
But evidence on this hypothesis is conflicting. Two individual studies reported that larger MCarn increases were associated with greater performance effects Hill et al. It would be counterintuitive to believe that performance benefits could linearly increase with ever-increasing MCarn, given that numerous factors, apart from acidosis, contribute to fatigue, and so it makes sense that at some point, performance benefits must plateau.
Identification of the lowest MCarn increase necessary to elicit an ergogenic effect, along with the point after which no further benefits can be obtained would have large potential to enhance the applicability and efficacy of BA supplementation strategies.
For example, it seems that the largest gains in MCarn are attained in the earlier phases of supplementation see Figure 4. It would be of interest to identify if strategies such as meal co-ingestion Stegen et al.
In addition to investigating whether or not greater MCarn increases are likely to bring about greater benefits, it is also important to weigh up the potential cons, against the potential pros, of this approach. From a practical point of view, dosing protocols of the magnitude required to cause saturation would be challenging.
Additionally, BA supplementation in its current doses is regarded as having no adverse effects Dolan et al. This sensation is not considered to be harmful but may be deemed unpleasant by some individuals. Paresthesia intensity is related to the timing of peak blood BA concentrations Harris et al.
Another theoretical adverse effect of prolonged BA supplementation is a decrease in taurine content, given that the two share a transporter Tau-T Shaffer and Kocsis, We have previously reported that very high BA doses namely those commonly used in animal trials result in a substantial depletion of intracellular taurine Dolan et al.
It is possible that the very high doses apparently required for MCarn saturation, may lead to taurine reductions, and so some caution must be taken in attempting to implement substantially higher doses than those currently in use. Similarly, previous research highlighted that L-histidine is also required for carnosine synthesis, and that chronic BA supplementation may cause depletion of the free histidine pool, which in itself may have implications given the wide range of physiological processes that histidine contributes to Blancquaert et al.
Similar to that which was observed for taurine, meta-analytic data indicated that BA dosing protocols within the ranges commonly used do not impact the free histidine pool Dolan et al. Collectively, the available evidence indicates that achieving the very high MCarn levels that the current Emax model indicates are possible, but may not be desirable, due to practical and safety issues.
We suggest that in lieu of investigating means of maximizing intracellular carnosine content, future research efforts should instead focus on the point at which maximum ergogenic benefits are attained, as well as the point after which no further ergogenicity occurs.
The current analysis also brought to light some interesting points about the nature of the MCarn response to supplementation, which has implications for future study design. In the absence of intervention, MCarn seems to be relatively stable, likely due to low intramuscular carnosinase and roughly equivalent synthesis and degradation rates Boldyrev et al.
Interestingly, both within and between study variance were large and similar. A large proportion of this sampling error is likely due to small sample sizes. Typically, the use of a control group would be recommended to normalize the effects of the intervention against those of usual biological variability Swinton et al.
This implies that the control group adds little value to the analysis, likely because of MCarn stability and the large effect of supplementation. In future investigations of the MCarn response to BA in young healthy males and particularly those for which resources are limited it may be prudent to direct resources toward the intervention group, in order to reduce within study variance.
It is important to note that this recommendation applies only to studies on the MCarn response to BA supplementation. The influence of BA supplementation on exercise performance, or clinical outcomes, is far less well-characterized and subject to substantially more sources of internal and external variability and so control groups are essential in studies for which exercise, or clinical effectiveness, is the primary outcome of interest.
In addition to characterizing the nature of MCarn response to BA supplementation, we also considered the influence of various potential moderators on this response.
In relation to the method of assessment, it seems that lower effect estimates are generally observed when MCarn is measured using the H-MRS technique when compared to those obtained using HPLC analysis of muscle biopsies.
Only one study showed no MCarn increase, despite using a commonly used dosing protocol of 6. It is important to highlight that the MRS measurements reported in that study used a 1.
Given the incongruency of this finding in comparison to all others, it seems plausible that this may have occurred due to methodological inadequacies.
When considering the influence of non-modifiable factors on the MCarn response to supplementation namely age and sex , we could not conduct analyses on the influence of age, as insufficient data in older groups, and no data on younger groups, were available.
Further research investigating the influence of BA supplementation on MCarn in older adults, along with potential therapeutic or ergogenic benefits, would be of interest, although it is worth highlighting that the one study that investigated a group aged 60—80 years did show comparable increases to other studies conducted in younger populations del Favero et al.
Women have previously been reported to have lower MCarn than men Mannion et al. Despite these differences, our data indicate that both men and women have a similar response to BA supplementation, indicating that the lower values previously reported in women are unlikely to relate to an inherent gender dysmorphism in the biological factors that underpin carnosine metabolism.
In conclusion, our findings indicate that human skeletal muscle has large capacity to accumulate carnosine. MCarn remains stable in the absence of intervention and neither low baseline MCarn levels, nor sex, influence the subsequent response to BA supplementation.
In turn, these findings lead to other questions, the response to which may have large implications for future practice.
From the point of view of athletic performance, key questions include: what is the absolute MCarn increase required to elicit an ergogenic effect, along with the point after which no further benefits are attained?
It is clear that 4 weeks of BA supplementation can be ergogenic, but can this be achieved earlier? Can strategies to enhance the early response to BA supplementation meaningfully impact the subsequent ergogenic benefits? The response to these questions may progress practical application of this supplementation strategy, with potential benefit to many athletic and clinical populations.

The recommended dosage of beta-alanine is 5 grams per day. However, taking more than 5 grams per day can lead to side effects such as paresthesia, a tingling sensation in the skin.
This side effect is harmless and temporary, but can be uncomfortable for some people. Beta-alanine is a natural and effective way to enhance athletic performance and promote muscle growth. By increasing the levels of carnosine in the muscles, beta-alanine can help delay fatigue, reduce muscle soreness, and lead to increased muscle growth.
Beta-alanine works well with other supplements such as creatine and whey protein, which can enhance its benefits even further. Buying raw beta-alanine from your supplement brand can also be a cost-effective option for those who want to customize their dosage and save money.

Muscle carnosine concentration is also linked with having a high percentage of Type II fast-twitch muscle fibers. For this reason, you'll find higher levels of muscle carnosine among Calorie counting for weight gain and natural muscle freaks.
Men also generally have higher muscle carnosine concentrations than ahd, most Beta-alahine because the Beta-lanine that breaks ahd carnosine is more active in women.
You derive Sports nutrition for endurance training free-form beta-alanine Beta-aalanine the foods you consume. Most comes in ad form of the dipeptides carnosine, anserine or balenine, Beta-alaninee of which contribute to raising beta-alanine availability when broken down during digestion.
Unless you are vegetarian, annd derive these from the animal hyperrtophy in your diet. Specifically, pork and beef Cognitive function improvement good sources of Betq-alanine, whereas tuna and venison are high food sources of qnd.
Just how tied is carnosine to being a carnivore? Well, carnosine synthase the enzyme that produces carnosine expression has been shown to be significantly reduced in response to just five weeks of a vegetarian diet. As you might expect from that, muscle carnosine concentrations are significantly lower in vegetarians than in the muscles of their carnivorous or omnivorous counterparts.
Beta-alanine is also a standard ingredient in many pre-workout supplements, in addition to being available on its own. When purchasing a beta-alanine supplement, however, look for the brand name CarnoSyn® on the label. Natural Alternatives International, Inc. is the patent-holder on the manufacturing process by which beta-alanine is made, and its product is the only one protected by use patents and is the one that has been suggested to be effective in repeated research trials.
Buyer, be wary if you don't see CarnoSyn® on the label! You may instead just be consuming regular L-alanine or something altogether different.
If you're looking for a boost in short-to-medium duration high-intensity muscle performance, few supplements to date have fit the bill as consistently as beta-alanine. Specifically, beta-alanine seems most effective for supporting exercise lasting longer than 60 seconds.
It has not been shown to be significantly or consistently effective in shorter duration bouts of exercise, where the ATP-phosphocreatine energy system is in highest demand. 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 monohydratemg of beta-alanine four times per day, or the same dose of beta-alanine plus 20 g of creatine monohydrate.
Maximal power output in a four-minute all-out cycling test was significantly increased in the two groups receiving beta-alanine, versus those receiving the placebo or only creatine.
The most significant improvement was noted in the first and fourth minutes of cycling. Four weeks of six grams per day of bata-alanine increased the punch force of amateur boxers by an amazing 20 times. Since that early trial, beta-alanine has been consistently suggested to increase muscle power output, strength, training volume, high-intensity exercise performance and peak oxygen uptake aerobic capacity.
Most recently, when players consumed 3. In fact, when all subject responses were analyzed, those consuming beta-alanine improved by a range of 0 to Similarly, researchers out of the U. presented evidence that just four weeks of six grams per day of beta-alanine 1.
However, when long rest periods minutes were provided between sets of a high-intensity strength training session, the effects of beta-alanine were insignificant.
Therefore, for the effects of beta-alanine to be most noticeable, I would recommend a high-intensity bodybuilding-style training program, HIIT or interval training, CrossFit, or all-out minute bouts to exhaustion, with short rest periods of less than 2 minutes.
Beta-alanine can provide an acute stimulant response and is therefore a good candidate for being consumed pre-workout. If you take a pre-workout supplement, you might already be taking it this way.
However, the performance benefits from beta-alanine are based upon raising muscle carnosine concentrations over time. Thus, the time of day you consume beta-alanine isn't nearly as important as consistently consuming beta-alanine each day. Your muscle fiber makeup and the amount of muscle carnosine you have when you start supplementing with beta-alanine do not appear to impact how you will respond to supplementation.
Likewise, the size of individual doses doesn't appear to affect the maximal concentration of muscle carnosine that you can achieve. Instead, the total dose over a period of time affects the final muscle carnosine concentration that you can achieve.
The dose response to beta-alanine increases exponentially over time because of the long clearance time of elevated muscle carnosine concentrations. Once you build up your carnosine concentration with beta-alanine, those elevated levels have been shown to drop by just two percent every two weeks after you cease supplementing.
I recommend consuming taurine when supplementing with beta-alanine. Not only is taurine an underutilized super-nutrient, it's also incredibly important for neuromuscular, cognitive and lung function, blood glucose utilization, and as an antioxidant.
Since beta-alanine and taurine compete for uptake and the concentration of one affects the other, consuming one of them consistently while dosing the other is just common sense.
If common sense isn't enough for you, then let's get specific. Over the long term, there is a possibility that high-dose beta-alanine use in the absence of dietary taurine may lead to health and performance complications. Data in mice seem to indicate that pushing either supplement in the absence of the other can lead to neurological and neuromuscular decreases in performance tests.
With beta-alanine, the result was an angiogenic stress-inducing response as serotonin production was compromised.
Other research in rats seems to indicate that significant taurine deficiency, in response to chronic, high-dose beta-alanine, reduces nitric oxide production and response. However, no long-term studies have been conducted to determine the likelihood of such problems with humans in response to typical beta-alanine dosing.
Aside from taurine, what you choose to stack with beta-alanine will depend most upon your goals. Remember, beta-alanine works best when exercise is of a high-intensity and lasts at least minutes.
So if your goal is exercise improvement for sessions lasting less than 60 seconds, aim for ingredients that support the ATP-PCr energy system. These include creatine, oral ATPcaffeine, and betaine. If you are training for sports, then also consider adding ingredients such as DL-malate and similar energy system intermediates such as alpha-ketoglutarate, citrates, aspartates, in addition to carbohydrates, BCAAsglutaminecitrulline, and Co-Q Based upon the available data, I don't see a need for cycling beta-alanine, as long as you're also supplementing with taurine.
If you're not consuming supplemental taurine, then it may be prudent to cycle your beta-alanine every so often. Since taurine uptake is only affected by rises in plasma beta-alanine, and because muscle carnosine remains elevated for up to three months after ceasing beta-alanine supplementation, a weeks "on" to weeks "off" cycling strategy should allow you to consistently reap the performance benefits of beta-alanine.
However, this is just conjecture on my part, and it's a moot point if you just supplement with taurine. Beyond that point, it's unclear if muscle carnosine concentrations will continue to rise, or if a ceiling is eventually reached. Additionally, since the clearance time of muscle carnosine is so slow, more research needs to be performed to determine what carnosine concentration increases are necessary to observe significant improvements in performance.
To put it another way: Is an 80 percent increase in muscle carnosine any more effective than a 50 percent increase? Also, is cycling beta-alanine helpful or necessary after a certain threshold of muscle carnosine concentration has been achieved?
Until we have answers to these questions, we can only suggest general guidelines over the long-term. Beta-alanine comes with its own built-in dosing regulator. You might recall feeling it in your neck or arms the first time you tried a pre-workout supplement that contained beta-alanine.
The scientific name for this "pins and needles" feeling is acute paresthesia. It can also produce a burning, itching, or flushed feeling on the scalp or ears. Beta-alanine doses greater than about mg-less than half of the amount contained in a single scoop of some popular pre-workouts-have generally been reported to cause moderate to severe paresthesia lasting minutes.
In one study, in which subjects consumed 3 grams of beta-alanine in one dose, the parasthesia effect was reported as significant and severe.
If paresthesia is a concern, then I would recommend you limit your initial consumption to no more than about mg of beta-alanine, every hours, for at least four weeks. This will be sufficient to derive the supplement's performance benefits and your reaction to its use.
If you take beta-alanine on an empty stomach, blood concentrations will indeed increase faster, but you're also more likely to experience the paresthesia side effects. Additionally, consumers who use beta-alanine for its stimulant response tend to report more consistent effects when they consume it on an empty stomach.

| SYSTEMATIC REVIEW article | Beta-alanine could earn a permanent place in your nutritional war-chest. I'm here to provide you the science-based intel you need to decide if it's right for you. Beta-alanine claims to raise muscle carnosine levels and increase the amount of work you can perform at high intensities. Beta-alanine, or 3-aminopropionic acid is a naturally-occurring beta-amino acid and a component of the histidine dipeptides carnosine and anserine, as well as vitamin B5 , or pantothenic acid.

Beta-alanine is even gaining support within the scientific community for being secondarily classified as a neurotransmitter. Your body can produce beta-alanine in at least three ways. It can be released during the breakdown of histidine dipeptides, such as carnosine or anserine, or it can be formed as a secondary byproduct of a reaction that converts L-alanine to pyruvate. Additionally, beta-alanine can be formed during digestion, when intestinal microbes remove a carbon atom from L-aspartate, releasing both beta-alanine and CO2. But don't tell Al Gore that, or he'll try to argue that you should be charged for increasing your carbon footprint. 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. That's where the fun really begins.

When purchasing a beta-alanine supplement, however, look for the brand name CarnoSyn® on the label. Natural Alternatives International, Inc. is the patent-holder on the manufacturing process by which beta-alanine is made, and its product is the only one protected by use patents and is the one that has been suggested to be effective in repeated research trials. Buyer, be wary if you don't see CarnoSyn® on the label! You may instead just be consuming regular L-alanine or something altogether different. If you're looking for a boost in short-to-medium duration high-intensity muscle performance, few supplements to date have fit the bill as consistently as beta-alanine. Specifically, beta-alanine seems most effective for supporting exercise lasting longer than 60 seconds. It has not been shown to be significantly or consistently effective in shorter duration bouts of exercise, where the ATP-phosphocreatine energy system is in highest demand. 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 , mg of beta-alanine four times per day, or the same dose of beta-alanine plus 20 g of creatine monohydrate. Maximal power output in a four-minute all-out cycling test was significantly increased in the two groups receiving beta-alanine, versus those receiving the placebo or only creatine. The most significant improvement was noted in the first and fourth minutes of cycling. Four weeks of six grams per day of bata-alanine increased the punch force of amateur boxers by an amazing 20 times. Since that early trial, beta-alanine has been consistently suggested to increase muscle power output, strength, training volume, high-intensity exercise performance and peak oxygen uptake aerobic capacity. Most recently, when players consumed 3. In fact, when all subject responses were analyzed, those consuming beta-alanine improved by a range of 0 to Similarly, researchers out of the U. presented evidence that just four weeks of six grams per day of beta-alanine 1. However, when long rest periods minutes were provided between sets of a high-intensity strength training session, the effects of beta-alanine were insignificant. Therefore, for the effects of beta-alanine to be most noticeable, I would recommend a high-intensity bodybuilding-style training program, HIIT or interval training, CrossFit, or all-out minute bouts to exhaustion, with short rest periods of less than 2 minutes. Beta-alanine can provide an acute stimulant response and is therefore a good candidate for being consumed pre-workout. If you take a pre-workout supplement, you might already be taking it this way. However, the performance benefits from beta-alanine are based upon raising muscle carnosine concentrations over time. Thus, the time of day you consume beta-alanine isn't nearly as important as consistently consuming beta-alanine each day.
