1Strength and power performanceSystematic ReviewCited 1×n=197 · medium study2025
β-alanine supplementation should emphasize fragmented dosing protocols of 4-6.4 g/day sustained over 5-8 weeks, particularly when implemented during training phases characterized by high metabolic stress
Ong SW et al. · Journal of the International Society of Sports Nutrition (2025)
Nine studies comprising 197 participants were reviewed.
Daily β-alanine doses between 4 g and 6.4 g, especially when divided into multiple smaller servings, were more likely to enhance maximal strength and power-related outcomes.
Cumulative dose and delivery method may play a more critical role than duration alone in promoting strength and power adaptations.
3Cycling performanceSystematic ReviewCited 5×n=701 · large study2024
However, no statistically significant effects were identified for the remaining supplements, whether administered individually or in combination.
Valiño-Marques A et al. · Nutrients (2024)
However, no statistically significant effects were identified for the remaining supplements, whether administered individually or in combination.
Thirty-six articles involving 701 participants were included in this review, examining supplementation with caffeine (n = 5), creatine (n = 2), sodium bicarbonate (n = 6), beta-alanine (n = 3), and nitrates (n = 8).
Additionally, supplemental combinations of caffeine and creatine (n = 3), caffeine and sodium bicarbonate (n = 3), caffeine and nitrates (n = 1), creatine and sodium bicarbonate (n = 1), and sodium bicarbonate and beta-alanine (n = 4) were analyzed.
5High-intensity exercise performanceSystematic ReviewCited 4×n=263 · medium study2025
Conclusions: The combination of creatine and β-alanine supplementation may be effective for enhancing high-intensity exercise performance but has no greater effect on maximal strength, body composition, or measures of aerobic capacity compared to creatine or β-alanine alone.
Ashtary-Larky D et al. · Nutrients (2025)
The effects of creatine and β-alanine supplementation on body composition were equivocal, with one study reporting greater lean mass gains and fat mass reductions compared to creatine and β-alanine supplementation individually, while another found no significant improvements.
Additionally, no significant improvements in aerobic endurance capacity (VO2max, lactate threshold, or time to exhaustion) were observed from creatine and β-alanine supplementation co-ingestion.
Co-ingestion of creatine and β-alanine supplementation did not increase measures of maximal strength compared to creatine alone.
6Maximal intensity exercise performanceMeta-AnalysisCited 4×n=331 · medium study2024
A significant (p = .01) result was observed with an overall effect size of 0.39 (95% confidence interval [CI] [0.09, 0.69]), in favor of beta-alanine supplementation versus placebo.

A total of 18 individual studies were analyzed, employing 18 exercise test protocols and 15 outcome measures in 331 participants.
Significant effects at a high beta-alanine dosage of 5.6-6.4 g per day, effect size 0.35 (95% CI [0.09, 0.62], p = .009).
4-10 min of maximal effort showed effect size 0.55 (95% CI [0.07, 1.04], p = .03).
Overall, exercise capacity may be improved following supplementation protocols with dosages ranging from 2.4 to 3.2 g/day.
de Camargo JBB et al. · Journal of aging and physical activity (2025)
Overall, exercise capacity may be improved following supplementation protocols with dosages ranging from 2.4 to 3.2 g/day.
Muscle strength and functional performance do not seem to be improved by beta-alanine since these tasks are not significantly impacted by acidosis buildup.
17Athletic performance in soccer playersMeta-AnalysisCited 6×2025
This study suggests that a range of dietary supplements, including caffeine, creatine, creatine + sodium bicarbonate, magnesium creatine chelate, carbohydrate + electrolyte, carbohydrate + protein, arginine, beta-alanine, bovine colostrum, Kaempferia parviflora, melatonin, and sodium pyruvate, can improve athletic performance in soccer players.
Luo H et al. · Journal of the International Society of Sports Nutrition (2025)
Kaempferia parviflora (SMD: 0.46, small) was associated with a significant effect on enhancing muscular strength.
Beta-alanine (SMD: 0.83, moderate), melatonin (SMD: 0.75, moderate), caffeine (SMD: 0.37, small), and creatine (SMD: 0.33, small) were associated with a significant effect on enhancing jump height.
Magnesium creatine chelate (SMD: -3.0, very large), melatonin (SMD: -1.9, large), creatine + sodium bicarbonate (SMD: -1.4, large), and arginine (SMD: -1.2, moderate) were associated with a significant effect on decreasing sprint time.

Creatine supplementation demonstrated ergogenic benefits for competitive swimmers, although the evidence supporting the use of this supplement is still limited.

This revision included 23 studies, 16 of them (69.6%) qualified as excellent and 7 (30.4%) as good at the methodological level based on the punctuation in the PEDro scale.
The systematic review included 422 swimmers (61.8% male, 38.2% female), with distances assessed ranging from 50 m to 800 m, including studies employing interval procedures.
Creatine showed a significant effect (ES = -0.46; 95% CIs = -0.75 to -0.17, p = 0.002; I2 = 11%) on swimming performance, while the rest of the analyzed supplements did not show significant effects (all p > 0.05).

According to the results of the studies reviewed, we would recommend β-A and SB co-supplementation during high intensity exercises lasting between 30 s and 10 min.
Gilsanz L et al. · Critical reviews in food science and nutrition (2023)
Nine studies including a total of 221 athletes were identified for review.
Athletes were supplemented with β-A and SB while they performed exercise tests to assess physical performance and buffer capacity.
Five of the nine studies indicated there was some additional improvement in buffering capacity and performance with co-supplementation, while one study concluded that the effect was comparable to the added effects of the individual supplements.
This meta-analysis study suggests that beta-alanine supplementation is unlikely to improve body composition indices regardless of supplementation dosage and its combination with exercise training.
Ashtary-Larky D et al. · Journal of the International Society of Sports Nutrition (2022)
This meta-analysis study suggests that beta-alanine supplementation is unlikely to improve body composition indices regardless of supplementation dosage and its combination with exercise training.
No studies have examined the effect of beta-alanine combined with both diet and exercise on body composition changes as the primary variable.
