Sodium Bicarbonate – Forschung

Was die Evidenz sagt
Hilft vermutlich
Sodium Bicarbonate half in etwa der Hälfte (5/9) der Studien, die einen Effekt gemessen haben — vielversprechend, aber nicht einhellig.
Die meiste Evidenz stammt aus hochwertigen Meta-Analysen und randomisierten Studien, veröffentlicht 1980–2026 mit einer typischen Studiengröße von 149 Teilnehmenden.

Einfach gesagt: Our results suggest, with moderate certainty, that sodium bicarbonate supplementation does not adversely affect systolic BP in CKD or negatively influence antihypertensive medication requirements.
Beynon-Cobb B et al. · Clinical journal of the American Society of Nephrology : CJASN (2023)
Similarly, there was no significant increase in the use of antihypertensive medication or diuretics in individuals taking sodium bicarbonate, whereas there was a greater decrease in antihypertensive medication use in individuals taking sodium bicarbonate compared with controls.
Our results suggest, with moderate certainty, that sodium bicarbonate supplementation does not adversely affect systolic BP in CKD or negatively influence antihypertensive medication requirements.
Einfach gesagt: Still, more well-designed research with elite soccer players is needed to improve support and advice regarding the use of dietary supplements for athletic performance enhancement.
Abreu R et al. · Journal of the International Society of Sports Nutrition (2023)
Nitrate-rich beetroot concentrate can attenuate performance decrease in the days following matches.
Further investigation with sodium bicarbonate alone is necessary, as supplementation protocols with elite players included other substances.
Finally, the available data does not support yohimbine supplementation or the use of Resurgex Plus® to improve athletic performance in elite soccer players.
Einfach gesagt: 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.
Einfach gesagt: These findings suggest NaHCO₃ enhances certain physiological responses but does not improve 200 m performance, though data limitations require cautious interpretation.
Huang D et al. · Research in sports medicine (Print) (2025)
Results showed significant increases in blood bicarbonate (SMD = 1.09, 95% CI = 0.38 to 1.79, P<0.01), blood lactate (SMD = 0.76, 95% CI = 0.24 to 1.29, P<0.01) and blood pH (SMD = 1.02, 95% CI = 0.33 to 1.71, P<0.01), but no effect on 200 m time (SMD = 0.26, 95% CI -0.58 to 1.10).
A comprehensive search across five databases identified eligible randomized controlled trials comparing NaHCO₃ with placebo.
Outcomes were 200 m time, blood bicarbonate, blood lactate, and blood pH.
