Creatine and Sodium Bicarbonate: what the published research says
PubMed indexes 8 records that name Creatine and Sodium Bicarbonate together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to Creatine and Sodium Bicarbonate. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
A study appearing here is not proof that an interaction exists. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
NutriStack’s own interaction assessment for this pair is not published here. It has not completed qualified-human clinical review, so it is withheld from search. See the publication gate.
Nothing here is medical advice. Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen.
The research
8 studies naming Creatine and Sodium Bicarbonate.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
Scandinavian journal of medicine & science in sports · 2024 · PMID 38646853
Randomized Controlled Trial
“While creatine and caffeine can enhance sprint- and time trial performance, respectively, these effects do not seem additive. Therefore, supplementing with either creatine or caffeine appears sufficient to enhance sprint or short intense exercise performance.”
Names both Creatine and Sodium Bicarbonate in its title.
Journal of the International Society of Sports Nutrition · 2021 · PMID 33478522
Randomized Controlled Trial
“Short-term CR and SB alone enhance TAIKT performance in trained taekwondo athletes. Co-ingestion of CR and SB augments MP compared to CR and SB alone, with similar PP improvements.”
Names both Creatine and Sodium Bicarbonate in its title.
International journal of sport nutrition and exercise metabolism · 2015 · PMID 25203421
Randomized Controlled Trial
“Fatigue index (W·s(-1)) was impaired in all conditions compared with placebo. In conclusion, there was no meaningful additive effect of creatine and sodium bicarbonate coingestion on mechanical power during repeated sprints.”
Names both Creatine and Sodium Bicarbonate in its title.
Journal of strength and conditioning research · 2004 · PMID 15142001
Clinical TrialRandomized Controlled Trial
“Mean blood lactate increased (p < 0.001) during the swims, but there were no differences in peak blood lactate between the combination group (14.9 +/- 0.9 mmol.L(-1)) and placebo (13.4 +/- 1.0 mmol.L(-1)). The data indicate that simultaneous supplementation of creatine and sodium bicarbonate enhances performance in consecutive maximal swims.”
Names both Creatine and Sodium Bicarbonate in its title.
Journal of strength and conditioning research · 2013 · PMID 23254493
Human subjects
“Combining creatine and sodium bicarbonate supplementation increased peak and mean power and had the greatest attenuation of decline in relative peak power over the 6 repeated sprints. These data suggest that combining these 2 supplements may be advantageous for athletes participating in high-intensity, intermittent exercise.”
Names both Creatine and Sodium Bicarbonate in its title.
Journal of the International Society of Sports Nutrition · 2021 · PMID 34127014
Randomized Controlled Trial
“In highly trained taekwondo athletes, neither extra- nor intracellular buffering enhancement resulting from BA and ALK supplementation, combined with BCAA and TCM treatment, affects body mass and composition, maximum oxygen uptake, and hematological indices, even though certain advantageous metabolic adaptations can be observed.”
Names Creatine and Sodium Bicarbonate together in an interaction, co-administration, or pharmacokinetic context.
“Sodium chloride provides a good efficacy for preventing the adverse effect of contrast medium to the renal function of the ASO patients. For the patients pre-existing renal dysfunction, Combination hydration with sodium bicarbonate is not more effective than normal saline alone in preventing contrast-induced renal dysfunction.”
Names Creatine and Sodium Bicarbonate together in an interaction, co-administration, or pharmacokinetic context.
Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.
