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.

Read this first

An evidence index, not guidance.

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.

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.

No additive effect of creatine, caffeine, and sodium bicarbonate on intense exercise performance in endurance-trained individuals.

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.”

Moesgaard et al. · Authors' conclusion

Names both Creatine and Sodium Bicarbonate in its title.

Short-term co-ingestion of creatine and sodium bicarbonate improves anaerobic performance in trained taekwondo athletes.

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.”

Sarshin et al. · Authors' conclusion

Names both Creatine and Sodium Bicarbonate in its title.

Effects of Creatine and Sodium Bicarbonate Coingestion on Multiple Indices of Mechanical Power Output During Repeated Wingate Tests in Trained Men.

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.”

Griffen et al. · From the abstract

Names both Creatine and Sodium Bicarbonate in its title.

Combined creatine and sodium bicarbonate supplementation enhances interval swimming.

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.”

Mero et al. · From the abstract

Names both Creatine and Sodium Bicarbonate in its title.

Effects of combined creatine and sodium bicarbonate supplementation on repeated sprint performance in trained men.

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.”

Barber et al. · From the abstract

Names both Creatine and Sodium Bicarbonate in its title.

The effect of multi-ingredient intra- versus extra-cellular buffering supplementation combined with branched-chain amino acids and creatine on exercise-induced ammonia blood concentration and aerobic capacity in taekwondo athletes.

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.”

Durkalec-Michalski et al. · Authors' conclusion

Names Creatine and Sodium Bicarbonate together in an interaction, co-administration, or pharmacokinetic context.

The effects of different hydration strategies before endovascular treatments to the renal function of the arteriosclerosis obliterans patients

Zhonghua yi xue za zhi · 2010 · PMID 20646558

Comparative StudyHuman subjects

“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.”

Zhu et al. · Authors' conclusion

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:

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Creatine, Sodium Bicarbonate, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
