Should You Stack Creatine and ß-Alanine for Better Workout Results?

Combining creatine and β-alanine may improve repeated high-intensity efforts but adds little benefit over creatine alone for strength, endurance, or body composition.

Highlights:

Stacking creatine with β-alanine improved repeated sprint performance but not maximal strength or endurance
No consistent body composition benefits were found from co-supplementation
The combination may benefit specific training goals like HIIT or combat sports

Creatine and β-alanine are two of the most widely studied sports supplements, each supporting performance through different biological pathways. Creatine monohydrate helps regenerate ATP, the energy currency of muscle cells, allowing for explosive movements like heavy lifting and sprinting ().

β-alanine, on the other hand, boosts levels of carnosine, a compound that buffers acid buildup in muscles during high-intensity exercise. This helps delay fatigue in efforts lasting one to four minutes, such as circuit training or combat drills.

Together, these two supplements work on complementary systems: creatine supports energy bursts, while β-alanine helps muscles recover between them. That has led to the theory that combining them might produce a "synergistic effect", but does the science back that up?

Creatine Supplementation – Yes or No?
What is creatine? It is a food constituent, which is found in muscle tissue and derived from animal sources. Creatine is an ergogenic aid used to enhance sports performance by increasing energy production.

What Did Researchers Study?

A recent systematic review published in Nutrients sought to answer whether stacking creatine and β-alanine leads to better exercise outcomes than taking either supplement alone. Out of 5,537 publications screened, researchers included seven randomized controlled trials (RCTs) involving 263 participants (231 men and 32 women).

Studies included had to administer the supplement combination for at least four weeks and assess outcomes such as anaerobic power, strength, endurance, or body composition.

Due to variability in study designs, populations, and protocols, a meta-analysis was not possible. Instead, researchers provided a qualitative synthesis of the findings.

Is Creatine the Secret Sauce for Everyone?
Creatine is more than a muscle-builder—it's safe, science-backed, and supports brain, muscle, and overall health across all ages.

What the Studies Revealed

1. High-Intensity Performance Improved
Studies focusing on repeated sprint or anaerobic power tasks found that co-supplementation improved mean power output and reduced fatigue. For instance, in repeated Wingate cycling tests, the creatine + β-alanine combo outperformed creatine alone in sustaining power across multiple sprints.

2. No Extra Gains in Strength or Endurance
The combo didn't outperform creatine alone when it came to one-rep max strength, VO₂ max, or endurance tests like time-to-exhaustion. Creatine remained the primary driver of strength gains.

3. Mixed Results on Body Composition
One 10-week study in trained males found that co-supplementation led to slightly greater lean mass gains and fat loss. However, a 4-week study in females showed no such benefit. Overall, the data was inconclusive.

4. Individual Differences May Matter
Response to these supplements may depend on genetics, baseline diet (e.g., vegetarianism), or training style. For example, female participants engaging in endurance training didn’t see the same anaerobic benefits as males focused on resistance training.

Think Fat Loss With Creatine and Resistance Training
Researchers found that resistance training combined with creatine supplements enhanced fat loss in adults under the age of 50.

When Could This Supplement Stack Be Useful?

The review suggests that this combo may be ideal for athletes whose sports rely on repeated bursts of high-intensity output, like sprinters, combat athletes, or HIIT participants, where both energy replenishment and fatigue buffering matter.

However, for those aiming purely to increase strength, muscle mass, or endurance, creatine alone appears to provide most of the benefits. β-alanine adds little for these specific goals.

What We Still Don’t Know About This Supplement Stack

This area of research is still in its early stages. The seven RCTs analyzed had different protocols, and most enrolled small sample sizes. There’s also a lack of standardized dosing strategies; studies used β-alanine doses ranging from 3.2 to 6.4 grams/day and varied creatine protocols (with or without loading phases).

Additionally, only one study focused solely on female participants, limiting conclusions about sex-specific responses. Further large-scale trials are needed to confirm long-term effects and clarify whether co-supplementation provides meaningful advantages across different training styles.

Should You Add This Combo to Your Supplement Stack?

For athletes pushing their limits in repeated sprints or rounds, think HIIT, circuit training, or combat sports, the combination of creatine and β-alanine may provide an added edge. The extra stacking cost may not offer much payoff for others, especially those focused on raw strength.

As always, please consult a healthcare or sports nutrition professional before starting any new supplement routine, and pair it with a solid training plan and balanced nutrition.
