Creatine vs beta-alanine: how do they differ?

How they work · Evidence · Study amounts · Side effects

Short answer: Creatine has more consistent evidence: NIH says it often raises strength and power in repeated short, hard efforts, while results for beta-alanine are mixed.1 A meta-analysis of 40 beta-alanine studies found a small benefit, mostly in exercise lasting 30 seconds to 10 minutes.2 Creatine can add water weight; beta-alanine can cause harmless tingling.1

How do creatine and beta-alanine compare side by side?

From the NIH Office of Dietary Supplements exercise fact sheet and a 2017 meta-analysis.
CreatineBeta-alanine
How it worksRaises phosphocreatine stores that supply quick energy at the start of intense exercise1Raises muscle carnosine, which buffers acid build-up during hard exercise1
Made by the bodyAbout 1 g a day by the liver and kidneys1Made in the liver; diet supplies none (vegans) to about 1 g a day1
Evidence summary (NIH)Many trials generally showing benefit for high-intensity, intermittent activity; little value for endurance1Many trials with conflicting results; little or no benefit beyond 10 minutes1
Amounts used in studies20 g a day for 5 to 7 days then 3 to 5 g a day, or 3 to 6 g a day for 3 to 4 weeks14 to 6 g a day for 10 weeks raised muscle carnosine up to 80%1
Main side effectWeight gain from water held in muscle, 1 to 2 kg in a month in strength programs1Tingling (paresthesia) for 60 to 90 minutes after 800 mg or more at once1
Safety range in NIH summaryFew concerns at typical doses; several years of use reported safe11.6 to 6.4 g a day for up to 8 weeks; no data beyond 1 year1

What does the evidence show?

Creatine: NIH says 5 to 7 days of creatine often raises strength and power in repeated maximal efforts like bench presses, cycling sprints and soccer, but it seems to be of little value for distance running or swimming. Vegetarians, who have less creatine in muscle, may respond more.1

Beta-alanine: a 2017 meta-analysis of 40 placebo-controlled studies (1,461 people) found a small overall effect (effect size 0.18), mainly in exercise lasting 30 seconds to 10 minutes.2 NIH notes a Department of Defense-sponsored review of 20 trials did not support it for active adults, and that experts have not agreed on its value.1

The sources here studied each supplement on its own against placebo, not against each other. These are study protocols, not personalized advice; confirm any dosing with your prescriber.

What side effects should you expect?

  • Creatine: weight gain from water is the most consistent effect. Anecdotal reports include nausea, diarrhea, cramps and heat intolerance. It breaks down into creatinine, which the kidneys clear.1
  • Beta-alanine: single servings of 800 mg or more, or over 10 mg per kg of body weight, can cause tingling in the face, neck, hands and upper body for 60 to 90 minutes. NIH says it is not harmful, and smaller divided servings reduce it.1

Frequently asked questions

Which works better, creatine or beta-alanine?+
They have not been compared head to head in the sources checked here. NIH describes creatine's results as generally positive for short, intense efforts and beta-alanine's as conflicting.1
Why does beta-alanine make my skin tingle?+
Servings of 800 mg or more can cause paresthesia, a tingling that lasts 60 to 90 minutes. NIH says it is not harmful and divided servings reduce it.1
Does creatine make you gain weight?+
Often, mostly water in muscle. NIH cites a 1 to 2 kg rise in a month with a strength-training program.1
Is creatine monohydrate the best form?+
NIH says other forms, such as creatine ethyl ester or buffered creatine, have not been shown to work better than monohydrate.1
Can I track creatine and beta-alanine in Dose Track?+
Yes. Both are in the library; log daily grams with reminders.
