The Claim

The combination of beta-alanine and creatine monohydrate does not produce greater improvements in aerobic endurance metrics than either supplement alone in healthy young men over a 28-day period.

Source: Effects of 28 days of beta-alanine and creatine monohydrate supplementation on aerobic power, ventilatory and lactate thresholds, and time to exhaustion

Support is ahead, but a single strong opposing study can change this.

In plain English

Taking beta-alanine and creatine monohydrate together does not lead to better aerobic endurance gains than taking either supplement by itself in healthy young men after 28 days.

See the scientific wording

The combination of beta-alanine and creatine monohydrate does not produce greater improvements in aerobic endurance metrics than either supplement alone in healthy young men over a 28-day period.

Why this might work

Taking both supplements together doesn't improve endurance more than either alone because the body's ability to buffer acid and supply energy during prolonged exercise reaches its maximum limit with one supplement, and adding the second doesn't push it further.

  1. Study: Effects of 28 days of beta-alanine and creatine monohydrate supplementation on aerobic power, ventilatory and lactate thresholds, and time to exhaustion

    The study found that taking both supplements together didn’t help young men last longer on a bike test any better than taking just one of them — or even taking a sugar pill. So, combining them didn’t give extra benefits.
