The Claim

In young, healthy males, the co-ingestion of 5 g creatine with a mixture of 14 g protein hydrolysate, 7 g leucine, 7 g phenylalanine, and 57 g dextrose stimulates insulin release to a similar extent as 5 g creatine with 95 g dextrose, and both combinations reduce urinary creatine excretion compared to creatine ingested with water alone.

Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

If young, healthy guys take creatine with a mix of sugar, protein bits, and certain amino acids, it triggers about as much insulin as taking creatine with just a lot of sugar — and both help the body hold onto more creatine than if they took it with water.

What the research says

1 study
  1. Study: Optimization of insulin-mediated creatine retention during creatine feeding in humans

    The study found that mixing creatine with a blend of protein, amino acids, and sugar boosted insulin and kept more creatine in the body just as well as mixing it with a lot of sugar alone.
