The Claim

Creatine kinase (CK) undergoes liquid-liquid phase separation (LLPS) in skeletal muscle mitochondria under conditions of elevated phosphocreatine concentration (>25 mM), leading to the formation of dynamic condensates that enhance localized ATP regeneration rates by up to 9-fold during high-intensity exercise, thereby improving energy delivery efficiency to myofibrillar sites.

What the research says

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

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

How it works
1 study reviewed
In plain English

When your muscles work hard, a protein called creatine kinase can clump together in a special way inside energy factories (mitochondria), and this helps make energy faster right where it's needed — kind of like creating a pop-up power station in your muscle cells.

What the research says

1 study
  1. Study: Three-dimensional network of creatine metabolism: From intracellular energy shuttle to systemic metabolic regulatory switch

    The study agrees that creatine kinase can form droplet-like clusters in cells to help manage energy during exercise, but it doesn’t prove the exact conditions or how much faster energy is made, as claimed.
