The Claim

Creatine supplementation enhances the sensitivity of colorectal tumors to anti-PD-1 immunotherapy in animal models.

Source: SLC6A8-mediated creatine uptake suppresses ERK2-FSP1 signaling and induces ferroptosis in colorectal cancer.

Roughly balanced

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

In plain English

In animal models, taking creatine supplements increases the effectiveness of anti-PD-1 immunotherapy in reducing colorectal tumor growth.

See the scientific wording

Creatine supplementation sensitizes colorectal tumors to anti-PD-1 immunotherapy in animal models.

Why this might work

Creatine enters cancer cells and blocks a protein that normally protects them from a type of cell death caused by fat damage. When this protection is removed, the cancer cells die from fat damage, releasing signals that attract immune cells. These immune cells then attack the tumor more effectively when a drug that removes immune system brakes is given.

  1. Study: SLC6A8-mediated creatine uptake suppresses ERK2-FSP1 signaling and induces ferroptosis in colorectal cancer.

    In mice with colon cancer, adding creatine to their diet helped their immune system fight the tumor better when given a special cancer drug (anti-PD-1), making the drug work more effectively.
