The Claim

Fisetin supplementation at 200 mg/day for 12 weeks without concurrent exercise reduces interleukin-6 by 8.8% and tumor necrosis factor-alpha by 36.1% in obese men, and has no significant effect on Maresin-1 levels or insulin sensitivity compared to placebo.

In plain English

In obese men, taking 200 mg of fisetin daily for 12 weeks without exercise lowers interleukin-6 by 8.8% and tumor necrosis factor-alpha by 36.1%, but does not change Maresin-1 levels or insulin sensitivity more than a placebo.

See the scientific wording

Fisetin supplementation (200 mg/day) for 12 weeks without exercise reduces interleukin-6 by 8.8% and tumor necrosis factor-alpha by 36.1% in obese men, but does not significantly increase Maresin-1 or improve insulin sensitivity beyond placebo levels.

Why this might work

Fisetin blocks a key inflammation switch in fat and immune cells, which stops the production of harmful signaling molecules. It also protects essential fats from damage, allowing the body to naturally calm inflammation without needing exercise.

  1. Study: 12‑weeks fisetin supplementation and interval resistance with aerobic training: changes in Maresin‑1 and inflammatory markers in men with obesity: a randomized controlled trial

    The study found that taking fisetin alone, even without exercise, lowered inflammation and improved insulin sensitivity — but the claim says it doesn’t. So the claim is wrong.
