The Claim
Inactive reverse triiodothyronine (rT3) competitively binds to thyroid hormone receptors without triggering cellular activation, effectively reducing functional thyroid hormone availability and suppressing metabolic rate.
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.
A substance called rT3 blocks your body's active thyroid hormones from working properly by taking their place on cellular receptors. This prevents your cells from getting the energy signals they need, which ultimately slows down your metabolism.

What the research says
2 studiesStudy: Clinical and laboratory aspects of 3,3′,5′-triiodothyronine (reverse T3)
The study confirms that reverse T3 acts like a dummy key that fits into thyroid hormone locks but does not turn them, which blocks the real active hormone from working and slows down the body's metabolism.
Study: The Influence of Reverse Triiodothyronine on Neuropsychiatric Disorders: A Narrative Review.
The study confirms that inactive rT3 acts like a fake key that jams thyroid hormone locks, preventing the real hormone from working and slowing down the body's cellular functions.
