Ketone drink study reveals surprising effects on blood hormones
NCT ID NCT06053138
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study with 16 healthy adults tested how a ketone supplement affects beta-hydroxybutyrate (BHB) levels and erythropoietin (EPO), a hormone that controls red blood cell production. Participants took either the ketone drink or a placebo for two weeks. Researchers measured BHB from different blood sampling sites and checked EPO, estradiol, and ferritin levels. The goal was to understand ketosis effects on these markers, not to treat any disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ketone monoester dietary supplement
- What this could lead to
- If successful, this could help researchers understand how ketosis influences erythropoietin and hormone levels, potentially guiding future studies on metabolic health.
- What could go wrong
- This is a small, early-stage study with only 16 healthy participants, so results may not apply to broader populations or have direct clinical impact.
