Exogenous Ketones & Therapeutic Ketosis
Dom D'Agostino's evidence-led take on exogenous ketones: what the esters, salts and MCTs actually do, how to use them sensibly, and his own blunt warning that higher is not better.
Dom D'Agostino is one of the leading researchers on ketones. Exogenous ketones (ketone esters, ketone salts, and to a lesser degree MCT/C8 oil) let you raise blood ketones without a strict ketogenic diet. They can acutely lower blood glucose and may offer modest cognitive or exercise effects, and there is genuine research interest in therapeutic ketosis for epilepsy and other conditions. But D'Agostino is emphatic on two points: ketones do not directly cause weight loss, and higher is not better, large ester doses can cause GI distress and, in principle, dangerous drops in pH. This is a sophisticated, optional tool, not a daily essential.
Why it works▼
Understand esters vs salts vs MCT
Each form behaves differently; matching form to purpose avoids waste and side effects.
Use them for a defined purpose
They are a targeted tool, not a general daily supplement.
Use modest doses and build slowly
His own lab work shows the dose is what separates benefit from harm.
Stack with MCT or caffeine if useful
Sensible pairings improve tolerability and effect.
Separate ketones from weight loss
A common misconception D'Agostino corrects directly.
- People already exploring ketogenic approaches
- Those curious about ketones for focus or exercise
- Anyone who wants the evidence, not the hype
- Self-experimenters who track carefully
- Higher is not better: large ketone-ester doses can cause GI distress and, in principle, dangerous drops in blood pH; start low and go slow
- Ketones do not cause weight loss on their own and they add calories; do not use them as a diet product
- Therapeutic uses (epilepsy, neuroprotection, cancer-adjacent research) are research-stage and must be pursued under medical supervision, not self-treated
- People with type 1 diabetes, on SGLT2-inhibitor medications, pregnant, or with kidney issues should not use exogenous ketones without medical advice (ketoacidosis and mineral-load risks)
