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.
Understand esters vs salts vs MCT Esters: strong, fast, expensive, bad taste. Salts: gentler, mineral load. MCT/C8 oil: mild ketone bump, food-like
Each form behaves differently; matching form to purpose avoids waste and side effects.
Use them for a defined purpose Transient ketosis without dieting, blunting an oral glucose spike, or a possible focus/exercise aid; effects are modest
They are a targeted tool, not a general daily supplement.
Use modest doses and build slowly Begin with a small dose; D'Agostino warns large ester doses can cause GI distress and, in principle, risky acidosis
His own lab work shows the dose is what separates benefit from harm.
Stack with MCT or caffeine if useful MCT can extend ketosis; caffeine pairs for alertness; take with that goal in mind
Sensible pairings improve tolerability and effect.
Separate ketones from weight loss Do not use ketones as a weight-loss product; they do not burn fat by themselves and add calories
A common misconception D'Agostino corrects directly.
Ketones (chiefly beta-hydroxybutyrate) are an alternative brain and muscle fuel; supplementing them shifts metabolism toward ketone use transiently.

Is this for you
- 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
Cautions
- 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)
- These supplements are expensive
- Educational only, not medical advice
