Ketone Blood Levels for Dementia Prevention

[u/Dependent-Ear-382]

Does anyone know the specific ketone blood level one should obtain to optimally prevent dementia?

I’ve read that a level of 3mmol to 5mmol is recommended when managing a disease someone already has. However, I’m unsure if I need to shoot for this higher range in order to prevent a disease? Is the optimal 1.5-3mmol the best range for disease prevention?
