* The level required to be ketogenic (hyperketonemia) has been suggested as 0.2 mmol/L measured as the combination of AcAc and BOHB in whole blood as this is slightly above the levels seen in "normal" individuals<ref name="Robinson-1980"/>.
* The book "The Art and Science of Low Carbohydrate Living" calls the range 0.5 to 5.0 mmol/L of blood ketones "nutritional ketosis"<ref name="Phinney-2011-p31"/>
* The follow on book "The Art and Science of Low Carbohydrate Performance" suggests that BOHB levels of 0.5 mmol/L to 3.0 mmol/L is "optimal"<ref name="Phinney-2012-p155"/>, with benefits starting at 0.5 mmol/L and improving to 3.0 mmol/L, but levels above 3.0 mmol/L not producing additional benefits<ref name="Phinney-2012-p157"/>.(It is unclear what research these levels are based on.)
* For epilepsy, the recommendation is for AcAc to be 80-160 mmol/L as measured by urine dipstick<ref name="Kossoff-2011-p201"/>, though this level is not necessarily sufficient<ref name="Gilbert-2000"/>.
* The range of 2 to 7 mmol/L<ref name="Vanitallie-2005"/> or 2 to 5 mmol/L<ref name="Veech-2001"/> has been suggested in some literature as a "therapeutic" range.
* A study of 74 children on the ketogenic diet for epilepsy found that blood BOHB levels of greater than 4 mmol/L were correlated with better seizure control than those with lower levels<ref name="Gilbert-2000"/>.
