*In general you want the bOHB to increase blood bOHB levels by about 10 to 12-fold (bringing bOHB levels form around .5mmol/L up to the 5 to 6 mmol/L range in the most responsive of your two groups. If your response is lower or higher, you will probably have to change your dose and retry. | *In general you want the bOHB to increase blood bOHB levels by about 10 to 12-fold (bringing bOHB levels form around .5mmol/L up to the 5 to 6 mmol/L range in the most responsive of your two groups.
