Well, I never thought of this. I’ve taken ketone salts before and measured my ketones using a blood tester. I didn’t find much improvement, but that might be because the blood tester only measures D isomers, not L isomers, and ketone salts have some/a lot of L isomers:
So, when I thought ketone salts didn’t do much, in terms of raising ketone levels. this is not true.
In this study, they compared the blood testers we can buy with a blood tester only available in labs. There was quite a difference.
