Where do you get ketone salts?
Several brands of Ketone salts are all over the interwebs.
Check Amazon for possibilities. I have tried different brands and flavors, my personal favorites are KetoCaNa Lemon, InstaKetones orange and Kegenixs Prime pomegranate.
You can also use MCT oil which breaks down to ketones.
They can be pretty expensive but I found that I only need smaller amounts than recommended.
Just a spoonful in water or tea takes the edge off of hunger, gives me some energy and reduces brain fog.
