Erythritol is a safe, keto-friendly sugar alcohol to try. It won’t spike your blood sugar anywhere near as much as sugar, but it does come with some minor side effects.


  • Has zero metabolic carbs
  • Doesn’t cause plaque build up on your teeth
  • Tastes pretty good in comparison to sugar


  • is not soluble in fat, you will need to powder it for cooking

Side effects

  • Is not metabolised by your gut so can have a mild laxative effect.
  • Has a slight cooling mouthfeel

The laxative effect

This is actually a beautiful thing. A low carb diet can often leave the practicer with mild to heavy constipation, this is where Erythritol shines, because it acts as a laxative if you supplement your heavy fat/protein main course with an Erythritol based dessert or sweetener it can help mitigate this effect.
