Q: Can DCA be taken while fasting ? Or is it better to wait until the fasting is done ? I‘m on a 30 day fast.MarekA: Dear Marek, thank you for your question. DCA can still be absorbed while you are fasting. However, if you take DCA in powder form, dissolve it into a solution, drinking it on an empty stomach may cause heartburn after a while. The stomach that has had no food for longer periods of time can get irritated really easily. To avoid this, you should take Sodium dichloroacetate in a capsule form. This way it will be lighter on your stomach. Also, take lower doses when you’re on your fasting protocol. Taking 6,25-12,5 mg/kg daily should be great.
