Slightly tangential to Creatine kinase but A1cHero_PHX reminded me — does anyone have experience combining this with metformin?

I know it is not exactly on-topic but it seems related enough to ask here rather than starting a new thread. Apologies if this has been covered — I did search first.

Thanks for sharing this, A1cHero_PHX. A few questions about your Creatine kinase experience:

  1. What dose did you start at?
  2. How long before you noticed side effects improving?
  3. Did your provider have any specific recommendations about Creatine kinase?

I am in a similar boat and trying to learn from others' experiences before my next appointment.

OP here — wow, did not expect this much response! Thank you all for the thoughtful replies on Creatine kinase.

To answer RegAffairsDC: I started tracking everything in a spreadsheet from day 1.

Quick update: I will post a proper update thread soon. Thanks again for the evidence-based discussion — this is exactly why I posted in a science-based community. 🙏
