Safety and your surgical team

More in our complete guide to nutrition around surgery, or take our questions to ask your surgical team to your appointment.

Is it a medicine or a supplement?

Neither a medicine nor a meal replacement. SurgiFuel™ is a food supplement. It sits alongside the advice your surgical team gives you around an operation, rather than replacing it, and it isn't intended to prevent, treat or cure any condition.

Who is SurgiFuel™ for?

It is designed for adults having a surgical procedure, in the two weeks before or after. If you have a medical condition or dietary requirement, check with your surgical team before use.

Should I check with my surgical team first?

Yes. Timing depends on your own procedure and health, so always follow the advice your surgical team gives you. SurgiFuel™ sits alongside that advice and never replaces it.

Can SurgiFuel™ replace a varied diet?

No. SurgiFuel™ shakes are food supplements. They are not a substitute for a varied diet or for advice from your surgical team.
