About this course

Antioxidants are vital biological molecules that defend us against the many oxidative pathways. We need to be aware however that the oxidants also have some useful functions. They are messenger molecules that are at least in part identifying areas of potential damage. If we are forcefully suppressing oxidants, we may be disrupting physiological balance. In fact, clinical studies have failed to find much benefit of antioxidants for any of our major degenerative diseases.

The role of antioxidants in preventing excess damage is valuable, but loading too much defence may be similarly problematic. Christine Houghton has prepared a presentation for us that reviews the clinical role of antioxidants and she will likely change the way that you prescribe them. We need to be a lot more careful about which, how much and when we prescribe antioxidants.
What you receive:
  • Clear protocol explanations from some of the world's top practitioners
  • Clinical pearls for improved practice results
  • Access to your audio and video recordings via the App Store
  • A downloadable PDF of the presenter’s slides
  • Links to all referenced research papers and useful clinical handouts
  • Access to the community hub where you can get answers to your questions
  • A 30-day money back guarantee

From this course you will

  • What we mean by the terms ‘free radical’ and ‘oxidative stress’
  • What do we expect an ‘antioxidant’ to do?
  • How the ‘Free Radical Theory of Ageing’ has impacted our thinking on antioxidants
  • If a cell is responding to a stressor by up-regulating its internal defence mechanisms, what happens if a large quantity of antioxidant is added to the cell?
  • Review the meta-analyses looking at antioxidant supplements in disease prevention that have failed to show protection against cancer, CVD and Type2 diabetes. Why?
  • Challenge the outdated concept that ‘free radicals are bad’ and ‘antioxidants are good’
  • How do we classify the various types of antioxidants that impact human health? Direct-acting antioxidants? Indirect-acting antioxidants?
  • Human cells up-regulate their defences as a response to a stressor. How does this work?
  • If a cell up-regulates its own defences by activating Nrf2, what is the most effective way to do this?
  • Address disease by accessing cellular upstream mechanisms vs working downstream with symptomatic therapies
  • What types of tests should a clinician order in order to determine the level of a patient’s redox balance?

    This presentation will challenge your current concepts of oxidants and antioxidants and will lead to better patient care. There will be plenty of opportunity for you to ask questions. You are welcome to send any questions for Christine to and we will put these to her doing the live webinar.
