In this issue of After Hours, Dr Vincent and Stephen explore a deceptively simple question: why are we not healthier despite having more supplements, health products, and wellness information than ever before? The discussion examines the gap between marketing and science, highlighting how cumulative nutrient exposure, poor supplement combinations, misleading "natural" claims, and a lack of focus on bioavailability may prevent people from achieving better health outcomes. The newsletter also answers subscriber questions about simplifying supplement routines, choosing effective products, understanding antioxidants, and avoiding the hidden risks of over-supplementation.
In this week’s After Hours podcast, Stephen and I tackled what I believe is one of the biggest contradictions in modern health: we have more supplements, health technology, and wellness advice available to us than ever before, yet many people still don’t feel healthier. We explored why regulation, transparency, and scientific evidence matter when making health decisions, and why consumers need to be cautious of bold promises and the endless stream of “breakthrough” products that appear almost daily. We also discussed the important role regulatory bodies such as the TGA play in maintaining standards and protecting public trust.
One of the key themes we explored was supplement overload. In my experience, more supplements rarely mean better outcomes. In fact, taking too many products can sometimes reduce effectiveness when nutrients compete for absorption or create unnecessary complexity. My philosophy has always been to focus on a small number of well-formulated, highly bioavailable products that your body can actually use. Stephen shared some practical examples of how common supplement combinations can interfere with one another and highlighted how AI tools may help people identify potential issues in their routines, while remembering that AI should never replace professional medical advice.
We also discussed what separates genuinely effective supplements from clever marketing. Not all antioxidants are created equal. Their source, structure, extraction method, and bioavailability all influence whether they can deliver meaningful benefits. I shared why I’ve spent much of my career studying how to preserve and activate apple phenolics so they remain usable by the body. We also spoke about the risks of assuming that “natural” automatically means safe. Supplements can be beneficial, but they can also be harmful when used excessively or combined inappropriately. Ultimately, the message of this episode is simple: focus on quality over quantity, understand what you’re putting into your body, and make evidence-based decisions rather than chasing the latest wellness trend.
With my best,
Dr Vincent
