All About Dr Brad Stanfield and His Views on Health and Longevity

Dr. Brad Stanfield has made a name for himself as a general practitioner and health educator, particularly in the realm of supplements and longevity science. 

Dr Stanfield credentials include an MBChB and a fellowship from The Royal New Zealand College of General Practitioners, and he has built a platform on YouTube where he scrutinises health trends, nutritional supplements and scientific studies. 

While his content is often presented in a straightforward and digestible manner, a deeper look reveals both commendable qualities and concerning tendencies.

The Good: Rational Scepticism and Consumer Awareness

One of the most valuable aspects of Dr. Stanfield’s content is his emphasis on evidence-based medicine. He encourages his audience to critically evaluate what they put into their bodies and not to fall for marketing gimmicks. In a supplement industry that often prioritises profit over health, his scepticism serves as a useful counterbalance. Many companies cherry-pick studies to sell their products and Stanfield is right to call attention to this.

As for Dr Stanfield supplements, his Microvitamin supplement is an interesting development, as it consolidates multiple commonly taken vitamins — including Hyaluronic Acid and TMG — into a single product, potentially saving consumers money. His formulation choices reflect a practical approach to supplementation, rather than an excessive, kitchen-sink philosophy.

He also acknowledges the nuance in scientific research, often pointing out that the interpretation of studies can vary widely. His caution against mass dosing of supplements is also a responsible stance, as excessive intake of certain vitamins, such as B12, has been linked to potential health risks, including elevated cancer risks. While he is not outright dismissing supplementation, he emphasises the importance of moderation.

The Bad: Contradictions, Clickbait and Cherry-Picked Studies

Despite his commitment to scepticism, Dr. Stanfield sometimes falls into the same traps he warns against. His criticism of other figures in the longevity space — most notably Dr. David Sinclair — often seems more personal than scientific. While healthy debate is necessary, attacking individuals rather than ideas undermines his credibility. If one disagrees with Sinclair’s stance on resveratrol, for example, the most productive way to counter it would be through peer-reviewed research, rather than polarising YouTube content.

His videos have also gradually shifted from pure educational content to more attention-grabbing, clickbait-style thumbnails and titles. His early work was focused on delivering value, but recent content leans more towards controversy-driven narratives, which may be fuelling his declining viewership. 

He has also been known to contradict his past statements without properly addressing or correcting them, which can be confusing for his audience. When new research emerges that contradicts his previous claims, he acknowledges it but doesn’t always reconcile it with his earlier views, leaving inconsistencies in his content.

The Questionable: Overgeneralisation and Subjectivity

While Dr. Stanfield often calls for scepticism, he sometimes dismisses supplements too quickly. His stance on resveratrol, for example, is overly negative — while the evidence for lifespan extension in humans is weak, many individuals report cognitive benefits. He also expresses strong opinions on fasting, despite the wealth of positive anecdotal and scientific evidence supporting it. Just because he hasn’t found value in it doesn’t mean it’s ineffective for others.

Similarly, his take on chemical sunscreens leans toward fear-mongering rather than a balanced discussion. While it’s fair to highlight concerns, outright dismissal without presenting all sides can mislead viewers. The same applies to his views on certain vitamins, like vitamin C, where his analysis has been criticised for lacking nuance and cherry-picking data.

The Bottom Line: A Mixed Bag

Dr. Brad Stanfield is undoubtedly a smart and well-intentioned doctor who encourages critical thinking about health and longevity. His focus on recent studies and scepticism toward poorly supported supplement claims is refreshing in an industry flooded with pseudoscience. His growing inclination towards sensationalism, personal attacks and selective interpretation of research, however, undermines his credibility.

Science is ever-evolving and true objectivity requires presenting all relevant data, even when it contradicts personal beliefs. While Dr. Stanfield brings valuable insights to the table, his audience would be wise to apply the same level of scepticism to his content that he encourages them to use when evaluating others. After all, in the world of health science, no single person has all the right answers.
