Actress and wellness influencer Davinia Taylor has engaged in a public dispute with medical professionals who challenge the efficacy claims made by her supplement brand, WillPowders. The conflict began when Taylor, who has 1.3 million followers on Instagram, criticized doctors she accused of "gaslighting" women regarding the benefits of collagen.
In response, several doctors took to social media to push back against Taylor's assertions. Dr. Lynette Ewart, a GP and personal trainer, stated, "If wanting some proof about what you’re being asked to spend your money on makes you a gobs**te, then I’ll happily wear that crown." Dr. Mike Banna, another NHS doctor, echoed this sentiment, emphasizing the importance of scientific evidence when promoting products to a vulnerable public. Both doctors have affirmed they do not accept payment to promote pharmaceutical or food products.
Taylor, formerly of the television show Hollyoaks and associated with the 1990s "Primrose Hill set," has reinvented herself as a wellness advocate. She co-founded WillPowders, a company selling supplements such as collagen powder, marketed with claims of improving skin, joints, and even calming the nervous system. Taylor asserts that her personal social media posts are separate from the company's official claims and are based on her own experiences.
The Science of Collagen and Other Supplements
The global market for collagen supplements is substantial, with sales projected to double by 2032. WillPowders offers Bovine Collagen Peptides Powder for £23, with marketing slogans promising to "change your ageing game" and alleviate aches and pains. Taylor has cited a study suggesting long-term collagen use may improve skin elasticity and hydration, and reduce osteoarthritis symptoms.
However, medical professionals point to limitations in the research. Dr. Ewart notes that many studies are short-term, involve small participant numbers, and are often funded by the supplement industry itself. A review in The American Journal Of Medicine concluded there was "no clinical evidence to support the use of collagen supplements to prevent or treat skin ageing" when lower-quality and industry-funded studies were excluded.
Experts explain that the body processes proteins, whether from food or supplements, by breaking them down into amino acids. While manufacturers suggest supplemental collagen fragments can signal the body to produce more collagen, the clinical significance of this effect in humans is debated. Taylor's claim that collagen can calm the nervous system, potentially linked to its glycine content, lacks clinical evidence for supplemental intake.
Beyond collagen, Taylor's brand promotes other supplements. Claims that MCT oil acts as a natural alternative to Ozempic for satiety, or that ketones provide rapid energy, are met with skepticism from doctors, who state there is no robust evidence for these effects comparable to prescription drugs or significant performance enhancement in healthy adults. Shilajit is marketed to "supercharge resilience" and aid hair growth, but evidence for these broader claims is weak. Electrolyte supplements are promoted for brain fog, though doctors suggest hydration is the primary factor, and there's little evidence for enhanced brain function beyond correcting dehydration. Nootropic supplements, like WillPowders' Brain Powder, are claimed to "unlock laser focus," with some evidence suggesting short-term attention enhancement when combined with caffeine, but limited proof for broader cognitive benefits.
Taylor's Response and the Broader Context
Davinia Taylor responded in writing, clarifying that her personal social media activity is distinct from WillPowders' corporate messaging. She stressed that she does not engage in paid brand endorsements or receive commissions on her personal platform, stating she only promotes products she genuinely believes in. She acknowledged that while some wording on the WillPowders website reflects customer experiences, the company's compliance team would review claims if they were found to exceed current evidence.
Taylor further explained her stance on medical professionals, stating her criticism is directed at a few individuals whose public debate style she finds performative, rather than the medical profession as a whole. She also suggested that the commercial interests of some doctors commenting on her activities should be considered.
She highlighted that WillPowders products have thousands of positive customer reviews, particularly for collagen's perceived benefits for hair, skin, and joints. Taylor also noted that the food industry in the UK is highly regulated and that neither she nor WillPowders are subject to any regulatory action.
Taylor attributed her interest in wellness to her own health journey, particularly navigating perimenopause and experiencing symptoms that she felt were dismissed by conventional medicine. She believes her message resonates with many women who feel unheard by the NHS and have found genuine help through her products.
