Nutritionist Advocates Natural Diet Before Collagen Supplement Use
A recent study has underscored the significant benefits of collagen, a key protein, for enhancing skin elasticity, bone strength, and muscle repair. However, experts are cautioning that while collagen supplements can be effective, they require long-term use to yield results, and natural dietary approaches should come first.
The Role of Collagen in the Body
Collagen is one of the most abundant proteins in the human body, essential for building muscle, cell repair, and maintaining skin hydration. As we age, natural collagen production declines, leading to potential aesthetic and functional issues such as wrinkles and joint discomfort. Vicky Pennington, a nutritionist at Boots, emphasised that collagen supports holistic skin maintenance, healthy bones and joints, muscle repair, and organ protection, including gut health.
Prioritising Natural Sources Over Supplements
Before turning to collagen supplements, Pennington urges individuals to focus on natural methods to sustain collagen levels. She recommends a balanced diet rich in nuts, seeds, colourful fruits and vegetables, fish, and grass-fed protein. Specifically, marine collagen from wild-caught fish like salmon is absorbed up to 1.5 times more efficiently than sources from cows or pigs, making it a superior choice when available.
Timing and Consistency in Collagen Intake
There is no perfect age to start taking collagen supplements, but many people begin in their 20s and 30s, as collagen production accelerates its decline after age 40. Pennington noted that collagen does not provide instant effects; consistent use over a long period is necessary to achieve the best outcomes. This aligns with growing popularity among younger generations, with surveys indicating that half of Gen Z and millennials have tried collagen, compared to just 20% of those in their 60s.
Variety and Accessibility of Collagen Products
Collagen supplements are available in multiple forms, including tablets, powders, capsules, gummies, and drinks, catering to diverse preferences. Kirstie Thorley-Mitchell, head of wellness at Boots, highlighted top picks such as Free Soul Collagen Gummies for £14.99, Absolute Collagen’s Liquid Marine Collagen sachets for £30, and Boots Marine Collagen tablets for £33. To assist consumers, Boots has introduced wellness training for over 500 Health & Wellness Specialists across 140 stores nationwide.
Sceptical Views from Medical Professionals
Despite the hype, some experts remain cautious. Professor Faisal Ali, a consultant dermatologist at Mid Cheshire NHS Trust, advised in 2025 that the most effective strategies for skin health include using sunblock, maintaining a healthy diet, and quitting smoking. He argued that these measures have a far greater impact on ageing skin than collagen supplements, emphasising a holistic approach to wellness.
