When should you really be taking your collagen supplement? Here's what the experts say

I've learnt a great deal about life, love and lush-looking skincare routines from Korean dramas. Even my preliminary knowledge on when to take collagen came from these shows, where supplements often feature as a non-negotiable in K-Beauty regimens. Stirring it into my morning coffee has been a complete game-changer. Popular across ages for supporting skin protection, texture, firmness and hydration, collagen is generally recommended for those aged 25 and above. Added bonuses include stronger hair and nails. When it comes to timing, though, I've found that consistency matters far more than the exact hour you take it, especially when paired with a balanced diet and healthy lifestyle habits.

How do they work?

"Randomised, controlled trial studies and meta-analyses have been done on collagen supplements, and these have shown a significant improvement in a person's overall skin health. In most cases, this has been seen in less than eight weeks,” says Dr Deepthi Atmakuri, dermatologist and founder of Clinica Derm. While collagen particles don’t travel directly to the skin, they’re broken down during digestion into amino acids, the building blocks of protein. These amino acids are then absorbed into the bloodstream and can help stimulate the production of new collagen in the body. Dr Deepthi says you may notice improvements in 2-3 months, but immediate effects like plumper-looking skin and reduced dullness can present themselves as early as 15 days.

When to take collagen

There’s no rigid schedule for collagen  supplements, but regular intake is essential. “Consistency is key because your body needs a steady supply to experience long-term benefits,” says Dr Archana Batra, dietician and certified diabetes educator. She suggests a few easy ways to build it into your routine:

  1. On an empty stomach: Collagen is best absorbed in an acidic environment, so take it on an empty stomach in the morning. If you're intermittent fasting, take it right after the fasting period and allow some time before breakfast.
  2. Before bedtime: Taking collagen before bedtime can benefit the body as it repairs and regenerates during sleep, potentially making a bigger impact.
  3. Post-workout: Collagen's ability to help with muscle recovery and joint health has contributed to its popularity. Taking it after your daily workout can reduce muscle soreness by enhancing blood flow and nutrient delivery.

For those with sensitive stomachs, Dr Batra recommends taking collagen with meals. This won’t blunt its benefits; in fact, the body’s enzymatic activity peaks during digestion, aiding absorption. Pairing collagen with vitamin C can further enhance its effectiveness, as the nutrient plays a crucial role in collagen synthesis. Citrus fruits or vitamin C supplements work well here. That said, iron supplements may compete with collagen for absorption, so it’s best to space them out if you take both.

How to pick the right kind of collagen

Always label-check for 'hydrolysed' collagen, also known as collagen peptides. These are easier for the body to absorb and can be mixed into both hot and cold drinks. Dr Deepthi notes that marine collagen is widely preferred for all skin types, as its structure closely resembles human collagen. It suits oily, combination, dry, and sensitive skin, with added hydration benefits for dry skin. If you’re allergic to seafood, bovine collagen is a reliable alternative.

“As for plant-based collagen, there’s very limited research to support its efficacy,” she adds. Marine collagen can have a slightly unpleasant smell, which is why many brands add flavours like lemon or berry to make it more palatable.

The expert on 'super aging' breaks down the science — and grift — in anti-aging

 

It's a strange moment for growing old. Longevity is a cultural obsession: Biohackers plunge into ice baths, influencers push peptides, and tech elites pour ungodly sums into chasing immortality. Medical breakthroughs using AI promise to help us predict and prevent disease before it begins. But what actually helps us age well?

Cardiologist Eric Topol says the answer begins by rethinking what we're trying to optimize: not lifespan, or how long we live, but health span, the years free from major age-related diseases like heart disease, cancer or neurodegenerative illness.

"The average American health span is 64," Topol says, referring to when disease is likely to set in. "But lifespan is 79 on average. So you've got a big gap of about 15 years where your health span has ended and your lifespan continues."

Topol studies what determines one's health span and how we can change our experience of old age.

At Scripps Research Translational Institute, where Topol is the founder and director, he studied the DNA of people over 80 who hadn't contracted a major chronic disease. Topol called them "Super Agers" and compared their genomes with the average population to uncover what advantages could be found in their genes.

But Topol's team didn't find anything.

"The stunning result was while there were some small differences, otherwise there was not much to be able to say this was a genetic story at all," Topol says. There was no secret DNA to a better elderly life. Topol discovered that what mattered more was a web of factors: exercise, sleep, social connection, de-inflammation, immune system health and preventive medicine. His findings suggest healthy aging may be shaped less by fate than by choices and, increasingly, by better predictive tools.

He has become a champion for the ways that artificial intelligence will transform preventive medicine. From retinal scans that can flag risks for Parkinson's or heart disease, to models that may help predict Alzheimer's decades early, Topol sees AI shifting medicine from reacting to disease to getting ahead of it.

"In the years ahead, we will regard AI's most important contribution as facilitating prevention," he predicts.

But he is equally excited that the foundations of healthy aging are surprisingly low-tech. Exercise matters, with resistance and balance training. So does regular deep sleep. Staying socially engaged and spending time in nature both prove to be preventive factors.

Topol points to emerging evidence that even some vaccines can help support immune resilience; for instance, he says, "We've learned that the shingles vaccine reduces Alzheimer's and dementia by at least 20 to 25 percent," purely by the ways it protects the immune system.

So the most powerful longevity tools may not be glamorous quick fixes found in the links of an influencer's bio, which is why Topol is so skeptical of the tens of billions of dollars flooding the anti-aging industry.

Whether it's cold plunges, "protein maxxing" or experimental peptides, he sees a marketplace growing faster than evidence can keep up. Specious claims about unregulated products, he says, are "just completely out of control."

His advice is less seductive than a biohacker's blueprint, maybe, but more durable: Be wary of optimization fads. Stick to evidence-based opinions, "not eminence-based" opinions. Invest in habits, not miracles. Healthy aging isn't reserved for people with lucky DNA or elite resources. Even if one starts in midlife, evidence suggests lifestyle changes can add years of healthy living.

Getting older, Topol argues in his book Super Agers, doesn't have to mean passively waiting for decline or believing the fate of your ancestors portends your own. It is something you can shape — perhaps not immortality, but more vibrant, enjoyable years.
