When you walk down the aisles of your local supermarket, there seems to be a new ingredient in town that people just can’t get enough of. First gaining popularity in supplemental powders, collagen is now popping up in products from beverages to bars to baked goods and everything in-between. According to SKIN LLC, in the 365 days leading up to February 25, 2018, the number of products featuring collagen in the grocery category catapulted by 430%! Americans seem to be convinced that they better load up on collagen-containing products. And with claims to help improve the appearance of your skin and support bone, joint, and muscle health, as well as promote weight loss, can you really blame us?
But, what is the deal with collagen? Is it worth your money? And are the claims in fact valid? Read on to get the lowdown.
Collagen is a protein that makes up 30% of the whole-body protein content and is ubiquitous in our bodies as it’s the main structural component of connective tissues including skin, tendons, bones, and ligaments.
Collagen itself cannot be absorbed as a fully intact molecule, so our body uses collagen peptides (also called collagen hydrolysates) – the popular form of collagen supplements on the market – as the building blocks for making collagen. Alternatively, our body can also build collagen from amino acids, which are found in a variety of animal and plant foods from eggs to quinoa to beans.
Vitamin C, the powerful antioxidant found in a variety of fruits and veggies, plays a role in collagen formation. Similarly, turmeric, or more specifically, the spice’s prized compound, curcumin, has also been shown to increase collagen synthesis and cell growth.
Most skeptics of collagen supplements or the collagen trend, in general, will point out that the majority of research on collagen has been funded by the collagen supplement companies, which opens the opportunity for potential bias. But, if the research is well done, the proof is still in the pudding.
While you can find additional research linking collagen to potential heart health benefits, gut health, as well as hair and nail health, and even sleep quality, the evidence to date is minimal.
At the end of the day, it takes a lot of convincing to make me believe that supplements are superior to eating a well-balanced diet, especially since some of them can easily be $50 bucks a pop. I’d rather see people opt to spend their money on a basket full of produce – which is really the cornerstone of a healthy diet – and opt for real, natural sources of protein that provide the essential building blocks for making collagen in the first place. But, if you’re curious to try collagen supplements or products, or have noticed personal improvements in the appearance of your skin or reduced pain in your joints, all the more power to you. It’s important to recognize the foods, habits, and supplements that work best for you and help you feel your best since we don’t all fit into the same mold.
