When you hear the word collagen, what comes to mind?
Many people only associate collagen with lip fillers and injectables to plump up your pout, or with the latest anti-aging serums that promise to boost skin elasticity.
But collagen is so much more than these superficial perks—and it’s time we start giving it a little more credit.
- Here’s Why Collagen Should Be On Your Radar
- 1. We stop producing both collagen and elastin
- 2. We damage collagen
- The Benefits of Collagen
- Skin health
- Bone/joint health
- Improved sleep

According to Medical News Today, “Collagen is the most abundant protein in the human body and is the substance that holds the body together.”
So on top of being the “glue” that literally keeps our organs, tissues, muscles, etc. in the right place, it’s also found in our bones, ligaments, tendons, and joints. It supports all of these moving parts inside of us so things don’t fall apart.
And when collagen is mixed with elastin, another protein found in connective tissue, it acts as a strengthener to give tissues firmness.
That’s why collagen does so much to give our skin its youthful-looking elasticity and strength.
Unfortunately, here’s the problem: we don’t have an endless supply of this collagen support army; as we get older, our collagen levels decline for a few reasons:

Sure, this is just a natural step in the aging process of life, however, factors such as our lifestyle habits, diet, and exposure to harmful ultraviolet rays can affect how much we lose as we get older.
Between the pollution floating around in our environment and logging too many hours of fun in the sun, we also damage the amount of collagen we currently have.
Unhealthy activities such as smoking and exposure to toxic chemicals have the power to destroy our collagen levels even further.
When you combine these harmful acts with decreasing levels that happen naturally, it’s a recipe for an unhealthy body both inside and out.
To combat this, we must limit our exposure to these harmful actions.
Now that you understand collagen’s importance, let’s learn about the seven health benefits you’re likely to see when you start adding more of it to your already healthy diet.
In a small, double-blind, placebo-controlled clinical trial, a group of women between the ages of 35–55 were randomly given an oral supplementation of 2.5 g, 5.0 g of collagen, or a placebo.
Over the course of 8 weeks, researchers measured changes in the women’s skin moisture, skin elasticity, and skin roughness.
By the time the study finished, researchers discovered:
- “A statistically significant improvement” in skin elasticity for the two groups of women who received the collagen supplementation as compared to the placebo group
- “A statistically significantly higher skin elasticity level was determined in elderly women”
- “A positive influence of [collagen] treatment could be observed” with reference to the skin moisture test
Another study had female participants between the ages of 33–45 treat wrinkles twice a day with an antioxidant and collagen building peptide serum in an effort to boost their collagen levels.
In this study, the results showed “statistically significant improvements over Baseline within minutes of initial application; these positive findings continued to improve through Months 1 and 3.”
Don’t get too excited, as the research is still very young, but it’s worth looking into.
In a 24-week randomized, placebo-controlled, double-blind study, 147 athletes were given either a liquid form of collagen hydrolysate or a placebo.
For those given the collagen, “statistically significant changes” were found in the athlete’s joints at rest, when walking, standing, and when carrying objects or lifting.
The researchers took the study a step further using a subgroup with achy knees, or knee arthralgia. They found that “the difference between the effect of collagen hydrolysate vs. placebo was more pronounced.”
The same ingredient (glycine) that gives us energy can also help us sleep better at night.
In this randomized single-blinded crossover trial, participants were given a flavored glycine or a placebo 30 minutes before bedtime.
Normally these individuals would log 7.3 hours of sleep. However, the study cut their average time in bed to just 5.5 hours for three consecutive evenings. This was to induce daytime fatigue and sleepiness.
While the results aren’t strong enough to draw a firm conclusion, the researchers found that taking glycine “at bedtime occasionally improves the impairments in subjective alertness and neurobehavioral functions induced by acute and modest sleep restriction.”
You can find collagen in some of the foods you may already be eating.
For example, chicken and pork skin, as well as a cup or bowl of bone broth, will naturally give you a collagen boost.
