Collagen supplements have grown in popularity over the past few years, becoming a regular expense for millions of people. Supplement companies constantly market these powders and pills, promising everything from flawless skin to instant athletic recovery.
As a consumer, paying attention to these claims can be overwhelming. Before you allocate a portion of your monthly budget to these products, you need to separate the scientific reality from the aggressive marketing campaigns.
To find out what collagen can and can’t do, researchers at Anglia Ruskin University recently completed a comprehensive review of previous studies of these supplements.
They analyzed data from nearly 8,000 people from 113 clinical trials. Their findings, published in the Aesthetic Surgery journal Open Forum, paint a clearer picture of where the protein helps and where it fails.
The first major area where collagen shows its value is your skin. Data confirm that taking collagen leads to measurable improvements in both skin hydration and elasticity.
However, researchers note that these benefits are dependent on your dose and how long you take the supplement. You can’t just drink a few shakes and expect your appearance to change overnight. Consistent, long-term use is required to see these solid anti-aging results.
The second benefit is relief for individuals suffering from osteoarthritis. Joint wear and tear is a big issue as we age, and university researchers found that collagen provided a significant reduction in joint pain and daily stiffness.
Along with these pain-relieving benefits, the study highlighted modest increases in lean muscle mass and overall connective tissue strength.
one in Summary Regarding the findings, study co-author Lee Smith, professor of public health at Anglia Ruskin University, says:
“This study brings together the strongest evidence to date on collagen supplementation. Collagen is not a cure-all, but it has reliable benefits when used consistently over time, particularly for skin and osteoarthritis. Our findings show clear benefits in key areas of healthy ageing, as well as dispel some of the myths associated with its use.”
A scientific review debunked one of the most popular claims driving the sports supplement industry. If you’re buying collagen to speed up your recovery after heavy exercise, you’re wasting your money.
The research team found no significant improvements in muscle recovery, pain reduction or tendon mechanical properties after exercise.
Researchers also examined other bold marketing claims, looking for evidence that the supplement could improve blood pressure, cholesterol, blood sugar levels or oral health. They found that the data in these areas is inconclusive.
Researchers emphasize that collagen can be a sensible, low-risk addition to your daily routine, provided you understand what you’re paying for. If you focus on consistent use and ignore exaggerated fitness claims, you can get real value from your purchase. Be sure to consult your doctor before starting any new supplements — even over-the-counter products may interact with certain medications or be incompatible with certain medical conditions.
