Bovine collagen: Sourced from cows; also found in bone broth and marrow.
Marine collagen: Derived from fish skin; often praised for its bioavailability.
Both can be effective, but marine collagen may be easier for the body to absorb, while bovine options are often more affordable.
Protecting Your Natural Collagen Levels
Beyond supplements, everyday habits play a major role in collagen health. According to the Cleveland Clinic, factors that accelerate collagen breakdown include:
Excessive sun exposure (UV damage)
Smoking
High sugar and refined carbohydrate intake
Signs your collagen may be declining include:
Wrinkled, sagging skin
Hollowing around the eyes and cheeks
Joint stiffness or pain
Weakened muscles
Digestive issues
Poor circulation
The Bottom Line
Collagen supplements aren’t inherently harmful—but quality matters. While they can help improve skin texture and joint health, choosing an unverified product could expose you to harmful toxins over time.
Dr. Ahmed’s advice?
“Don’t just buy the cheapest option online. Look for brands that are transparent, test for purity, and clearly state what’s in the product. When it comes to your health, it pays to be picky.”
So before you reach for that next scoop or capsule, ask yourself: Do I know exactly what’s in this bottle? Because when it comes to supplements, what you don’t know can hurt you.
