Biogen (a Dischem brand) has been advertising Biogen Peptan Collagen extensively on Cape Talk, among other. This product is essentially hydrolyzed collagen.
Does taking collagen have any benefits?
Here is a good review published in Time magazine online, which gives the low down on this ‘supplement’.
“There are many preliminary trials showing potential benefits for everything from osteoarthritis to skin improvement,” Moyad says. Research has also linked collagen supplements to improved skin elasticity and skin moisture. But Moyad emphasizes that all of this research is preliminary. “The studies are weak in general,” he says—meaning small in scope, short in duration or not yet replicated by follow-up experiments.
Another recent review of the claims is dissected in an article in Business Insider: It’s supposed to help your skin, improve joint health, and assist with gastrointestinal distress.
“Verdict? The cheapest way to get the supposed benefits of collagen might be investing in a healthy diet.”
And from Vogue magazine:
Effects on Skin Grossman and Goldbach both say it’s hard to determine how much of the collagen you eat (or take via supplement) gets absorbed and then repurposed for various organs. Grossman says, “More studies need to be done to help to figure out how these products may or may not be affecting our bodies.”
This recent research study (January 2017) makes the explicit point examining collagen hydrolysates of fish (Peptan® F 5000, Peptan® F 2000) and porcine (Mobiforte®) origin, that “no CH modulated collagen biosynthesis in human knee cartilage explants” and “Further, due to the high variability in peptide composition between CH preparations, no effect can be extrapolated from a CH to another mixture“.
