Do you have a morning routine of a cup of coffee before you start your day? Yes, you are like 64% of Americans according to a survey by Reuters. But have you thought about adding collagen to your coffee?
Some people have been adding collagen peptides to their daily coffee. First of all this add-on supplement is colourless and odourless so it won’t affect the taste of your coffee. But are the effects of this collagen supplement? Collagen is the natural component found in parts of our body like our skin, hair, nails, joints and bones. Some advocate that taking collagen supplement can help with your skin and joints. The ultimate hope is to rejuvenate your skin back to how it’s used to be when you are a teen and adding a bit more resilience to your joints so you can continue on all your active lifestyle.
Is there any scientific evidence that proves taking in collagen would improve your skin or joints? There is a double-blind placebo controlled study with women aged 45-65 comparing collagen hydrolysate (2.5 gm or 5 gm) versus placebo (no collagen at all) on skin wrinkle formation and other skin specific parameters. After 4 weeks and 8 weeks of taking this collagen peptide, they showed a reduction in skin wrinkle volume over the eyes compared with the placebo group. (Skin Pharmacol Physiol. 2014;27(3):113-9.)
Another study investigated whether taking active collagen peptides can improve skin moisture and elasticity. Collagen hydrolysate with a higher content of bioactive collagen peptides (H‐CP) showed statistically significant improved skin moisture and elasticity compared with placebo. (J Sci Food Agric. 2016 Sep;96(12):4077-81.)
In short, there may be some small studies showing that collagen peptides may be useful for your skin, but larger clinical trials are required to draw a concrete conclusion. But the good point is there are no relevant adverse effects observed in all the trials, so you may just go on and add some collagen to your usual cup of coffee.
