GIVE YOURSELF A LITTLE PEP TALK

Collagen peptides now come in shake, powder and even caramel-creamer forms, promising new life to your skin and joints. But do they work?

01 THE CLAIM

As you age, your body loses its ability to produce collagen, a protein that provides structure to your bones and connective tissue (skin, cartilage, tendons). So, the reasoning goes that taking collagen peptide supps will improve the condition of your joints, skin, hair and nails.

02 WHAT’S TRUE

“There’s some evidence that collagen peptides might improve skin and hair health, as well as joint health,” says Brian St Pierre, a Men’s Health nutrition advisor. “But this evidence is currently far from definitive. It’s only suggestive at this point.”

03 WHAT’S BOGUS

Taking collagen peptides doesn’t restore lost natural collagen. You might supplement to boost joint health, but your body may distribute those peptides elsewhere, if it absorbs them at all.

04 WHAT’S ALSO BOGUS

Despite what some supplement-makers claim, collagen peptides won’t help you sleep better or weigh less. Glycine, found in collagen, may have sleep benefits, but there’s limited data that a supplement helps. As far as dropping pounds goes, collagen is not a weight-loss stimulant.

05 YOUR TAKEAWAY

Natural collagen is essential for joint, skin, hair and nail health, but science hasn’t shown the benefits extend to supplements in the form of peptides, says St Pierre. Bone broth, chicken skin, fish and egg whites are all collagen-rich – so you might be eating plenty already.

06 SHOULD YOU SUPPLEMENT?

In a word, no. Collagen peptides can cost as much as £80. Though the research behind their benefits may seem promising, you’re better off investing in a healthy diet that’s naturally rich in collagen. Plus, research suggests that for some people, taking collagen peptides can result in nausea and excessive gas. Fun!
