Peptides for anti-ageing and recovery: benefits, risks and what experts say

Peptides are rapidly gaining traction in the health, beauty and fitness industries, with many people using them in hopes of slowing ageing, improving recovery and boosting overall wellness.

During a Health and Wellness discussion on 702, biomedical scientist Dr Judey Pretorius explained that peptides are short chains of amino acids — the building blocks of proteins — which play a key role in how the body repairs tissue, maintains skin structure and regulates biological processes.

She said the body naturally produces proteins needed for skin, muscles, hormones and healing, but this process becomes less efficient with age.

“The human body is like a factory producing amino acids all the time,” Pretorius explained.

“When these amino acids bind together, they form peptide chains, and those chains are responsible for important functions like collagen and elastin in the skin.”

As these structures decline over time, signs of ageing such as sagging skin and loss of elasticity become more visible.

Why are people using peptides?

Peptides are now commonly marketed for multiple uses, including anti-ageing, muscle recovery, hair and skin health, and general performance support.

Pretorius said interest is largely driven by longevity and appearance.

“People live longer today and want to age gracefully,” she said. “Peptides are one of the ingredients that can really make a huge difference.”

They are available in several forms, including oral supplements such as collagen drinks, topical skincare products and injectable treatments.

While aesthetic benefits are a major driver of demand, some users also report improved recovery and reduced soreness after exercise.

Safety concerns and regulatory warnings

Despite growing enthusiasm, experts warn that consumers should be cautious.

One of the biggest risks is the lack of regulation in parts of the supplement and cosmetic industry, Pretorius said.

“The barrier to entering the cosmetic industry is very low,” she explained. “Consumers must do homework to see whether claims are backed by clinical proof and whether companies operate in regulated environments.”

She advised buyers to check for certifications, regulatory approval and quality assurance before using peptide-based products.

Side effects and long-term risks

Pretorius noted that risks vary depending on the type of peptide.

Prescription peptide drugs used for weight loss — such as GLP-1-based treatments — have documented side effects including nausea, headaches and more serious complications.

However, she said over-the-counter cosmetic peptides generally have fewer severe risks when sourced from reputable manufacturers.

Still, medical professionals often advise consulting a doctor before starting supplements, especially for people with existing health conditions.

Not a miracle solution

Peptides alone are unlikely to transform appearance or health without other lifestyle factors.

Regular exercise, skincare treatments, nutrition and access to professional therapies often play a major role in results.

Experts agree that peptides may offer benefits, but they work best as part of a broader health strategy rather than as a stand-alone solution.
