Woman loses 9kg in 28 days with collagen shake challenge

A 55-year-old woman from New Zealand has lost 9kg after completing The Collagen Co’s 28-Day Shake & Glow Challenge. The programme, which replaces one or two daily meals with Glow Shakes, has attracted over 35,000 participants since its launch. Many have reported improvements in energy, sleep, and appearance after finishing the challenge. The challenge centres on simplifying routines while supporting weight loss. Participants swap one or two meals each day for The Collagen Co’s Glow Shakes, available in flavours like Watermelon, Purple Grape, Mixed Berry, Passionfruit Mango, Strawberry, and Unflavoured. The structured approach helped the New Zealand woman stay committed throughout the 28 days.

After completing the programme, she noticed clearer skin, stronger nails, and healthier hair. Her energy levels rose, and her sleep improved. The shakes themselves have earned strong reviews, with many shoppers awarding them five-star ratings. The next 28-Day Shake & Glow Challenge begins on 18 May 2026. The company continues to promote the programme as a straightforward way to reset habits and achieve health goals.

The woman’s results included a 9kg weight loss alongside better sleep, increased energy, and visible improvements in her skin and hair. The challenge’s structured meal replacement system has drawn thousands of participants, with the next round set to start in May 2026.
