- Immune Support: Driven by post-pandemic health awareness, with vitamin D, zinc, and elderberry supplements leading growth.
- Gut Health: Probiotics and prebiotics are among the fastest-growing segments, with a projected CAGR of 7.1% through 2030.
- Plant-Based & Vegan Supplements: Aligning with the UK’s rising vegan population, plant-based protein powders and multivitamins are gaining traction.
