fourfive Multi Mushroom Blend vs Holland & Barrett Immunity: What Does the Data Say?
These two products take very different approaches to immune support. The fourfive Multi Mushroom blend (£25.00, 80/100) delivers 10,000mg of five functional mushrooms — Lion's Mane, Reishi, Chaga, Shiitake, and Maitake — extracted from 100% fruiting bodies using dual extraction, with polysaccharide content above 40%. Holland & Barrett's Advanced Immunity (£6.75, 70/100) is a more conventional multi-nutrient formula pairing established immune vitamins with Shilajit, aimed at broad seasonal protection in a single affordable capsule.
If you're specifically chasing cognitive support alongside immune function, or managing stress and sleep, the fourfive blend is worth the premium. It's built around mushroom bioactives with a strong polysaccharide profile and excellent user feedback. But at £25 for 60 capsules, it's a commitment. Holland & Barrett's option scores 80/100 for value versus 80/100 for the fourfive on that same metric, but costs a fraction of the price — sensible if you just want basic seasonal cover without mushroom-specific benefits.
Neither product carries third-party testing certification, so neither has a purity advantage there. The Holland & Barrett formula is vegetarian-friendly and explicitly positioned for cold and flu prevention. The fourfive product doesn't specify allergen or dietary status in the available data, so check the label if that matters to you.
