Holland & Barrett is a high-street health shop selling vitamins, supplements, sports nutrition, natural beauty and health foods, both online and in its stores. It suits anyone who buys supplements regularly, as well as shoppers looking for vegan or free-from food. Much of its own-brand range is on a multibuy deal at any one time, and you can shop by need, such as immunity, energy or joints, as well as by product type. Always check a product's label and speak to a pharmacist or GP if you're unsure whether a supplement is right for you.
