Holland & Barrett (H&B) Vitamin D3 1000 I.U.

Holland & Barrett is a staple of the British high street, recognized as one of the world's leading health and wellness retailers. This specific Vitamin D3 supplement is part of their own-brand range, which is widely celebrated for making nutritional health accessible. The product is primarily manufactured within the United Kingdom to meet stringent local quality standards.

Originally founded in 1870 by William Holland and Alfred Barrett in Bishop's Stortford, England, the brand has evolved from a small grocery store into a global retail powerhouse. Today, Holland & Barrett is owned by LetterOne, an international investment business headquartered in Luxembourg, which acquired the company in 2017 to expand its digital and international footprint. While ownership is international, the brand maintains its British identity and headquarters in Nuneaton, Warwickshire.
