Holland & Barrett Vitamin D3 400 I.U.

Holland & Barrett is one of the world's leading health and wellness retailers and the largest in Europe. The brand specializes in providing a wide range of vitamins, minerals, health supplements, specialist foods, and natural beauty products.

Originally founded in Bishop's Stortford, England, in 1870 by William Holland and Alfred Barrett, the company evolved from a small grocer into a global wellness powerhouse. While the brand has seen several owners throughout its long history, most of its branded supplement line is manufactured within the United Kingdom to maintain strict quality and regulatory standards.

In 2017, the company was acquired by L1 Retail, an investment arm of the LetterOne Group. Under this ownership, the brand has expanded significantly, focusing on digital integration and personalized health solutions while maintaining its strong presence in the UK and European high streets.
