Thorne’s premium Vitamin D supplement is a carefully formulated product designed to support crucial functions in the body. Vitamin D not only promotes healthy bones and muscles but also plays a role in cardiovascular health and immune function. While sunlight provides natural vitamin D, many individuals, particularly the elderly, face challenges in obtaining sufficient amounts from sunlight and their diet. In such cases, vitamin D supplementation becomes essential. Thorne Vitamin D supplement stands out from the rest as it avoids potentially detrimental ingredients like lactose, BHT, BHA, sodium benzoate, and sorbic acid, making it suitable for those with sensitivities. The recommended daily intake of 800 IU vitamin D in the US is based on the minimum required to prevent bone disease. However, research suggests that optimal health requires serum vitamin D levels within a specific range. Achieving this range varies from person to person, making individualised supplementation crucial.
