Over 75% of the U.S. population is vitamin D deficient, which has led to a major increase in supplementation. Many people are unaware that a significant portion of the world's vitamin D3 is derived from a seemingly unconventional source: sheep's wool. This article explores the process, properties, and ethical considerations surrounding the vitamin that is made from sheep's wool.

While our bodies can produce vitamin D3 from sunlight, many supplements are manufactured from other sources. So, what are D3 vitamins made from? Traditionally, vitamin D3 is derived from animal products, most notably from the lanolin found in sheep's wool, but modern advances have also introduced effective plant-based alternatives.
