An estimated 1 billion people worldwide have inadequate vitamin D levels, a condition with far-reaching health implications. But what else is vitamin D called, and why does this single nutrient have so many different names? This guide will demystify the terminology.

Over 40% of Americans are deficient in vitamin D, often called the 'sunshine vitamin'. Many mistakenly search for specific dietary sources of 'vitamin D1,' unaware that this term is no longer used in modern nutritional science. Instead, the vitamin D family is primarily comprised of D2 and D3, both of which are crucial for human health.

The National Institutes of Health notes that symptoms of vitamin D toxicity are most likely to appear when a person's daily intake is at least 10,000 IU (250 mcg). To clarify, this article will answer the common question: how many mcg is 10000 vitamin D and provide crucial context for understanding dosages.

The ability to correctly identify which one of the following statements concerning vitamin D is correct relies on understanding its unique metabolic pathway and biological role in the body.
