The term "vitamin B8" is no longer used because the substance previously referred to as vitamin B8, inositol, is not considered a true vitamin. Here's why:
What Happened to Vitamin B8?
The key reason why inositol is not a vitamin is that our bodies can synthesize it naturally. True vitamins are essential nutrients that the body cannot produce on its own and must obtain from external sources like food. Inositol, however, can be made within our cells, although it's also available in some foods.
| Feature | Vitamin | Inositol (Previously Vitamin B8) |
|---|---|---|
| Definition | Essential nutrient body can't produce | Compound body can produce |
| Requirement | Must be obtained from external sources | Can be obtained from external sources or produced internally |
| Status | Essential nutrient | No longer considered a vitamin |
Inositol's Role
- Fat Processing: Inositol plays a role in how our liver processes fats.
- Muscle and Nerve Function: It supports optimal functioning of muscles and nerves.
Sources of Inositol
While our bodies can produce it, inositol is also found in various foods:
- Whole grains
- Nuts
- Legumes
Why the Change?
The reclassification of inositol from a vitamin to a vitamin-like substance acknowledges that the body has the capability to produce it in sufficient amounts to meet its needs. Therefore, the term "vitamin B8" has been phased out.
