Why is Vitamin F?
"Vitamin F" isn't a vitamin in the traditional sense; it's a term for two essential fatty acids: alpha-linolenic acid (ALA) and linoleic acid (LA). These aren't vitamins like vitamin A or C, but they are essential nutrients our bodies need but cannot produce on their own. We must obtain them through our diet.
- Alpha-linolenic acid (ALA): An omega-3 fatty acid crucial for various bodily functions, including brain and heart health.
- Linoleic acid (LA): An omega-6 fatty acid, also essential for numerous physiological processes. Both ALA and LA contribute to cell structure, growth, and development, influencing blood pressure and overall health.
Why the Misnomer "Vitamin F"?
The term "Vitamin F" likely arose from the fact that these fatty acids are vital for health, similar to the traditional vitamins. However, they are fats, not vitamins in the chemical classification sense. Traditional vitamins, like vitamin B12, are named according to their discovery order and chemical properties.
