What Are Vitamin Deficiencies?
Vitamin deficiencies occur when your body lacks essential vitamins needed for various bodily functions. These deficiencies can affect your overall health, skin, energy levels, immune system, and even mental well-being. They often result from poor dietary choices, certain medical conditions, or lifestyle factors.
In the USA, fast food and processed diets have made nutrient deficiencies surprisingly common, despite the availability of food options. Recognizing and addressing these deficiencies is key to maintaining a healthy life.
The Importance of Vitamins for Your Body
Vitamins are organic compounds crucial for growth, immunity, and energy. Your body needs them in small amounts but can’t produce most of them, meaning they must come from your diet or supplements.
Here’s why they’re essential:
- Boosting Immunity: Vitamins like C and D help protect you from illnesses.
- Supporting Growth: Vitamins A and K are vital for cell growth and bone health.
- Improving Energy Levels: B vitamins convert food into energy.
