Vitamins come in two main types:

Fat-soluble vitamins: These are stored in your body’s fatty tissues. They include:

How Vitamins Work in Your Body

Vitamins are like little workers in your body. Each one has a special job:

Your body is like a busy factory, and vitamins are the workers that keep everything running smoothly. Without them, many important jobs wouldn’t get done!

Skin’s Natural Defender

Vitamin E is often called the “beauty vitamin” because of its role in skin health:

• Protects skin cells from UV light damage
• Helps in the formation of collagen, keeping skin elastic

1. Can I get all the vitamins I need from food alone?

Yes, in most cases. A balanced diet with a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats can provide all the vitamins you need. However, some people may need supplements due to age, health conditions, or dietary restrictions. Always consult with a healthcare provider before starting any supplement regimen.

2. Are natural vitamins better than synthetic ones?

Not necessarily. Your body can use both natural and synthetic vitamins. The key difference is that natural vitamins from food often come with other beneficial nutrients. However, synthetic vitamins in supplements can be helpful when you can’t get enough from your diet alone.

4. Do vitamins expire?

Yes, vitamins can expire. Over time, they may lose potency. Always check the expiration date on supplement bottles and store them as directed (usually in a cool, dry place). For vitamins in food, proper storage and consumption before spoilage is key.

5. How do I know if I have a vitamin deficiency?

Vitamin deficiencies can cause various symptoms, including:

• Fatigue
• Weak immune system (frequent illnesses)
• Hair loss
• Dry skin
• Brittle nails

However, these symptoms can also indicate other health issues. If you suspect a deficiency, it’s best to consult with a healthcare provider. They may recommend blood tests to check your vitamin levels.
