What Is Vitamin C and Why Is It Important?
Vitamin C — also known as ascorbic acid — is one of the most essential vitamins our bodies need every day. Found naturally in fruits and vegetables like oranges, strawberries, and bell peppers, it plays a key role in supporting our immune system, keeping our skin healthy, and fighting off harmful free radicals.
If you’ve ever caught a cold and reached for a glass of orange juice, you’ve already experienced Vitamin C’s popular reputation as a cold-fighter. But that’s just one of its many benefits.
Here’s what Vitamin C helps do:
- Boosts your immune system: It helps white blood cells function better and protects them from damage.
- Supports healthy skin: Vitamin C promotes collagen production which helps with wound healing and keeps your skin firm and youthful.
- Acts as an antioxidant: It neutralizes free radicals that can damage cells and contribute to aging and diseases.
- Improves iron absorption: Especially helpful for people who don’t eat meat.
Though most people get enough Vitamin C through diet, getting a little extra through supplements can be beneficial — especially in today’s busy world, where nutrition sometimes takes a back seat.

When Is the Best Time to Take Vitamin C?
So, now that we know why Vitamin C is so important — when’s the best time to actually take it? Timing can make a difference in how well your body absorbs and uses it.
The basic rule? Take it in the morning or during the day, not at night.
Here’s why:
- Vitamin C is water-soluble: That means your body doesn’t store it for later. You need to keep replenishing your supply, and it works best when taken consistently and at the right time.
- It can be energizing: Some people find Vitamin C helps them feel more alert, so taking it in the evening — especially just before bed — might not be ideal.
- Better absorbed on an empty stomach: Try taking Vitamin C about 30 minutes before a meal or two hours after. However, if it makes your stomach feel uncomfortable, take it with food for gentler digestion.
Pro tip: If you’re taking a multivitamin or iron supplement, read the label. Many of them already include Vitamin C to enhance absorption. Doubling up unintentionally can sometimes cause mild side effects like an upset stomach.

How Much Vitamin C Should You Take?
Great question! The answer depends on your age, gender, lifestyle, and overall health. According to the National Institutes of Health, here’s the daily recommended amount:
- For adult women: 75 mg/day
- For adult men: 90 mg/day
- For pregnant women: 85 mg/day
- For smokers: Add 35 mg/day more, as smoking drains Vitamin C levels faster
Most over-the-counter supplements range from 250 mg to 1000 mg per serving — well above the basic requirement. But don’t worry, Vitamin C is generally safe, even in higher doses. The Tolerable Upper Intake Level (UL) is 2000 mg per day for adults. Taking more than that might cause:
- Nausea
- Diarrhea
- Stomach cramps
Tip: If you’re concerned about getting enough but want to avoid mega-doses, consider a “buffered” or time-release Vitamin C supplement.
Also, remember that consuming Vitamin C regularly over time matters more than taking a large dose once in a while. It’s kind of like watering a plant — it’s better to water it a little each day than dump a gallon on it all at once!

Simple Ways to Add More Vitamin C to Your Day
Not a fan of pills? No problem. Vitamin C is super easy to add to your diet naturally. Here are some tasty ways you can boost your intake:
- Start your morning with a glass of fresh orange juice or a fruit smoothie.
- Snack on kiwis, strawberries, or pineapple — they’re packed with Vitamin C.
- Add raw bell peppers or broccoli to your lunch salad.
- Try making a refreshing homemade lemonade — lemons are also a good source.
And if you’re always on the go, keeping a Vitamin C chewable tablet in your bag might be the backup you need.
Final Thoughts: It’s About Balance
Like most things in life, getting your Vitamin C right is about balance. Aim to take it:
- In the morning or daytime
- On an empty stomach if possible
- In moderate doses, unless otherwise advised by your doctor
Being consistent is more important than being perfect. And while Vitamin C won’t magically make you invincible, it’s a powerful little nutrient that supports your health in big ways.
So next time you’re planning your morning routine — whether it’s a cup of tea, a multivitamin, or that slice of toast — think about adding some citrus love to it!
