Vitamin C: What It Actually Does for Your Body

Everyone knows what vitamin C is for, right? It’s that flu-busting vitamin that makes you reach for the orange juice when you feel the sniffles coming on. But it actually does way more than that!

Vitamin C has been widely recognized for so long that it’s easy to think we already know everything there is to know about it. It’s the vitamin we reach for when winter arrives, add to our shopping list when we’re trying to eat more fruit and vegetables, and occasionally remember when we spot it on the back of a supplement bottle.

But there’s quite a bit more going on.

Vitamin C is involved in a number of everyday processes in the body, from making collagen and helping us absorb iron to protecting our cells from oxidative stress. It also contributes to normal immune function, although that’s only one part of the picture.

So what else is this vitamin actually doing for you?

Your Skin Needs It Too

Collagen tends to get most of the attention when we talk about skincare, but it’s not just something found in your favourite serum. Your body makes collagen naturally, and vitamin C plays an important role in that process.

Vitamin C contributes to normal collagen formation, which is needed for the normal function of skin, bones, cartilage, gums and blood vessels. It also contributes to normal wound healing.

We’re not saying a vitamin C supplement is going to knock ten years off you, if only it were that simple! Skin health is influenced by plenty of things, including genetics, sun exposure, sleep, diet and the products you use. What vitamin C does provide is one of the nutrients your body needs to make collagen normally, making it a worthwhile part of looking after your health and skin from the inside out.

It Helps You Get More From the Food You Eat

Here is one of the lesser-known jobs of vitamin C. It can help your body absorb non-haem iron, which is the form of iron found in plant foods such as lentils, beans, chickpeas and leafy green vegetables.

That means your morning berries, a few slices of kiwi or some peppers alongside a meal can do more than simply make your plate more colourful. It’s also a nice reminder that nutrition isn’t always about individual foods being labeled as “good” or “bad”. Sometimes it is about how different foods work together.

Yes, It Supports Your Immune System

This is the one most of us know about. Vitamin C contributes to the normal function of the immune system, which is one reason it has become so closely associated with cold and flu season.

There is a bit of nuance here, though. Regular supplementation doesn’t generally stop healthy people from catching a cold, although research suggests it may slightly reduce how long a cold lasts and how severe the symptoms are for some people.

So rather than thinking of vitamin C as something to take only when you feel a sniffle coming on, it makes more sense to think about getting enough of it as part of your normal diet and routine.

It Helps Protect Your Cells

Another reason vitamin C matters is its antioxidant activity. Think of antioxidants as part of your body’s everyday defence system. Your cells naturally produce free radicals as they carry out normal jobs, such as turning food into energy, and that’s completely normal. However, too many free radicals can put extra stress on your cells.

Vitamin C is one of the antioxidants that helps protect your cells from oxidative stress. It’s one of the quieter ways vitamin C supports your health, but it is also why you will often see it mentioned when we talk about skin, healthy aging and overall wellbeing.

It’s Involved in How Your Body Uses Energy

Vitamin C also has a role in helping your body release energy from the food you eat. It’s not going to give you the instant lift you get from your morning coffee, but it does support the normal processes your body uses to turn the food you eat into energy.

It’s a small part of a much bigger picture when it comes to how you feel day to day. Your energy depends on everything from sleep and food to movement and stress, but getting enough of the nutrients your body needs gives those everyday processes the support they need to work properly.

Are You Getting Enough?

Getting enough vitamin C from food can be relatively easy, but that doesn’t necessarily mean it happens every day. Citrus fruits are the obvious example, but they’re far from the only option. Kiwi, strawberries, peppers, broccoli, tomatoes and potatoes can all contribute vitamin C to your diet.

In fact, one of the easiest ways to increase your intake is simply to make your meals a little more colorful. Add berries to breakfast, throw some peppers into your lunch, have broccoli with dinner or keep some fruit where you can see it when you’re looking for a snack. It doesn’t need to become another complicated health goal to keep track of.

Do You Need a Vitamin C Supplement?

If you eat a varied diet with plenty of fruit and vegetables, you may already be getting a good amount of vitamin C from food. But be honest with yourself, just how varied and balanced is your diet on a typical week?

Between busy mornings, lunches eaten at your desk and those evenings when dinner ends up being whatever is easiest, getting a good variety of fruit and vegetables every single day isn't always as simple as it sounds.

That’s where a vitamin C supplement can be a useful addition. It gives you a simple, convenient way to top up your daily intake, particularly on the days when your diet isn't quite as balanced as you'd like.

A Simple Addition to Your Everyday Routine

That is really what makes vitamin C so easy to include in your routine. You don't need to completely rethink your diet or add another complicated wellness habit to your list.

Enjoy your fruit and vegetables, make your meals as varied as you can and use a supplement to help support your daily vitamin C intake.

Vitamin C may have started off in our minds as the vitamin in oranges, but there’s a lot more to it than that. From collagen formation and iron absorption to immune function and antioxidant protection, it has a hand in some pretty important jobs behind the scenes.

It might not be the most exciting nutrient in your cupboard, but it is certainly one worth giving a little more credit.
