Supplement marketers go into overdrive during cold and flu season, advertising products that promise to decrease your odds of getting sick. Vitamin C is among the best-known, most accessible antioxidants that have been touted to help prevent you from getting sick.

How Does Vitamin C Affect The Body

How much Vitamin C is too much?

Vitamin C is a powerhouse nutrient the body shouldn’t go without. It has the ability to repair tissue, stimulate the production of white blood cells, and reduce inflammation and other physical effects of stress. Vitamin C can also lower your risk of stroke and help with iron absorption.

“Vitamin C is a critical antioxidant that is involved in the structure and function of nearly every part of the body,” says Beverly Goode-Kanawati, DO, and director and founder of Beverly Medical Center in Raleigh, NC. “For example, vitamin C is needed to create collagen which is the underpinning of structures for everything from the skin to bones.”

Since the body doesn’t create vitamin C on its own, you need to get it in your diet or in supplemental form vitamin C is found in a variety of foods, including:

  • Citrus fruits
  • Sleeping problems
  • Skin irritation and the formation of blackheads

Because vitamin C is a water-soluble vitamin, you’re less likely to experience vitamin toxicity than you would with potassium, for example. This is because water-soluble vitamins dissolve in water and are absorbed in the small intestine. In other words, your body uses what it needs from the vitamin and discards the rest through your urine.

“The reason is that many supplements contain four to 20 times higher doses than the recommended daily intake,” Marinov says.

Can A Vitamin C Supplement Really Keep You From Getting Sick

Despite it’s popularity as a remedy for the common cold, there’s actually no evidence to suggest that a large dose of vitamin C can actually prevent one or any other type of illness, for that matter.

And while you may have heard that a large dose of vitamin C can slightly reduce the duration of a cold, this only applies if you take that large dose every singleday of the year even when you’re not sick. This means that if you rip that vitamin C packet open after your symptoms begin, there’s no evidence to suggest it’ll actually shorten the length of your cold.

As it turns out, boosting your immune system is more complicated than just downing a packet or a pill. And while vitamin C does play an important role in supporting your immune system, it doesn’t take megadoses like the ones found in supplements which often contain 1667% more vitamin C than you actually need every day.

Plus unlike dogs and cats, human are unique mammals in that we dont internally create this vitamin. We literally dont have a choice we need to get it from dietary sources.

What we do have a choice on though is how much we consume. We know how much is needed to avoid scurvy and deficiency symptoms and its the amount beyond that where the question mark remains is more necessarily better?

A recent scientific review of its antioxidant and pro-oxidant activity in oral health sums up the current mindset quite well:

The data validates the role of Vitamin C as an antioxidant under physiologic conditions exhibiting a cross over role as a pro-oxidant in pathological conditions. Further studies are required to substantiate its pro-oxidant activity to draw concrete conclusions.

While that review was specific to oral health, the scientists factored in generalized pro-oxidant vs. antioxidant research, too.
