Vitamin C is among the most essential nutrients we need for the proper function of various processes that take place in our bodies.
From facilitating energy metabolism in our cells to collagen synthesis and immune system health, vitamin C does so much to keep us healthy.
Taking vitamin C supplements is one of the most convenient ways to intake larger doses of this essential vitamin, but is it the best?
There is evidence that dietary intake of vitamin C (e.g., eating more fresh fruits and vegetables) leads to better health outcomes.
However, in this review of the current literature on the subject, the conclusion essentially says more research is needed to determine whether vitamin C supplements or dietary vitamin C intake provide the most benefits.
With that being said, if you’re looking to improve your health and get more essential nutrients, eating a varied diet packed with fresh whole foods can only help you.
Sweet red bell peppers have the highest concentration of vitamin C per serving of any fruit or vegetable.
To get the most nutritional benefits from this delicious veg, you should eat it raw because vitamin C is easily destroyed by heat.
We recommend you add it to sandwiches for an extra crunch or dip it in hummus for a protein and nutrient-packed snack.

Orange juice is one of the easiest ways to get in your daily serving of vitamin C alongside a healthy breakfast.

Brussels sprouts have experienced a bit of a renaissance in recent years as many have realized they don’t have to be tasteless, bitter balls of leaves.
Nowadays, plenty of recipes explain exactly how to make these a satisfying side for any meal.
Roast them in the oven with a drizzle of olive oil and seasonings, or throw some bacon into the sautee pan as you cook them––if this doesn’t make you a sprouts believer, nothing will.
Best of all, you can get your whole daily serving of vitamin C with just a handful of Brussels sprouts.

Some might assume that the health benefits of tomato juice begin and end with a Bloody Mary––commonly espoused as a hangover cure.

Vitamin C (l-ascorbic acid) is essential for a healthy immune system, cellular health, iron absorption, energy metabolism, wound healing, and collagen production.
However, mounting evidence shows that raising your plasma vitamin C levels (the amount of vitamin C present in your blood) can lead to additional health benefits from its antioxidant properties, improve immune system response against illnesses, and reduce perceived levels of fatigue and stress.
The effects each individual will feel from consuming vitamin C supplements or increasing dietary intake will vary depending on whether or not you are deficient.
However, higher doses of vitamin C can improve immune function––reducing the length and severity of illnesses like the common cold––and reduce fatigue resulting from mild to moderate vitamin C deficiency.
Most of the literature and studies on vitamin C and its benefits agree that dietary intake (as opposed to just supplementation) leads to more significant health benefits since you will likely consume more nutrients overall with an improved diet.
Amount of vitamin C you should be consuming daily (pregnant and breastfeeding is more)
An adequate intake of vitamin C is at least 75 to 90mg per day for women and men, respectively.
If you are pregnant or breastfeeding, you should increase this by at least half––85mg if pregnant and 120mg if breastfeeding.
However, even a slightly increased dietary intake of vitamin C to between 100 to 200mg could help further improve immune system function.
The upper limit of vitamin C intake for adults is 2,000mg per day.
Doses above this amount can interfere with certain medications and cause some side effects, such as upset stomach, diarrhea, and, rarely, kidney stones.
Vitamin C is a water-soluble vitamin, meaning that it is dissolved in water and is easily absorbed into the body. However, like every other water-soluble vitamin, this makes it a bit harder for our bodies to hold onto vitamin C, so we must constantly eat it to keep our levels at an appropriate level. No foods help improve this absorption, per se, but eating some foods raw, such as bell peppers and cauliflower, can preserve the available nutrients.
The food highest in vitamin C per serving is red bell peppers. One ½ cup serving contains 106% of your recommended daily vitamin C.
Eggs contain many vitamins and other nutrients, but they do not have any vitamin C. This could be because chickens can synthesize vitamin C from glucose.
