Not Sleeping Well? Might Want To Check Your Vitamin C levels!

Vitamin C has always been associated with better immunity – but did you know it does more than simply boost the immune system? It's true. Vitamin C also affects sleep. 

 The Relationship between Sleep and Vit-C

Studies have consistently highlighted an association between sleep and vitamin C. But what does vitamin C really do, and how does it affect our sleep?

Well, as it turns out, studies suggest that people who consume inadequate amounts of vitamin C have trouble either falling asleep or maintaining their sleep. In addition, those with low vitamin C levels in the body experience more disturbances during their sleep than those who meet the necessary amount of vitamin C.

For one, vitamin C helps lower our stress hormones. Note: stress could be the primary contributing reason why we are having trouble sleeping in the first place. 

Vitamin C can help reduce the amount of cortisol (i.e., the "stress hormone") in the body. Imaginably, less stress will undoubtedly translate into higher chances of higher-quality sleep. 

How can you make the most of Vitamin C? 

Vitamin C supplements can be an excellent way to ensure that you're meeting your daily nutrient requirements. But it isn't a replacement for a healthy, balanced, and nutritious diet. You should still try to get as much vitamin C from whole foods, like fruits and vegetables, as possible. 

Here are a few more tips about incorporating more vitamin C into your life:

  1. Take daily vitamin C with a diet rich in vitamins.
  2. Tweak your vitamin C intake based on your age and other conditions.

Top 10 Foods and Their Vitamin-C Amounts

While plenty of fruits and vegetables are known to have plenty of vitamin C, here are the top 10 foods packed with vitamin C per gram. 



Think of fruits packed with vitamin C, and you'll undoubtedly think of oranges. And for a good reason: a medium-sized orange contains about 70 milligrams of the nutrient, which is more than 70% of our required daily intake of vitamin C.


Besides the orange, a commonly-eaten fruit that packs plenty of vitamin C is the strawberry. Just one cup of strawberries (roughly 152 grams of fruit) is enough to help you meet your daily vitamin C requirements. 


A whole lemon, including the peel, contains about 82mg of Vitamin C. This is around 90% of our needed daily vitamin C. Wondering how you could make lemons more appetizing? Answer: make lemonade with them! 


The guava is a tropical fruit that is very rich in vitamin C. One guava can contain about 120 mg of vitamin C – more than what we need per day. 



Another tropical fruit that is rich in vitamin C is papaya. One papaya may contain about 85 mg of vitamin C, about 95% of the needed vitamin C daily.

Rose Hips 

Rose hips are small fruits harvested from certain rose plants species. Small as they may be, they actually pack quite a lot of vitamin C. Five rose hips should contain about 100mg of vitamin C, which is more than enough for our daily needs.


Peppers are said to contain more vitamin C than oranges. One cup of peppers contains about 190 mg of vitamin C, more than our needed daily vitamin C.

*Red peppers contain the highest amount of vitamin C compared to the yellow and green ones.


 The Kiwi fruit is also another fruit that contains more vitamin C than oranges. Two pieces of kiwi should have about 135 mg of vitamin C, which is enough for your daily needs. 


Kale is a leafy vegetable known to have more vitamin C than oranges. One serving of this vegetable is packed with various health-beneficial nutrients, including vitamin C (around 80mg).

Brussel Sprouts

Brussel Sprouts

These tiny little cabbages are so rich in vitamin C that they have more vitamin C than most citrus fruits, including the orange.  


A person who fails to meet your daily vitamin C requirements will have trouble sleeping. In contrast, someone with adequate vitamin C intake (and corresponding levels in the body) will be less likely to develop sleeping problems. This, in turn, highlights the importance of prioritizing the foods mentioned above in your diet; this will help you get the right amount of vitamin C in your body.
