How Much Vitamin C Is Too Much? Key Facts About Vitamin C Intake

How Much Vitamin C Is Too Much? Key Facts About Vitamin C Intake

Vitamin C, less commonly known as L-ascorbic acid, is a natural and essential nutrient found in numerous fruits and vegetables. It is responsible for the synthesis of particular neurotransmitters, collagen, and L-carnitine, and it also helps mediate metabolism of proteins.

Neurotransmitters are chemical messengers that orchestrate the execution of vital functions such as motor behavior, memory, learning, mood and sleep to name a few. Collagen is a structural protein and one of the primary components of connective tissues and L-carnitine is an amino acid derivative  that plays a role in fat metabolism.

Moreover, within the body vitamin C operates as a key antioxidant which is able to govern the generation of additional antioxidants such as vitamin E, and can further help absorption of other nutrients, mainly iron. [1] Since humans are incapable of endogenously manufacturing this water-soluble vitamin, acquiring it through diet is necessary for certain imperative biological functions to occur.

Can I take too much vitamin C?

While the importance of vitamin C intake may be fairly well-known, is there a limit to how much of this essential vitamin your body can handle?

Research says yes, and here’s why: as previously mentioned, vitamin C is water-soluble meaning it dissolves in water, and therefore is not stored in the body. [2] Rather, it is eliminated once excess amounts are reached, creating a false sense of comfort for ingesting too much vitamin C.

However, a recent study demonstrated the dangers of overdoing this nutrient. A team of British scientists conducted a study in which participants were administered more than 6 times the recommended daily dose for 6 weeks. They found that in such high doses vitamin C damaged DNA by converting iron stores into harmful ferrous iron which damages internal organs. [3]

Beyond this, numerous studies dating back to the 70s have indicated a correlation between excessive vitamin C and damage of genetic material. Further, the department of Food Science and Human Nutrition at Michigan State University has highlighted the potentiality of excess nutrient intake to result in toxicity. [4]

What does too much vitamin C look like?

Now that it has been established it’s possible and harmful to ingest too much vitamin C, how do you know if you are exceeding appropriate doses?

The main indicator is gastrointestinal distress: nausea, indigestion, fatigue, diarrhea, vomiting and upset stomach are a few examples of possible symptoms. [5] It also can manifest as hemochromatosis, hormone imbalances, kidney stones, and poor athletic performance. Hemochromatosis can be toxic and in severe cases result in organ failure, since it is the excessive production of iron in the body.

Hormone disruption can interfere with the first stages of pregnancy increasing the probability of birth defects since vitamin C can inhibit release of certain sex hormones. Kidney stones are mineral deposits that form within the kidneys resulting in severe pain. In the process of vitamin C metabolism, some are converted into oxalate which promotes the development of kidney stones.

Furthermore, too much vitamin C has been shown to reduce endurance in athletes through inhibition of the body’s cellular alterations while exercising.

How much should I take?

So vitamin C is a critical nutrient but when taken in excess causes extreme discomfort and harmful symptoms, how much are you supposed to ingest? The Food and Nutrition Board generated a recommended intake chart based on age and gender. [6]

Ultimately, the daily intake should be between 65 and 90 mg and harmful effects begin to appear with continued intake exceeding 500mg over long periods of time, and 2000mg for a single day.

How can I get vitamin C?

The best sources of vitamin C is through digestion of natural fruits and vegetables. Some primary examples and amount of vitamin C in 100g portion: [7]

  1. Strawberries: 58.8mg (98% of the daily value)
  2. Oranges: 53.2mg (89% of the daily value)
  3. Peppers: 183.5mg (306% of the daily value)
  4. Broccoli: 89.2mg (149% of the daily value)
  5. Papaya: 60.9mg (102% of the daily value)
  6. Lemon: 100mg (166% of the daily value)
  7. Kale: 120mg (200% of the daily value)
  8. Brussel sprouts: 85mg (142% of the daily value)
  9. Kiwi: 92.7mg (155% of the daily value)
  10. Peas: 60mg (100% of the daily value)

If cannot be consumed naturally, supplementation is available to meet the recommended daily dose.

10 Small Changes To Make Your House Feel Like A Home

10 Small Changes To Make Your House Feel Like A Home

Your house is more than just a building that you live in. It should be a home that makes you feel welcome as soon as you open the front door.

Making your house feel like a home is not something that simply happens on its own. You need to make some changes to a house when you move in, to give it that cozy, warm feeling that turns it into a true home. To help you speed the process, follow this guide to 10 small changes to make your house feel like a home.

1. Make the Windows Your Own

When you move into a home, they often come with boring Venetian blinds or less than attractive curtains.

One of the best ways you can instantly warm your home and make it showcase your style is to add some new window dressing. Adding beautiful curtains not only improves your home’s appearance, but it can also help to control the temperature.

2. Put up Some Art

If you have a lot of bare walls in your home, it will seem sterile no matter how beautiful your paint or wallpaper is.

Hanging art on the walls will instantly give it personality and make it feel like home.

3. Improve the Aroma

A house that is not filled with inviting smells will never feel like a home. There are loads of ways you can make your home smell nice. There are tons of air fresheners on the market you can use.

Incense and scented candles are a nice option as well. Don’t forget that baking in a home is also a great way to fill it with an aroma that instantly smells like home as soon as you open the front door.

4. Put out Lots of Pillows and Throws

A great way to make your home look warm and inviting is to place lots of pillows and throws out on the furniture. It is much better to have too many pillows than not enough.

There is nothing like the feeling of sinking into a cushiony pillow that feels like a cloud to make you feel like you are at home.

5. Instantly Class up Your Closet

If your closet is filled with wire or plastic hangers, it will never truly feel homey. To instantly make your closet feel classy, change out your old hangers for wooden ones.

Not only do they look great, but they are better for hanging your clothes as well.

6. Improve Your Air Quality

One of the most overlooked ways to make your house feel more like a home is to improve its air quality.

The easiest and best way to upgrade the air quality in your home is to change the old, dirty filters in your furnace regularly. Get some air filters delivered to your home so that you always have some on hand.

7. Fill it with Plants

Another way to improve the air quality in your home is to fill it with plants. You should have plants in every room of your home.

They help to improve the air quality and they look beautiful. As well as making your home appear homier, plants also help to boost your mood and lower your stress levels.

8. Change the Doorknobs

Most people don’t really give their doorknobs a second thought unless they are broken. That is a shame because changing your doorknobs is an easy way to add personality to your home.

Changing your old, boring doorknobs to new ones that are works of art will instantly brighten your home.

9. Upgrade Your Tub or Shower

There is nothing like luxuriating in a whirlpool bath or steam shower to make the cares of the day melt away. Your family deserves a bit of luxury when they are in their bathroom.

Install a new shower or tub today to make your bathroom worthy of a place in your home.

10. Fresh Cut Flowers

You can make any room in your house feel homier by placing a vase full of beautiful flowers in it. The gorgeous look and intoxicating aroma of fresh cut flowers will immediately brighten your day when you encounter them.

You don’t have to make all these changes at once. Try one or two a day though, and your house will feel like a home before you know it. The trick is to constantly keep adding these homey touches to make your home a place worthy of its name.
