Vitamin C is a vital nutrient for wellness. It is involved in many crucial body functions, including immune system functioning, and can neutralize harmful free radicals.

How Much Vitamin C Should You Take Daily?

The current recommended dietary allowance (RDA) for vitamin C is 90 mg/day for adult men and 75 mg/day for adult women. That said, breastfeeding mothers need an additional 45 mg/dl daily, while smokers need an extra 35 mg/dl.

The human body cannot produce vitamin C on its own. You have to get it from external sources (e.g., diet or supplements).

Thankfully, it appears that meeting your vitamin C needs is pretty easy, as long as you include a variety of fruits and vegetables in your diet.

What is Vitamin C Good for?

Vitamin C plays a role in tissue formation and is thus crucial in the body’s natural healing process. Plus, it’s one of the few antioxidants capable of protecting the body against oxidative damage (i.e., from free radicals). With smart diet choices, you can ensure that you get sufficient vitamin C daily.

Vitamin C Sources

Although your body cannot produce vitamin C on its own, it’s still pretty easy for you to meet your vitamin C needs through your diet. As long as you consume a variety of fruits and vegetables, you should be able to meet these needs. For instance, one medium orange provides you with almost 75% of your daily vitamin C recommended intake, while 160 grams of cooked broccoli provides 110%.

Other fruits and vegetables rich in vitamin C include:

  • Green pepper

  • Guava

  • Kiwi

  • Lemon

  • Red pepper

  • Strawberry

In general, eating a balanced, varied diet is all you need to meet your body’s daily macro and micro-nutrient needs. Yes, that includes carbohydrates, fat, and protein. That said, many factors like medications and environmental conditions (e.g. climate) may increase your daily vitamin C needs.

How Can You Test Vitamin C with Vivoo?

Vitamin C is an essential vitamin for wellness. The body doesn’t produce it on its own, which means we need to get it from external sources – mainly through the diet. Vitamin C can support the body’s defense system functions thanks to its potent antioxidant effects.

Since urinary vitamin C levels reflect dietary intake, measuring the amounts of vitamin C found in your urine sample offers you a straightforward way to determine whether you’re getting enough.

This is where Vivoo comes in. Vivoo lets you track your urinary vitamin C levels, and based on the results offers you personalized nutritional and lifestyle advice in only 90 seconds! That’s all the time it takes for you to prevent unwanted situations that impact your wellness and take control of your well-being.


How to Evaluate Possible Results?

A low urine vitamin C level occurs when the vitamin C levels in your urine are lower than average.

The body doesn’t store vitamin C.  Instead, it excretes excess amounts through urine. Only a tiny reserve of vitamin C remains in the body, which is why you need to regularly consume vitamin C to ensure your well-being.

  • Score: 5/10
  • Label: Low
  • Value: 0 mmol/L Vit-C

Symptoms of severe vitamin C deficiency can take months to develop. Symptoms of vitamin C deficiency include:

  • Broken hair
  • Dry Skin
  • Fatigue

Optimal urinary vitamin C levels mean that you are getting the right amount of vitamin C.

  • Score: 10/10
  • Label: Optimal
  • Value: 0.6 - 2.8  mmol/L Vit-C

Maintaining an optimal level helps with: 

  • Neutralizing free radicals (through its antioxidant effects)
  • Skin health
  • Wound healing

A high urine vitamin C level occurs when the vitamin C levels in the urine are higher than average.

  • Score: 8/10 and 6/10
  • Label: : High
  • Value:  0.67 - 6.58 mg/mg Mg/Cr

Taking in more vitamin C than is recommended is generally not harmful to your wellness. That’s because vitamin C is water-soluble, and excess amounts are excreted through the urine.That said, consuming too much vitamin C (i.e., above 2g/day) may lead to non-life-threatening side effects like: 

  • Changes in bowel movement 
  • Stomach cramps or bloating
  • Headache

What are the Normal Vitamin C Levels?

As mentioned earlier, adequate consumption of vitamin C helps you maintain your optimal wellness. That’s why it’s so important for you to keep an eye on the level of vitamin C in your body. Luckily, vitamin C levels can be easily detected in urine, so you can easily monitor your vitamin C levels through urine samples.

Excess vitamin C is rapidly excreted through the urine. Note that anywhere between 70-90% of dietary vitamin C (technical term: ascorbic acid) ends up being absorbed into the body.

An increase in vitamin C intake proportionally increases plasma concentrations, along with the rate of its excretion through urine. Of the 100 mg of vitamin C ingested daily, an average of 25 mg is passed out of the body through urine, which helps explain urinary vitamin C levels as a reflection of your dietary intake, and urinary vitamin C levels provide valuable insights into the body’s vitamin C balance.

However, since methods used in different testing approaches may vary, reference ranges can differ.

When you take a urine test with Vivoo, obtaining a value for your Vitamin C parameter between 0.6 and 2.8 mmol/L indicates that you have received sufficient Vitamin C.

Frequently Asked Question


What is the normal range for vitamin C in urine?

The normal range for vitamin C (ascorbic acid) in urine can vary depending on the units of measurement used. Typically, vitamin C levels in urine are reported in milligrams per deciliter (mg/dL) or milligrams per liter (mg/L).

Approximately 70–90% of vitamin C is absorbed in moderate intakes of 30–180 mg/day. In 30–60 mg daily doses, almost no vitamin C is excreted in urine within 24 hours. Having a daily dose of 100 mg results in 25% of the dose of vitamin C being excreted, and having a daily dose equal to or above 500 mg results in almost all vitamin C being excreted.

Higher or lower levels of vitamin C in urine may be indicative of dietary factors or certain health conditions. For example, very high levels of vitamin C in the urine could suggest excess consumption of vitamin C supplements or foods rich in vitamin C. On the other hand, low levels of vitamin C in the urine may indicate a deficiency in the diet (2).

What color is your urine when you take vitamin C?

When you take vitamin C supplements, your urine can turn a brighter or more yellowish color. This happens because vitamin C is water-soluble, and any extra vitamin C your body doesn't need gets flushed out through your urine.

It's generally not something to worry about if your urine looks different after taking vitamin C. However, if you see significant changes in your urine color or experience any unusual symptoms, it's a good idea to consult with a healthcare professional for guidance.

What causes high vitamin C in urine?

High levels of vitamin C in urine, can happen for a few reasons:

Too Much Vitamin C: When you consume a lot of vitamin C, either through supplements or foods like oranges, your body might get rid of the extra by sending it into your urine.

Certain Medications or Drugs: Some medications, like nonsteroidal anti-inflammatories , can also increase the amount of excreted vitamin C in your urine.

Certain Health Issues: Conditions like kidney ıssues can mess with how your kidneys handle vitamin C, leading to more of it being flushed out in your urine.

Having high vitamin C levels in your urine is not usually a big problem. But, taking extremely high doses of vitamin C supplements (over to 2g/day) can cause some tummy troubles and, in rare cases, kidney stones.

It's always a good idea to chat with a healthcare pro before taking super-high vitamin C supplements. They can help you make sure you're getting the right amount of this important vitamin. Or you can always check your vitamin C levels in the comfort of your home with Vivoo!
