Vitamin C Deficiency Score:

Likelihood of Deficiency: HIGH

(Probability: 84% or Higher)

Hey there, thanks for taking my quiz :).

My name is Eric Bakker (N.D.). Based on your score of there’s a HIGH probability you’re suffering from several signs of Vitamin C deficiency.

In Case You're Not Familiar With Me or My Credentials. . .

I'm a naturopathic physician based in New Zealand. I've specialized in the diagnosis & treatment of chronic problems such as autoimmunity, IBS & other gut disorders, & chronic fatigue syndrome for almost 35 years.

Having worked with over 60,000 patients from over 30 different countries either at my New Zealand clinic or via Skype. . .

I can say with good confidence I've seen almost every type of Vitamin deficiency and can help you with yours.

I also personally manage one of the largest natural health Youtube channels (called Eric Bakker - The Naturopath) with currently 2,145 in-depth videos on how to remedy a wide range of health problems that are often difficult to treat with conventional medicine and pharmaceutical drugs.

At the time of writing this, I have 11,727,126 video views.

This is the type of work I do.

Now enough about me, let's talk about Vitamin c deficiency. . .

//video: why is my body not absorbing vitamin c

Why Vitamin C Deficiencies Are NOT As Rare As You Think

There's a huge amount of confusion on the web about Vitamin C deficiency and how much you truly need.

Some websites say 20 mg of vitamin C a day is all you need because that's what it takes to avoid dying from scurvy. Others say it's beneficial to get 10,000 mg injected directly into your bloodstream via an IV. 

Many believe vitamin C deficiencies are totally impossible today and nobody gets them. 

But this isn't true.

You can have what's called a subclinical vitamin C deficiency (also called classical vitamin C deficiency in certain medical literature). A subclinical vitamin C deficiency means that while you're not majorly deficient, you're just deficient enough to cause a weakness within your immune system and other parts of your body.  

Subclinical vitamin C deficiencies are actually very common

And if you don't believe me, here's a screenshot from PubMed.

See the parts I highlighted? 

According to this 2009 study, in the early 90's, approximately 13% of the US population was Vitamin C deficient.

Between 2003 and 2004, that number dropped down to 7.1%.

You may think that study is outdated, but research shows Vitamin C deficiency has been on the rise again since 2009. One report published in 2016 by the Health and Social Care Information Centre in England, for example, stated that between 2009 and 2014, hospital admissions related to scurvy had increased by 27%.

The National Health Service of the UK also reported hospital visits for scurvy rose by 50.1% between 2010 and 2018.

So don't think this is just an old-fashioned sailor's issue or that Vitamin C deficiency is only a US problem.

It's very easy to become Vitamin C deficient

Vitamin C is a water-soluble nutrient with a low storage capacity within the body. So unless you're constantly getting Vitamin C it only takes a few weeks to become deficient.  

//video: What are the symptoms of vitamin c deficiency?

How To Tell if You Have a Subclinical Vitamin C Deficiency

Early symptoms of subclinical Vitamin C deficiency can include:

  • tiredness & fatigue
  • muscle and join pain
  • dry or rough skin
  • corkscrew & other misshapen body hair
  • mood swings, nausea & irritability
  • bleeding of the gums 

It can also cause more frequent infections because Vitamin C helps stimulate the production of white blood cells that attack bacteria. That means you get the flu, strep throat, or urinary tract infections more frequently. 

Nosebleeds are another sign as low Vitamin C results in weaker blood vessels because of lower collagen production. Anemia is also common because Vitamin C is necessary for iron absorption.

If untreated & allowed to progress you could be looking at:

  • Easy bruising (due to weakened blood vessels)
  • Slower healing of wounds
  • Swelling and discoloration of gums
  • Loose teeth, receding gums and ultimately tooth loss
  • Bright red spots around hair follicles
  • Weak bones & increased risk of osteoporosis

It can also cause unexpected weight gain. Several studies have found a link between low Vitamin C intake and higher body fat. Even normal-weight people tend have to have higher belly fat if their blood levels of Vitamin C are low. 

The skin and gums are usually the most affected.

There's also new evidence that low Vitamin C increases your chance of getting heart disease. 

This idea was originally put forward by Dr. Linus Pauling. In case you don't know, he was the biochemist who discovered the chemical bond. 

He later won a Nobel Prize in Chemistry for his research & another prize years later for peace activism. He remains the only person awarded with two unshared Nobel Prizes. 

All modern biochemistry and molecular biology is based on Dr. Pauling's work.

In 1989, he published a paper titled “A Unified Theory of Human Cardiovascular Disease.” In it he wrote that artery plaques were actually part of a repair process caused by damage due to low Vitamin C.

This happens because as Vitamin C levels drop, the walls surrounding arteries weaken.

Why? Because your collagen production goes down. Without collagen there's nothing to reinforce the walls. 

My friend Dr. Eric Berg describes it well in this short video:

In simple terms, low Vitamin C results in weak arteries. This results in tiny tears in the arterial wall. Your body then repairs the tear using cholesterol instead of collagen due to your low vitamin C. 

Back then doctors didn't believe Linus Pauling. They called him a quack.

Now of course we have studies which prove he was right. 

One study found that adults with lower blood levels of Vitamin C were nearly 40% more likely to develop heart failure within 15 years than those with the highest Vitamin C. And these were people with subclinical vitamin C deficiency. Their blood Vitamin C levels were lower but not so low that they had scurvy.

This is why Dr. Pauling was a big believer in taking large doses of Vitamin C daily. He credited it as the reason he was able to stay active until & work until the day he died at the age of 93 in 1994.

Why do some people get Vitamin C deficiency while others don't?

In my opinion, there are 3 major reasons why Vitamin C deficiency occurs. . .

The 3 Hidden Reasons People Get Vitamin C Deficiency

A lot of websites will tell you only smokers, heavy drinkers & people with anorexia get Vitamin C deficiency.

And this might be somewhat true for full-blown scurvy.

But I've had quite a lot of seemingly normal patients over the years who came to me with nutrient deficiencies including Vitamin C. 

These were the patients who would get colds several times a year. They would suffer from fatigue, skin issues & other health problems.

Many of them had already tried taking multivitamins to no effect.

And I'll explain why this happens in a moment.

In my opinion the 3 reasons why Vitamin C deficiency is on the rise are. . .

Reason #1: Many People Eat Processed Foods Deficient in Nutrients

People like to make fun of Americans for eating too much processed food. But really this problem is wide spread.

Experts in the UK, for example, blame the recent rise of scurvy on junk food, takeaway and microwave meals. They described these foods as being nutritionally "worse than the rations of WW2".

There's also the issue of Vitamin C being destroyed due to heat loss which almost nobody talks about. 

Percentage vitamin C lost during exposure to 140 degree heat

See this chart above? That's how much Vitamin C gets destroyed when exposed to just 140 degree heat. At 212 degrees (boiling temperature) the Vitamin C loss is 80%. Think about that the next time you drink a glass of pasteurized orange juice. 

Remember, all bottled juice has to get pasteurized (boiled) for it to be shelf stable.

So unless it's raw, you can't rely on these foods to get your Vitamin C.

Reason #2: Diets High In Sugar & Block Vitamin C Absorption

Vitamin C and sugar have similar chemical structures.

They bind to the same receptor sites on your cells & compete with one another for absorption. 

That means if there's more sugar in your system, less Vitamin C can get into your cells and vice versa.

That's why studies show taking Vitamin C helps curb sugar & carbohydrate cravings. 

And that's great except it also works in reverse. The more sugar you eat, the less Vitamin C your cells absorb.

Reason #3: Soil Depletion Has Caused Food Crops to Contain Less Vitamin C 

Back in 2004 the University of Texas published a large study where they revealed that the nutrient content of at least 43 different fruits & vegetables had declined significantly between 1950 and 1999.

The nutrients they found declined were protein, calcium, phosphorus, iron, riboflavin (Vitamin B2) and Vitamin C.

Another study found that just from 1975 and 1997, the average Vitamin C levels in 12 vegetables dropped 30%. Iron dropped 37%, Vitamin A dropped 21%, and calcium dropped 27%.

You have two 2 options if you want to avoid this problem.

Buy organic fruits & vegetables on a regular basis from local growers, or get a high-quality Vitamin C supplement

Should You Take Vitamin C Supplements Or Rely On Whole Foods?

Should you supplement with Vitamin C or simply eat more raw fruits and vegetables?

The answer is it depends on how deficient you are.

If your deficiency is mild, simply changing your diet may do the trick. But if your deficiency is more severe, taking a high-quality supplement is a must. Otherwise it may take months for your levels to return to normal. 

I'm not going to go too in depth into what foods contain the most Vitamin C.

You'll get that information if you watch the videos on this page. 

//video:  How is taking the vitamin c powder different from taking fruits/foods with a natural source of vitamin c?

So How Much Vitamin C Should You Supplement With?

The popular belief is that adults with adequate levels of Vitamin C should aim for 200 mg of Vitamin C a day. People with low levels are told to aim for 1,300 mg daily for a period of 1 month or longer until the deficiency is resolved.


But this is not the full picture.

Consider the following:

Humans are the one of the few mammals that can't produce Vitamin C on our own. Other mammals, for example goats, produce 13,000 mg of Vitamin C per day. 

Yes, 13,000 mg.

That's 50 times what humans are recommended to take and goats are smaller than humans. And that's not all.

When a goat is sick or stressed it's been found to produce 10 to 100 times the Vitamin C it does normally.

That means when a goat is sick, its body produces between 130,000 & 1.3 million mg of Vitamin C DAILY. Human studies have shown a similar higher utilization rate of Vitamin C. When a person is sick or under heavy stress, their body can handle up to 18,000 mg without discomfort (where normally they couldn't).


Yet we're told to take just 1,000 mg a day and hope we don't get sick. And we when we still get sick we ask "what the heck happened? I was taking Vitamin C".

This is why I recommend my patients take MORE.

Not 13,000 like goats get, but 3,000 mg of Vitamin C daily

//video:  Why I need 3000MG of Vitamin C? 1000 vs 2000 vs 3000 mg

Why 3,000 mg? Because that dosage, taken in the right form (meaning NOT as pure ascorbic acid) is the "sweet spot" for Vitamin C. It's the upper range that you can take & still have your body absorb it all.

3,000 mg is also the amount Dr. Linus Pauling recommended people take in 1970 when he published his book "Vitamin C and the Common Cold".  He also mentioned it later in his book "How to Live Longer and Feel Better".

Dr. Pauling later personally took up to 18,000 mg of Vitamin C per day, but we now know that's too much and anything above 4,000 to 5,000 mg per day tends to be excreted and not absorbed. 

How to Get 3,000 mg of Vitamin C Daily Without Side Effects

If you search online you'll see a variety of sources that say taking 2,000 to 3,000 mg per day of Vitamin C can cause diarrhea, nausea, stomach cramps, heartburn, headache and insomnia. 

And that's absolutely true if you take pure ascorbic acid.

Why? Because pure ascorbic acid is too acidic.

Ascorbic acid is what's called an "isolate."

This is NOT how Vitamin C is found in nature. In nature, foods high in Vitamin C are alkalizing. They're acidic on the surface. But when you eat these foods they have an alkalizing effect on your body. 

They break down into alkaline byproducts approximately 1 hour after you eat them.

This is because in nature, Vitamin C is always accompanied by the minerals calcium, magnesium and potassium. These minerals "buffer" the Vitamin C so that even if you take 3,000 mg a day, you get an alkalizing effect. That's why even if you eat 20 oranges you don't an upset stomach or any of the other side effects above.

That's why one of the most popular types of Vitamin C supplements right now are called Buffered Vitamin C.

They contain the minerals naturally found alongside Vitamin C that negate its acid forming effects.

Buffering Vitamin C also enhances the absorption of Vitamin C because the extra minerals slow down the speed at which Vitamin C travels through your body. This results in elevated Vitamin C levels for a longer period of time. 

This is why in January 2021 I released my own buffered Vitamin C powder called C-3K Plus.

I like to call C-3K Plus the Lamborghini of Vitamin C supplements.

This is a very unique formula which contains 3,000 mg of buffered Vitamin C per serving along with over 1 gram (1048mg) of what are called citrus bioflavanoids per serving.

What Are Citrus Bioflavanoids and Why Are They Necessary?

Citrus bioflavanoids are special antioxidants that are found alongside Vitamin C in nature. 

Researchers are now starting believe that any health benefits credited solely to Vitamin C may actually be due to the combined action of Vitamin C and bioflavonoids.

These bioflavanoids recycle the Vitamin C electron so that you end up with significantly higher amounts of Vitamin C in your system for longer.

Citrus bioflavanoids act synergistically with Vitamin C. They enhance the bio-availability and cellular retention of Vitamin C & amplify Vitamin C's health supporting properties.

Studies show citrus bioflavanoids may also:

  • Strengthen capillaries to boost blood flow
  • Reduce free radical damage
  • Protect collagen from age related deterioration
  • Help with allergies & asthma
  • Improve circulatory health
  • Speed up DNA repair in cells
  • Protect against heart disease
  • Protect nerve cells from damage
  • Help with iron absorption

The 3 citrus bioflavanoids used in C-3K Plus are Hesperidin, Rutin and Quercetin. You may have heard of these before. Particularly Quercetin which became very popular in 2020.

I've also added high doses of Vitamin A, Vitamin E, Zinc, and Copper to this formula.

//video:  What is the quality of the Vitamin C used in C-3K Plus? 

or - What type of Vitamin c is in C-3K Plus?

or - How did you come up with C-3K Plus formula? What is the science behind this formula?

That's why I call C-3k Plus the Lamborghini of Vitamin C supplements.

You get all these extras that boost the potency & absorption of Vitamin C. You get all the special vitamins, minerals & antioxidants found alongside vitamin C in nature.

You also get 6 different forms of Vitamin C and not just ascorbic acid. Most Vitamin C supplements give you ascorbic acid and nothing else. With C-3K Plus you get ascorbic acid plus magnesium ascorbate, calcium ascorbate, potassium ascorbate, zinc ascorbate and manganese ascorbate. 

As one person said to me "it's almost like a complete food!"

Whatever Vitamin C supplement you choose, pick a high-quality one.

Don't just go for a cheap ascorbic acid supplement. Nearly all the ascorbic acid supplements you see on Amazon and other places are made from GMO corn. Many of them also come from China which I'm sure you know doesn't have the highest quality controls when it comes to things like heavy metal contamination. 

C-3K Plus is both GMO-free and China-free.

Final Note From Eric Bakker N.D.

As you can tell, I'm very proud of my C-3K Plus formula.

This formula took me over 18 months to create & I truly believe it's the #1 Vitamin C supplement money can buy right now. 

C-3K Plus is not cheap, but great health is not cheap either. And believe me, the price is long forgotten when your health returns and your quality of life improves.

As for how many containers to get. . .

If your deficiency is mild & you only want to use C-3K Plus yourself, 1 or 2 may be enough. If you're more deficient, suffer from fatigue, bleeding gums or skin issues, or you want to protect your whole family, I usually say get 2 or 3 so you have extra containers ready to go. 

Remember, Vitamin C is the real deal. There's many studies proving it's effectiveness including one that showed up to a 50% reduction in common cold occurrence in individuals under high physical stress.
