Natural vitamin C should be taken every day. When eating daily meals, always ensure that all necessary vitamins are present in the food. This is often difficult because we do not always know the exact ingredients of the food.

For this reason, vitamin C supplements are a good help to cover the most important nutritional basics. Natural vitamin C in particular is very popular with customers who pay attention to a healthy and balanced diet. A daily intake of vitamin C is very helpful to strengthen the immune system and to stimulate metabolic processes.

Buying and evaluation criteria for Natural Vitamin C

In order to take the right products for a balanced diet, you should take a close look at all the criteria of Natural Vitamin C. To help you make an easy decision, you can find all the important aspects here.

In the next paragraphs you will learn how these criteria can be important for you.

Dosage form

Natural vitamin C is already available in many different forms. These are the dosage forms that are produced in the pharmaceutical industry:

Type Description
Effervescent tablets This tablet is dissolved or allowed to disintegrate in water. The resulting solution is drunk
Tablets Tablets containing pure vitamin C are taken with a sip of water.
Capsules In a capsule, the natural vitamin C is covered with a capsule shell. In most cases, the capsule shell consists of natural gelatine.
Powder Pure vitamin C powder should only be taken if recommended or prescribed by your doctor. The powder is mixed with a glass of water and drunk.

Natural vitamin C is very sensitive to light and must be stored properly. Most consumers prefer to use effervescent tablets as a form of natural vitamin C. This is because effervescent tablets are easy to dissolve and drink. This is because effervescent tablets are easy to dissolve and drink.

Natural vitamin C is sensitive to heat and light. Proper storage is therefore very important. This applies to food supplements as well as foodstuffs.

Quality

You have probably seen most quality seals when shopping for food. Natural vitamin C supplements are also identified by certain quality seals, such as the organic seal. Basically, you can rule out impurities or harmful ingredients in quality-tested food supplements. We have listed the most significant quality seals in Germany here:

  • Regional window: Companies can use the regional window to identify their regional products in Germany.
  • Animal welfare label: Foodstuffs of animal origin are labelled with this seal to indicate that they have been produced in accordance with particularly strict animal welfare standards.
  • Organic seal and EU organic logo: This German seal identifies foodstuffs that have been produced in accordance with the criteria of EU legislation on organic farming.
  • Ohne Gentechnik: Products with this seal have been produced without genetic engineering.
  • Fairtrade seal: This seal identifies fairly traded products that have been produced under special social and ecological conditions.

Of course, it is also important to pay attention to the country of manufacture. With trustworthy quality seals, the country of manufacture is secondary.

The country of production can also provide information about the quality of the natural vitamin C.

While we are familiar with quality seals from Germany, and can quickly access information about natural vitamin C preparations, products from other countries with no or foreign seals are not recommended.

Taste

To make the taste of natural vitamin C more pleasant, flavourings are added in some preparations. Flavourings make food supplements more pleasant to consume. Flavourings can be made from natural or synthetic raw materials. So-called reaction flavourings are made from sugar and amino acids.

If you want to take natural vitamin C, you should choose supplements without any flavourings. If you do not want to give up a pleasant taste, natural flavourings are preferable to synthetic ones.

Naturalness

Natural vitamin C usually has no other additives and is therefore highly bioavailable. Natural vitamin C is therefore easier for the body to use. Unlike artificial vitamin C, which is chemically produced, natural vitamin C is obtained from food.

Natural vitamin C should be free of additives.

Artificial additives are not tolerated by everyone in the same way. Other artificial additives such as colourings or preservatives can trigger allergic reactions in some people. Natural vitamin C, however, should be free of additives and not contain any chemical traces.

Guide: Frequently asked questions about natural vitamin C

Here we have answered the most frequently asked questions about natural vitamin C. The questions and answers in our guide will give you a better overview so you can make sure that natural vitamin C is right for you.

Natürliches Vitamin C

Oranges and kiwis contain plenty of natural vitamin C. Therefore, a balanced diet with enough fruit is very important. If there are days when you haven't eaten that much fruit, vitamin C supplements can be very helpful. (Image source: DDP/ Unsplash)

What is natural vitamin C and how does it work?

Vitamin C cannot be produced by the human body itself, nor is it possible for the human body to store vitamin C over a longer period of time. Therefore, a daily intake of vitamin C is important to strengthen the bones and the immune system.

Furthermore, natural vitamin C has positive effects on high blood pressure and the skin. According to studies, vitamin C combats the following symptoms and diseases, among others:

  • Listlessness, chronic fatigue, lack of performance
  • Depression
  • Chronic diseases, immune deficiency
  • Joint and limb pain and cartilage degeneration (1)

As already mentioned, natural vitamin C can be better absorbed by the body than chemical vitamin C. Natural vitamin C is therefore also more beneficial to health.

Effect on bones

Studies have shown that taking the right amount of pure vitamin C every day can help prevent the bone disease osteoporosis. The Framingham Osteoporosis Study showed a link between vitamin C intake and bone density, especially in older men. The more vitamin C the participants in the study consumed, the less bone loss was seen over the four years of observation. (2)

Effect on the immune system

It is currently well known that natural vitamin C strengthens the immune system. Especially for children and older people, the vitamin shows great effects.

In a placebo-controlled double-blind study, it was found that children who took one or two grams of vitamin C were less likely to stay away from school than other children. (3)

Furthermore, natural vitamin C can prevent and treat specific age-related diseases in older women. (4) Furthermore, vitamin C is increasingly prescribed as a preventive against colds. According to one study, natural vitamin C shortens colds and weakens the strength of some diseases. (5)

Another study confirmed that taking the right amount of vitamin C daily reduces the incidence of colds. (6)

Effect on blood pressure

On blood pressure, natural vitamin C can produce great effects: in 2012, doctors found in a study that vitamin C supplements can very quickly lower patients' high blood pressure. According to the study, the effects of vitamin C on blood pressure are more pronounced in people with hypertension. (7)

Anti-ageing effect

Natural vitamin C is also popular in the cosmetics industry. Numerous anti-ageing products, anti-pigments and UV-protective products containing vitamin C are sold in cosmetics and drugstores.

Vitamin C is one of the most powerful antioxidants for the skin. By increasing collagen synthesis, stabilising collagen fibres and reducing collagen degradation, the vitamin is often used in anti-ageing care. (8)

Effects for asthma patients

Natural vitamin C can also be very useful for people who suffer from asthma. Studies show that an increased intake of antioxidants can reduce asthma. Especially in male study candidates, the results were very significant. (9)

How should natural vitamin C be dosed?

Everyone should get enough vitamin C every day. The daily requirement of natural vitamin C for an adult is 95 to 110 mg. Generally speaking, this is a rather cautious and low reading.

A person's requirement will increase depending on how much exercise they do. In food supplements there are different dosages of the vitamin, for example you can buy natural vitamin C in the pharmacy up to 5000 mg per dose.

Although this is a very high dosage, not all of it is absorbed by the body: Excess vitamins are excreted through the urine and stool. However, it is important not to take excessive amounts of natural vitamin C. An overdose could lead to acidification of the urine and the formation of kidney stones. (10)

Always make sure you only take as much vitamin C as you need. An overdose can cause digestive problems and diarrhoea. (Image source: Shari Pina Messina/ Unsplash)

A higher dosage should therefore only be used if it has been prescribed by a doctor.

How much does natural vitamin C cost?

Natural vitamin C preparations are cheaper the higher the dosage. To make a meaningful price comparison, the preparations should therefore be in the same dosage category. Here you will find a table with the prices of packs containing approx. 30 tablets (100 ml) or capsules of natural vitamin C.

Type Price
Tablets (30 pcs.) ca. 5-20 Euro
Capsules (30 pcs.) ca. 6-20 Euro
Spray/Drops (100 ml) ca. 12-25 Euro
Injection (100 ml) 3-40 Euro

Injections of natural vitamin C should only be given if a doctor prescribes it.

What types of natural vitamin C are there?

Natural vitamin C is abundant in fruits when they are eaten raw. For people who do not get enough vitamin C in their daily life, there are plenty of supplements and preparations that make it possible to supply the body with natural vitamin C. Preparations are basically available in two different dosage forms:

Type Description
Natural vitamin C in liquid form Liposomal vitamin C can be taken in the form of drops.
Natural vitamin C as capsules or tablets The vitamin can be taken either by capsules or by tablets. Effervescent tablets containing natural vitamin C are also available.

The advantages and disadvantages of these preparations can be found here.

Liposomal natural vitamin C

Because natural vitamin C is a water-soluble vitamin, unneeded amounts are excreted from your body. However, this also has a disadvantage: the body often finds it difficult to absorb water-soluble vitamins from food.

For this reason, many customers like to turn to liposomal natural vitamin C. Liposomes are called small bubbles or transport beads that can carry the vitamin directly into your body.

In addition to the absorption of the natural vitamin C, the duration of action is also increased. Liposomal food supplements are therefore more effective and last much longer.

Advantages
  • Avoids increased degradation of the active ingredients
  • Can be added to food
  • Ensures a balanced vitamin intake
Disadvantages
  • Can become thick if stored incorrectly
  • Usually has a bitter taste

If you want to use natural vitamin C in liquid form, you should pay close attention to the dosage recommendations on the package. As liposomal vitamin C is more effective than conventional natural vitamin C preparations, the chance of overdosing is also higher.

Natural vitamin C tablets, capsules or effervescent tablets

Natural vitamin C is also available in the form of capsules, tablets or effervescent tablets. For people who have no problems swallowing capsules or tablets, there are numerous preparations that are offered in this dosage form.

According to our research, however, effervescent tablets with natural vitamin C are the most popular preparation. Effervescent tablets with natural vitamin C are particularly suitable for patients with swallowing difficulties and children. The preparation can be quickly dissolved in water and taken into the body.

Advantages
  • Easy to consume
  • Can be consumed by anyone and everyone
  • No bitter aftertaste
Disadvantages
  • Sensitive to moisture
  • Cannot be consumed without water

Besides natural vitamin C, effervescent tablets contain other excipients such as sweeteners, binders, preservatives and colourings.

What is the alternative to natural vitamin C?

If you want to take vitamin C, you do not necessarily have to use natural vitamin C. You can also take vitamin C supplements. Preparations with vitamin C can also consist of pure ascorbic acid or mixed forms. You can find more information about these vitamin C forms here:

Alternative Scientific situation Explanation
Pure ascorbic acid Unlike natural vitamin C, pure ascorbic acid does not contain as many important plant substances and enzymes Pure ascorbic acid looks like natural vitamin C from the outside. Natural vitamin C contains many more plant substances and enzymes. Furthermore, pure ascorbic acid is isolated and concentrated, so an excess can quickly develop
Mixed forms Mixed form preparations combine pure ascorbic acid with natural vitamin C. Mixed forms combine the advantages of natural vitamin C with low-cost ascorbic acid. The pure ascorbic acid is added to keep the price lower.

Since no additives are added to natural vitamin C, it is easy to see that the natural variety is more beneficial to health. Preparations of ascorbic acid and mixed forms are comparatively cheaper than natural vitamin C.
