Vitamin C 1000 Gold is by far the most well-known vitamin. Vitamin C 1000 helps to maintain the resistance. However, vitamin C has way more lesser-known functions. Vitamin C is used in the formation of collages, which is important for the bones, for example. Vitamin C is important for the nervous system and energy metabolism as well. Vitamin C – as an oxidant – contributes to the protection of healthy cells. Fruit and vegetables are good sources of Vitamin C 1000 Gold. A varied diet provides the basic need of Vitamin C 1000 Gold. Athletes strain their bodies heavier. The ones who put their body to the test on a daily basis may choose to use additional Vitamin C 1000 Gold. Vitamin C 1000 Gold contributes to maintaining a good resistance during and after training and sports performances (at least 200 mg of vitamin C per day, in addition to the recommended daily intake of vitamin C). For that reason it is important for athletes and the coaching team to pay extra attention to Vitamin C 1000 Gold during heavy exercise.

It is a known phenomenon in the sports world: altitude training (a minimum of 3 weeks of altitude training). At high altitude the air pressure and oxygen pressure are lower. In order to deal with this, the body adjusts itself by producing more red blood cells. Vitamin C 1000 Gold increases the amount of iron in the blood. It could be useful to take a Vitamin C 1000 supplement during altitude training. The reason for using Vitamin C 1000 is that it increases the iron absorption.

Vitamin C 1000 Gold
NOC*NSG advises athletes and coaches to use a supplement in certain cases; for example during change of environment (smog, altitude, traveling). These supplements have to meet the following characteristics: 100-300 mg of vitamin C per tablet (no time-releases formula).

Vitamin C 1000 Gold is endowed with the NZVT logo. NZVT is an abbreviation of the ‘Nederlands Zekerheidssysteem Voedingssupplementen Topsport’ (Anti-Doping Authority for the Netherlands.) This certification guarantees the athlete that the dietary supplement is free of doping.

The daily vitamin C intake of a human completely depends on the diet (fruit, vegetables, potatoes), because the body cannot synthesize vitamin C itself. Vitamin C is involved in many processes in the body. It has a strong anti-oxidative effect and helps protect the body’s cell and tissue structures against excessive amounts of free radicals (oxidative stress) that are formed as a result of exposure to smoke, alcohol, environmental pollution, sunlight, stress and also heavy sports exercises.

In addition to the anti-oxidative effect, vitamin C in the body also acts as a coenzyme. It helps other enzymes to do their work: forming collaged and connective tissue that is necessary for the formation of skin, bone, tendons, ligaments, blood vessels and cartilage. As a co-enzyme it is also involved in the formation of carnitine, which is essential for the transport of fatty acids in the mitochondria and energy production. Vitamin C is also required for the biosynthesis of catecholamine such as dopamine and norepinephrine.

Vitamin C supports a range of different body processes, but it is good to know that there are also situations where it is good to be cautious with vitamin C. In the past ten years several studies have been published which show that antioxidants (vitamin C is one of them) can inhibit training adaption if large quantities are taken in. At first it was thought that it was good to use vitamin C in combination with training to stop the free radicals and protect the cells against oxidative stress. Now it has become clear that the formation of free radicals during a training are required to improve the aerobic metabolism (production of mitochondria). High dosages of vitamin C or taking in antioxidants neutralizes these free radicals, which reduces the effect of the training or makes it have no effect at all.

It depends on the situation if additional vitamin C is useful or not. During training periods, the intake of large doses should be limited. Based on current research an intake of 200-250 mg vitamin C a day through food (about 5 portions of fruit and vegetables) suffices for tissue saturation, reduction of oxidative stress and to stabilize the vitamin C levels in the immune cells without affecting the training (Levine 1999, Braakhuis 2012). When the body is exposed to excessive stress, which happens when falling ill or during training internships, a higher vitamin C intake can be beneficial (Braakhuis 2012).

Vitamin c intake in the netherlands and its athletes

  • The average intake through a Dutch diet is 73-96 mg for men and 82-94 mg for women (Dutch Food Consumption Survey 2007-2010).
  • 12-28% of the Dutch adults take in less than 75 mg vitamin C a day (Dutch Food Consumption Survey 2007-2010).

A cold and vitamin C

  • People who make strenuous physical efforts or exert in the cold benefit from additional vitamin C. An intake of 250-1000 mg appears to reduce the risk of a cold by half (Hemilä 1996, 2013 and 2017).
  • Furthermore, a systematic review shows that vitamin C reduces the duration of the cold by an average of 8% (3-12%) and reduces its severity (Hemilä 2013), although this was not always the case in follow-up studies with patients.
  • The dosage of the vitamin C seems to play a role in how much it can shorten the duration of the illness. High dosages (6000-8000 mg/day) show a decrease in the duration of the illness, whereas this is not observed with a dosage of 3000-4000 mg/day (Hemilä 2017). That is why it is worthwhile to test the effect of vitamin C on athletes on an individual basis.
  • It is also worth mentioning that a vitamin C supplement does not reduce the risk of a cold amongst the general population (meta-analysis Hemilä 2013).

Advice vitamin C during daily training

  • An intake of 200 mg per day at a value of 70 μmol/L (Levine 1996) is enough to saturate the plasma of a healthy individual. A higher intake will have no effect on healthy people.
  • Vitamin C supplementation is not recommended in combination with aerobic and strength training. Multiple studies show that the effect of a training is inhibited when the intake is 1000 mg or higher (Gomez-Cabrera 2008, Paulsen 2014, Merry 2015).
  • A daily intake of 200-250 mg vitamin C, which is 5 portions of vegetables and fruit, is enough to reduce oxidative stress without inhibiting the effect of a training (Braakhuis 2012, Hemilä 2017).

Other situations in which vitamin C can be used

  • In case of an inadequate vitamin C intake (e.g. due to a strict diet).
  • At training camps, altitude training or other situations in which the body has to deal with extra (oxidative) stress.
  • When exposed to harmful substances such as smog, smoke and UV radiation. For example when competitions or tournaments take place in an area where there is a lot of smog.
  • During reduced iron values. Vitamin C ensures a better iron absorption (non-heme iron from plant sources).
  • When wounded or injured additional vitamin C can be taken for the formation of collagen.
