Can vitamin D increase energy levels
Vitamin C: why and in what form?
Vitamin C is essential for humans and one of the most studied vitamins there is. Some animals can synthesize vitamin C on their own, but humans cannot and must get enough vitamin C from their diet. Vitamin C is naturally found in vegetables and fruits, especially citrus fruits. Vitamins C is an antioxidant and thus acts as a protection against free radicals.
The first use of vitamin C was against scurvy, the disease that used to be common on long journeys, for example on ships. When it became known that oranges and lemons help prevent scurvy, ships took lemons on their voyages. Later it became known that sauerkraut is rich in vitamin C, prevents scurvy and has a much longer shelf life than lemons. The chemical name of vitamin C is ascorbic acid and is derived from the word "Scorbutus", which means scurvy (Nutrition Society 2009, Bender 2006).
Today vitamin C is also available in isolation. For example, vitamin C can be used as a dietary supplement and added to food. Taking vitamin C can be important in addition to a healthy and varied diet.
Vitamin C metabolism
As stated earlier, humans and some animals, such as monkeys and bats, cannot synthesize vitamin C on their own. They lack the enzyme gulonolactone oxidase, which can be used to synthesize vitamin C from glucose.
The absorption of vitamin C in the intestine can take place through active and passive absorption. With passive uptake by the intestinal cells, vitamin C is absorbed by the concentration gradient between the intestinal cell and the intestine. The concentration gradient then causes the passive diffusion of the molecule. Active uptake occurs through transporters that actively transport vitamin C into the cell. The cell uses energy for active transport.
Excess vitamin C stops passive transport and saturates the active transporters. The excess vitamin C is then not stored or absorbed, but excreted with the stool. In the large intestine, vitamin C attracts water, causing it to cause osmotic diarrhea.
In its role as an antioxidant, ascorbic acid is converted into dehydroascorbic acid, the reduced variant of vitamin C. The body can convert ascorbic acid to dehydroascorbic acid and vice versa, which allows ascorbic acid to be reused. For the cellular uptake of ascorbic acid, the cell uses so-called SVCT1 (sodium-dependent vitamin C transporter) to actively absorb vitamin C. The uptake of dehydroascorbic acid by the cell occurs through GLUT4 (glucose transporter type 4). As the name suggests, GLUT4 also transports glucose into the cell. In the event of an imbalance in glucose homeostasis, vitamin C homeostasis can also become imbalanced.
Vitamin C, what form?
Vitamin C supplements are available as pure ascorbic acid or as an ascorbate complex. Which form you choose best depends on the application and the duration of use.
Ascorbic acid is the most scientifically researched form of vitamin C and occurs naturally in our food. People with acid problems should best opt for the buffered ascorbate complex.
An ascorbate complex is a combination of ascorbic acid and minerals. The minerals act as a buffer, making them less acidic. This makes them gentler on the stomach and teeth. In addition, the minerals also contribute to the mineral status in the body. The mineral ratios in our ascorbate complex are based on the natural mineral ratios in the body's cells. In this way we stay close to nature.
Other forms of vitamin C preparations include liposomal vitamin C and Ester-C®. It is believed that liposomal vitamin C can temporarily increase vitamin C blood levels through an alternative absorption mechanism. Our R&D department does not consider the use and advantages of liposomal vitamin C to be sufficiently scientifically proven compared to our vitamin C products, which are very well-founded and have proven to be effective in practice.
Ester-C® is the patented ascorbate complex calcium ascorbate. It is therefore comparable to the Bonusan ascorbate complex. Bonusan does not use Ester-C® because it does not mimic the body's natural mineral ratio.
Dietary supplement: what form?
Vitamin C is available from Bonusan in powder form, as tablets and as chewable tablets.
Ascorbate powder is a high-dose application of vitamin C that dissolves easily in water. Mix it with your drinking water in a bottle for on the go or put it in a carafe on the table. That makes it easy to take extra vitamin C throughout the day. The ascorbate powder contains a natural orange aroma for a wonderfully fresh taste.
In tablet form, citrus bioflavonoids are added in addition to vitamin C. Citrus bioflavonoids occur naturally in citrus fruits and ensure good absorption of vitamin C. The tablets are available as ascorbic acid and ascorbate complex. The tablets are coated and therefore easy to swallow. One tablet contains 1000 mg of vitamin C and thus covers the daily requirement.
Vitamin C chewable tablets contain the ascorbate complex and natural orange aroma for a fresh taste. The use of the buffered ascorbate complex makes the chewable tablets more tooth-friendly. With 500 mg of vitamin C per tablet, they offer a simple and tasty way to meet your daily vitamin C requirements. For children and people who have difficulty swallowing tablets, chewable tablets can be a solution because they are easy to chew and swallow.
Vitamin C is added to various other products to help them work. Vitamin C often works synergistically with or in addition to many nutrients and herbs. In Bonusan Hämatonyl, for example, vitamin C helps improve iron absorption. Due to its wide field of application and its synergistic and complementary effect, vitamin C can be used strategically by therapists.
Applications of vitamin C
Vitamin C can be used very widely. The most common use of vitamin C is to support the body's defenses. Vitamin C has a positive influence on the immune system and supports the body's defenses. Zinc in the ascorbate complex works synergistically and supports the immune system.
One of the largest organs in the body is the skin. Vitamin C is important for the skin and for skin care from the inside. Vitamin C contributes to the formation of collagen, which helps strengthen the skin (from the inside out). In addition, vitamin C helps protect against the effects of environmental pollution and sunlight. An ascorbate complex, in which vitamin C is combined with minerals, supports this effect of vitamin C; Zinc, for example, helps to keep the skin healthy and to protect body cells from external influences.
During and after physical exertion, vitamin C helps maintain good defenses. In this way, vitamin C protects healthy cells and tissues. When exercising, Bonusan's vitamin C ascorbate powder can be dissolved in water so that vitamin C works as a supplement to antioxidants. In addition, vitamin C supports energy levels and helps release energy from food.
The heart pumps up to 4-5 liters of blood through the body every minute in order to supply and nourish muscles and organs with oxygen. Vitamin C is important for the blood vessels and good for supple / elastic veins. This is because vitamin C contributes to the formation of collagen, which is important in maintaining strong blood vessel walls.
Our body is supported by our bones. Vitamin C helps maintain strong bones. In addition, vitamin C plays a role in bone synthesis and in the synthesis / building of cartilage. Vitamins C also contribute to strong teeth. Zinc and magnesium in the ascorbate complex help maintain normal bones.
Not only physical health, but also mental health is important to maintaining overall health. Vitamin C has a positive effect on reducing tiredness and exhaustion. Vitamin C also contributes to mental resilience, a clear head and normal psychological function. Vitamin C contributes to brain and nerve functions that are involved in the thought process and activates the natural energy in the body. The ascorbate complex supports the energy level by adding magnesium.
Our energy balance is important to stay fit. Nutrients often work together, which optimizes their effects. Vitamin C contributes to a normal energy-producing metabolism because vitamin C supports the release of energy from fat, carbohydrates and proteins. The ascorbate complex helps because magnesium plays a role in the activity of certain enzymes that are involved in energy metabolism. In addition, vitamin C promotes the absorption of iron from meals / food and helps maintain vitamin E activity.
Knowledge in practice
We hope that this has made the importance of adequate vitamin C intake clear and that we have helped you choose the right form. The dosage depends on the application.
A daily intake of up to 2000 mg is recommended for healthy individuals. Therapeutic advice may vary. In the case of high doses and / or prolonged use, the use of a buffered, deacidified ascorbate complex is recommended.
Spread the intake over the day to ensure that the intestines absorb vitamin C evenly. The easiest way to achieve a distributed intake is with ascorbate powder. Ascorbate powder and the slightly lower-dose vitamin C chewable tablets from Bonusan are well suited for children and for people who do not want to swallow tablets.
If ingested in excess, osmotic diarrhea can occur. The dose then has to be reduced until the symptoms disappear (Gropper 2013).
