Vitamins: Importance, functions & tips for optimal intake
Vitamins are essential nutrients necessary for numerous vital processes in our body. They support the metabolism, promote energy production, strengthen the immune system, and contribute to cell regeneration. There are 13 vitamins in total, each performing specific tasks – from maintaining vision through vitamin A to supporting collagen formation through vitamin C. Since the body cannot produce many of these vitamins itself, a balanced diet is crucial to ensure an adequate supply of these important nutrients. In this article, you will learn everything about fat-soluble and water-soluble vitamins and their importance for your health.
Vitamins: The little helpers for your health
Vitamins are among the most important helpers in your body, among other things. They are involved in numerous functions and ensure that everything works smoothly. Vitamins are essential nutrients and thus practically indispensable for almost all processes in our body. Each vitamin has its own tasks and functions. Vitamin C, for example, contributes to the normal function of the immune system, among other things. Vitamin A, on the other hand, contributes to the maintenance of normal vision.
- Vitamin A
- B vitamins: B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folic acid), B12 (cobalamin)
- Vitamin C
- Vitamin D
- Vitamin E
- Vitamin K
Our body cannot produce most of these vitamins itself. This means they should generally be obtained through food. If you ensure a varied and balanced diet, where you regularly eat fresh fruit, vegetables, whole grain products, nuts & seeds, you can usually provide yourself well with vitamins—aside from influencing factors such as gut health.
The path of vitamins: Absorption and utilization
Unlike macronutrients (carbohydrates, fats & proteins), vitamins do not provide direct energy. They support the body more indirectly. As soon as you eat something that contains vitamins, the body starts a complex process to release and utilize the nutrients from the food.
In the first step, the ingested food reaches the stomach, where it is broken down by stomach acid and with the help of enzymes. In this step, vitamins and other nutrients are separated from the food.
The actual absorption of vitamins and nutrients then takes place in the small intestine. The cells on the intestinal wall ensure that the released vitamins are filtered out of the food and pass through the intestinal wall into the bloodstream. Once the vitamins have reached the bloodstream, they are transported to the tissues and organs where they are needed.
Fat-soluble vitamins: Properties and benefits
- Vitamin E
- Vitamin D
- Vitamin K
- Vitamin A
The absorption of fat-soluble vitamins can only take place in the small intestine together with dietary fats. They are stored in fatty tissue and the liver, which means the body can use them over a longer period. They support numerous processes, including immune function, skin health, and bone density. They are found particularly in fat-rich foods such as fish, nuts, and vegetable oils.
Vitamin D is also known as the sunshine vitamin and represents a minor exception here.

Water-soluble vitamins: Why they are important
- Vitamin C
- B vitamins: B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folic acid), B12 (cobalamin)
Vitamin C contributes to normal immune system function and collagen formation, while B vitamins contribute to the reduction of fatigue and normal nerve functions. Since they are excreted via urine, they must be continuously obtained through the diet.
If regular intake of these vitamins via diet is not possible for various reasons, the additional intake of dietary supplements can be sensible.
Fat-soluble and water-soluble vitamins: What you should consider
When preparing vitamin C-rich foods, such as peppers or broccoli, you should pay attention to the correct preparation, as these vitamins are sensitive to heat. Boiling, frying, and steaming can reduce the vitamin C content, especially because the vitamins dissolve in the cooking water. To maintain the maximum nutrient content, it is advisable to eat these foods raw or gently cooked, for example by steaming at a low temperature.
Fat-soluble vitamins are somewhat more resistant to high temperatures than water-soluble ones, but they too can be destroyed by intense frying or deep-frying.
For optimal storage, you should keep vitamin-rich foods in a cool, dark place. Vitamin C and other water-soluble vitamins are particularly sensitive to light and oxygen. Fat-soluble vitamins can also be affected by these factors.
Conclusion
Vitamins are indispensable nutrients that play a key role in health. They support the metabolism, strengthen the immune system, and contribute to cell regeneration. The distinction between fat-soluble and water-soluble vitamins is important, as they have different functions and requirements regarding absorption and storage. A balanced diet rich in fresh fruit, vegetables, and healthy fats is the best way to optimally supply your body with vitamins. If an adequate supply through diet is not possible for various reasons, supplementation with appropriate dietary supplements can be sensible.
