Vitamins are essential for the smooth functioning of the human organism. In principle, around 13 of these vitamins can even be described as vital. However, it is important to know that as many as 11 of them cannot be produced by the body itself and must be obtained through food.
This intake must be ensured so that all processes and tasks in the body can be handled. Otherwise, deficiency symptoms and various, very individual complaints can occur. So this question cannot be limited to 'the one' most important vitamin.

The 13 most important are:
• Vitamin A
• Biotin
• Vitamin B1
• Folic acid
• Vitamin B2
• Vitamin B12
• Niacin
• Vitamin C
• Pantothenic acid
• Vitamin D3
• Vitamin B6
• Vitamin E
• Vitamin K

Vitamins are important nutrients that the body needs to function properly. They are required for the proper development and function of cells, tissues and organs. They are also important for the body's metabolism and help it use the nutrients from food.

But how can you know whether you are getting enough vitamins? Here are a few signs to watch for:
• You are constantly tired: this could be a sign of iron deficiency. Iron helps transport oxygen to our cells. So if you are not getting enough of it, you will probably feel tired all the time.
• You get sick frequently: vitamin C is a powerful antioxidant that supports our immune system. If you often catch colds, this could be a sign that you are not getting enough vitamin C.
• You have difficulty concentrating: this could be a sign of vitamin B12 deficiency. Vitamin B12 helps our nervous system function properly. If you are not getting enough of it, it may be difficult for you to concentrate and focus.

If you are worried that you are not getting enough vitamins, talk to your doctor. They can order blood tests to check your vitamin levels and make sure you are getting the vitamins you need.

There are many different foods that claim to be the best when it comes to vitamins and minerals. But not all of them are equally good.
So what are the best foods to eat to get the most vitamins? Here are a few of the top candidates.
Good sources of:
• Vitamin A include fish, eggs, fortified milk, cheese, dark green leafy vegetables, and orange and yellow fruits and vegetables.
• Vitamin B1 include pork, whole grains, legumes, nuts and seeds.
• Vitamin B2 include milk, yogurt, cheese, eggs, lean meat and green leafy vegetables.

Dietary supplements can complement vitamin intake, but they do not replace a balanced diet. They should only be taken when needed.
