Vitamins during a diet are one of the conditions not only for a beautiful figure, but also for a healthy body. Let's consider what vitamins should be taken during a diet. And also how to choose a vitamin complex for a particular type of diet and dietary restrictions in order to lose weight.
Vitamins during a diet are a rule that everyone who has decided on certain dietary restrictions to improve their figure or is on a diet according to medical recommendations should follow. Thus, according to medical research, in order for the body not to feel the need for vitamins and minerals, the daily diet should be about 5000 kcal. At the same time, most of the diet is vegetables, cereals, meat and fruits. Of course, with such a caloric content of food, there is no need to talk about weight loss. Therefore, for those who are on diets, special vitamin complexes have been developed that supply the body with all the minerals, microelements and vitamins necessary for full functioning.
The full functioning of the body, as well as many processes occurring in it, cannot do without minerals and vitamins. And this is not surprising, since vitamins play one of the most important roles in the functioning of the body. It is the presence of vitamins and minerals that helps to lose weight. Nutritionists have proven that the process of weight loss can be improved and accelerated with the help of vitamins. In addition, a complex of nutrients protects the body from the effects of unfavorable factors (environment, stress, infections and much more). Vitamins strengthen the immune system and have a positive effect on performance.
Since the diet is an unbalanced diet, that is, a diet with restrictions (during the diet, the body does not receive the necessary nutrients), it is necessary to take vitamin complexes. But choosing the right vitamin preparation is not so easy. Since today, many drugs are presented that contain certain components for the full functioning of the body. All this suggests that vitamins and diet are inseparable concepts.
Vitamins during diet
Vitamins during a diet are the key to maintaining a healthy body and creating a beautiful body. Let's consider what vitamins the human body needs during the process of losing weight, that is, during a diet.
- Vitamin C (ascorbic acid) – lowers cholesterol levels, participates in the process of transforming glucose into energy, which is necessary for a full life and performance. The vitamin is necessary to protect the body from atherosclerosis and heart disease. Lack of vitamin C is constant fatigue, slow healing of wounds, bleeding gums, dizziness.
- Vitamin D – strengthens bones, helps absorb calcium. Responsible for fat production processes in the human body. The vitamin is involved in the treatment of cancer and protects against rickets.
- B vitamins – participate in the processes of digestion and metabolism. Transform energy from the food we receive, i.e. proteins, fats and carbohydrates. B vitamins accelerate metabolic processes, enhance the protective functions of the immune and nervous systems, and maintain muscle tone in the body. A lack of vitamin B is the cause of headaches, bad mood, anxiety, stomach upset and cardiovascular diseases.
- Omega-3 (polyunsaturated fatty acids) – reduces hunger pangs and is an excellent antidepressant. It is not produced by the body, so it must come from food.
- Magnesium – controls the process of energy production and activates metabolism. Protects against metabolic disorders during periods of dietary restrictions.
- Vitamin E – is responsible for the normal functioning of the endocrine system and sex glands. Ensures the smooth functioning of the immune system and increases its protective functions.
The above vitamins are only part of what the human body should receive for proper functioning. A sharp weight loss and dietary restrictions are the cause of malfunctions in the body. Since the body stops receiving the vitamins, minerals, microelements and other useful substances necessary for normal functioning. Because of this, the body begins to break down its own fats, which leads to weight loss. But, the loss of accumulated vitamins by the body is not replenished, and this causes complications: hair loss, deterioration of vision, brittle nails, iron deficiency anemia and much more. To prevent this from happening, and the diet does not cause deterioration in health, it is necessary to take vitamins. The choice of vitamins depends entirely on the type of diet.
What vitamins should I take when on a diet?
What vitamins should you take when dieting and are there any dangers to your body if you lack nutrients? This is the first and main question that everyone who goes on a diet should ask themselves. Almost all vitamin complexes for losing weight include B vitamins, antioxidants and thermogenics (fat burners and metabolism boosters). This is due to the fact that no diet provides the body with the amount of nutrients it needs to function normally.
For example, no diet provides the body with a daily dose of vitamin A. Vitamin A is responsible for normal muscle growth, skin elasticity and firmness, and eye health. Vitamin A deficiency is the cause of flabby skin and difficulties during physical activity. Vitamin E maintains skin elasticity, accelerates regeneration processes, and calms the nervous system. B vitamins improve carbohydrate metabolism and protect the body's cells from toxins and other harmful substances. Vitamin B1 reduces appetite and normalizes blood sugar levels. It is because of these beneficial properties that B vitamins are present in almost all dietary supplements and vitamin complexes.
When on a diet, you need to take vitamins B2 and B12, as they maintain hemoglobin at a normal level. These vitamins are essential for those who follow a vegetarian diet. Vitamin B6 helps muscles recover quickly after exercise, so it must also be taken during a diet. A mandatory vitamin for a limited diet should be vitamin C. Ascorbic acid is a powerful antioxidant that strengthens the immune system. All of the above vitamins must be taken during a diet, as they ensure the proper functioning of the body.
But do not forget that there is a certain category of people who are prohibited from dieting and restricting their diet, even if they take vitamins. Diets are contraindicated for:
- Pregnant women - expectant mothers are prohibited from dieting. This is explained by the fact that the lack of vitamins and minerals negatively affects the process of formation and development of the fetus. No vitamins during a diet will correct this situation. Moreover, in addition to a full diet, the expectant mother must take special vitamin complexes. The only exception is a therapeutic diet, which helps reduce toxicosis and nausea, which very often occurs in pregnant women.
- Women during lactation - following a diet and taking vitamins will not worsen the taste of milk for the baby, but poor nutrition will lead to the removal of microelements and vitamins from the mother's body.
- Children and teenagers are another category that is contraindicated to diet. Every child should eat well and take a number of vitamins that will protect the body from the negative effects of hormonal development. The exception is therapeutic diets prescribed by a doctor.
- Elderly people – pensioners are prohibited from going on diets to lose weight. This is explained by the fact that any diet, even one that is accompanied by a vitamin complex, is a burden on a “worn out” body.
- People with diabetes and any chronic diseases - it is necessary to understand that any diet can become life-threatening and cause an exacerbation of diseases or provoke new ones. Therefore, before losing weight with the help of a diet, it is necessary to consult with your doctor.
If you decide to go on a diet, then you need to follow a few simple rules:
- When limiting yourself in food and taking vitamins during a diet, it is forbidden to limit fluid intake. This is due to the fact that a lack of fluid can lead to dehydration, which is very dangerous, as it causes severe intoxication.
- It is not recommended to go on diets in spring. During this period, the body already suffers from vitamin deficiency, and the additional load, that is, the diet, can lead to serious diseases.
- It is forbidden to stick to diets that promise a large weight loss in a short period of time. Since even vitamin complexes taken during this period will not save you from the harmful consequences for the body.

Vitamins Alphabet in Diet
Vitamins Alphabet during a diet is a complex of vitamins that supply the body with all the necessary microelements and nutrients necessary for proper functioning. Many people mistakenly believe that mono-diets, fruit, vegetable, buckwheat diets saturate the body with all the necessary minerals and vitamins. But this is not true, since even the most balanced diet at first glance does not cover the body's daily need for vitamins and minerals. The main disadvantage of any mono-diet is poor absorption of vitamins from food. Therefore, you cannot do without vitamins during a diet.
Vitamins Alphabet Diet are distributed among three tablets of different colors. This is necessary so that the patient knows which tablet to take at what time. In addition, consistent intake of vitamins ensures the full functioning of the body and ensures normal well-being, without causing side effects.

Vitamins for the Dukan Diet
Vitamins in the Dukan diet help the body not to feel a lack of nutrients, minerals and vitamins due to dietary restrictions. Any diet, like the Dukan diet, is stress for the body, which causes a decrease in the functions of the immune system, muscle tone and carbohydrate intake. Any vitamin complex must be taken from the first days of the diet.
Since the Dukan diet consists of three phases, each of which involves restrictions in certain products, it is necessary to select vitamin preparations with a full range of useful components. When following the Dukan diet, you can take vitamins Alphabet, Multi-tabs and others.
During the diet, it is strictly forbidden to take dietary supplements and weight loss pills. Since this can lead to disruption of the normal processes of fat breakdown.

Vitamins for a protein diet
Vitamins are extremely necessary in a protein diet, as the body experiences a significant deficiency of nutritional components. The diet is based on the fact that carbohydrates, proteins or fats are excluded from the diet, which does not have a very good effect on the general well-being and condition of the body.
- The protein diet is based on products with a high protein content: fish, cottage cheese, cheese, chicken. The protein diet is considered low-carbohydrate and when following this diet, the body feels a lack of ascorbic acid, that is, vitamin C and fiber. To maintain the normal functioning of the body, it is necessary to take bran and multivitamin complexes rich in vitamin C and fiber.
- When following a low-protein, i.e. vegetarian diet, it is also necessary to take vitamins. This type of diet is based on eating fruits and vegetables, i.e. plant foods. In this case, the body feels a lack of vitamins A, B, E, which are found in food of animal origin. Therefore, it is recommended to take vitamin complexes rich in vitamins B, A and E.
- If you stick to a low-fat diet, it will negatively affect your health. To support your body and immune system, it is recommended to take fish oil capsules and vitamins that contain this ingredient.
When taking any vitamin complex, it is necessary to follow the instructions for the drug, strictly observe the indicated dosage and duration of administration. If the diet involves a week of limited nutrition, then vitamins should be taken for 2-3 weeks.
Vitamins after diet
Vitamins after a diet are needed in the same way as during a diet. Vitamins after a diet help restore the normal functioning of the body and improve the protective functions of the immune system. Today, the pharmaceutical market offers many vitamin complexes and multivitamin preparations that contain all the vitamins and minerals necessary for the full functioning of the body.
After the diet, it is recommended to take vitamins Alphabet, Duovit, Multi-tabs, Vitamult and others. These vitamin complexes protect against breakdowns during the diet, blocking the feeling of hunger and supplying the body with energy. The drugs saturate the body with all the substances, minerals and vitamins necessary for full life, improve metabolic processes and speed up metabolism, which has a positive effect on the results of dieting.
Reviews of vitamins for diet
Numerous positive reviews of vitamins during a diet confirm the need to take vitamin complexes with a limited diet. Vitamins must be taken both before the diet, preparing the body for a very specific diet, and during and after the diet. Such full care of the body, even with a limited intake of nutrients from food, ensures a healthy appearance, good health and positive results of any diet.
Vitamins must be taken during a diet, as this is the first and main rule of good health and well-being. It is recommended to choose a suitable vitamin complex after consulting a nutritionist, focusing on the characteristics of the diet and body. Do not forget that vitamins must be taken intermittently. Vitamins improve the results of any diet and protect against breakdowns during a period of limited nutrition.
