Vitamins (macronutrients) are vital nutrients that are essential for maintaining the health of both the average person and an athlete. They play a key role in the biochemical and physiological processes of the body, including strengthening the immune system, recovery after training, and regulating metabolism.
Regarding the consequences of deficiency and excess, an imbalance of vitamins, whether insufficient or excessive, can lead to negative consequences. Symptoms of deficiency include increased fatigue, nervous breakdowns, irritability, and suppression of the body’s defenses. In turn, uncontrolled consumption of vitamins in large quantities can also be harmful to health.
- The daily requirement for vitamins varies depending on the individual characteristics of a person, including the level of physical activity. Athletes, especially bodybuilders, require more vitamins to maintain high loads and restore muscle tissue. For example, B vitamins play an important role in energy metabolism, which makes them especially important for athletes. We will analyze the daily requirement dosage a little further.
Vitamins participate in various processes: from growth and restoration of muscle tissue to strengthening the immune system. A lack of vitamins can lead to decreased performance and overtraining. On the contrary, adequate vitamin intake contributes to the optimal functioning of the body and its defense mechanisms.
It is important to maintain a balance and not exceed the recommended dosages. Determining individual vitamin needs requires consultation with a specialist and taking into account lifestyle. Vitamin balance should be maintained in a comprehensive manner, through a balanced diet and a healthy lifestyle.

Vitamin C
Strength training, including bodybuilding, significantly increases the body’s need for micronutrients. This is especially true for professional athletes, who should increase the dosages indicated in the general recommendations several times…
The effects of micronutrient deficiency: an example of vitamin C
Let’s consider, for example, a deficiency of ascorbic acid (vitamin C). Its deficiency leads to bleeding, decreased immune protection against infections, joint pain and disturbances in the body’s biochemical processes, as well as to a stop in muscle growth.
- Recommended daily intake: The general recommended daily intake of ascorbic acid is 70 mg. However, it is important to understand that the need may vary depending on individual characteristics, lifestyle and level of physical activity. Athletes, especially those involved in strength sports, should increase this dosage after consulting with a specialist.
Precautions: Blood Clots
It is also important to note that taking ascorbic acid may be dangerous for people prone to blood clots. High doses may provoke blood clots. This emphasizes the need to consult a doctor before taking any supplements, including vitamin C, and the importance of a balanced and varied diet.

B Vitamins
B vitamins play a key role in various aspects of health, affecting energy metabolism, the nervous system, skin, hair and much more. Deficiency of each of them can lead to specific problems. Let’s look at the consequences of deficiency of each of them and the recommended daily intake.
Thiamine (Vitamin B1) | Deficiency of this substance can manifest itself in the form of general weakness, low blood pressure, anorexia, irritability, depression, insomnia, constipation and decreased immunity. The recommended daily intake is 1.7 mg. |
Riboflavin (Vitamin B2) | Deficiency of riboflavin often manifests itself in the form of cracks in the corners of the mouth, dull and falling hair, dandruff, photophobia, vision problems, wrinkles above the upper lip, slow wound healing, anemia and weakened immunity. The recommended daily intake is 2 mg. |
Niacin (Vitamin B3 or PP) | Niacin deficiency can lead to drowsiness, depression, depression, irritability, insomnia, tooth decay, bad breath and a tendency to constipation. The daily requirement is 20 mg. |
Pantothenic acid (Vitamin B5) | A deficiency of this substance can cause skin diseases, the appearance of white spots on the skin, premature graying of hair and discoloration of the iris. The recommended daily intake is 5 mg. |
Pyridoxine (Vitamin B6) | Pyridoxine deficiency manifests itself in the form of tremors in the hands, memory loss, nervous tics, acne and obesity. The daily requirement is 2 mg. |
Inositol (Vitamin B8) | A lack of inositol can lead to premature graying and hair loss. The recommended daily intake is 500 mg. |
Folic acid (Vitamin B9) | Folic acid deficiency is especially dangerous during pregnancy, as it can lead to intrauterine growth retardation, including damage to the nervous system. Other symptoms of deficiency include weakness, irritability, chronic fatigue syndrome, depression, anemia, and deterioration of the stomach. The daily requirement is 400 mcg. |
Cyanocobalamin (Vitamin B12) | A lack of cyanocobalamin leads to anemia with damage to blood cells. The recommended daily requirement is 3 mcg. |
Interrelationships and general recommendations:
It is important to remember that B vitamins work in combination, and their deficiency can affect the absorption and effectiveness of each other. A balanced diet rich in a variety of foods is the best way to get all the necessary B vitamins. If symptoms of deficiency occur, it is recommended to consult a specialist for diagnosis and selection of an individual supplement regimen.
Vitamin A
Retinol, also known as vitamin A, plays an important role in maintaining healthy skin, hair, nails and vision. Its deficiency can lead to a number of unpleasant and even serious consequences that affect the overall health of the body.
Consequences of retinol deficiency:
Vitamin A deficiency can manifest itself in various forms:
- On the skin. It becomes dry, flaky, cracked and acquires an unhealthy grayish tint.
- On the hair. Hair becomes brittle, splits and loses its healthy shine.
- On the nails. Nails become brittle, grow slowly and can become deformed.
- On vision. One of the most characteristic symptoms of vitamin A deficiency is deterioration of vision in the dark, the so-called «night blindness».
Recommended daily intake:
The recommended daily intake of vitamin A is 1 mg. However, it is important to consider that needs may vary depending on age, gender and overall health.
Vitamin A, like other micronutrients, works closely with other vitamins and minerals. A balanced diet rich in a variety of foods is the best way to provide the body with the necessary amount of vitamin A. If symptoms of deficiency occur, it is recommended to consult a specialist for diagnosis and the appointment of an individual regimen for taking supplements.
This is interesting! It is worth noting that vitamin A is a fat-soluble vitamin, so for its absorption in the body, the presence of fats is necessary. This should be taken into account when preparing a diet.

The Importance of Vitamins D, K, E, and H for the Body
Vitamins D, K, E, and H play an important role in various processes in the body. Their deficiency can lead to serious problems. Let’s take a closer look at the consequences of their deficiency and the recommended daily intake.
- Cholecalciferol (Vitamin D):
- A deficiency of this vitamin is especially dangerous in childhood, as it can lead to rickets, curvature of the bones of the legs, chest, and skull. In adults, a deficiency of vitamin D manifests itself in the form of brittle and fragile bones. The recommended daily intake is 5 mcg.
- Additional information: Vitamin D is synthesized in the skin under the influence of sunlight, so it is important to spend enough time in the sun.
- Phylloquinone (Vitamin K):
- A deficiency of vitamin K can manifest itself in the form of frequent nosebleeds. The recommended daily intake is 120 mg. Vitamin K plays an important role in blood clotting, and its deficiency can lead to bleeding problems.
