Why do older people especially need vitamins
In old age, the concentration of vitamins in the blood may be two to three times lower than normal. Lack of vitamins B1 and B2 is observed in 40% of the population of our country, who crossed the 50-year age limit. 10-30% of pensioners suffer from B6 deficiency. 60% of people over 50 years of age lack ascorbic acid, 40% lack retinol (A), 20% lack vitamin B12. The most unfortunate situation is that of vitamin E. According to numerous studies, about 80% of pensioners suffer from vitamin E deficiency. Vitamin deficiency in the elderly and the elderly is explained by the fact that with age, bioactive substances are less absorbed by the intestinal walls. This phenomenon is attributed by physicians to the physiological norm, which accompanies the process of aging.
What significance do vitamins have for the body of people over 50-60 years of age?
An aging body needs to be provided with a sufficient supply of vitamins. The most important of these vitamins:
- D. It is necessary to assimilate calcium, which in older people is washed from the bones, making them fragile and increasing the risk of fractures. Also vitamin D helps the body of an elderly person to resist colds infections.
- B2. With a lack of this vitamin, the visual and nervous system is particularly affected. In addition, the body’s resistance to infections is reduced.
- B12. Deficiency of this substance may lead to irreversible damage to the brain and nervous system. There is evidence that it is B12 deficiency that can cause mental disorders, depression and senile dementia at the age of 70-80 years. Regular intake of this vitamin is useful for memory, which affects most pensioners over 70 years of age.
- B6. Helps to avoid immune problems typical for elderly people. This substance is involved in the production of lymphocytes – cells of the body that provide the production of antibodies.
- PP. Helps maintain the gastrointestinal tract, as well as the function of the central nervous system, which is often impaired in old age. Niacin deficiency in elderly people is manifested by irritability, rapid fatigue, insomnia.
- K. Reduces the risk of nasal bleeding and hematoma. Both in older people may be associated with vascular fragility.
What role do antioxidant vitamins play in the elderly organism?
Antioxidant substances are essential to the body to fight oxidative processes that are activated in old age. Free radicals trigger such destructive reactions. They are unstable compounds that accelerate the aging process and destroy cell membranes. Oxidative stress can lead to serious diseases such as cancer, cataracts, depression, dementia. Antioxidant vitamins include A (beta-carotene), C and E. At the age of over 50 they should be used according to indications, and people 70-80 years – on a regular basis. It is necessary to consult with a doctor beforehand.
Each of the antioxidants acts in its own way:
- A (beta-carotene). It helps to preserve the integral structure of cells, neutralizing the strongest oxidant – atomic oxygen. Beta-carotene also helps to strengthen the vascular walls and helps fight diseases of the circulatory system. In particular, there is evidence that people with a vitamin A deficiency are more likely to suffer from strokes. Therefore, specialists recommend retired people to take it in a higher dose, as prescribed by a doctor.
- E (tocopherols). This is the most powerful antioxidant, which is included in almost all vitamin complexes for elderly people. It inhibits the aging process, protects the brain from damage. It reduces the risk of thrombosis, increases the body’s endurance.
- C (ascorbic acid). Vitamin is necessary for the normal operation of the immune system, helps the body to resist viruses and bacteria, strengthens the heart and blood vessels. Regular replenishment of ascorbic acid in the body is one of the measures to prevent atherosclerosis.
To get the maximum benefit from substances with antioxidant properties, they should not be taken in isolation, but as a whole.
What vitamins do women need after 50 years of age?
With the onset of menopause, women are at risk of developing osteoporosis – bone fragility. To prevent fractures, it is necessary to take calcium in combination with vitamin D. This helps prevent such a severe consequence of osteoporosis as a femoral neck fracture. In addition, older women need to ensure an additional intake of B vitamins, which are worse absorbed after 50-60 years. At this age, the doctor may also prescribe additional intake of retinol (A), ascorbic acid (C), tocopherol (E) and calciferol (D). This is necessary for the prevention of cardiac, vascular, and cancer diseases.
