A vitamin is a molecule that is literally called an essential micronutrient, which the metabolism needs in small quantities to function properly. Essential nutrients can either not be synthesized at all in the organism or cannot be synthesized in sufficient quantities.

Turkey Medicals International Co-Ordinator, “For this reason, it must be taken through nutrition. So, where are vitamins in our lives? Pharmacist department from Samsun MedicalPark Hospital Turkey gave more detailed information.” she shares.

Q- What is the importance of vitamins for our body?

Vitamins and minerals are the most necessary components for living a healthy life. From the transport of oxygen to the cells to the formation of the basis of the nervous-muscle-bone system, from the continuity of vision to the strengthening of blood production and immune system, from the conversion of macronutrients into energy to the formation of skin, hair, nail tissue, from the cleansing of the body from toxins, in short, it has many vital roles in protecting against chronic diseases. No minerals or vitamins other than vitamin D can be synthesized in our body, so we need external support.

Q- Aren’t we getting enough vitamins from food?

World Health Organization recommends consuming 5-9 servings of vegetables or fruits daily so that we can get the vitamins and minerals we need from foods. However, the vegetable-fruit consumption rate in Turkey is limited to 1.5 servings per day… Moreover, we do not eat enough and regularly, we include processed foods in our lives. As a result, we cannot afford the vitamins and minerals we need daily. For this reason, we definitely need to get support from multi-vitamins, which contain vitamins, minerals, antioxidants, as well as amino acids decombustly.

Q- How will we know the best vitamin supplement when there are hundreds of different vitamin options on the market?

Most of us usually take vitamins with hearsay information, at the suggestion of our neighbor, friend, because we do not know this. Sometimes that’s why we can use a vitamin that won’t fully meet our needs at the wrong times and doses. However, when taking vitamin and mineral support, instead of choosing a single and high dose, it is more correct to use vitamins prepared in appropriate doses for age and gender on a daily basis. Just as if you don’t consume only spinach or only meat or only yogurt for a day, you include mixed foods on your table; it is also important that the supplements you use contain mixed and multiple ingredients according to the needs. In addition, you should prefer products of reliable brands that do not contain preservatives, gluten, yeast, contain doses specific to your gender and needs.

Q- At what age do vitamins stand out?

  • During childhood and adolescence, it is necessary to consume sufficient amounts of A, B, C, D, zinc, magnesium, iodine, copper, EPA and DHA.
  • At the same time, it is important to consume an adequate amount of calcium during this period when bone development takes place. Insufficient calcium absorption during this period increases the risk of developing systemic bone diseases such as osteoporosis, which can be seen at an advanced age.
  • Blood loss experienced during menstruation and diets can lead to anemia in women in their 20s. To prevent anemia, we should use micronutrients such as iron, vitamin B6, B12 and C, folic acid, zinc, copper.
  • Vitamin D deficiency in our country is up to 99 percent, so it is necessary to meet the daily vitamin D requirement at any age.
  • During this period, which steps into pregnancy with the age of 30, folic acid for a healthy pregnancy, calcium, vitamin D, zinc and magnesium needs to be met to support the lost bone calcium reserves.
  • Antioxidant use is important for all ages, but especially antioxidants such as vitamin C and E, selenium, acaiberry should be used to prevent accumulated free radical damage in the 40s. Antioxidants support the protection of many systems such as the immune system, skin health, eye health, bone health.
  • Minerals such as magnesium and chromium, which help to prevent chronic diseases such as cardiovascular health, cholesterol and diabetes; magnesium is essential for muscle health.
  • During these periods when bone destruction increases, vitamins and minerals that support bone construction, such as calcium, vitamin D, zinc and magnesium, should be used.
  • You should continue to use vitamins and minerals used in your 40s, and also get support from vitamin B for mental health.
  • Just as our needs change at different ages, our vitamin and mineral requirements may change at different periods. Cranberry should be used to protect against urinary tract infections during the holiday periods, zinc, biotin, selenium, B vitamins and vitamin C should be used to reduce the damage caused by the sun to the skin, hair and nails.
  • Before, during and after menopause, special nutrients such as soy isoflavones will be useful to prevent bone and heart disorders that may be caused by decreased estrogen.
  • Special nutrients such as L-carnitine and magnesium can be preferred to support muscle health in men, primrose and borage oil, which are rich sources of GL muscle to reduce PMS pain in women.
  • Those who stay in front of the screen for a long time can benefit from supplements such as lutein, zinc, bilberry extract, selenium, EPA and DHA to support eye health.
  • Students, employees or those of advanced age who want to support mental health and improve their emotional state can use micronutrients such as phosphotidylserine, phosphotidylcholine, l-glutamine, iodine, CoQ10, 5-HTP, glutathione and B vitamins.

Q- What are the situations in which vitamins are harmful?

Using vitamins that our body does not need or overdoing it in vitamin use can have many serious side effects such as kidney failure, fatty liver, vascular blockage, overwork of certain glands and therefore hormone imbalance. Especially vitamin – mineral products with a single content are usually formulated in high doses, since they also have a place in treatment. I recommend that single high-dose ingredients and fat-soluble vitamins should definitely be used under the supervision of a doctor in Istanbul and Antalya clinics.

If you do not have any chronic conditions and a special disease, you can also use a multi-vitamin prepared for your gender, age, needs without a Turkish doctor’s recommendation. However, since there are not many products with these criteria, you should pay attention when choosing a product. Some multi-vitamins contain high doses of fat-accumulating vitamins such as A, D, E and K. Using such products without the supervision of a health professional can damage your body. Therefore, the answer to this question depends on the person and the product.

Q- Can you tell us about the importance of vitamin use during osteoporosis, especially for us women?

The period in which bone production increases the most is childhood and adolescence, and the period in which it breaks down the fastest is pregnancy, breastfeeding and menopause in women. To reduce the risk of osteoporosis, we should protect our bone health, especially during these periods, and use a calcium supplement. To support bone health, calcium should be used in combination with micronutrients such as vitamin D, zinc, copper and selenium, which also play a role in calcium absorption and mobilization, and are involved in various steps in bone construction, to prevent oxidative damage to bones.

In addition to the use of food supplements to prevent osteoporosis, physical activity should be increased, stairs should be preferred instead of elevators, regular exercise programs should be prepared in consultation with a specialist. Milk and dairy products should be consumed in the daily diet, alcohol and smoking should be avoided, and regular health checks should be carried out.
