Are dietary supplements safe for women’s health: a deep analysis of the composition, risks and advantages
I. Definition of dietary supplements and their regulation
Biologically active food additives (dietary supplements) are concentrated sources of nutrients (vitamins, minerals, amino acids, fatty acids, probiotics, prebiotics, etc.) intended to supplement the diet. They are produced in various forms, including tablets, capsules, powders, liquids and gels. It is important to understand that dietary supplements are not drugs and are not intended for the treatment of diseases.
I.1. Differences from drugs
The key difference between dietary supplements and drugs is in the process of regulating and approval. Medicines are subjected to strict clinical trials to prove their effectiveness and safety for specific diseases. These tests include phases I, II and III, during which pharmacokinetics, pharmacodynamics, side effects and effectiveness of the drug are evaluated. The results of these tests are carefully analyzed by regulatory authorities (for example, FDA in the USA, EMA in Europe) before the drug is approved for sale.
Dietary supplements, on the contrary, do not go through the same strict process of approval. Dad manufacturers are not required to prove their effectiveness in the treatment of any diseases. Instead, they are responsible for ensuring the safety of their products and so that the labels do not contain false or misleading statements. Regulatory authorities, as a rule, are conducted after the dietary supplements have been on sale, and may take measures if violations are detected, such as inappropriate labeling, pollution or false health benefits.
I.2. Bad regulation in different countries
The regulation of dietary supplements varies significantly in different countries. In the United States, for example, dietary supplements are regulated as food, and not as medicines, in accordance with the Law on Food additives, healthcare and education (DSHEA) of 1994. This law limits the powers of the FDA in relation to the regulation of dietary supplements, which makes it difficult to control their quality and safety.
In Europe, the regulation of dietary supplements is carried out at the level of the European Union (EU) and national member states. The European food safety department (EFSA) evaluates the safety of food ingredients, including those used in dietary supplements. National authorities in EU member countries are responsible for monitoring compliance with food and dietary supplements legislation.
In Russia, the regulation of dietary supplements is carried out by the Federal Service for Supervision of Consumer Rights Protection and Human Welfare (Rospotrebnadzor). Bades are subject to state registration, during which their safety and compliance with sanitary standards are evaluated.
II. The most popular dietary supplements for women and their alleged advantages
Women often turn to dietary supplements to solve various health problems associated with the menstrual cycle, pregnancy, menopause, the condition of the skin, hair and nails, as well as general well -being.
II.1. Vitamins and minerals
- Vitamin D: It is important for the health of bones, the immune system and mood. Vitamin D deficiency is widespread, especially in regions with limited sunlight. Women during menopause and postmenopause are especially at risk of vitamin D and osteoporosis deficiency.
- Calcium: It is necessary for the health of bones and teeth, as well as for the normal functioning of muscles and nerves. Women need enough calcium throughout life, especially during pregnancy, breastfeeding and menopause.
- Iron: It is important for transporting oxygen in the blood. Women are more prone to iron deficiency due to menstrual bleeding and pregnancy. Iron deficiency can lead to anemia, fatigue and weakness.
- Folic acid (vitamin B9): It is necessary for dividing cells and the development of the fetus during pregnancy. Take of folic acid is recommended for all women planning pregnancy, as well as in the first trimester of pregnancy to reduce the risk of defects in the nervous tube in the fetus.
- B vitamins B: They play an important role in the energy exchange, the work of the nervous system and the formation of red blood cells. Vitamin B12 is especially important for vegetarians and vegans, as it is mainly found in animal products.
II.2. Herbal additives
- Cranberry: Used to prevent urinary tract infections (IMP). Cranberry contains proanthocyanidines, which can prevent the attachment of bacteria to the walls of the bladder.
- Soybeans and isoflavoni: They contain compounds similar to estrogen, and can help alleviate the symptoms of menopause, such as tides and night sweating. However, studies of the effectiveness of soy and isoflavon to alleviate the symptoms of menopause give conflicting results.
- Black Kokhosh: Herbal supplement used to relieve symptoms of menopause. The mechanism of action of the Black Kochosha is not completely understandable, but it is assumed that it can affect the level of estrogen or other neurotransmitters in the brain.
- Dudnik Chinese (Dong Kuai): It is traditionally used in Chinese medicine to treat female diseases, such as irregular menstruation, premenstrual syndrome (PMS) and symptoms of menopause. However, the scientific evidence of the effectiveness of the Dudnik of Chinese is not enough for these purposes.
- Evening primrose oil: Contains gamma-linolenic acid (GLA), which is omega-6 fatty acid. Evening primrose oil is used to alleviate the symptoms of PMS, such as chest pain, irritability and bloating.
II.3. Other dietary supplements
- Probiotics: They contain live microorganisms that can improve intestinal health. Probiotics can be useful for women with vaginal infections such as bacterial vaginosis and candidiasis.
- Omega-3 fatty acids: Important to the health of the heart, brain and joints. Omega-3 fatty acids can also help reduce inflammation and relieve PMS symptoms.
- Collagen: Protein, which is the main component of the skin, hair, nails and joints. Collagen additives can help improve skin elasticity, reduce wrinkles and strengthen joints.
- Hyaluronic acid: A substance that is naturally contained in the skin and joints. Hyaluronic acid has the ability to retain water, which helps to moisturize the skin and lubricate the joints.
III. Risks and side effects of dietary supplements
Despite the fact that dietary supplements are often perceived as “natural” and, therefore, safe, they can represent certain health risks.
III.1. Lack of strict quality control
One of the main risks associated with dietary supplements is the lack of strict quality control. Unlike drugs, dietary supplements do not undergo thorough clinical trials before entering sale. This means that the composition and dosage of ingredients in dietary supplements can vary from party to party and from the manufacturer to the manufacturer. Some dietary supplements may contain ingredients not indicated on the label, or contain pollutants, such as heavy metals, pesticides or bacteria.
III.2. Interaction with drugs
Bades can interact with drugs by changing their effectiveness or increasing the risk of side effects. For example, St. John’s wort can reduce the effectiveness of some antidepressants, contraceptives and drugs for HIV treatment. Vitamin K can reduce the effectiveness of anticoagulants such as warfarin. It is important to inform the doctor about all the dietary supplements that you accept in order to avoid potentially dangerous interactions.
III.3. Side effects
Some dietary supplements can cause side effects, especially when taking high doses or in combination with other additives or drugs. For example, taking high doses of vitamin D can lead to nausea, vomiting, weakness and kidney problems. Taking large doses of iron can cause constipation, nausea and abdominal pain. Herbal supplements, such as black Kokhosh and Dudnik Chinese, can cause side effects, such as stomach disorder, headache and dizziness.
III.4. Risks for certain groups of women
Some groups of women should be especially careful when receiving dietary supplements.
- Pregnant and lactating women: Many dietary supplements were not properly investigated for their safety during pregnancy and breastfeeding. Some dietary supplements can be harmful to the fetus or baby. It is important to consult a doctor before taking any dietary supplements during pregnancy or breastfeeding.
- Women with chronic diseases: Women with chronic diseases, such as liver, kidneys, heart or diabetes, should be especially careful when taking dietary supplements, as they can interact with the medicines that they take, or aggravate their condition.
- Women preparing for the operation: Some dietary supplements, such as vitamin E, garlic, ginger and ginkgo bilobe, can dilute blood and increase the risk of bleeding during and after surgery. It is important to stop taking these dietary supplements at least two weeks before surgery.
III.5. False statements of health benefits
Bades sometimes make false or misleading statements about the health benefits of their products. They may argue that their dietary supplements can cure or prevent diseases, although there is no scientific evidence confirming these statements. It is important to be skeptical of such statements and rely on verified information from reliable sources.
IV. How to choose safe and effective dietary supplements
When choosing dietary supplements, it is important to observe caution and be guided by the following recommendations:
IV.1. Consult a doctor
Before you start taking any dietary supplements, especially if you have any diseases or take medicines, be sure to consult a doctor or other qualified health specialist. The doctor can evaluate your nutrient needs and recommend suitable dietary supplements, taking into account your health status, the medicines that you take, and possible risks and side effects.
IV.2. Choose products from reliable manufacturers
Choose dietary supplements from well -known and reliable manufacturers who adhere to high quality standards and undergo independent testing of their products. Look for products certified by third -party organizations such as NSF International, USP or Consumerlab.com. These organizations carry out independent testing of dietary supplements to verify their composition, purity and compliance with the declared characteristics.
IV.3. Read the labels carefully
Carefully read the bades to learn about the composition, dosage, warnings and possible side effects. Make sure that the product does not contain the ingredients that you are allergic or intolerance to. Pay attention to warnings about interaction with medicines or other contraindications.
IV.4. Avoid high doses
Do not take dietary supplements in doses exceeding the label recommended on the label or recommended by the doctor. Taking high doses of some vitamins and minerals can be harmful to health.
IV.5. Inform the doctor about the admission of dietary supplements
Tell your doctor about all the dietary supplements that you take, especially before the operation or when prescribing new drugs. This will help to avoid potentially dangerous interactions.
V. Alternatives to receive dietary supplements: a balanced diet and a healthy lifestyle
Instead of relying on dietary supplements, try to receive the necessary nutrients from a balanced diet and a healthy lifestyle.
V.1. Balanced diet
A balanced diet, rich in fruits, vegetables, whole cereals, low -fat protein and healthy fats, provides the body with all the necessary vitamins, minerals and other nutrients. Try to include a variety of foods from all food groups in your diet to ensure the receipt of all the necessary nutrients.
V.2. A healthy lifestyle
A healthy lifestyle, including regular physical exercises, sufficient sleep, stress management and abandoning smoking and alcohol abuse, is also important for maintaining female health. Physical exercises help strengthen the bones, improve mood and reduce the risk of chronic diseases. A sufficient sleep is necessary to restore the body and maintain the immune system. Stress control helps to reduce the level of cortisol, stress hormone, which can negatively affect health.
VI. The role of dietary supplements in specific situations
In some cases, dietary supplements can be useful, especially if you have a nutrient deficiency or certain health conditions. However, it is important to use dietary supplements with caution and under the control of a doctor.
VI.1. Nutrient deficiency
If you have a nutrient deficiency, confirmed by blood test, the doctor may recommend taking dietary supplements to replenish the deficiency. For example, if you have a deficiency of vitamin D, the doctor may recommend taking vitamin D in the form of an additive.
VI.2. Pregnancy and breastfeeding
During pregnancy and breastfeeding, the need for certain nutrients, such as folic acid, iron and calcium, increases. The doctor may recommend taking dietary supplements to ensure sufficient receipt of these nutrients.
VI.3. Menopause
Some women may experience unpleasant symptoms during menopause, such as tides, night sweating and mood swings. Some dietary supplements, such as soy and black hot, can help alleviate these symptoms. However, it is important to consult a doctor before taking these dietary supplements, since they can have side effects and interact with medicines.
VII. Future research and development of dietary supplements
Studies in the field of dietary supplements continue, and in the future new and more effective additives for women’s health may appear. It is important to monitor new research and rely on proven information from reliable sources. The development of technology can also lead to the emergence of better and safe dietary supplements.
