Bades: myths and reality about harm to health

I. What are Dietary Supplements (БАДы)? A Precise Definition

Dietary supplements, known as БАДы (биологически активные добавки) in Russian, are products intended to supplement the diet. This definition, however, is surprisingly broad and often misinterpreted. To understand the potential benefits and risks, a precise understanding of what constitutes a dietary supplement is crucial.

A. Defining Characteristics:

1. Intended Use: The primary purpose of a dietary supplement is to supplement the diet. This means it’s meant to provide nutrients that may be missing or not consumed in sufficient quantities through regular food intake. They are not intended to be a substitute for a balanced diet or a treatment for any disease.

2. Form: Dietary supplements come in various forms, including:

   • Pills/Tablets: Solid dosage forms containing compressed or encapsulated ingredients. Examples include multivitamins, calcium supplements, and iron supplements.
   • Capsules: Solid dosage forms where ingredients are enclosed in a hard or soft gelatin shell. These can contain powders, liquids, or oils. Examples include fish oil capsules, vitamin E capsules, and herbal extracts.
   • Powders: Dry, particulate forms that can be mixed with liquids for consumption. Examples include protein powders, creatine, and some herbal supplements.
   • Liquids: Solutions, suspensions, or emulsions that are taken orally. Examples include liquid vitamin D, herbal tinctures, and some mineral supplements.
   • Softgels: A variation of capsules, typically containing oils or liquids, encased in a soft, pliable gelatin shell. Often used for fat-soluble vitamins and omega-3 fatty acids.
   • Gummies: Chewable, fruit-flavored forms that are popular, especially for children’s vitamins. However, they may contain added sugars and artificial colors.

3. Ingredients: Dietary supplements contain one or more dietary ingredients. These can include:

   • Vitamins: Essential organic compounds needed in small amounts for various bodily functions. Examples include Vitamin A, Vitamin C, Vitamin D, and B vitamins.
   • Minerals: Inorganic substances needed for various bodily functions. Examples include calcium, iron, zinc, magnesium, and potassium.
   • Herbs or Botanicals: Plant-derived substances used for their purported medicinal or therapeutic properties. Examples include St. John’s Wort, Ginkgo Biloba, and Echinacea.
   • Amino Acids: The building blocks of proteins, essential for growth, repair, and various metabolic processes. Examples include creatine, glutamine, and branched-chain amino acids (BCAAs).
   • Enzymes: Proteins that catalyze biochemical reactions in the body. Examples include digestive enzymes like amylase, lipase, and protease.
   • Other Dietary Substances: This is a broad category that can include substances like probiotics (beneficial bacteria), prebiotics (substances that promote the growth of beneficial bacteria), omega-3 fatty acids, and antioxidants.

4. Labeling: Dietary supplements must be labeled as such and include specific information:

   • Statement of Identity: Clearly identifies the product as a dietary supplement.
   • Net Quantity of Contents: Indicates the amount of product in the container (e.g., number of capsules, weight of powder, volume of liquid).
   • Directions for Use: Provides instructions on how to take the supplement.
   • Supplement Facts Panel: Lists the dietary ingredients, the amount per serving, and the percent Daily Value (DV) for nutrients that have an established DV.
   • Ingredient List: Lists all ingredients in descending order of predominance.
   • Name and Location of Manufacturer, Packer, or Distributor: Identifies the responsible party.
   • Disclaimers: Must include the statement: “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.” This disclaimer is crucial because it highlights that dietary supplements are not drugs.

B. Distinguishing from Pharmaceuticals (Лекарства): A Critical Difference

The fundamental difference between dietary supplements and pharmaceuticals (лекарства) lies in their regulatory pathways and intended use.

1. Regulatory Oversight: Pharmaceuticals undergo rigorous testing and approval processes by regulatory agencies (like the FDA in the US or the EMA in Europe) before they can be marketed. This includes preclinical studies (in vitro and in vivo) to assess safety and efficacy, followed by multiple phases of clinical trials (Phase I, II, and III) in human subjects. The results of these trials are meticulously reviewed before a drug is approved for sale.

   Dietary supplements, on the other hand, are regulated differently. In many countries, including the US, they are regulated as food products, not drugs. This means they do not require pre-market approval. The manufacturer is responsible for ensuring the safety of the product, but the regulatory agency (like the FDA) does not evaluate the supplement’s safety or efficacy before it is sold. The agency can take action if a supplement is found to be unsafe or mislabeled after it is already on the market. This lack of pre-market scrutiny is a significant point of concern regarding the safety and quality of dietary supplements.

2. Claims: Pharmaceuticals can make specific claims about their ability to treat, cure, prevent, or mitigate diseases. These claims are supported by the evidence from clinical trials. For example, a drug might be approved to treat hypertension or lower cholesterol.

   Dietary supplements, as mentioned in the disclaimer, are not allowed to make such claims. They can only make structure/function claimswhich describe the role of a nutrient or dietary ingredient in maintaining the normal structure or function of the body. For example, a calcium supplement can claim that it supports bone health, but it cannot claim to treat osteoporosis.

3. Manufacturing Standards: Pharmaceuticals are subject to strict Good Manufacturing Practices (GMPs) that are enforced by regulatory agencies. These GMPs cover all aspects of drug production, including ingredient sourcing, manufacturing processes, quality control, and labeling. The goal is to ensure that drugs are consistently produced according to quality standards.

   Dietary supplements are also subject to GMPs, but these standards are often less stringent and may not be as rigorously enforced as those for pharmaceuticals. This can lead to inconsistencies in the quality, purity, and potency of dietary supplements.

C. Common Types of БАДы (Dietary Supplements) in Russia:

The Russian market for dietary supplements is vast and diverse. Here are some of the most common types:

1. Multivitamins and Minerals (multivitamins and minerals): These are among the most widely used dietary supplements, designed to provide a broad range of essential vitamins and minerals. They are often marketed to address perceived nutritional deficiencies or to support overall health and well-being. Common examples include Centrum, Supradin, and Complivit.

2. Omega-3 Fatty Acids (omega-3 fatty acids): Derived from fish oil or algae, these supplements are popular for their purported cardiovascular benefits, anti-inflammatory properties, and support for brain health. Popular brands include Solgar, Nordic Naturals, and отечественные производители (domestic producers).

3. Probiotics (probiotics): These supplements contain live microorganisms (beneficial bacteria) that are intended to improve gut health and support the immune system. Common strains include Lactobacillus and Bifidobacterium. Examples include Linex, Bifiform, and Acipol.

4. Calcium and Vitamin D (calcium and vitamin D): Often taken together, these supplements are crucial for bone health and preventing osteoporosis. They are particularly important for women after menopause and older adults. Common brands include Calcium-D3 Nycomed and Vitrum Calcium + Vitamin D3.

5. Herbal Supplements (herbal supplements): This category includes a wide range of plant-derived products used for various purposes. Examples include:

   • Echinacea (Echinacea): Used to support the immune system and prevent or treat colds.
   • GINSENG (ginseng): Used to improve energy, cognitive function, and overall vitality.
   • St. John’s Wort (St. John’s wort): Used to treat mild to moderate depression (but can interact with other medications).
   • Milk Thistle (milk thistle): Used to support liver health.

6. Glucosamine and Chondroitin (glucosamine and chondroitin): These supplements are often used to relieve joint pain and improve joint function in people with osteoarthritis.

7. Melatonin (melatonin): A hormone that regulates sleep, often used to treat insomnia and jet lag.

8. Creatine (Creatine): Popular among athletes and bodybuilders to improve muscle strength and power.

9. Protein Powders (protein powders): Used to supplement protein intake, particularly by athletes and those trying to build muscle mass. Whey protein is a common type.

10. Iron Supplements (iron preparations): Used to treat iron deficiency anemia.

Understanding the specific types of dietary supplements available, their intended uses, and their ingredients is essential for making informed decisions about their use. It’s crucial to remember that while some supplements may offer potential benefits, they also carry risks, and it’s important to discuss their use with a healthcare professional.

II. Common Myths About БАДы (Dietary Supplements): Debunking Falsehoods

The market for dietary supplements is rife with misinformation and misleading claims. Separating fact from fiction is crucial for consumers to make informed decisions about their health. Here’s a breakdown of common myths about БАДы and the realities behind them:

A. Myth 1: “If it’s Natural, it’s Safe.” (If this is natural, then it is safe.)

• Reality: This is perhaps the most dangerous myth surrounding dietary supplements. The term “natural” is often used as a marketing tool to imply safety, but it is not an accurate indicator. Many substances found in nature are highly toxic. Consider poisonous mushrooms, cyanide in apple seeds (in high quantities), or the potent effects of certain herbal remedies.

  • Example: Some herbal supplements, like comfrey, contain pyrrolizidine alkaloids, which can cause severe liver damage. Even seemingly benign herbs can interact negatively with medications. St. John’s Wort, for example, can reduce the effectiveness of certain antidepressants, birth control pills, and blood thinners.

  • Key Point: The source of a substance (natural vs. synthetic) is less important than its chemical composition and potential effects on the body. Always research the ingredients in a supplement and consider potential interactions with medications or pre-existing health conditions.

B. Myth 2: “Dietary Supplements are strictly Regulated and Tested for Safety and Effectivence.” (Bades are strictly regulated and checked for safety and efficiency.)

• Reality: As previously discussed, dietary supplements generally do not undergo the same rigorous pre-market testing and approval processes as pharmaceuticals. Regulatory oversight varies considerably from country to country. In many jurisdictions, including the US, manufacturers are primarily responsible for ensuring the safety of their products.

  • Example: The lack of pre-market approval means that supplements can be sold even if there is limited scientific evidence supporting their purported benefits. Furthermore, the actual ingredients in a supplement may not always match what is listed on the label. Studies have found instances of adulteration, contamination, and inaccurate labeling of dietary supplements.

  • Key Point: Consumers cannot assume that all dietary supplements are safe and effective simply because they are available for purchase. Due diligence is required, including researching the manufacturer, looking for third-party certifications (see below), and consulting with a healthcare professional.

C. Myth 3: “More is better. A Higher Dose of a vitamin orral is always More Beneficial.” (More – better. A higher dose of vitamin or mineral is always more useful.)

• Reality: This is a dangerous oversimplification. While essential nutrients are vital for health, taking excessive amounts can lead to adverse effects. Many vitamins and minerals have tolerable upper intake levels (ULs), which represent the maximum daily intake that is unlikely to cause adverse health effects in most people.

  • Example: Taking excessive amounts of Vitamin A can lead to liver damage, bone pain, and birth defects. High doses of iron can cause gastrointestinal distress and, in severe cases, organ damage. Even water-soluble vitamins, like Vitamin C, can cause diarrhea and other digestive issues in high doses.

  • Key Point: Follow the recommended dosage on the supplement label and consult with a healthcare professional to determine the appropriate dosage for your individual needs. Taking more than the recommended amount is not necessarily beneficial and can be harmful. Consider also that many processed foods are fortified with vitamins and minerals; supplementation on top of this could push intake over the UL.

D. Myth 4: “Dietary Supplements Can Cure Or Treat Diseases.” (Bad can cure or treat diseases.)

• Reality: As stated in the required disclaimer on supplement labels, dietary supplements are not intended to diagnose, treat, cure, or prevent any disease. This is a crucial distinction from pharmaceuticals, which are rigorously tested and approved for specific medical uses.

  • Example: While some supplements may offer potential benefits for managing certain conditions (e.g., omega-3 fatty acids for heart health), they should never be used as a replacement for conventional medical treatment. Relying solely on supplements to treat a serious illness can have devastating consequences.

  • Key Point: Dietary supplements should be considered as adjuncts to a healthy lifestyle and conventional medical care, not as a substitute. Always consult with a healthcare professional for diagnosis and treatment of medical conditions.

E. Myth 5: “If a Dietary Supplement is Sold in a Health Food Store, It Must Be Safe and Effective.” (If dietary supplement is sold in a healthy food store, then it is safe and effective.)

• Reality: The location where a dietary supplement is sold does not guarantee its safety or effectiveness. Health food stores are businesses, and they may sell products that are not scientifically proven to be beneficial or that may even pose risks.

  • Example: A health food store may carry a wide range of herbal supplements, some of which may have limited evidence of effectiveness or may interact with medications. The staff at a health food store may not have the medical expertise to provide personalized advice about dietary supplements.

  • Key Point: Be a critical consumer regardless of where you purchase a dietary supplement. Do your own research, look for reputable brands, and consult with a healthcare professional before taking any new supplement.

F. Myth 6: “Dietary Supplements are all-Natural and theFore cannot interct with medications.” (Bades are all natural, so they cannot interact with medicines.)

• Reality: This is a particularly dangerous myth. Many dietary supplements, especially herbal supplements, can interact with prescription and over-the-counter medications. These interactions can alter the effectiveness of the medications or increase the risk of side effects.

  • Example: St. John’s Wort, as mentioned earlier, can interact with antidepressants, birth control pills, and blood thinners. Vitamin K can interfere with the action of blood thinners like warfarin. Grapefruit juice can interact with a variety of medications, including statins and calcium channel blockers.

  • Key Point: Always inform your healthcare professional about all the medications and dietary supplements you are taking, including herbal remedies. This will allow them to assess potential interactions and adjust your treatment plan accordingly.

G. Myth 7: “EVERYONE NEEDS To TAKE A Multivitamin to Stay Healthy.” (Everyone needs to take polyvitamins to stay healthy.)

• Reality: Most healthy individuals who eat a balanced diet do not need to take a multivitamin. While multivitamins can help fill in nutritional gaps, they are not a substitute for a healthy lifestyle.

  • Example: A person who eats a varied diet rich in fruits, vegetables, whole grains, and lean protein is likely to obtain sufficient amounts of most vitamins and minerals. However, certain individuals may benefit from specific supplements, such as pregnant women (folic acid), older adults (vitamin D), or people with certain medical conditions.

  • Key Point: The need for a multivitamin or any other dietary supplement should be determined on an individual basis, based on dietary habits, health status, and other factors. A healthcare professional can help assess your nutritional needs and recommend appropriate supplements if necessary.

H. Myth 8: “Third-Party Certification Guaranteees that a Dietary Supplement is Safe and Effective.” (Certification of the third party guarantees that the dietary supplement is safe and effective.)

• Reality: While third-party certification can provide some assurance of quality and purity, it does not guarantee safety or effectiveness. Third-party certification programs typically verify that a supplement contains the ingredients listed on the label, that it does not contain harmful contaminants, and that it is manufactured according to Good Manufacturing Practices (GMPs).

  • Example: Common third-party certification programs include USP (United States Pharmacopeia), NSF International, and ConsumerLab.com. These programs test supplements for quality and purity, but they do not evaluate their effectiveness or safety in clinical trials.

  • Key Point: Third-party certification can be a helpful tool for choosing reputable dietary supplements, but it should not be the sole factor in your decision. You should still do your own research and consult with a healthcare professional. Be sure to understand what the certification actually means and what standards were used.

I. Myth 9: “If a Dietary Supplement is Advertered on Television Or Online, It Must Be Legitimate.” (If dietary supplement is advertised on television or on the Internet, then it is legal.)

• Reality: Advertising does not equate to legitimacy or safety. The dietary supplement industry is often subject to deceptive marketing practices and unsubstantiated claims.

  • Example: Many dietary supplements are advertised with testimonials from individuals who claim to have experienced miraculous results. These testimonials are often anecdotal and are not supported by scientific evidence.

  • Key Point: Be wary of dietary supplement advertisements that make unrealistic claims, use deceptive language, or rely on testimonials rather than scientific data. Look for supplements that are supported by scientific research and that are manufactured by reputable companies. Report suspicious or misleading advertising to the appropriate regulatory agencies.

J. Myth 10: “I Don’T NEED To Tell My Doctor ABOUT THE DIETARY SUPLEMENTS I’M TAKAUSE THIS AREY ‘Natural’ and Canomet CAUSE ANY HARM.” (I do not need to tell the doctor about the dietary supplements, because they are “natural” and cannot harm.)

• Reality: This is extremely dangerous. As discussed previously, dietary supplements can interact with medications and affect medical conditions. Your doctor needs to have a complete picture of your health, including all medications and supplements you are taking, to provide the best possible care.

  • Example: Certain supplements can affect blood clotting, blood pressure, or blood sugar levels. This can be particularly problematic for patients undergoing surgery or those with chronic conditions like diabetes or heart disease.

  • Key Point: Always inform your healthcare professional about all the medications and dietary supplements you are taking. This is crucial for ensuring your safety and preventing potentially harmful interactions. Keep a list of all supplements, including the brand name, dosage, and frequency, and bring it with you to your medical appointments.

III. Potential Health Risks Associated with БАДы (Dietary Supplements)

While some dietary supplements may offer potential benefits, it’s crucial to acknowledge the potential health risks associated with their use. These risks can range from mild side effects to serious adverse events, and they are often underestimated.

A. Adverse Reactions and Side Effects:

1. Gastrointestinal Issues: Many dietary supplements can cause gastrointestinal distress, including nausea, vomiting, diarrhea, constipation, and abdominal pain. These side effects are often dose-dependent and may be more common in individuals with sensitive digestive systems.

   • Examples: Iron supplements are known to cause constipation and nausea. Magnesium supplements can cause diarrhea. High doses of vitamin C can also lead to digestive upset. Herbal supplements can sometimes cause gastrointestinal irritation.

2. Allergic Reactions: Individuals may be allergic to ingredients in dietary supplements, including herbs, vitamins, minerals, or excipients (inactive ingredients). Allergic reactions can range from mild skin rashes to severe anaphylaxis.

   • Examples: People with allergies to ragweed may also be allergic to echinacea. Individuals with shellfish allergies may react to glucosamine supplements derived from shellfish.

3. Headaches and Dizziness: Some dietary supplements can cause headaches, dizziness, or lightheadedness. These side effects may be due to changes in blood pressure, blood sugar, or neurotransmitter levels.

   • Examples: Caffeine-containing supplements can cause headaches, anxiety, and insomnia. Ginkgo biloba can sometimes cause dizziness.

4. Liver Damage: Certain dietary supplements, particularly herbal supplements, have been linked to liver damage (hepatotoxicity). This can range from mild elevations in liver enzymes to severe liver failure.

   • Examples: Comfrey, as mentioned earlier, contains pyrrolizidine alkaloids that can damage the liver. Anabolic steroids, often marketed as dietary supplements for muscle building, can cause severe liver damage. Green tea extract, in high doses, has also been linked to liver problems in some individuals.

5. Kidney Problems: Some dietary supplements can strain the kidneys or increase the risk of kidney stones.

   • Examples: High doses of vitamin C can increase the risk of oxalate kidney stones. Creatine supplements, in some individuals, can lead to kidney dysfunction, especially in those with pre-existing kidney problems.

6. Cardiovascular Effects: Certain dietary supplements can affect heart rate, blood pressure, or blood clotting, potentially increasing the risk of cardiovascular events.

   • Examples: Ephedra, a stimulant formerly used in weight loss supplements, was linked to increased risk of heart attacks and strokes and was eventually banned by the FDA. Bitter orange, a common ingredient in weight loss supplements, contains compounds similar to ephedra and may pose similar risks.

7. Interference with Surgical Procedures: Some dietary supplements can increase the risk of bleeding during or after surgery.

   • Examples: Garlic, ginger, ginkgo biloba, and vitamin E can all thin the blood and increase the risk of bleeding. It is important to inform your surgeon about all the dietary supplements you are taking before undergoing any surgical procedure.

B. Interactions with Medications:

As previously emphasized, dietary supplements can interact with prescription and over-the-counter medications, altering their effectiveness or increasing the risk of side effects. This is a significant concern, especially for individuals taking multiple medications.

1. Drug Metabolism: Some supplements can affect the enzymes in the liver that are responsible for metabolizing drugs. This can either increase or decrease the levels of drugs in the bloodstream.

   • Examples: St. John’s Wort can induce liver enzymes, which can reduce the levels of many drugs, including antidepressants, birth control pills, and blood thinners. Grapefruit juice can inhibit liver enzymes, which can increase the levels of certain drugs, potentially leading to toxicity.

2. Drug Absorption: Some supplements can interfere with the absorption of drugs in the gut.

   • Examples: Calcium supplements can bind to certain antibiotics, such as tetracycline and quinolones, reducing their absorption and effectiveness.

3. Drug Excretion: Some supplements can affect the kidneys’ ability to excrete drugs, potentially leading to drug accumulation and toxicity.

   • Examples: Licorice root can increase sodium retention and potassium excretion, which can affect the levels of certain drugs, such as diuretics.

4. Additive Effects: Some supplements can have similar effects to medications, potentially leading to additive effects and increased risk of side effects.

   • Examples: Taking a sedative herbal supplement along with a prescription sleeping pill can increase the risk of drowsiness and impaired coordination.

C. Contamination and Adulteration:

One of the most concerning risks associated with dietary supplements is the potential for contamination and adulteration. This means that the supplement may contain ingredients that are not listed on the label, or it may be contaminated with harmful substances.

1. Heavy Metals: Dietary supplements can be contaminated with heavy metals, such as lead, mercury, arsenic, and cadmium. These metals can accumulate in the body and cause various health problems, including neurological damage, kidney damage, and cancer.

   • Examples: Certain herbal supplements sourced from contaminated soil may contain high levels of heavy metals.

2. Pesticides: Herbal supplements can be contaminated with pesticides if the plants were grown using pesticides.

3. Bacteria and Mold: Dietary supplements can be contaminated with bacteria and mold if they are not manufactured and stored properly.

4. Undeclared Pharmaceuticals: Some dietary supplements, particularly those marketed for weight loss, sexual enhancement, or muscle building, have been found to contain undeclared pharmaceuticals. This is a serious problem because consumers may unknowingly be taking drugs that are not appropriate for them or that can interact with their medications.

   • Examples: Weight loss supplements have been found to contain sibutramine, a prescription drug that was withdrawn from the market due to cardiovascular risks. Sexual enhancement supplements have been found to contain sildenafil (Viagra) or tadalafil (Cialis), which can be dangerous for people with heart conditions or those taking nitrates. Muscle building supplements have been found to contain anabolic steroids, which can have serious health consequences.

D. Specific Risks for Certain Populations:

Certain populations are at higher risk of experiencing adverse effects from dietary supplements.

1. Pregnant and Breastfeeding Women: Many dietary supplements are not safe for pregnant or breastfeeding women. Some supplements can harm the developing fetus or infant.

   • Examples: High doses of vitamin A can cause birth defects. Certain herbal supplements can stimulate uterine contractions or affect lactation.

2. Children: Children are more vulnerable to the effects of dietary supplements than adults. Overdosing on certain vitamins or minerals can be particularly dangerous for children.

   • Examples: Iron poisoning is a leading cause of accidental poisoning in children.

3. Older Adults: Older adults are more likely to be taking multiple medications, which increases the risk of drug interactions. They are also more likely to have underlying health conditions that can be exacerbated by dietary supplements.

4. Individuals with Chronic Diseases: People with chronic diseases, such as heart disease, diabetes, kidney disease, or liver disease, should be particularly cautious about taking dietary supplements. Supplements can interact with their medications or worsen their underlying conditions.

E. Lack of Standardization:

The lack of standardization in the dietary supplement industry is a major concern. This means that the quality, purity, and potency of dietary supplements can vary widely from batch to batch and from brand to brand.

1. Variability in Active Ingredient Content: The amount of active ingredient in a dietary supplement may not always match what is listed on the label. Studies have shown that some supplements contain significantly less or significantly more of the active ingredient than claimed.

2. Variability in Bioavailability: Even if a dietary supplement contains the stated amount of active ingredient, the bioavailability (the extent to which the ingredient is absorbed and used by the body) can vary.

3. Variability in Manufacturing Practices: Different manufacturers may use different manufacturing practices, which can affect the quality and purity of the final product.

IV. Guidelines for Safe and Informed Supplement Use

Given the potential risks associated with dietary supplements, it’s essential to follow guidelines for safe and informed use. This includes researching supplements, consulting with healthcare professionals, and being a critical consumer.
