Bades: the effect on the liver and kidneys

I. Understanding Dietary Supplements (БАДы) and Their Prevalence

The Russian market, like many others globally, has witnessed an exponential surge in the popularity and availability of dietary supplements (БАДы – Биологически Активные Добавки). These products, marketed as adjuncts to the diet, are intended to provide nutrients, vitamins, minerals, herbs, or other botanical compounds, amino acids, enzymes, and other substances that may be missing or not consumed in sufficient quantity in a person’s diet. The allure of БАДы lies in their perceived ability to enhance health, improve performance, prevent diseases, and even reverse aging, often without the need for prescriptions or medical supervision.

The reasons for this widespread adoption are multifarious. Modern lifestyles, characterized by processed foods, nutrient-depleted soils, and increased stress levels, contribute to nutritional deficiencies that consumers attempt to address with БАДы. Aggressive marketing campaigns, often leveraging celebrity endorsements and testimonials, further fuel consumer demand. The perceived naturalness and safety of these products, often juxtaposed against conventional pharmaceuticals, resonate with individuals seeking holistic and preventive healthcare solutions. Furthermore, the accessibility of БАДы through various channels, including pharmacies, online retailers, and direct marketing networks, makes them readily available to a wide consumer base.

However, this enthusiasm often overshadows the crucial need for informed consumption and awareness of potential risks, particularly regarding the impact of БАДы on vital organs such as the liver and kidneys. The regulatory landscape surrounding БАДы in Russia, while evolving, still faces challenges in ensuring consistent quality control, accurate labeling, and rigorous safety testing. This necessitates a cautious approach, demanding that consumers critically evaluate the claims made by manufacturers and consult with healthcare professionals before incorporating БАДы into their regimens. The potential for adverse effects, especially in vulnerable populations and when combined with other medications, warrants careful consideration.

II. The Liver: A Central Hub for Metabolism and Detoxification

The liver, the largest internal organ, plays a critical role in maintaining overall health and well-being. It functions as the body’s primary metabolic and detoxification center, responsible for processing nutrients absorbed from the digestive tract, synthesizing essential proteins, storing energy, and eliminating waste products and toxins from the bloodstream.

Key liver functions include:

• Bile Production: The liver synthesizes bile, a fluid essential for the digestion and absorption of fats and fat-soluble vitamins in the small intestine.
• Metabolism of Nutrients: The liver metabolizes carbohydrates, proteins, and fats, converting them into forms that the body can use for energy, growth, and repair. It also stores glucose as glycogen for later use.
• Detoxification: The liver filters blood from the digestive tract, removing harmful substances such as drugs, alcohol, and environmental toxins. It converts these substances into less toxic forms that can be eliminated from the body. This process involves a complex series of enzymatic reactions.
• Protein Synthesis: The liver synthesizes numerous proteins, including albumin (which maintains fluid balance), clotting factors (essential for blood coagulation), and transport proteins (which carry hormones, vitamins, and other substances throughout the body).
• Storage of Vitamins and Minerals: The liver stores vitamins A, D, E, K, and B12, as well as iron and copper.
• Hormone Regulation: The liver plays a role in regulating hormone levels, including thyroid hormones and steroid hormones.

Due to its central role in detoxification, the liver is particularly vulnerable to damage from various sources, including viral infections (hepatitis), alcohol abuse, non-alcoholic fatty liver disease (NAFLD), and exposure to toxins, including certain medications and dietary supplements. Liver damage can manifest in a variety of ways, ranging from mild elevations in liver enzymes to severe liver failure, cirrhosis, and liver cancer.

III. The Kidneys: Filtration and Waste Removal

The kidneys are a pair of bean-shaped organs located in the lower back, responsible for filtering waste products and excess fluids from the blood, which are then excreted in the urine. They play a crucial role in maintaining fluid balance, electrolyte balance, and blood pressure regulation.

Key kidney functions include:

• Filtration of Blood: The kidneys filter approximately 120-150 quarts of blood per day, removing waste products such as urea, creatinine, and uric acid, as well as excess fluids and electrolytes.
• Regulation of Fluid Balance: The kidneys regulate the amount of water in the body, ensuring that fluid intake and output are balanced.
• Regulation of Electrolyte Balance: The kidneys regulate the levels of electrolytes in the blood, such as sodium, potassium, calcium, and phosphate, which are essential for nerve and muscle function.
• Regulation of Blood Pressure: The kidneys produce hormones, such as renin, that help regulate blood pressure. They also control the amount of sodium and water in the body, which affects blood volume and blood pressure.
• Production of Erythropoietin: The kidneys produce erythropoietin, a hormone that stimulates the production of red blood cells in the bone marrow.
• Activation of Vitamin D: The kidneys activate vitamin D, which is essential for calcium absorption and bone health.

Like the liver, the kidneys are susceptible to damage from various factors, including diabetes, high blood pressure, glomerulonephritis (inflammation of the kidney’s filtering units), polycystic kidney disease, and exposure to toxins, including certain medications and dietary supplements. Kidney damage can lead to chronic kidney disease (CKD), which can progress to kidney failure, requiring dialysis or kidney transplantation.

IV. БАДы and Liver Toxicity: Mechanisms and Specific Examples

The liver’s role in metabolizing and detoxifying substances makes it particularly vulnerable to injury from БАДы. Several mechanisms can contribute to liver toxicity induced by БАДы:

• Direct Hepatotoxicity: Some ingredients in БАДы can directly damage liver cells (hepatocytes), leading to inflammation, necrosis (cell death), and impaired liver function. This can occur through various mechanisms, including oxidative stress, mitochondrial dysfunction, and disruption of cell membrane integrity.
• Idiosyncratic Reactions: In some individuals, БАДы can trigger an unpredictable and idiosyncratic immune response that damages the liver. This type of reaction is often not dose-dependent and can occur even with low doses of the supplement.
• Metabolic Activation: Some ingredients in БАДы are metabolized by the liver into toxic metabolites that cause liver damage.
• Drug-Induced Liver Injury (DILI): БАДы can interact with other medications, increasing the risk of drug-induced liver injury. This can occur through various mechanisms, including competition for metabolic enzymes and inhibition of drug transporters.
• Contamination: БАДы can be contaminated with heavy metals, pesticides, or other toxins that can damage the liver. Adulteration with undeclared pharmaceutical ingredients is also a significant concern.

Specific examples of БАДы associated with liver toxicity include:

• Anabolic Steroids: Used to build muscle mass, anabolic steroids are known to cause liver damage, including cholestasis (impaired bile flow), hepatocellular damage, and liver tumors.
• Herbal Supplements: Many herbal supplements have been linked to liver toxicity, including:
  • Kava (Piper Methyst): Used to reduce anxiety, kava has been associated with severe liver damage, including liver failure.
  • Green Tea Extract (Camellia sinensis): Concentrated green tea extract, particularly in weight loss supplements, has been linked to liver injury, likely due to high levels of catechins.
  • Black Cohosh (Actaea racemosa): Used to relieve menopausal symptoms, black cohosh has been associated with liver damage in some cases.
  • Chaparral (Larrea Tridentata): Historically used for various ailments, chaparral is known to be hepatotoxic and can cause severe liver damage.
  • Comfrey (Symphytum officinale): Contains pyrrolizidine alkaloids that are hepatotoxic and can cause veno-occlusive disease of the liver.
  • Germander (Teucrium chamaedrys): Used for weight loss, germander has been linked to hepatitis.
• Weight Loss Supplements: Many weight loss supplements contain ingredients that can damage the liver, such as:
  • Ephedra (Ephedra sinica): Previously used as a stimulant and weight loss aid, ephedra was banned in the United States due to its cardiovascular and liver toxicity.
  • Hydroxycut: Several formulations of Hydroxycut have been associated with liver injury, leading to product recalls.
• Muscle-Building Supplements: In addition to anabolic steroids, other muscle-building supplements containing ingredients such as creatine and certain amino acids have been implicated in liver damage in some cases.
• Vitamin Supplements: While generally considered safe, high doses of certain vitamins, such as vitamin A and niacin, can cause liver toxicity.

It is important to note that the incidence of liver toxicity from БАДы is difficult to determine accurately, as many cases go unreported or are misdiagnosed. Furthermore, the composition and quality of БАДы can vary widely, making it challenging to establish a definitive link between a specific product and liver injury.

V. БАДы and Kidney Toxicity: Mechanisms and Specific Examples

The kidneys are also vulnerable to damage from БАДы, although the mechanisms of toxicity may differ from those affecting the liver.

• Direct Nephrotoxicity: Some ingredients in БАДы can directly damage kidney cells, leading to inflammation, tubular necrosis (damage to the kidney tubules), and impaired kidney function.
• Crystal-Induced Nephropathy: Certain substances in БАДы can crystallize in the kidney tubules, leading to blockage and damage.
• Dehydration: Some БАДы, particularly those marketed for weight loss or athletic performance, can promote dehydration, which can strain the kidneys and increase the risk of kidney damage.
• Electrolyte Imbalances: Some БАДы can cause electrolyte imbalances, such as hypercalcemia (high calcium levels), which can damage the kidneys.
• Immunologically Mediated Nephritis: In rare cases, БАДы can trigger an immune response that attacks the kidneys, leading to glomerulonephritis or other forms of kidney inflammation.
• Contamination: As with liver toxicity, contamination of БАДы with heavy metals, pesticides, or other toxins can damage the kidneys.

Specific examples of БАДы associated with kidney toxicity include:

• Creatine: Used to enhance muscle performance, creatine supplementation has been linked to kidney damage in some individuals, particularly those with pre-existing kidney disease or those taking high doses. While often considered safe for healthy individuals at recommended doses, excessive intake or prolonged use warrants caution.
• Protein Supplements: High protein intake, particularly from supplements, can increase the workload on the kidneys and may accelerate the progression of kidney disease in individuals with pre-existing kidney problems.
• Nonsteroidal Anti-inflammatory Drugs (NSAIDs): While technically over-the-counter medications, NSAIDs are often taken in conjunction with other supplements for pain relief and inflammation. Chronic use of NSAIDs can damage the kidneys and increase the risk of kidney failure. It’s crucial to be aware of NSAID content in combination products or when taking them alongside other supplements.
• Herbal Supplements: Certain herbal supplements have been linked to kidney toxicity, including:
  • Aristolochic Acid: Found in some herbal remedies, particularly those used in traditional Chinese medicine, aristolochic acid is a potent nephrotoxin and can cause irreversible kidney damage and kidney cancer. It’s crucial to verify the absence of this substance in any herbal product.
  • Licorice (Glycyrrhiza glabra): Excessive consumption of licorice can lead to sodium and water retention, potassium loss, and high blood pressure, which can strain the kidneys.
  • Occupation (Averrhoa Carambola): In individuals with kidney disease, starfruit consumption can cause nephrotoxicity due to its high oxalate content.
• Vitamin C: While generally safe in moderate doses, high doses of vitamin C can increase oxalate excretion, which can lead to kidney stone formation in susceptible individuals.
• Weight Loss Supplements: As with liver toxicity, some weight loss supplements contain ingredients that can damage the kidneys, often by causing dehydration or electrolyte imbalances.

The risk of kidney toxicity from БАДы is generally higher in individuals with pre-existing kidney disease, diabetes, high blood pressure, or other risk factors for kidney problems. It’s vital for these individuals to consult with a healthcare professional before taking any БАДы.
