Natural dietary supplements: reviews and composition

I. Defining Natural Dietary Supplements (БАДы)

Dietary supplements, or БАДы (Biologicheski Aktivnye Dobavki) in Russian, occupy a significant space in the health and wellness landscape. They are concentrated sources of nutrients (vitamins, minerals, herbs, amino acids, etc.) or other substances with a nutritional or physiological effect, intended to supplement the normal diet. The “natural” qualifier implies that the ingredients are derived from plant, animal, or mineral sources with minimal synthetic processing. However, the term “natural” can be misleading, as even naturally derived substances can undergo various extraction and purification processes. It is crucial to understand the source, processing methods, and potential interactions of any БАД before consumption.

II. Categorization of Natural Dietary Supplements

Natural БАДы encompass a broad spectrum of products. Categorizing them based on their primary function or ingredient type provides a clearer understanding of their applications:

• Vitamins & Minerals: These are essential micronutrients required for numerous bodily functions. Natural sources are often favored, but synthetic versions are frequently added to БАДы due to cost and stability considerations. Examples include vitamin C (sourced from rose hips or acerola cherries), vitamin D (derived from lanolin or lichen), calcium (from seaweed or eggshells), and magnesium (from seawater or dolomite).
• Herbal Supplements: These contain extracts or powders from plants believed to possess medicinal properties. They are rooted in traditional medicine systems like Ayurveda, Traditional Chinese Medicine (TCM), and European herbalism. Examples include echinacea (for immune support), St. John’s Wort (for mood), ginseng (for energy), and turmeric (for inflammation).
• Probiotics & Prebiotics: Probiotics are live microorganisms intended to benefit the host by improving the gut microbiome. Prebiotics are non-digestible food ingredients that promote the growth of beneficial bacteria in the gut. Natural sources of probiotics include fermented foods like kefir, yogurt, and sauerkraut. Prebiotics are found in foods like garlic, onions, and asparagus.
• Omega-3 Fatty Acids: Essential fatty acids crucial for brain health, heart health, and reducing inflammation. The primary sources are fish oil (derived from fatty fish like salmon, mackerel, and sardines) and plant-based sources like flaxseed oil, chia seed oil, and algae oil.
• Amino Acids: The building blocks of proteins, essential for muscle building, tissue repair, and various metabolic processes. Natural sources include soy protein, whey protein, and brown rice protein. Individual amino acids like L-glutamine, L-arginine, and creatine are also commonly available.
• Enzymes: Biological catalysts that accelerate chemical reactions in the body. Digestive enzymes, like amylase, protease, and lipase, are used to improve digestion and nutrient absorption. Sources include fruits (papaya, pineapple) and fungi.
• Antioxidants: Substances that protect cells from damage caused by free radicals. Natural sources include berries, green tea, and grape seed extract. Examples include resveratrol, coenzyme Q10 (CoQ10), and vitamin E.
• Adaptogens: Herbs that are believed to help the body adapt to stress. Examples include ashwagandha, rhodiola rosea, and Siberian ginseng.
• Specialty Supplements: This category encompasses a diverse range of substances with specific purported benefits. Examples include glucosamine and chondroitin (for joint health), collagen (for skin and joint health), and melatonin (for sleep).

III. Understanding Ingredient Sourcing and Processing

The “natural” label does not guarantee purity or efficacy. The sourcing and processing methods significantly impact the quality of the final product.

• Sourcing:

  • Organic Certification: Look for organic certification from reputable organizations. This ensures that the ingredients are grown without synthetic pesticides, herbicides, and fertilizers.
  • Wildcrafted vs. Cultivated: Wildcrafted herbs are harvested from their natural habitat. Cultivated herbs are grown under controlled conditions. Both methods have their advantages and disadvantages. Wildcrafted herbs may be more potent but can be susceptible to contamination. Cultivated herbs offer better standardization and quality control.
  • Geographic Origin: The geographic origin of the ingredient can affect its nutrient content and potential contaminants. For example, herbs grown in polluted areas may accumulate heavy metals.
  • Sustainability: Consider the environmental impact of sourcing practices. Sustainable harvesting methods help protect natural resources.

• Processing:

  • Extraction Methods: The extraction method used to isolate the active compounds from the raw material can affect the potency and purity of the final product. Common methods include:
    • Solvent Extraction: Uses solvents like ethanol or hexane to extract the desired compounds. Concerns about residual solvent contamination exist.
    • Water Extraction: A gentler method that preserves more of the plant’s natural constituents.
    • CO2 Extraction: A supercritical fluid extraction method that uses carbon dioxide as a solvent. Considered a clean and efficient method.
  • Standardization: Standardization refers to the process of ensuring that each batch of a supplement contains a consistent amount of the active ingredient. Look for supplements that are standardized to a specific percentage of the active compound.
  • Manufacturing Practices: Look for supplements that are manufactured in facilities that adhere to Good Manufacturing Practices (GMP). GMP certification ensures that the product is consistently produced and controlled according to quality standards.
  • Testing: Third-party testing verifies the identity, purity, and potency of the ingredients. Look for supplements that have been tested by independent laboratories.
