    Study Notes

    Dietary Supplements: Introduction

    • Dietary supplements (DS) are defined by the FDA as orally consumed products intended to supplement the diet. They may include vitamins, minerals, herbs, botanicals, amino acids, enzymes, and live microorganisms.
    • Common terms used to describe supplements include nutraceuticals, natural products, herbs, botanicals, and phytochemicals.
    • Three common reasons adults use dietary supplements: improve overall health (45%), maintain health (33%), and promote bone health (25%).
    • Many obtain supplement information through television (73%), magazines/radio (both 30%), newspapers (13%), friends (8%), and store displays (5%).
    • A significant percentage (25%) of people do not disclose their use to healthcare providers.

    Dietary Supplement Legislation and Regulation

    • The Dietary Supplement Health and Education Act (DSHEA) of 1994 regulates dietary supplements.
    • Dietary supplements are regulated under food standards, not the stricter purity and potency standards for prescription/non-prescription drugs.
    • Clinical trials are usually not required to prove safety and efficacy before supplements are marketed, unlike drugs.
    • Manufacturing standards for dietary supplements must meet current Good Manufacturing Practices (cGMP), though these standards are less rigorous than for pharmaceuticals.

    Marketing Restrictions and Implementation

    • Dietary supplements cannot be marketed to diagnose, treat, cure, or prevent diseases.
    • They can make structure-function claims (e.g. supports healthy cholesterol), but these do not imply a specific disease state.
    • Pre-market approval processes are less rigorous compared to drugs, leading to challenges in enforcing marketing restrictions based on clinical evidence.
    • The 'buyer-beware' market environment makes it hard for regulatory bodies to monitor and enforce compliance effectively.
    • Exceptions exist for new dietary ingredients, needing FDA safety evidence before marketing. If a supplement is unsafe or misleading, the FDA can take action (e.g. warning or recall).

    Labeling Requirements

    • Dietary supplement labels must include the product's name, "dietary supplement", net quantity of contents, manufacturer information, and directions for use.
    • Supplement Facts panels must list serving size, ingredients, amounts, and percent daily values.

    Misbranding

    • Misbranding means labeling that violates regulations, leading to misleading or false information about products. This includes failure to comply with labeling requirements or making false or misleading statements.

    Dietary Supplement Claims

    • Dietary supplement claims are categorized into health claims, nutrient content claims, and structure/function claims.
    • Health claims and nutrient content claims require FDA approval.
    • Structure/function claims must include a disclaimer stating the product has not been evaluated by the FDA and is not intended to diagnose, treat, cure, or prevent disease.

    Adverse Effects Reporting

    • Consumers and healthcare professionals are advised to report related adverse effects to FDA's MedWatch program.

    Adulteration

    • Adulteration means a supplement presents unreasonable risk, lacks safety evidence, is deemed hazardous, or contains harmful ingredients.
      • Intentional adulteration involves intentionally adding prescription drugs to enhance efficacy.
      • Unintentional adulteration involves contamination (e.g., heavy metals or microbes) during manufacturing.

    Quality Assurance

    • Quality assurance programs assess dietary supplement composition and ensure that the content matches the label, but they don't guarantee safety or efficacy.

    Independent Testing Organizations

    • Independent organizations (e.g., USP) test dietary supplements for content and purity.

    Supplement Hazards

    • Supplements with fraudulent/misleading claims may: list specific diseases, claim efficacy similar to drugs, list unrelated conditions, have labeling issues, or provide benefits without risks.
    • Problems include exaggerated claims, omission of risk information, use of pseudo-medical terms, justification for higher price as "better", and quick relief promises.

    Communication Issues

    • Counsel patients to read labels, follow instructions, inform healthcare providers about supplement use, recognize that supplements aren't strictly regulated, recognize supplements won't always yield unrealistic results, and to keep a log of supplement use and adverse effects.
    • Generally discourage use of supplements during pregnancy and lactation unless safety and efficacy are well-documented.
