Know about drugs with Chula pharmacists: Are dietary supplements really necessary?

    The most talked-about topic this week revolves around celebrity entrepreneurs and online product companies boasting massive sales figures. This has caught the attention of every TV channel, with the focus shifting to the harm caused to unsuspecting victims. Whether these high-profile bosses are acting within the law is yet to be determined, but as we know, in Thailand, almost anything is possible. Although we may assume that certain practices violate the law, the reality is often more complex than it seems, and legal consequences might not always follow.

    One product that has been making waves is dietary supplements, or as they’re commonly referred to, “supplements.” In truth, it’s not just one company involved in this sector; many businesses, both local and international, are part of the booming supplement industry.

    With this in mind, today we’ll provide a brief overview of dietary supplements to help you make informed, safe, and worthwhile choices.

    First, it’s essential to understand that the word “supplement” indicates something additional, not a primary solution. This means you should focus on managing the core aspects of your health first. Supplements should only be considered when there is a need to support what’s lacking. If you keep this in mind, you’ll be better equipped to critically assess the advertising and marketing claims surrounding these products.

    Dietary supplements are products consumed alongside regular food, typically containing nutrients and other compounds like vitamins, amino acids, fatty acids, herbal extracts, or synthetic substances. These often come in various forms, such as tablets, capsules, powders, or liquids.

    While dietary supplements are intended to promote overall health, they are not designed to prevent or cure diseases. Yet, many advertisements make exaggerated claims, suggesting these products can prevent cancer, detoxify the body, or treat numerous conditions—claims that often verge on misleading.

    Legally, both in Thailand and many other countries, the focus is on the safety and quality standards of supplements. This includes ensuring products are free from harmful microbes and other contaminants. However, the concentration of active ingredients in supplements may not always be tightly regulated. What’s stated on the label may not always reflect the actual contents, as the potency of certain ingredients can degrade over time.

    In some cases, poorly regulated products might not even contain the beneficial substances they claim to. It’s important to remember that dietary supplements are not held to the same rigorous standards as medications. The focus is primarily on ensuring they are safe, rather than confirming their effectiveness in preventing or treating illnesses.

    When purchasing supplements, always buy from reputable sources with clear labeling. Check the manufacturing and expiration dates, and ensure the product has an official registration number from the Food and Drug Administration (FDA), which can be verified on the FDA’s website. Most importantly, approach the marketing of supplements with caution. Remember, these products are not cures, and not every supplement is suitable for everyone.

    Lastly, a word of caution for those with chronic conditions: ensure that any supplements you’re considering won’t interfere with your existing medical treatments or conditions, whether they’re natural or synthetic. Always verify this before taking any supplement. It’s best to consult a doctor or pharmacist to ensure the product is safe and appropriate for you.
