In the modern health consumer market, natural health products (NHPs) and drugs/medicines are often confused. Some believe that taking health supplements is equivalent to treating illness, while others have unrealistic expectations. However, there are significant differences between the two in terms of legal status, functional positioning, and usage.
Correctly understanding the difference between these two types of products will not only help consumers make rational choices, but also avoid health risks caused by misunderstandings.
1. Differences in Legal Definitions
Drugs
Drugs are substances used to diagnose, treat, alleviate or prevent diseases . They must undergo rigorous clinical trials to verify their efficacy and safety before they can be approved for marketing.
-
Approval agency: Health Canada ’s drug department is responsible for approval in Canada, and the FDA is responsible for approval in the United States.
-
Review process: Large-scale clinical studies are required, usually divided into Phase I–III trials, to verify efficacy, side effects, and long-term safety.
-
Label requirements: Indications, usage and dosage, adverse reactions and warnings must be clearly marked.
Natural Health Products (NHPs)
NHPs include vitamins, minerals, herbal extracts, probiotics, amino acids, and some traditional medicine preparations. In Canada, they must obtain an NPN (Natural Product Number) before they can be legally sold.
-
Approval body: Natural and Non-prescription Health Products Directorate, Health Canada.
-
Audit content: Focuses primarily on safety, ingredient authenticity, and appropriate use , rather than clinical efficacy.
-
Labeling requirements: Do not claim to "treat a certain disease", only state "support health" or "help maintain function".
Summary : Drugs are centered around “treatment,” while NHPs are positioned around “supporting health.”
2. Differences between Function and Purpose
-
Function of the drug
-
Treating a specific disease or condition
-
Fast-acting, targeting specific pathological mechanisms
-
Examples: antibiotics, blood pressure medication, insulin
-
-
Functions of natural health products
-
Fill daily nutritional gaps
-
Help maintain the body's normal physiological functions
-
For example: Vitamin D for bone health, probiotics for digestive balance, and shiitake mushroom extract for immune support.
-
In other words, medicines are "firefighters" and health products are more like "daily guardians."
3. Differences between production and supervision
-
Pharmaceutical factories : They must meet pharmaceutical-grade GMP requirements, and production lines are often shared with injections, prescription drugs, etc., and supervision is extremely strict.
-
NHP factories : GMP certification is also required, but the focus is on ensuring the authenticity of raw materials, accurate dosage, safety and compliance, rather than proving therapeutic effects.
-
Regulatory consequences : If a drug is found to have serious side effects, it may be recalled immediately; if NHPs have misleading labels or fail testing, their NPN qualifications may be revoked.
4. Common Misunderstandings of Consumers
-
Myth 1: NHPs can replace medications . False. NHPs are not a substitute for prescription medications, nor should they be used as the sole treatment for serious illnesses.
-
Myth 2: Natural = safe ❌ False. Natural ingredients can also cause allergies or interact with medications. For example, ginseng may affect the effectiveness of the anticoagulant warfarin.
-
Myth 3: Medication has significant side effects, while health supplements are more gentle . Partially true. Medication has stronger mechanisms of action, so its side effects are more pronounced. Health supplements are safer, but their effects are also limited.
5. The Principle of Rational Choice
-
Clarify the purpose : If it is for the treatment of diseases, you should follow the doctor's prescription; if it is for daily health support, you can choose NPN certified products.
-
Check for compliance : Choose products with an NPN number (in Canada) or NSF/GMP certification.
-
Avoid overlapping risks : If you are taking prescription medications, you should consult a medical professional before using health supplements.
-
Long-term perspective : Drugs are used for short-term or long-term disease management; health supplements are more suitable as a supplement to daily health management.
VI. Summary
Medicines and natural health products are not opposites, but complementary.
-
Drugs: used to treat diseases, with sufficient scientific evidence and both risks and benefits.
-
Natural health products: used for health support, emphasizing safety and nutritional supplementation.
For consumers, the most rational attitude is:
-
Take medicine as directed by your doctor when you are sick
-
Maintain health in daily life through healthy diet, regular sleep and rest, and appropriate selection of compliant health products
Choosing health products with NPN numbers is a responsible way to manage your health.
