Quick Answer: What are health products and how do they work?
Health products include dietary supplements, functional foods, and herbal remedies that supply nutrients, plant compounds, or beneficial microbes the body uses for specific processes. They support wellness but do not treat or cure disease, and most take 4 to 12 weeks of consistent use to show measurable effects.

Dietary supplements like vitamins and minerals are good for overall health but you must consult a health care professional before taking them. You must also consult a doctor before giving health products to children or individuals with developing bodies.
Natural health products including herbal products like Turmeric Curcumin and homeopathic medicines can interact with other supplements or medications so be cautious. Health products are not meant to treat or cure diseases and products that claim to treat or cure diseases are regulated as drugs.
Introduction to Health Products
Health products range from vitamins to herbal remedies and functional foods[1]Dietary and Herbal Supplements — NCCIH View source, each regulated as a food rather than a drug[2]Dietary Supplements — MedlinePlus View source.
- Vitamins and minerals correct common dietary shortfalls
- Herbal and functional products add plant compounds and microbes
- All are sold as foods, not FDA-approved drugs
Regulation and Oversight
Health Canada’s Natural Health Products Directorate regulates natural health products including their sale, manufacture, packaging, labeling, importation, distribution and storage. These health products are sold through various channels like pharmacies, stores and online.
The FDA regulates dietary supplements to ensure their safety and truthful labeling but does not evaluate their effectiveness before marketing.

Each company must comply with Good Manufacturing Practices (GMPs) to ensure the quality and purity of their products. The company is responsible for product safety, maintaining compliance with FDA regulations and ensuring labeling is truthful and not misleading.
| Regulatory Body | Region | Primary Role |
|---|---|---|
| Food and Drug Administration (FDA) | United States | Regulates dietary supplements as a category of food. Focuses on manufacturing standards (GMPs) and labeling claims. Can take action against unsafe products after they are on the market. |
| Health Canada | Canada | Regulates Natural Health Products (NHPs) through pre-market review. Products must have a license (NPN or DIN-HM) to be sold, demonstrating safety and efficacy. |

-
Traditional medicines like those used in Ayurvedic or Unani practices can be beneficial but their safety and efficacy must be evaluated.
Dietary Supplements
Dietary supplements can be good for overall health but their effectiveness and safety vary widely. Supplements can have strong effects on the body and individuals may respond differently to the same product.
Many supplements like Calcium & Magnesium and Vitamin D are established and can support strong bones and overall health. Others, such as Zinc, are vital for immune function.
- Vitamins and minerals fill common dietary gaps in 1 daily dose
- Herbal extracts deliver concentrated plant compounds like polyphenols
- Probiotics supply beneficial microbes for gut and immune balance
But some supplements can have strong effects and interact with medications or affect medical tests so be cautious. For a deeper dive into using supplements safely, resources like the National Center for Complementary and Integrative Health (NCCIH) offer valuable guidance.
Consumers must consult a health care professional before taking dietary supplements especially if they have a chronic condition or are taking medications. If a bad reaction occurs, seek medical care immediately.
Safety and Efficacy
Because supplements are not reviewed for effectiveness before sale, third-party testing and label literacy matter for consumer safety[3]Questions and Answers on Dietary Supplements — FDA View source.
-
Safety and efficacy of health products are important considerations for consumers and can be evaluated through research and clinical trials.
-
Some health products like those with contaminated substances or incorrect ingredients can be harmful and companies may voluntarily recall them.

Health Product Labels
Understanding health product labels is important for consumers who want to make informed decisions when taking dietary supplements or natural health products. Each dietary supplement label has key information like the list of active ingredients, serving size and any interactions with other supplements or medications. Labels may also have health claims like supporting immune health or heart health but note that these statements must be accompanied by a disclaimer that says they have not been evaluated by the FDA.
In Canada, Health Canada regulates the labeling of natural health products to ensure they are safe and effective for consumers. When choosing a health product look for a Natural Product Number (NPN) or Drug Identification Number (DIN) on the label—these numbers mean the product has been reviewed and authorized for sale by Health Canada.
| Label Section | What It Tells You |
|---|---|
| Supplement Facts Panel | The standardized panel listing all active ingredients and their amounts. |
| Serving Size | The recommended amount to take at one time. All nutrient amounts are based on this serving size. |
| Amount Per Serving | Lists each nutrient and the specific quantity (in mg, mcg, or IU). |
| % Daily Value (%DV) | How much a nutrient in a single serving contributes to a daily diet, based on a 2,000-calorie diet. |
| Other Ingredients | Lists inactive ingredients like fillers, binders, and flavorings. Important for people with allergies. |

Frequently Asked Questions
What is the difference between a supplement and a drug? +
Drugs are regulated by the FDA to prove safety and efficacy before approval. Dietary supplements do not require pre-market approval — manufacturers are responsible for safety, and claims cannot include disease treatment.
Are herbal products the same as supplements? +
Herbal products are a subset of the supplement category. They contain plant-derived compounds and are regulated as dietary supplements in the US, though traditional use and some clinical research support many of them.
How do I know if a health product is effective? +
Look for products with clinical research on the specific form and dose, third-party testing for purity and potency, and transparent labeling with exact ingredient amounts.
Can health products interact with medications? +
Yes — many supplements interact with prescription drugs. St. John's Wort, high-dose vitamin E, fish oil, and garlic supplements can all affect drug metabolism or blood clotting. Always inform your prescriber about supplements you take.
How are supplements regulated? +
In the US, the FDA regulates supplements under the 1994 DSHEA law as foods, not drugs. Manufacturers are responsible for safety, but products are not reviewed for effectiveness before sale. Third-party seals like USP or NSF add an extra layer of quality verification.
Are natural health products safe? +
Most are safe at recommended doses, but natural does not mean risk-free. About 23,000 US emergency visits per year involve supplements, often from stimulants or drug interactions. Always check with a pharmacist if you take prescription medication.
Do health products actually work? +
Evidence varies widely by ingredient and dose. Some, like vitamin D, omega-3, and probiotics, have strong support from clinical trials, while many others do not. Choose products with human studies and 3rd-party testing behind them, not marketing claims.
How long should I take a supplement? +
Most supplements need 4 to 12 weeks of daily use before benefits appear. Some, like vitamin D, are taken long term to maintain healthy levels. Reassess with your doctor every 3 to 6 months to confirm a supplement is still needed.
