Look around a store pharmacy, and you’ll find shelves full of bottles that claim to help you sleep better, build stronger bones, or focus more effectively, or strengthen your immune system. It’s a type of food supplement, and, although they’re widely grown and used, many people still don’t fully understand what they are, how they’re regulated, or how they differ from medicines. This guide will cover all the details.
What Exactly Is a Food Supplement?
A food supplement (also referred to as a dietary supplement) is a product intended to supplement the diet or provide certain nutrients or other beneficial substances when your diet is insufficient. Remember, the term here is “supplement,” and these products are designed to supplement a healthy diet and are not meant to replace food, nor are they intended to treat a medical condition. Supplements are usually very potent and in a concentrated form with the dose controlled, for example, as tablets, capsules, soft gels, powders, gummies, or liquid drops. Part of what makes them different than regular foods, even if the nutrients (such as vitamin C or omega-3s) are something you could obtain in your diet, is this.
Common Categories of Food Supplements
The types of ingredients in supplements are numerous, but the most common ones can be divided into a few general categories:
- Common nutrient deficiencies are sometimes filled with the addition of vitamins and minerals, such as vitamin D, vitamin B12, iron, magnesium, calcium, and zinc.
- Botanical and herbal extracts are derived from plants, traditionally used for various well-being purposes, such as turmeric, ginkgo biloba, ashwagandha, and echinacea.
- Athletes and people interested in maintaining muscle mass favor taking amino acids and protein-based supplements.
- Probiotics are living microorganisms used to promote healthy guts and digestive function.
- In this regard, fatty acids, especially the omega-3 fatty acids in fish oil or algae, come to mind.
- Enzymes — to help digest certain foods.
- The other specialty compounds such as fiber, melatonin, coenzyme Q10, and collagen.
How Are Food Supplements Regulated?
Among the most misunderstood factors of supplements is regulation, and it varies greatly from region to region.
In the United States the Dietary Supplement Health and Education Act (DSHEA) categorizes supplements as a type of food, not drugs. That is, manufacturers are not required to obtain approval from a regulatory body before introducing a product to the market, and they are not allowed to claim that a product treats, cures, or prevents disease. The U.S. Food and Drug Administration has a supplement information page that is useful for further information regarding these rules: FDA Dietary Supplements
European Union and UK: Supplements are also considered food, but under harmonized EU legislation, including the EU Food Supplements Directive, which establishes guidelines for the vitamins and minerals permitted in supplements and for labels. See the European Food Safety Authority’s overview of food supplements.
Other regions: Other regions have food-like (like the US/EU) to more drug-like frameworks with pre-market approval and more stringent efficacy evidence.
What Supplements Are and What They’re Not
It is worthwhile to make clear boundaries:
- They help close nutritional gaps, promote overall health, or help individuals obtain specific nutrients that are difficult to acquire from food alone, such as vitamin D for areas with low sun exposure or omega-3 fatty acids for people who don’t consume fish.
- Not only are they not a replacement for proper nutrition, but they are not alternatives to the medication prescribed by doctors, nor are they cures for any type of disease. If it seems too good to be true, it probably is, and it’s particularly important to be skeptical of treatments that promise to “cure” or “reverse” a medical condition.
Why People Use Food Supplements
Individuals seek out supplements for different reasons: to meet dietary restrictions (vegan or vegetarian lifestyle or missing specific nutrients like B12 and iron), for increased nutritional requirements at specific life stages (pregnancy or aging), for particular health benefits (joint support or athletic performance), and/or out of a desire for “insurance” if dietary patterns are lacking.
However, supplements should really be used in conjunction with a healthy lifestyle that involves a diverse diet, exercise and medical advice, especially for those with health problems or who are taking medication, as certain supplements can interfere with prescription drugs
Conclusion
Food supplements are not intended to diagnose, treat, or cure disease but are intended to help fill nutritional gaps for overall well-being. They are regulated as food (with different regulations in different countries), they are available in a concentrated dose in capsules, powder, etc., and they range from simple vitamins to specific compounds such as probiotics and omega-3 fats. Knowing what supplements are and aren’t helps you to make better decisions and also to have an appropriate level of healthy skepticism towards the claims that are made about them. As usual, consult a doctor or pharmacist for any new supplement, particularly if pregnant, on a healthcare regimen, or taking other medications.
