With hundreds of vitamins, minerals, herbal extracts, and nutraceuticals available today, choosing the right supplement can be confusing. The front of the bottle may highlight impressive numbers and promising benefits, but the real information is often hidden in the fine print.

Here are 10 things to check before buying a nutraceutical or dietary supplement.

1. Check the serving size first

Don’t compare products based only on the headline number of milligrams.

For example, “Magnesium 500 mg” could refer to 500 mg of elemental magnesium or 500 mg of a magnesium compound such as magnesium oxide, citrate, or glycinate.

Always check the serving size, number of capsules or tablets per serving, recommended daily servings, and amount of each nutrient per serving. Compare products based on the nutrients or active compounds delivered per recommended daily serving.

2. Look beyond the ingredient name

The quantity of an ingredient matters, but so does what that quantity represents.

This is particularly important for minerals. Calcium, for example, may be supplied as calcium carbonate or calcium citrate. The weight of the compound is not necessarily the same as the amount of elemental calcium.

A clear label should distinguish between the compound and the actual nutrient provided.

3. For herbal supplements, look for standardisation

Two products may both contain “500 mg of herbal extract” but may not contain the same level of compounds associated with the extract.

Standardisation indicates that an extract is produced to contain a specified level of one or more characteristic compounds or markers. This provides greater clarity about what is present.

However, standardisation alone does not prove effectiveness. The evidence supporting the ingredient and dose still matters.

4. Check the form of the nutrient

The same nutrient can exist in different chemical forms, which may differ in absorption, stability, tolerability, or how the body uses them.

For example, magnesium oxide, citrate, and glycinate are different forms of magnesium. One form is not automatically better for everyone. The appropriate choice depends on the nutrient, dose, purpose, individual requirements, and scientific evidence.

5. Read the ingredient list

Check both active ingredients and other ingredients. Active ingredients provide the intended nutritional or physiological effect, while other ingredients may include fillers, binders, anti-caking agents, or sweeteners.

These ingredients are not necessarily bad; many serve important technological and manufacturing functions. What matters is transparency and appropriate formulation.

6. Be careful with impressive health claims

Claims such as “boosts immunity,” “detoxifies the body,” “burns fat,” or “reverses ageing” should prompt a closer look.

There is a difference between evidence from laboratory or animal studies, evidence that an ingredient affects a biological pathway, and strong clinical evidence in humans.

A scientifically interesting ingredient does not automatically mean that every supplement containing it will deliver the claimed benefit.

7. Check quality and regulatory information

Look for clear manufacturer details and regulatory information applicable in your country.

For products sold in India, consumers should pay attention to relevant FSSAI information, including manufacturer details, license information where applicable, and product category.

Transparent labelling and traceable manufacturing information are important indicators of a responsible product.

8. Check whether the dosage makes sense

More isn’t always better.

The appropriate dose depends on the nutrient or active compound, purpose, dietary intake, age, health status, and other factors. Be particularly careful when combining multivitamins, individual supplements, sports nutrition products, and fortified foods, as you may unintentionally exceed your total daily intake.

9. Don’t forget stability and storage

Heat, humidity, oxygen, light, and time can affect the stability of certain ingredients.

Follow storage instructions such as keeping the product in a cool, dry place, protecting it from moisture and sunlight, or refrigerating it where applicable.

Don’t just check the expiry date. Also check whether the packaging is intact and the product has been stored appropriately.

10. Ask: “Do I actually need it?”

A beautifully designed bottle, impressive ingredient list, or hundreds of positive reviews doesn’t necessarily mean you need the product.

If you have a medical condition, are pregnant or breastfeeding, take prescription medicines, or plan to combine multiple supplements, consult a qualified healthcare professional.
