How To Read A Supplement Label

Why Supplement Labels Matter

When choosing a food supplement, most people focus on the front of the package.

The product name, flavour, serving size and marketing messages are often the first things consumers notice.

However, the most important information is usually found on the back label.

Understanding how to read a supplement label can help consumers compare products more effectively and make more informed purchasing decisions.

This guide explains the key sections commonly found on food supplement labels and what information they provide.

1. Check The Active Ingredients

The active ingredients are usually the most important part of any supplement.

They tell you what the product contains and how much is provided per serving.

Examples include:

Creatine Monohydrate
Magnesium
Fish Oil
Vitamin D3
Vitamin K2
Lion's Mane Extract
Ashwagandha Extract
Whey Protein

Different products may contain similar ingredients but in different forms or amounts.

Reviewing the active ingredient section can help consumers understand exactly what is included in a product.

2. Look At The Serving Size

The amount of an ingredient listed on a label is usually based on a specific serving size.

Examples include:

1 tablet
2 capsules
2 gummies
1 drop
30 g powder serving

When comparing products, it is important to compare the amount of active ingredients per serving rather than only comparing package size.

A larger container does not always mean a higher amount of active ingredients per serving.

3. Understand Nutritional Reference Values (NRVs)

Many vitamins and minerals include a percentage value known as the Nutrient Reference Value (NRV).

NRVs are reference values established under European legislation and help consumers understand how much of a nutrient is provided by a serving.

Examples:

Vitamin D3 – 500% NRV
Vitamin B6 – 100% NRV
Magnesium – 66.7% NRV

The NRV percentage indicates how much of the daily reference intake is supplied by the recommended serving.

4. Review The Ingredients List

The ingredients list provides information about everything included in a product.

In addition to active ingredients, it may include:

capsule shells
sweeteners
flavourings
colourings
stabilisers
anti-caking agents

Ingredients are generally listed in descending order by weight.

Reviewing the ingredients list can help consumers better understand the overall composition of a supplement.

5. Check For Allergens

Food supplements may contain allergens or traces of allergens.

Examples commonly found in supplements include:

Milk
Fish
Soy
Sulphites
Peanuts

Individuals with food allergies or sensitivities should always review allergen information carefully before use.

Allergen declarations are typically highlighted on the product label.

6. Understand Sweeteners And Colourings

Many powders, gummies and flavoured supplements contain sweeteners or colourings.

Examples of sweeteners include:

Sucralose
Steviol Glycosides
Erythritol
Maltitol

Examples of colourings include:

Beetroot
Beta-Carotene
Anthocyanins
Turmeric
Riboflavin
Ponceau 4R (E124)
Carmoisine (E122)

Consumers can review ingredient lists to identify which sweeteners and colourings are used in a product.

7. Look At The Recommended Daily Serving

Every supplement label includes a recommended daily serving.

This section explains:

how much to take
how often to take it
how to prepare the product if required

Examples include:

1 capsule daily
2 gummies daily
1 drop daily
30 g mixed with water

Consumers should always follow the serving instructions provided on the label.

8. Read The Warnings And Storage Information

Food supplement labels also include important safety information.

Common examples include:

Do not exceed the recommended daily dose.
Keep out of reach of children.
Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.

Storage instructions may also be provided, such as:

Store in a cool, dry place.
Protect from direct sunlight.
Consume within a specified period after opening.

9. Look For Manufacturing And Quality Information

Many supplement labels include information relating to manufacturing standards and quality control.

Examples may include:

GMP manufacturing
HACCP systems
ISO-certified facilities
Laboratory testing
Third-party testing

Consumers may wish to review this information when comparing products.

10. Understand The Product Format

Food supplements are available in a variety of formats.

Examples include:

Capsules

Convenient and easy to transport.

Tablets

Commonly used for vitamins and minerals.

Gummies

Chewable format that does not require water.

Powders

Can be mixed with water or other beverages.

Liquid Drops

Provide a liquid alternative to capsules and tablets.

Different consumers may prefer different formats depending on personal preference and lifestyle.
