How to Read a Supplement Label: What Every Woman Should Look For

Walk into any health food shop or search online for supplements and you'll quickly discover there is no shortage of choice. Bright packaging, impressive sounding ingredients and bold health claims can make it difficult to know which products are genuinely well formulated and which are driven more by marketing than science.

A supplement label should tell you far more than what flavour it is or how many servings are inside. It offers valuable insight into the quality of the product, the ingredients it contains and whether it is likely to support your health in a meaningful way.

Understanding what to look for can help you make more informed choices and avoid spending money on products that may offer little benefit.

Here is some practical guidance to help you understand the label in front of you. 

1. Turn the packet over first

The front of a supplement is designed to sell you the product. The real information is found in the ingredients list and nutrition panel.

Of course, many of us now buy supplements online rather than standing in a shop with the packet in our hands. The same rule still applies. Before you buy, look for the equivalent information on the product page. A reputable brand should make the full formulation, ingredient amounts and nutritional information easy to find.

Before I look at any health claims, I go straight to the ingredients list and nutrition panel. That is where you will find the dose of each ingredient, the form it is in and exactly what else has been added.

Practical tip: Before you buy any supplement, ignore the front completely. Turn it over and ask yourself:

• Can I see the amount of every active ingredient?
• Is there a % NRV column for the vitamins and minerals?
• Do I recognise most of the ingredients?

If the label isn't transparent, it's difficult to judge the quality of what's inside.

2. Look at the dose, not just the ingredient

Many supplements advertise fashionable ingredients on the front of the packet, but when you read the label you may find they're only included in tiny amounts.

Research is based on specific doses, not simply on the presence of an ingredient. If the amount is too low, it's unlikely to provide the same benefit seen in studies.

Practical tip: If an ingredient is highlighted on the front of the pack, make sure the amount is clearly listed on the back. Be cautious of "proprietary blends" that combine several ingredients without telling you how much of each you're actually getting.

3. Check the % NRV

The Nutrient Reference Value (NRV) tells you what percentage of your daily requirement each vitamin or mineral provides.

Many people assume more is better, but that's not always the case. Some supplements contain several hundred or even several thousand percent of the NRV for certain nutrients. Others contain so little that they make very little nutritional contribution.

For most people looking for a daily nutritional foundation, around 100% of the NRV for key vitamins and minerals is often a sensible place to start.

Practical tip: Find the "% NRV" column on the label. If most nutrients are around 100%, that's generally appropriate for everyday use. If you see very high percentages, ask yourself whether there's a reason for those larger doses, especially if you're taking other supplements too.

4. Look at the form, not just the name

Not all nutrients are the same.

The form they're provided in can influence how well they're absorbed and how well they're tolerated.

For example:

• Magnesium glycinate or citrate are generally better absorbed than magnesium oxide.
• Iron bisglycinate is often gentler on the digestive system than ferrous sulphate.
• Calcium citrate malate is generally more bioavailable than calcium carbonate.

Practical tip: Don't stop reading after "magnesium" or "iron". Read the full name. The word after the nutrient often tells you far more about its quality.

5. Think about the formulation as a whole

Your body doesn't use nutrients in isolation. Protein, vitamins, minerals, fibre and plant compounds all work together.

Rather than looking for one "miracle ingredient", ask whether the product has been designed to provide a balanced nutritional foundation.

Practical tip: If the product is built around one fashionable ingredient but provides little else, it may not be the most useful option. Look for a formulation where each ingredient has a clear purpose.

6. Check the protein source

If you're choosing a nutritional blend rather than a traditional tablet, don't just look at how much protein it contains. Look at where that protein comes from.

As we age, protein becomes increasingly important for maintaining muscle and supporting healthy bones.

Practical tip: Check the ingredients list. Does the protein come from recognised sources such as pea or rice protein? Is it providing a meaningful amount per serving? If you avoid soy, this is also the place to check whether it's included.

7. Know what fillers look like

Every supplement contains some inactive ingredients to help with manufacturing, but they shouldn't dominate the label.

Common fillers include ingredients such as maltodextrin, artificial colours, artificial sweeteners and unnecessary bulking agents. Some manufacturing ingredients, such as silicon dioxide or magnesium stearate, are commonly used in small amounts and aren't necessarily a sign of a poor-quality product. The key is looking at the overall formulation rather than one ingredient in isolation.

Practical tip: Read the ingredients list from top to bottom. If the active ingredients are followed by a long list of additives you don't recognise, ask why they're there. A good formulation should focus on delivering nutrients rather than unnecessary extras.

8. Don't be afraid of botanicals

Ingredients such as ashwagandha often make headlines, but context matters.

Most botanicals have been studied within a particular dose range. Using too little may have little effect, while using unnecessarily high amounts isn't always better.

Practical tip: Check whether the botanical has its dose clearly listed. If it doesn't, or if it's hidden inside a proprietary blend, you can't judge whether the amount reflects the evidence.

9. Avoid doubling up

It's surprisingly easy to take the same nutrients several times a day without realising it.

A multivitamin, vitamin D, magnesium, collagen, protein powder and a menopause supplement may all contain overlapping vitamins and minerals.

Practical tip: Before buying a new supplement, compare it with the ones you already take. Look for repeated nutrients and add up the amounts. Sometimes one well-formulated product can replace three or four separate supplements.

 

What we believe at Her Vital Blend

When I formulated Her Vital Blend, the aim was never to create the biggest ingredient list or the highest doses.

The goal was to develop a daily nutritional blend that women could use consistently as part of a healthy lifestyle.

That means focusing on meaningful nutrition rather than marketing hype.

Our formulation includes:

• 20g of high quality plant protein in every serving
• Over 15 vitamins and minerals, each provided at around 100% of the NRV to support everyday nutritional needs.
• Clinically considered amounts of carefully selected botanical ingredients, including ashwagandha, maca and dandelion root.
• Fibre and gut supportive ingredients.
• No soy.
• No genetically modified ingredients.
• No unnecessary fillers.
• Bioavailable forms of vitamins and minerals.
• A clean, vegan formulation designed for everyday use.

Every ingredient has been included for a reason, with the overall formulation considered just as carefully as each individual nutrient. Meaning it really has everything you need, and nothing you don't. You can find out more about our nutritional blend for women in midlife here. 

Remember, supplements are exactly that

Even the highest quality supplement cannot replace the foundations of good health.

A balanced diet, adequate protein, regular movement, quality sleep, stress management and time outdoors remain the cornerstones of healthy ageing.

Supplements are there to complement those habits, not replace them.
