Whether you’re dealing with a temporary dip in energy, an unbalanced diet, sensitive digestion or difficulty sleeping, food supplements can address a wide range of needs. But an appealing label alone isn’t enough to help you make the right choice. Between one-size-fits-all promises, hard-to-compare dosages and ingredients that aren’t clearly listed, it’s easy to end up with a formula that doesn’t suit your expectations or lifestyle.
This guide helps you identify the information that really matters before you buy, then suggests options for different needs.
A product may list a large amount of powder, oil or extract without stating how much of the nutrient it actually provides. This is particularly true of omega-3: the total weight of fish oil doesn’t necessarily reflect the amount of EPA and DHA.
For fibre, also check the amount of dietary fibre per serving rather than relying on the total weight of the pack.
A formula claimed to support energy, immunity, skin, digestion and sleep may seem convenient. But it won’t necessarily meet your specific needs. Choose vitamins and minerals based on their ingredients, dosage and the nutrients already present in your diet.
Claims permitted in the European Union apply to specific nutrients and don’t guarantee the same effect for everyone. A supplement is no substitute for a varied diet or medical advice.
Vitamin K2, melatonin, herbal ingredients and high doses of magnesium all call for particular care. If you’re taking medication, are pregnant or breastfeeding, or have a chronic condition, speak to a healthcare professional before taking any supplements.
Look for the amount provided by the recommended daily dose. For magnesium, be sure to distinguish between the amount of magnesium salt and the amount of elemental magnesium. For example, the Nutri&Co formula provides up to 300 mg of elemental magnesium per three capsules, along with vitamin B6.
For vitamin D3 K2, check the number of micrograms per dose and the form of vitamin K2. The Nutrimexx spray lists 25 µg of vitamin D3 and 20 µg of vitamin K2 MK-7 per spray.
A transparent ingredients list should detail the ingredients, excipients, allergens and dosage form. Vegans and people with gluten intolerance may want to look for a plant-based capsule and clear information on the packaging, rather than relying on the product photo alone.
For omega-3, check whether the product contains fish, the total amount of EPA and DHA, the number of capsules per dose and the storage instructions. For probiotics, compare the strains and the number of colony-forming units listed per serving.
A product that’s easy to fit into your routine is less likely to be forgotten. Oils generally need to be stored away from heat and light. Dietary fibre and chia seeds should be taken with plenty of liquid. Melatonin can cause drowsiness, so avoid driving or operating machinery after taking it.
The format matters too: powders to mix, capsules, chewable tablets and sprays suit different habits.
Why this is a good fit for this profile : An all-in-one formula may suit adults who want to combine several vitamins and minerals in a simple routine, without accumulating lots of bottles.
The label lists 25 nutrients and specifies that it contains no iron or copper. The recommended dose is clearly set at three capsules a day.
Vegan, gluten-free formula with vitamins C, D3, E and K2, plus zinc and magnesium. The bottle contains 90 capsules.
Why this is a good fit for this profile : This format is for adults who want to know exactly how much omega-3 they’re taking and prefer a deodorised oil.
The product details list 1 050 mg of omega-3 per three capsules and provide access to an analysis via a QR code. The product contains fish and isn’t vegan.
Wild fish oil, vitamin E and fish gelatin capsules. The stated maximum dose is three capsules a day.
Why this is a good fit for this profile : This formula may suit adults and athletes looking for a targeted magnesium intake who are happy to spread their doses throughout the day.
The product details clearly distinguish elemental magnesium: up to 300 mg per three capsules. They also state the maximum dose and recommend spreading doses throughout the day.
Combines magnesium bisglycinate, malate and Magshape with vitamin B6. Vegan formula, with no gluten or gelatin.
Why this is a good fit for this profile : This unflavoured powder can be mixed into yoghurt, soup or a smoothie. It’s suitable for people who prefer to avoid capsules.
The product details list 8,3 g of fibre per 10 g serving and recommend starting gradually to help your digestion adjust.
Organic blend of agave inulin, acacia fibre and apple. According to the product details, it’s suitable for adults and children aged six and over.
We’ve put together a complete selection of products, updated in real time, that meet these rigorous criteria while complying with European safety regulations.
It depends on the product, the dose and your circumstances. Read the instructions and follow the recommended daily dose. If you’re planning to take vitamins, minerals or melatonin for an extended period, seek medical advice, particularly if you’re taking medication or are pregnant.
Unless the packaging says otherwise, store them in a cool, dry place away from light. Make sure powder pouches and bottles of capsules are properly sealed. Omega-3 oils need particular care to limit their exposure to heat and oxygen.
Sometimes, but combining several formulas can lead to excessive intakes of vitamin D, zinc, magnesium, vitamin B6 or other nutrients. Compare the labels before combining them, and speak to a healthcare professional if you’re taking medication or have a specific need related to hormonal balance, digestion or sleep.
