Persistent tiredness, an unbalanced diet, sporting activities or a preference for vegan formats: vitamin and mineral food supplements meet a wide range of needs. But an appealing label alone is not enough to make the right choice.
Before placing your order, three common pitfalls are worth avoiding:
The key is therefore to compare specific details: chemical form, quantity of nutrient, reference nutrient value, number of doses and compatibility with your lifestyle.
The most prominent figure on the packaging is not necessarily the one that matters to you. For magnesium, you need to distinguish elemental magnesium from the total weight of the citrate, bisglycinate or oxide. The same principle applies to potassium: the WeightWorld product provides 1 380 mg of potassium citrate per two tablets, equivalent to 500 mg of elemental potassium, which corresponds to 25% of the NRV.
The NRV, or reference nutrient value, helps put intake into context against European guidelines. It is a useful indicator when comparing different brands, but it is not personalised medical advice.
The form you choose mainly affects ease of use and individual tolerance. Magnesium citrate is available here as gelatin-free gummies with a grape flavour. Bisglycinate-, malate- and oxide-based formulas are generally available as capsules or tablets.
A box of 90 gummies can last 45 days if the recommended serving is two units per day. Conversely, 180 tablets may provide 90 days’ supply when taking two doses daily. When comparing offers, the cost per day is therefore more meaningful than the price displayed on the box.
Always follow the stated dosage, keep the bottle in a dry place and out of the reach of children. Pregnant or breastfeeding women, people taking medication and anyone with kidney problems should seek advice from a healthcare professional before taking a supplement. Potassium requires particular caution when taking medication or in cases of kidney problems. For zinc providing 15 mg of elemental zinc per gummy, equivalent to 150% of the NRV, the product information advises against prolonged use beyond three months without medical supervision.
The options below are intended for different uses. They are not a substitute for a varied diet and do not constitute medical advice.
Why this choice suits this profile : The chewable format is ideal for adults who forget to take their tablets or do not want to need a glass of water. The bottle provides 45 days’ supply at two gummies a day.
The product information specifies the amount of elemental magnesium : 160 mg per two gummies, rather than just the weight of the citrate. The sugar content is also stated.
A vegan, gelatin-free formula with a low sugar content and grape flavour. Magnesium is covered by authorised European claims relating to tiredness and the normal functioning of the nervous system.
Why this choice suits this profile : This vegan formula is aimed at people who prioritise a detailed composition and adjustable dosing of two to three capsules per day.
The product information distinguishes between three sources of magnesium and states that three capsules provide 300 mg of elemental magnesium. The maximum daily dosage is also clearly specified.
Plant-based capsules, a gluten- and GMO-free formula, vitamin B6 and packaging stated to be produced in France. The quantity per serving makes it easier to calculate the daily cost.
Why this choice suits this profile : This format is suitable for adults who want to add omega-3 to their routine and eat little fish.
The daily serving is clearly set at two capsules and provides 600 mg of EPA and 400 mg of DHA. This information is far more useful than simply stating ‘fish oil’.
120 capsules, simple to take with water, and separate EPA and DHA levels. Do not exceed the dose stated on the packaging.
For vitamin C, the Nutri&Co effervescent tablets provide 1 000 mg per tablet. They are sold in three tubes, providing 45 days’ supply at one tablet per day. The formula is described as vegan, lactose- and gluten-free, with no added sugar. However, you should take the presence of polyols into account: consuming them in excess may have a laxative effect.
Zinc may be suitable for people looking for a chewable format and a vegan formula. The WeightWorld product provides 15 mg of elemental zinc per gummy, with a red berry flavour. This relatively high level compared with the NRV means you should avoid combining it with other supplements that already contain zinc.
With potassium, caution is essential. The WeightWorld product combines 500 mg of elemental potassium with 80 mg of vitamin C per two tablets. This type of formula should not be chosen solely to support muscle function or electrolyte balance: your diet, medication and medical history should also be taken into account.
We have put together a complete, real-time updated selection of products that meet these demanding selection criteria and European safety requirements.
It all depends on the nutrient, dosage and directions stated on the label. Compare the number of servings available and avoid continuing a high-dose intake without professional advice. For the zinc product featured here, the product information specifically recommends not exceeding three months of continuous use without medical supervision.
They are easy to chew and do not require water, but they may contain sugar, sweeteners or polyols. Before buying, always check the daily serving, the amount of elemental nutrient and the full composition.
Sometimes, but combining them may result in unnecessary or even excessive intake, particularly of zinc, vitamin B6, magnesium or potassium. Add up the quantities contained in your different products and ask a pharmacist or doctor for advice if you are taking medication.
