Vitamin and mineral supplements: how to choose a formula suited to your needs

With multivitamins, gummies, tablets and liquid formulas to choose from, comparing vitamin and mineral supplements can quickly become difficult. A formula designed for women will not necessarily meet the needs of a man, a 50-year-old senior or a child aged 4 and over. Dosage, format and directions for use matter at least as much as the number of nutrients shown on the label.

Common pitfalls before buying

1. Mistaking a long ingredient list for a suitable formula

A product listing 20 or 30 vitamins and minerals is not automatically right for your diet. Check the quantities given per daily dose and compare them with the NRVs, the Nutrient Reference Values used in the European Union. A formula may contain many different nutrients, some of which are present at very low doses.

2. Overlooking the sugar and additives in gummies

Gummies are easy to take, but they often contain glucose syrup, sugar or a sweetener. Check the amount of sugar per serving, especially if the product is taken every day. Their texture can also be affected by heat and humidity : it is best to store them in a dry, closed cupboard at a moderate temperature.

3. Choosing a high dosage without checking whether it suits you

A high dosage is not necessarily suitable for everyday use. This is particularly true of high-strength vitamin D3 K2, iron and biotin. Anyone taking medication, pregnant or breastfeeding women, children and people with a specific health condition should seek advice from a healthcare professional before use.

Essential criteria for comparing formulas

Composition and dosage per serving

Start by identifying your main need :

  • Multivitamins : a broad supply of vitamins and minerals to supplement a varied diet, not replace it.
  • Vitamin C and zinc : a targeted formula, available as gummies or tablets, whose dosages should be compared carefully.
  • B-vitamin complex : an interesting option for anyone looking for a formula combining vitamins B1, B2, B3, B5, B6, B7, B9 and B12.
  • Biotin for hair, skin and nails : check for biotin, zinc or selenium, as well as the actual quantities provided.
  • Iron with vitamin C : iron should not be taken at random, particularly by children. The label should specify its form and the dose per unit.

Nutrition and health claims authorised in Europe should be understood as indications governed by regulations, rather than as a promise of individual results. For example, vitamin C contributes to the absorption of iron under the conditions set out in European regulations.

Format : tablet, gummy or liquid

A tablet is suitable for people looking for a long shelf life and precise dosage. A gummy makes it easy to take without water, but you should monitor its sugar content and follow the recommended daily dose. A liquid food supplement is practical for people who find tablets difficult to swallow. However, it requires accurate measuring with the supplied cup and often needs to be refrigerated after opening.

Dietary requirements and age

Claims such as vegan, gluten-free or lactose-free should be checked against the ingredients list and allergen information. For children, only choose a formula that clearly states the minimum age and suitable dose. A product intended for adults, even if presented as a gummy, is not automatically suitable for a child.

Checks before ordering

  • Read the recommended daily dose and do not combine several similar products without calculating the total intake.
  • Check for allergens, sugar, caffeine, gluten or ingredients of animal origin, depending on your dietary requirements.
  • For vitamins intended for women, those intended for men and 50+ multivitamins, compare the amounts of iron, vitamin D, calcium, magnesium, zinc and B vitamins.
  • For a biotin formula for hair, skin and nails, be aware that biotin can affect the results of some blood tests : tell your doctor or the laboratory that you are taking it.
  • Keep products out of the reach of children and follow the best-before date shown on the packaging.

FAQ about vitamin and mineral supplements

Can you take several supplements at the same time ?

This is possible in some cases, but duplicate ingredients are common when combining a multivitamin with a vitamin C and zinc supplement, vitamin D3 K2 or a B-vitamin complex. Compare the total doses and seek advice from a healthcare professional if you are taking medication or have specific needs.

How long can a food supplement be stored ?

Shelf life depends on the format and storage conditions. Tablets and gummies can generally be kept in a cool, dry place. After opening, a liquid supplement may need to be refrigerated and consumed within the period stated by the manufacturer.

Are vitamin gummies suitable for all children ?

No. Check the minimum age, dosage and supervision instructions. A gummy intended for children aged 4 and over is not a substitute for medical advice and must not be left within reach : its appearance can easily be mistaken for that of a sweet.
