Natural food supplements: how to choose a formula suited to your daily routine

Natural food supplements are popular thanks to their plant-based ingredients, convenient formats and promises relating to vitality, digestive comfort and weight management. But an attractive label alone is not enough to make the right choice.

French consumers regularly encounter three common pitfalls:

  • Confusing the weight of the plant with the amount that is actually active: a 40:1 concentrated extract cannot be interpreted in the same way as a simple plant powder.
  • Being persuaded by overly general claims: a food supplement is no substitute for a varied diet, physical activity or medical advice.
  • Underestimating the cost of use: a box of 180 capsules may last 90, 180 or just 60 days, depending on the recommended dosage.

When comparing wellness capsules, vegan food supplements or organic products, it is therefore best to look closely at the ingredients, daily dosage and length of use.

Criteria to check before buying

1. Understand the difference between powder, extract and standardised active ingredient

The figure shown on the front of the pack does not always correspond to the amount of active compound. For milk thistle, for example, it is more useful to check the stated silymarin content than to focus solely on the weight of the extract. The same applies to resveratrol and quercetin: standardisation of trans-resveratrol provides much more useful information than simply stating “antioxidant formula”.

Some useful guidelines:

  • Plant powder: the plant is generally ground into a powder, without any particular concentration.
  • Extract: a ratio such as 20:1 or 40:1 indicates a concentration obtained from a larger quantity of raw material.
  • Standardised active ingredient: the percentage of a compound — for example, 80% silymarin or 98% trans-resveratrol — makes it easier to compare different products.

This distinction also applies to products containing astaxanthin, alpha-lipoic acid, organic moringa, spirulina or chlorella.

2. Calculate the actual duration and price per day

A formula that seems affordable to buy may ultimately cost more if the daily dose requires you to take several capsules. Always check:

  1. The total number of capsules.
  2. The recommended daily serving.
  3. The number of days of use.
  4. The quantity of active ingredient per serving.

For example, a box of 240 capsules taken at a rate of three capsules per day corresponds to 80 days of use. This calculation is particularly useful when comparing a weight-loss food supplement, plant-based omega products made from hemp seed oil or complexes intended for long-term use.

3. Check criteria related to your diet

Claims such as vegan, gluten-free, lactose-free, GMO-free or organic should not be inferred from the product name. Look for them in the detailed product information and check the ingredients list.

When it comes to algae, Irish moss — often called “Irish sea moss” — may be combined with bladderwrack, which naturally provides iodine. If you are taking medication or have a particular medical condition, ask a healthcare professional for advice before taking any supplement. The same caution applies to formulas containing caffeine, organic fenugreek, shilajit or several plant extracts.

Frequently asked questions about natural food supplements

How long should you take a natural food supplement?

It all depends on the formula, the stated dosage and your objective. Some boxes cover 30 days, while others last several months. Follow the recommended serving on the packaging, and do not continue taking the supplement without professional advice if you are undergoing treatment or have a particular medical condition.

Are vegan food supplements automatically organic?

No. Vegan means that the product contains no animal-derived ingredients, while organic refers to specific standards and certification. A formula can therefore be vegan without being organic, or it can have both characteristics. Check the logos and information shown on the product page.

Can a food supplement replace a diet for weight loss?

No. A weight-loss food supplement is no substitute for a balanced diet or suitable physical activity. Formulas containing caffeine, green tea, raspberry ketone or forskolin require careful attention to the usage precautions. If in doubt, ask a healthcare professional for advice.
