Health and Sports Supplements: How to Choose Without Falling for Marketing Tricks

Between training powders, weight-management capsules and keto-friendly foods, the range of health and sports supplements can quickly become overwhelming. A colourful package, a dosage listed in milligrams or the word "natural" are not enough on their own to judge a product's suitability.

Here are the key criteria to check before you order, along with a selection of products suited to different needs.

Common Pitfalls Before You Buy

1. Confusing total weight with the actual active amount

A 1 kg tub doesn't necessarily contain 1 kg of amino acids. With BCAA powder, look at the amount actually provided per serving, the formula details and the number of servings available.

The same caution applies to a claim like forskoline 1000 mg: it may refer to the total weight of a concentrated extract, not 1,000 mg of pure forskoline. The concentration level and precise composition must be clearly stated on the label.

2. Mistaking "sugar-free" for "low in calories"

A sugar-free biscuit can still contain fats, flour or sweeteners. The nutritional table is therefore essential. Panpan biscuits, for example, contain 470 kcal per 100 g, despite the absence of added sucrose highlighted in their presentation.

Konjac shirataki noodles can have a place in a low-calorie diet, but they don't replace a source of protein, vitamins and minerals on their own.

3. Taking a marketing claim as a promise of results

A supplement is not a substitute for a balanced diet or a suitable programme. Claims like "weight loss", "post-workout recovery" or "joint support" should be taken with a pinch of salt. The effects you feel also depend on your diet, sleep, physical activity and consistency.

Information to Check on the Label

Daily dose and number of servings

Always compare:

  • the amount per dose;
  • the number of doses per pack;
  • the recommended daily dose;
  • the theoretical duration of use;
  • added ingredients, such as sweeteners, flavourings, vitamins or stimulants.

For amino acids aimed at athletes, BSN Amino X states 10 g of amino acids per 14.5 g serving, including L-leucine, L-isoleucine and L-valine. Some references also contain soya, an allergen to check before purchase.

Allergens and your dietary requirements

A vegan cannot rely solely on the word "natural". You need to check the origin of the ingredients, as well as the capsule shell. Marine collagen, for example, comes from fish and is not suitable for vegetarians or vegans.

On a keto or low carb diet, carefully examine the carbohydrate, sugar and excipient content. Konjac noodles are typically used as a low-carb accompaniment. A biscuit containing maltitol should be consumed taking into account the total carbohydrate content and the potentially laxative effect of polyols.

Compliance and usage precautions

In France and the European Union, the label must allow you to identify the serving size, ingredients, allergens, net quantity, storage conditions and usage precautions. Where information is provided, also check that a responsible party established in the European Union is clearly identified.

Never exceed the recommended dose. If you are on medication, pregnant or breastfeeding, have a chronic illness or need to follow a specific dietary restriction, seek advice from a healthcare professional before taking anything. Post-workout recovery is primarily based on good hydration, adequate nutrition, rest and a suitable training progression.

Frequently Asked Questions

Which supplement should I choose for post-workout recovery?

Start by assessing your protein intake, hydration and sleep quality. A BCAA powder can provide amino acids, but it doesn't replace a complete meal. The composition, serving sizes and allergens should carry more weight in your decision than the flavour or the shape of the tub.

Are konjac noodles suitable for a keto or low carb diet?

They are often used as a substitute for pasta as part of a low-carb diet. However, be sure to pair them with a source of protein, vegetables and a sauce whose composition you know. Remember to rinse and prepare them according to the instructions on the packaging.

How do I work out the real cost of a supplement?

Divide the price by the number of servings that actually correspond to the recommended dose. For tablets and capsules, calculate the cost per day. For a powder, check the weight of one dose and the number of servings possible. This way, you can compare a pot of 60 capsules, a 1 kg bag or a bottle of 180 tablets on the same basis.
