Whey protein, electrolytes, protein bars and pre-workout formulas: the sports nutrition aisle is packed with options, but they do not all meet the same needs. A long-distance runner will not be looking for the same products as someone who does weight training or enjoys combat sports.
The most common pitfall? Buying based on a slogan rather than checking the ingredients. Here are the criteria to consider to avoid unnecessary spending and choose sports supplements suited to your activity and everyday life in France.
Claims such as “performance”, “fast recovery” or “long-lasting energy” are not enough on their own to distinguish between two products. To make an informed choice, compare the amount per serving, the ingredients list and the nutrition table. A protein powder may be sold in a large bag while providing relatively little protein per serving.
A classic energy drink can contain 27.5 g of sugar per 25 cl can, such as Red Bull Regular. Conversely, some bars with no added sugar rely on maltitol or other polyols, which can cause digestive problems for some people when consumed in large quantities.
Pre-workout supplements also deserve careful consideration. Caffeine, guarana and other plant extracts can quickly increase the total amount of stimulants consumed throughout the day.
A large bag of whey often offers a more attractive price per serving, but it takes up more space and needs to be stored carefully. By contrast, effervescent tablets and individual sachets are easy to slip into a gym bag and are practical at work, when travelling or for an outdoor session.
For whey protein, compare the amount of protein per serving first, rather than just the total weight of the bag. Several products in this selection state that they provide around 22 to 24 g of protein per serving, with varying amounts of carbohydrates, fat and sugar.
For protein bars, also look at the balance between protein, calories and carbohydrates. A bar can certainly work as a snack, but it does not replace a complete and varied meal.
Hydration electrolytes include sodium, potassium, calcium, magnesium and chloride. Their usefulness depends on the duration of your activity, how much you sweat and the weather conditions. For example, one Nutri&Co tablet provides 300 mg of sodium and 300 mg of potassium, as well as calcium, magnesium, chloride and zinc.
Always stick to the recommended dosage. Products containing potassium require particular caution in cases of kidney impairment or kidney disease. If you are taking medication or have a health condition, seek advice from a healthcare professional before using them.
Take the time to read the full ingredients list: several whey products contain milk and soya, some bars contain peanuts, while recipes based on oats or barley may contain gluten. Some capsules also use gelatine. Claims such as “no added sugar” or “free from allergens” never remove the need to check the labelling of the product you choose.
Amino acids, such as L-arginine and L-citrulline, should also be compared based on the stated daily dose. One WeightWorld product lists 3,000 mg of L-citrulline for four capsules, while an L-arginine product provides 4,000 mg for four tablets. This information indicates the composition, but does not guarantee the same effect for everyone.

Whey can be mixed with water or milk and consumed after training, between meals or at any other time of day. The best timing mainly depends on your overall diet and routine. Follow the serving size stated on the packaging and do not turn shakes into substitutes for a varied diet.
Not necessarily. For a short, moderate-intensity session, water is enough for many people. Electrolytes may be useful during prolonged exercise, in hot weather or when you sweat heavily. Always check the amounts of sodium and potassium, particularly if you have a kidney condition or are taking medication.
Refer to the date shown on the packaging and the manufacturer’s storage instructions. Whey generally keeps well when tightly sealed, stored in a dry place away from heat. Energy and protein bars should also be kept in a dry place at the recommended temperature. After opening, reseal pouches and tubes carefully to prevent moisture from getting in.
