Sports supplements: how to choose according to your goals and budget

Protein powder, whey, protein bars and weight-management supplements: there is no shortage of sports nutrition products. The problem is that marketing claims do not always make it easy to compare products on a sound basis. To avoid unnecessary purchases, focus on three things: the ingredients, the portion you actually consume and the product’s place in your diet.

Common pitfalls before buying

1. Confusing the weight of the powder with the amount of protein

A 500 g pouch does not necessarily contain 500 g of protein. It all depends on the recipe. Whey generally provides between 74 and 79 g of protein per 100 g, while a protein bar most often provides 10 to 20 g per bar.

The best approach is to check the nutrition table per 100 g and per serving. This dual comparison makes it easier to assess a powder, bar or protein snack accurately, without being swayed by the packaging weight alone.

2. Relying on claims such as “fat burner” or “weight management”

Supplements marketed as fat burners — whether they contain caffeine, raspberry ketones, forskolin or CLA — are no substitute for a varied diet or regular physical activity. A label may state a precise quantity of ingredients without guaranteeing results for every user.

Check for any stimulants, the recommended daily dose and the warnings. If you are taking medication, are pregnant or breastfeeding, or have a health condition, seek advice from a healthcare professional before taking any supplement.

3. Overlooking allergens and polyols

Whey protein is generally made from milk. Some bars also contain soya, peanuts, nuts or collagen. Meanwhile, “no added sugar” recipes may use polyols such as maltitol, which can sometimes be difficult to digest when consumed in large quantities.

The ingredients list is therefore essential, even when the product is only consumed occasionally.

Criteria to check to make the right choice

Protein content per serving

After a weight-training or fitness session, compare the amount of protein the product actually provides. As a guide, the products featured here provide around 22 to 24 g per serving of powder, compared with 14 to 20 g per bar.

As part of a suitable diet and resistance-training programme, protein contributes to the maintenance and development of muscle mass. However, it cannot make up for insufficient calorie intake, a lack of sleep or a poorly structured training programme.

Protein source

  • Whey protein: made from milk, it can be mixed with water or milk and is suitable for people who consume dairy products.
  • Plant protein: pea and rice blends may suit vegetarian and vegan diets. However, always check for possible traces of milk, soya or gluten.
  • Protein bar or snack: convenient to take with you, but often higher in fat, fibre, polyols or sugar than a powder.
  • Medical nutrition products: certain products intended for nutritional support should be used in accordance with the instructions on the packaging and, where necessary, under medical supervision.

Calories, carbohydrates and fats

A powder providing 22 to 24 g of protein for around 113 to 128 kcal can easily fit into a snack. A bar containing 189 or 220 kcal is more like a complete snack. If you are watching your weight, always compare your total daily intake: a product labelled “high-protein” can still be high in calories.

Texture and ease of preparation also matter in everyday life. A serving mixed with 180 to 300 ml of water will be more convenient after training than a product requiring several ingredients and a longer preparation time.

FAQ about sports supplements

When should you take whey protein?

Whey can be consumed after training, at breakfast or between meals, depending on your needs. The exact timing matters less than your total daily intake, the consistency of your training sessions and the overall balance of your diet. Follow the serving recommendation on the packaging.

Can a protein bar replace a meal?

Not necessarily. A bar can be a convenient option when you are travelling or after a workout. However, check its calorie, fibre, fat, sugar and polyol content. It may not contain all the nutrients you would expect from a complete meal.

How long can you keep powder or a protein snack?

Follow the date shown on the packaging and the recommended storage conditions. Seal pouches and tubs of powder carefully, then store them in a cool, dry place away from light. Bars are generally best kept at room temperature, away from moisture and heat. Once opened, follow the manufacturer’s specific instructions.
