Sports supplements: how to choose the right formula for your goals

With promises of instant performance gains, dosages that are difficult to compare and ever-growing ingredient lists, buying sports supplements can quickly become expensive. Creatine, BCAAs, beta-alanine, taurine and L-citrulline do not meet the same needs. The most suitable choice mainly depends on your sport, diet, training frequency and the format you are genuinely prepared to take every day.

Pitfalls to avoid before buying

1. Relying solely on the ingredient name

Seeing ‘creatine’ or ‘BCAA’ on the label is not enough. You also need to check the amount per serving, the form used and the number of servings required. Two products may highlight the same ingredient while providing very different amounts.

For example, one supplement may state 3.4 g of creatine monohydrate, providing 3 g of creatine, while another may list 3 g of creatine monohydrate directly per serving. To compare products properly, it is therefore better to examine the composition in detail rather than focusing only on the name displayed on the front.

2. Confusing a complete formula with an overloaded one

A pre-workout combining caffeine, guarana, taurine, beta-alanine, vitamins and plant extracts may seem particularly versatile. However, the longer the list, the harder it becomes to know the exact amount of each active ingredient and track your total caffeine intake throughout the day.

If you train in the evening, a stimulant-free formula will often be easier to fit into your routine. People who are sensitive to caffeine should carefully monitor the recommended servings and read the warnings on the packaging.

3. Overlooking the format and your diet

Powder requires a glass, a scoop and mixing. Tablets are easy to carry, but some formulas require you to take several each day. Gummies are pleasant and convenient, but they may contain sweeteners and have a different cost per serving.

If you are looking for vegan supplements or gluten-free options, also check the ingredient list, the capsule composition and any statements concerning traces. A formula described as plant-based does not automatically guarantee the absence of all allergens.

Criteria to compare before choosing

The amount you will actually consume

The WeightWorld product featured here provides 3 g of creatine monohydrate per daily serving. This amount corresponds to the authorised European Union claim regarding increased physical performance during successive bursts of short, high-intensity exercise, when consuming 3 g of creatine daily.

Dosages can vary considerably from one amino acid to another. The WeightWorld BCAA product provides 2 000 mg per serving of two tablets, in a 2:1:1 ratio. The Body & Fit BCAA Amino product, meanwhile, states 8 g of BCAAs per serving, but this serving consists of 15 g of powder and also contains other ingredients. These details make it easier to estimate the true cost of each serving.

The composition and excipients

A short formula is easier to read and follow. For creatine, look for the precise wording creatine monohydrate and check whether the product contains flavourings, sweeteners or texturing agents. For L-citrulline or L-arginine, make sure the stated dosage corresponds to the full daily serving.

Beta-alanine can cause a tingling sensation in some people. This feeling is not an indicator of performance. The safest approach is to follow the recommendations on the label and avoid combining several products containing the same ingredient.

Compatibility with your training

  • Muscular strength and short sets : creatine monohydrate is often chosen for consistent daily use.
  • Endurance and extended sessions : beta-alanine, taurine and L-citrulline are found in various formulas, but their uses and dosages are not interchangeable.
  • Muscle recovery : BCAAs, glycine or HMB can complement an already structured diet. They do not replace protein, carbohydrates, good hydration or, least of all, sleep.
  • Pre-workout : add up the caffeine from all sources, particularly when the product combines anhydrous caffeine, guarana and plant extracts.

Food supplements should not be used as a substitute for a varied, balanced diet. If you are taking medication, have a health condition, are pregnant or breastfeeding, seek advice from a healthcare professional before use.

Frequently asked questions about sports supplements

How long should a creatine course last ?

Creatine is generally taken every day, following the dosage specified by the manufacturer. The length of use depends on the format chosen : at a dose of 3 g, a 1 kg pouch provides a considerably longer theoretical supply than a 247.5 g tub. Always check the scoop provided and the serving stated on the label.

Are BCAAs essential for muscle recovery ?

BCAAs provide leucine, isoleucine and valine. Their value depends on your diet as a whole and the amount of protein you already consume. They do not replace a complete meal or a protein source suited to your needs.

How can you choose a pre-workout without exceeding the recommended caffeine intake ?

Add up the caffeine provided by the supplement, coffee, tea and energy drinks. The Amok product, for example, contains anhydrous caffeine and guarana, and comes with specific precautions. Check the amount per capsule, follow the instructions and avoid stimulant formulas if you train shortly before going to bed.
