Mercadona has added a creatine supplement for customers focused on sports and physical performance. The 200-gram tub, made by Ynsadiet, is available in select supermarkets and through the retailer’s online platform for €8. Each 4.2-gram serving is stated to provide 3 grams of creatine, the daily amount associated with the European Union’s authorized claim on physical performance during successive bursts of short-term, high-intensity exercise. The claim is specific to that type of exertion, not a general promise of improved athletic performance.
The product has a neutral flavor and comes with a measuring scoop, making it easy to mix with beverages such as water or milk. At the recommended daily dose of 4.2 grams, a 200-gram tub provides about 47 servings, roughly a month and a half of daily use. That works out to approximately 17 cents per serving. The claimed serving size and active-creatine amount are different measures: the 3 grams refers to creatine, while 4.2 grams is the total powder dose.
Composition and Market Context
Unlike a product made solely from creatine monohydrate, Mercadona’s formula combines creatine monohydrate, creatine phosphate and calcium salts of orthophosphoric acid. The label states that each 4.2-gram serving contains 3 grams of creatine, 137 mg of phosphorus and 161 mg of calcium. Creatine so represents about 71% of the serving by weight. Applying that proportion to the 200-gram tub gives an estimated 143 grams of declared creatine; that calculation describes the stated composition, not a laboratory measure of purity or proof of uniformity throughout the blend.
Creatine monohydrate is the most commonly used format, information from Decathlon España. That makes the distinction between a monohydrate product and a multi-form blend relevant when comparing tubs. A like-for-like price comparison should consider the amount of declared creatine rather than package weight alone, along with the product’s chemical form and serving size. At the stated €8 price and composition, the estimated cost is about €5.60 per 100 grams of declared creatine. This provides a basis for comparison, though prices also depend on pack size, delivery or store costs, and the composition of competing products.
What Creatine Does and What It Doesn’t
Creatine is a naturally occurring compound produced by the body and also found in foods such as meat and fish. About 95% of the body’s creatine is stored in skeletal muscle, where it contributes to rapid energy metabolism during short, intense efforts. The EU-authorized health claim is narrowly defined: creatine increases physical performance in successive bursts of short-term, high-intensity exercise, with the beneficial effect associated with a daily intake of 3 grams. It is not a general claim about endurance, all forms of exercise or athletic performance as a whole.
Creatine is not authorized as a remedy for general fatigue, lack of sleep or illness-related tiredness. Its recognized performance claim relates to particular forms of intense physical exertion, not to low energy more broadly.
Manufacturer and Ongoing Debate
The supplement is produced by Laboratorios Ynsadiet, a Madrid-based company with more than four decades of experience in dietary supplements and natural cosmetics. Its blend of creatine forms, rather than monohydrate alone, has prompted discussion among consumers and fitness professionals. The comparison turns in part on what shoppers value: monohydrate is the most commonly used format, while this product combines several creatine-related ingredients and declares 3 grams of creatine per serving.
For those comparing options, the declared creatine content offers a more informative measure than total package weight alone. The same kind of practical scrutiny applies in other consumer markets: hidden value in home renovations can surprise even experienced professionals, as illustrated by a recent story about a Madrid plumber who profited from recycling copper pipes during a renovation (unexpected gains from home upgrades).
Usage Guidelines and Safety
Mercadona and Ynsadiet both emphasize that users should not exceed the recommended daily dose. The supplement is not intended to replace a balanced diet, should be kept out of reach of children and is not recommended during pregnancy. The Spanish Agency for Food Safety and Nutrition (AESAN) considers a maximum daily intake of 3 grams safe for healthy adults. There is insufficient data on use in children, and people with pre-existing kidney conditions should exercise caution.
Mercadona’s move brings a once-niche supplement to a wider market. Consumers can compare the product’s 4.2-gram serving size with its declared 3 grams of creatine, and consider their own health needs when deciding whether to add it to their routines.
