When we started formulating creatine, we faced a fundamental question: why not follow the traditional model? Why not another jar of white powder, as hundreds of brands do?
The answer involves science, European regulations, consumer psychology, and our core philosophy — Zero Pills.
This article explains the scientific, practical, and philosophical reasons behind the decision to integrate 3.5g of creatine monohydrate directly into a bar — instead of another jar on the bathroom shelf.
1. The real problem isn't creatine — it's adherence
Creatine monohydrate is one of the most studied molecules in sports nutrition. Its effectiveness is documented in hundreds of clinical trials. Its safety is confirmed by ISSN for over 10 years of continuous use. There's no doubt it works.
The problem is elsewhere: 50% of people who buy creatine powder stop using it within 3 months. Not because it doesn't work. Because measuring powder every day, mixing it in a shaker, remembering to do it before or after training — is boring. And boring things are abandoned.
The uncomfortable truth: A supplement with a theoretically perfect dose, which no one takes consistently, has zero effectiveness. A food with a slightly lower dose, which you eat every day because you feel like it, has real effectiveness.
2. Why a bar — and not a jar of powder
3. The dose — 3.5g per bar
The dose in CORIAL Creatine Bars is 3.5g of creatine monohydrate per 50g bar. It's a deliberate choice, not a limitation.
The ISSN recommends 3–5g/day for continuous maintenance effects. The minimum effective threshold recognized by EFSA for the approved claim is 3g/day. 3.5g per bar is above the minimum effective threshold — and within the optimal dose window for continuous daily use.
Would it be possible to make a bar with 5g? Yes. But in a 50g bar, increasing creatine to 5g squeezes the space for other ingredients that make the bar a real food — pea protein isolate, dates, almonds, chicory fiber. We opted for a balanced composition. For those who train with high volume and need 5g or more, the combination of 1 bar + powder supplement is the ideal hybrid approach.
4. The EFSA claim — what we can and cannot say
"Creatine increases physical performance in successive bursts of short-term, high-intensity exercise."
This is the only health claim for creatine approved by the European Food Safety Authority. The effect is obtained with 3g of creatine per day. Each CORIAL Creatine Bar provides 3.5g — above the minimum threshold.
We do not communicate that creatine "increases strength," "builds muscle," or has cognitive effects — because these claims are not approved. EFSA requires specific evidence for each claim. When science reaches that point, legislation may evolve. Until then, we only communicate what is approved.

6. Honest comparison: bar vs. powder
| Criterion | Traditional Powder | CORIAL Creatine Bar |
|---|---|---|
| Creatine per dose | 3–5g (adjustable) | 3.5g (fixed per bar) |
| Absorption | Excellent in water | Excellent with carbohydrates |
| Texture/Taste | Tasteless, gritty in water | Flavored snack — Creamy Coconut or Fudge Brownie |
| Preparation | Measure + mix + shaker | Zero — open and eat |
| Portability | Jar + spoon + liquid | Bar in pocket — nothing else |
| Adherence (3 months) | ~50% continue | ~85–90% continue |
| Loading phase (20g/day) | Yes — easy and economical | Impractical — 5+ bars/day |
| Cost per gram of creatine | €0.03–0.05/g (cheaper) | Integrated into the price of the complete snack |
| Additional nutrition | None | Protein (7–8g), fiber, healthy fats |
| Stability | 6–12 months dry | 18+ months with sealed packaging |
When powder makes more sense than the bar: if you need a loading phase (20g/day for 5–7 days), if the cost per gram of creatine is the decisive factor, or if you already have a perfectly maintained supplementation routine — powder is the most economically efficient choice. There's absolutely no problem with that. CORIAL recognizes that the bar is not for everyone — only for those who value convenience and integration into food.
7. The three scientific pillars of the decision
Kreider et al. (2017) demonstrated that 3–5g of creatine monohydrate daily increases intramuscular creatine content by 20–40%, with measurable improvements in maximal strength and power in strength athletes. The 3.5g dose reaches steady state in 3–4 weeks of continuous use.[1]
Green et al. (1996) showed that co-ingestion of creatine with simple carbohydrates increases intramuscular retention by up to 60% compared to isolated creatine in pure water. The dates present in each CORIAL bar provide this optimized absorption environment — without extra steps.[2]
Research in behavioral nutrition shows that foods integrated into daily routines have 3–5× greater long-term adherence than isolated supplements. 3.5g taken every day for 90 days always outperforms 5g taken 50 days and forgotten for the remaining 40.[3,4]
8. FAQ
CORIAL Creatine Bars — the decision was deliberate
99.99% Creatine monohydrate integrated into a bar with protein, prebiotic fiber, and natural ingredients. Two flavors. A guaranteed daily dose — without thinking.
