Bunte Dosen, leere Versprechen: Top 5 vs. Flop 5 Supplements

Zwischen Wissenschaft und Marketing

Nahrungsergänzungsmittel gehören längst nicht mehr nur zum Alltag von Sportlern. Ob Muskelaufbau, Fettabbau, Leistungssteigerung oder Longevity – kaum ein Bereich wird so intensiv beworben wie Supplements. Gleichzeitig wächst der Markt rasant: Zwischen wissenschaftlich belegten Produkten und geschicktem Marketing liegen jedoch oft Welten. Influencer, Hersteller und MLM-Systeme versprechen häufig mehr, als die aktuelle Evidenz tatsächlich hergibt. Wer den Überblick behalten möchte, sollte zwischen nachgewiesener Wirkung und teuren Versprechen unterscheiden.

 

Die Top 5: Welche Supplements überzeugen wirklich?

Nicht jedes Supplement ist Geldverschwendung. Einige Wirkstoffe zeigen in der Forschung wiederholt positive Effekte, wenn sie gezielt eingesetzt werden.

Kreatin zählt zu den am besten untersuchten Nahrungsergänzungsmitteln überhaupt. Es kann Kraft, Muskelmasse, Regeneration und Leistungsfähigkeit bei intensiven Belastungen verbessern. Gleichzeitig widerlegt die aktuelle Evidenz zahlreiche Mythen – etwa die Behauptung, Kreatin verursache Haarausfall oder schädliche Wassereinlagerungen.

Beta-Alanin entfaltet seine größten Vorteile bei hochintensiven Belastungen, indem es die Ermüdung hinauszögert. Besonders Sportarten mit Belastungen zwischen 30 Sekunden und zehn Minuten profitieren von einer gezielten Supplementierung.

Koffein verbessert Wachheit, Konzentration und kann die subjektive Anstrengung senken. Richtig dosiert zählt es zu den wirksamsten legalen Leistungsboostern, ersetzt jedoch weder Training noch Regeneration.

Nitrate, beispielsweise aus Rote-Bete-Saft, verbessern die Sauerstoffversorgung der Muskulatur und können sowohl Ausdauer- als auch Kraftleistungen unterstützen. Die Effekte hängen jedoch stark von Dosierung und individuellem Ansprechen ab.

Anstelle von Proteinpulvern gehört für den Autor Citrullin in die persönliche Top-5-Liste. Als Vorstufe von Arginin unterstützt es die Stickstoffmonoxid-Bildung, wodurch Durchblutung, Regeneration und möglicherweise auch Herz-Kreislauf-Funktionen profitieren können. Gleichzeitig zeigt die Studienlage, dass nicht alle beworbenen Effekte gleichermaßen gesichert sind.

 

Die Flop 5: Viel Marketing, wenig Nutzen

Auf der anderen Seite stehen Produkte, deren Nutzen häufig überschätzt wird.

Multivitaminpräparate vermitteln Sicherheit, bieten gesunden Menschen jedoch meist keinen nachgewiesenen Vorteil. Im Gegenteil: Überdosierungen einzelner Vitamine oder Mineralstoffe können gesundheitliche Risiken bergen und Wechselwirkungen verursachen.

Fatburner leben vor allem von Werbeversprechen. Zwar können einzelne Inhaltsstoffe wie Koffein oder Grüntee den Energieverbrauch geringfügig beeinflussen, für eine nachhaltige Gewichtsreduktion bleiben Ernährung, Bewegung und ein Kaloriendefizit entscheidend.

Auch BCAA-Präparate schneiden schlechter ab als ihr Ruf vermuten lässt. Wer ausreichend hochwertiges Protein aufnimmt, profitiert in der Regel nicht von einer zusätzlichen BCAA-Supplementierung.

Ähnlich kritisch bewertet der Beitrag Kollagenpräparate. Obwohl sie intensiv für Haut, Gelenke und Anti-Aging beworben werden, liefern hochwertige Studien bislang keine überzeugenden Belege für die meisten versprochenen Wirkungen.

Auch Glucosamin, Chondroitin und MSM werden häufig bei Gelenkbeschwerden empfohlen. Die bisherige Evidenz zeigt jedoch allenfalls geringe oder widersprüchliche Effekte, während Bewegung und Krafttraining weiterhin die wirksamsten Maßnahmen bleiben.

 

Das Fazit

Der Supplement-Markt folgt häufig dem Prinzip: Je größer das Versprechen, desto größer das Marketingbudget. Gleichzeitig zeigt die wissenschaftliche Evidenz, dass nur wenige Nahrungsergänzungsmittel tatsächlich einen relevanten Zusatznutzen bieten – und selbst diese ersetzen niemals Schlaf, Training, ausgewogene Ernährung oder Regeneration.

 

Doch welche Dosierungen sind wirklich sinnvoll?

Welche Mythen rund um Kreatin wurden wissenschaftlich widerlegt?

Warum gehören Proteinpulver nicht in die persönliche Top-5-Liste und welche Supplements können im schlimmsten Fall sogar schaden?
