EngagementModerate engagement

ImpactModerate impact

The overall tone suggests that users see the publication as moderately impactful, with some statements implying a skeptical but open attitude toward the supplement's potential, such as noting that larger doses are needed for significant fat loss.

Abstract in brief

  • The systematic review and meta-analysis of 37 RCTs found that l-carnitine supplementation significantly reduces body weight, BMI, and fat mass, with the maximum effect at a dose of around 2000mg per day.
  • No significant effects were observed for waist circumference or body fat percentage, and high-quality RCTs only confirmed the benefits on body weight.
  • A nonlinear dose-response relationship suggests that taking approximately 2000mg of l-carnitine daily offers the greatest weight reduction benefits in adults, especially those who are overweight or obese.

La L-carnitina no genera un efecto significativo sobre la pérdida de peso. Podría ayudar algo en sujetos obesos, pero no impacta de forma determinante. https://t.co/GB85PK9aPl

Glutaminden ziyade L-Carnitine daha umut verici gözüküyor kilo verme noktasında. L-Carnitine takviyesi alan obez ya da kilolu kişilerde normal BMI aralığındaki L-Carnitine takviyesi alan kişilere kıyasla daha fazla kilo kaybı görülmüş. https://t.co/zSrBMcZJSS

Дальше по списку Л-карнитин. Это соединение, которое транспортирует жирные кислоты в митохондрии (а.к.а сжигает жир). За счет этого его подносят как добавку для похудения. Четкого консенсуса тут нет. Вроде помогает, а вроде и нет https://t.co/FvZvSxx9Ig
