The Active Ingredient Is: Carnitine (Multi-Form Blend)

Carnitine is a naturally occurring compound involved in cellular energy production and is supplied here as a multi-form blend to support energy and vitality. This blend includes Acetyl L-Carnitine HCl, Acetyl L-Carnitine Arginate Di-HCl, and Glycine Propionyl L-Carnitine HCl to provide diverse functional forms.

These forms are sourced as dietary supplements to support healthy energy metabolism and vascular function in adults, with the combination aimed at broad energy and cognitive support alongside physical performance needs.

What Does Carnitine Do?

Carnitine acts as a cellular energy shuttle by aiding the transport of fatty acids into mitochondria for energy production. Acetyl L-Carnitine can cross the blood-brain barrier and may support cognitive function, while GlycoCarn can promote nitric oxide production and vascular function, aligning with EFSA-informed mechanisms.

This section summarises how multiple carnitine forms can contribute to energy generation, brain function, and circulation, with research indicating these mechanisms underpin daily vitality and resilience.
