Can You Take Glycine Propionyl-L-Carnitine and Propionyl-L-Carnitine Together?

Use extra care with this pair

The short answer

GPLC contains propionyl-L-carnitine as its carnitine component. Combining with standalone Propionyl-L-Carnitine provides a redundant and potentially excessive dose of the same active compound.

How to arrange timing

Do not stack GPLC with Propionyl-L-Carnitine as this amounts to double-dosing the same compound.

Reference

Reference noted for this combination: Bloomer RJ, et al. Glycine propionyl-L-carnitine modulates lipid peroxidation and nitric oxide in human subjects. Int J Vitam Nutr Res. 2009;79(3):131-141.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
