Can You Take Caffeine and CarnoSyn (Beta-Alanine SR) Together?

May affect absorption

The short answer

Caffeine is acidic and may alter gastric pH, potentially affecting the sustained-release mechanism of CarnoSyn (sustained-release beta-alanine). This could lead to faster release and increased paresthesia.

How to arrange timing

Take CarnoSyn with food and separate from caffeine by 30–60 minutes to preserve the sustained-release profile.

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.
