Overview

Source Naturals Theanine Serene is a dietary supplement formulated to support relaxation and focused attention. Its blend centers on L-theanine, the calming neurotransmitter GABA, taurine, magnesium, and holy basil leaf extract, bringing together several ingredients commonly used to encourage a more relaxed state while also supporting mental clarity.

The formula is designed to provide broader calming support than a simple single-ingredient product. L-theanine is included for relaxation and concentration support, while GABA contributes additional calming activity. Taurine is described as helping support potassium movement out of neurons, which may help limit neuronal overexcitation. Magnesium is added for muscle and nerve relaxation, and holy basil leaf extract rounds out the formula with a soothing botanical component.

This supplement is suitable for vegetarians and is presented in tablet form. It is intended as a daily calming formula rather than a short-term, single-purpose product, making it a multi-ingredient option for people looking for support with both mind and body relaxation.
