Overview

Sereniten Plus combines well-researched ingredients for stress, mood, and sleep support. While Lactium is included at an effective dose, the L-Theanine dose is at the lower end of the effective range for some benefits, and Vitamin D3 is included at a low dosage. The overall formula appears geared towards mild to moderate stress and mood support.

The Good

Lactium is included at a clinically effective dose for stress and sleep benefits.

L-Theanine can promote relaxation without sedation.

Vitamin D3 at a relatively low dose

Contains milk, unsuitable for those with dairy allergies/intolerance

Is it for you?
