Quick answer

Take Glutathione-SR 30–60 minutes before your pre-workout to allow absorption, then consume your pre-workout 15–30 minutes before training.

Why timing matters between an antioxidant and a stimulant

Glutathione-SR is a sustained-release antioxidant that supports cellular detoxification and immune function. Pre-workout formulas usually contain stimulants, creatine, and nitric oxide boosters that work best on an empty stomach or with a short absorption window. Taking both at the exact same time can blunt the acute effects of the pre-workout because glutathione may slow gastric emptying slightly. Spacing them by at least 30 minutes solves this.

What to expect from this stack

You get the long-term antioxidant and liver-support benefits of glutathione without interfering with the energy, focus, and pump you expect from a pre-workout. Over time, this combination may help reduce exercise-induced oxidative stress, but the immediate effect is simply a cleaner energy experience.

Step-by-step layering guide

  1. Step 1: Take Glutathione-SR 30–60 minutes before your workout: Swallow one capsule of Glutathione-SR with 4–6 oz of water. The sustained-release coating needs about half an hour to begin breaking down, so this timing ensures the antioxidant is active during your training session. Do not take it with food or other supplements that contain calcium or iron, as those can interfere with absorption.
  2. Step 2: Wait 15–30 minutes, then take your pre-workout: Mix one scoop of Pre-Workout Elite with 8–12 oz of cold water and drink it 15–30 minutes before you start exercising. This gives the stimulants and performance ingredients time to enter your bloodstream. If you feel jittery, you may be sensitive to caffeine; try half a scoop first and adjust up.
  3. Step 3: Hydrate during your workout: Sip water throughout your session. Both supplements are concentrated and can cause mild dehydration if you skip water. Aim for 6–8 oz every 15 minutes. Check your urine color; pale yellow means you are well hydrated.
