When to drink it:
Use when you need to chill out or anytime before bed—especially on stressful days or if you’ve had caffeine.

How to drink it: Mix one SuperCalm packet with 8 oz of cold water, stir or shake well, and enjoy.

Most people begin to feel the calming effects within 15–30 minutes after drinking Rehydra SuperCalm, though timing can vary depending on your body, stress levels, and caffeine intake. For best results, use consistently and allow your body time to respond.

Some ingredients, like L-theanine, may begin to take effect in as little as 30 minutes after consumption. Other ingredients, such as KSM-66® Ashwagandha, work more gradually, with benefits that build over time—most clinical studies have evaluated results over a 90-day period with consistent use.

Even Though SuperCalm promotes deeper, more restorative sleep and improve overall sleep quality, it does not directly cause drowsiness. You can take it to support relaxation without feeling tired. 

SuperCalm is generally well tolerated. Most people report feeling calm with a sense of light focus. When used as directed, it’s not associated with jitteriness or heavy sedation.
