REAL REVIEWS FROM REAL PEOPLE
CONFESSIONS FROM THE BRIGHTSIDE
What will it feel like?
Calm, clear, and a little lighter. One of our customers put it best:
"Like putting on your most comfortable clothing."
-Mike B. | verified buyer
What makes this work?
One ingredient: Zembrin® is a standardized extract from a South African succulent (also known as kanna), a botanical with a long history of traditional use.
Why only one functional ingredient?
Because one great thing done right beats ten mediocre things done vaguely.
Most brands stack ashwagandha, magnesium, and whatever else made the trend report, hoping something works. We use just one functional ingredient, so you always know what you're getting.
When should I drink it?
Anytime. Morning meeting, afternoon slump, first date jitters, a night out where you want to be present, or whenever someone's testing your patience, and you'd rather stay chill and unbothered.
On the Brightside is caffeine-free, so there's no wrong time to crack one open.
What are the ingredients?
Strawberry Sunshine is made with carbonated water, crystallized lemon, organic natural flavors, citric acid, malic acid, fermented Reb M, vegetable juice (for color), and Sceletium Tortuosum extract (aerial parts).
Guava Glow is made with carbonated water, organic natural flavors, citric acid, malic acid, fermented Reb M (Onosweet®), vegetable juice (for color), and Sceletium Tortuosum extract (aerial parts).
