“I've used 5-HTP for years in clinical practice as a research-based way to help people manage cravings, balance mood, and feel more in control of their choices. Slacka takes that powerful science and delivers it in a refreshing, real-world form. It's not just a feel-good drink—it's a tool for taking control of your mind, your habits, and your day.

Got Questions?

Coach (That's Us) Has Answers:

Can it really help curb cravings?

Yes. Users report reduced snacking and more mindful food decisions within the first week.

Will it make me jittery?

Nope. Slacka uses paraxanthine, which provides alertness without the anxiety of traditional caffeine.

What does it taste like?

Bright, refreshing, and nostalgic. Think: berry punch with a grown-up twist.

Is it zero sugar?

Yes—zero sugar, low calories, nothing artificial.

When should I drink it?

Before meals for portion control, in the afternoon for snack control, or pre-meeting for focus.

Can I take this with medications?

If you're on medications (e.g., SSRIs), check with your healthcare provider first.
