About FitBoost

Most energy drinks are just sugar, caffeine, and hype. FitBoost is none of those.

This ultra-premium, sugar-free mix is built for people who care about how their body actually performs—not how loud the label is. It combines caffeine pterostilbene co-crystal (for smoother, longer-lasting energy), Albion® chelated minerals and B vitamins (for hydration and metabolism), and powerhouse antioxidants like S-Acetyl-L-Glutathione and 500 mg of Vitamin C (for cellular defense and recovery).

The result? Clean energy that sustains you—without the crash, the sugar, or the side-eye from your coach.

FitBoost is what you grab when you want to stay sharp, stay moving, and stay ahead.

Never thought an energy drink mix could be this refreshing and efficient. FitBoost (berry) has not only made hydration more enjoyable but also significantly upped my energy levels without any subsequent crashes. It’s refreshment and vitality in a stick.
