Energy for People Who Read Labels

Most energy drinks are sugar water with a marketing budget. FitBoost isn’t playing that game.

This ultra-premium, sugar-free mix delivers smooth, sustained energy using caffeine pterostilbene co-crystal, Albion® chelated minerals, B vitamins, and serious antioxidant support. No spikes. No crash. No candy-sweet shortcuts.

The result is clean energy that keeps you sharp, hydrated, and moving—without jitters, sugar, or excuses.

If you rely on energy to perform, not just feel awake, this is your move.

Made for People Who Don’t Run on Luck

If you want reliable, steady energy without the nonsense, you’re in the right place.

  • Who It’s For:

    • Anyone who wants clean, consistent energy without the mid-day crash
    • People who prefer transparency and high-quality ingredients over hype
    • Lifters, runners, and desk warriors who need fuel that lasts
    • Those who want an energy boost without the sugar rush
    • High-performers who’d rather invest in something that actually works

  • Who It’s Not For:

    • Bargain hunters looking for the cheapest caffeine on the shelf
    • Fans of jittery, hard-crash energy drinks that glow like a nightclub
    • People who want a sugar bomb disguised as “energy”

What’s Inside (And Why You’ll Never Look Back)

Ultra-premium ingredients selected to support smooth energy, antioxidant activity, and everyday performance without the sugar crash.

Caffeine Pterostilbene Co-Crystal

Provides smoother, longer-lasting energy compared to standard caffeine sources.

Electrolytes

Replenish key minerals that support hydration, performance, and muscle function.

S-Acetyl-L-Glutathione

A stable, highly absorbable form of glutathione that helps defend against everyday oxidative stressors.

Vitamin C

Supports antioxidant activity and helps combat free radicals created during training and daily stress.

Formulated to exclude: wheat, gluten, yeast, soy protein, animal and dairy products, fish, shellfish, peanuts, tree nuts, egg, ingredients derived from genetically modified organisms (GMOs), artificial colors, artificial sweeteners, and artificial preservatives.

Other ingredients include: maltodextrin, citric acid, malic acid, natural grape powder, natural flavors (no MSG), stevia leaf extract, and silica.

The FitBoost Difference Over Time

A clean energy experience that many notice early, with benefits that build as you stay consistent.

  • Day 1

    A cleaner lift in energy without the spikes. You may feel more alert, more focused, and less weighed down by mid-day drag. No hard crash waiting on the other side.

  • Week 1

    Energy starts to feel more stable throughout the day. Work, training, and everyday tasks become easier to move through without relying on constant caffeine top-ups.

  • Week 4+

    Your daily rhythm begins to feel smoother and more consistent. That reliable, steady momentum becomes something you can build on instead of something you chase.

How to Use FitBoost

  • Mix 1 stick pack with 10–12 oz of cold water
  • Sip 15–30 minutes before training or when you need a clean boost
  • On lighter days, use in the morning to set your energy baseline

Use daily for consistent results and smoother energy throughout your routine. For afternoon or evening use, avoid drinking within 4–6 hours of bedtime if you’re sensitive to caffeine.

Pro Tip: If you’re new to caffeine or prefer a milder lift, start with half a stick pack and adjust to your ideal level.

Frequently Asked Questions

How much caffeine is in FitBoost?

Each serving contains 95mg of caffeine sourced from caffeine pterostilbene co-crystal. This form is designed to be released more gradually than standard caffeine, which many people find gives a smoother, more controlled lift.

Will FitBoost make me feel jittery?

Most people find that FitBoost delivers a steadier energy experience thanks to the gradual-release nature of the caffeine pterostilbene co-crystal. Everyone responds differently to caffeine, so start with a smaller amount if you’re sensitive.

What if I’m new to caffeine or low-stimulant products?

Begin with half a stick pack to assess your ideal level. Many people adjust serving size based on their personal tolerance and how much caffeine they consume from other sources.

Will FitBoost keep me up at night?

If you’re sensitive to caffeine, avoid taking FitBoost within 4–6 hours of bedtime. For morning or early-afternoon use, most people find it fits easily into their routine.

When should I take FitBoost?

Use FitBoost 15–30 minutes before training or whenever you need a clean boost in energy and focus. On non-training days, morning use is a popular choice.

Can I take FitBoost on an empty stomach?

Yes, FitBoost can be taken with or without food. If you’re sensitive to caffeine, you may prefer pairing it with a light meal or snack.

Can I use FitBoost on non-training days?

Absolutely. Many people rely on FitBoost for workdays, long mornings, travel, or any time they want steady, crash-free energy without sugar.

What’s the difference between FitBoost and FitBoost+?

FitBoost is a clean, steady-energy drink mix with electrolytes, antioxidants, and gradual-release caffeine technology. FitBoost+ is a pre-workout designed for more intense training sessions and includes additional performance-focused ingredients.

Can FitBoost replace my usual energy drink or coffee?

Many people use FitBoost in place of sugary energy drinks or high-caffeine beverages. It offers a cleaner, lower-carb option with a smoother energy curve.

Can I stack Fitties products together?

Yes. All Fitties supplements are designed to work safely and effectively together. If you want a ready-made stack, our curated bundles pair the right products for strength, performance, recovery, and overall health so you don’t have to guess.

Are Fitties products third-party tested?

Yes. Every Fitties formula goes through independent third-party testing to verify purity, potency, and identity before it ever reaches your hands. No hidden extras. No low-grade shortcuts. Just ultra-premium, research-backed ingredients that deliver exactly what the label says.

Where are Fitties products made?

All Fitties supplements are manufactured in the USA in cGMP-certified, FDA-registered facilities. We don’t outsource quality. We build everything to the highest standard because your health and performance deserve nothing less.

Are Fitties supplements vegan, gluten-free, or allergen-friendly?

Each product is different, and we call out all dietary details clearly on every product page. Many formulas are vegan, gluten-free, dairy-free, or soy-free — and we never use artificial dyes or cheap fillers. If something doesn’t fit your dietary needs, you’ll know upfront.
