About FitProbio+

Most probiotics talk a big game about “gut health” and then ghost you when it counts. FitProbio+ actually delivers—with clinically studied HOWARU® B420, shown in human trials to support reduction in body fat mass, lower calorie intake, and stronger gut barrier integrity without requiring lifestyle changes.

Each capsule is packed in nitrogen-sealed blister packaging to protect potency from heat, moisture, and oxygen. And to make sure it gets where it matters, we use DRcaps™ delayed-release capsules that bypass stomach acid and head straight to the intestines—no fancy yogurt, no filler strains.

There’s no dairy. No gluten. And no “just trust us” fluff. Just targeted gut support that helps you feel better, look better, and stay in control of what your body holds onto.

How to Use

Take one (1) capsule with water daily, or as directed by your healthcare professional.

The Typical User Journey

A simple timeline of how FitProbio+ commonly becomes part of a routine.

Day 1
You may notice digestion feels a bit smoother and less unpredictable. Nothing dramatic — just a cleaner start to the day as your gut gets acquainted with a strain built for more than “general wellness.”
Week 1
Your routine begins to feel more balanced. Appetite patterns may feel steadier, bloating may ease, and daily intake becomes easier to manage without as many swings or derailments.
Week 4+
Consistency pays off. Your gut feels more supported, appetite control becomes more natural, and you may feel more aligned with your nutrition and body-composition goals across the week.

Frequently Asked Questions

What makes FitProbio+ different from other probiotics?

FitProbio+ uses the clinically studied HOWARU® Shape B420 strain, delivered in DRcaps™ gastro-resistant capsules and nitrogen-purged blister packs for added stability. Most probiotics rely on generic blends with no research behind them.

Do I need to refrigerate FitProbio+?

No. FitProbio+ is formulated and packaged to maintain stability at room temperature, thanks to its sealed, nitrogen-purged blister packs.

When should I take FitProbio+?

You can take it any time of day. Morning tends to work best for building a consistent routine. FitProbio+ does not contain stimulants.

Can I take FitProbio+ on an empty stomach?

Yes. DRcaps™ capsules are designed to help protect the strain as it passes through the stomach, whether you’ve eaten or not.

How long does it take to notice a difference?

Every microbiome is different. Some users notice changes in digestion and appetite patterns sooner; for others, it may take several weeks of consistent daily use.

Is FitProbio+ safe for daily use?

Yes. FitProbio+ is designed for long-term, daily use and includes a probiotic strain shown to be safe and well-tolerated in clinical research.

Does FitProbio+ help with body composition?

FitProbio+ features a probiotic strain that has been studied for its role in supporting gut barrier integrity, appetite patterns, and body fat mass. Individual responses vary.

What does the B420 strain actually do?

B420 has been researched for its ability to support gut barrier function, modulate gut microbiota, and influence appetite and caloric intake, all of which contribute to a healthier body composition environment.

Why are the capsules individually sealed?

Exposure to heat, moisture, air, and light can reduce probiotic viability. Our nitrogen-purged blister packs help protect potency until the moment you take it.

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.
