PreBio Fiber is a botanically-derived fiber supplement designed to promote optimal intestinal function, support healthy GI motility, and enhance bowel regularity. It helps to maintain a healthy microbial balance in the digestive tract and may benefit those following a Paleo-style diet.* PreBio Fiber includes 12 different types of fiber, without the harsh proteins or irritating components commonly found in other fiber products, making it an ideal choice for digestive health. This product supports weight management, glucose metabolism, and lipid metabolism.*
Recommended Use
Take 5 grams (approximately one scoop) per day or as directed by your healthcare practitioner. Be sure to consume extra water when taking PreBio Fiber.
*None of these statements have been evaluated by the Food and Drug Administration. These products are not intended to diagnose, cure, or prevent any disease.
Prebiotic fibers resist digestion in the small intestine and reach the colon intact, where they selectively ferment beneficial bacteria like Bifidobacteria and Faecalibacterium, producing short-chain fatty acids that nourish colonocytes.
Dose: 1 teaspoon daily
Those with FODMAP sensitivities may experience bloating initially. Introduce slowly to avoid digestive upset. Not recommended for those with active Small Intestinal Bacterial Overgrowth.
Why is my gut inflamed in the first place? Chronic stress, processed food, antibiotics, alcohol, and environmental toxins all damage the gut lining over time. Most people don't realize how compromised their gut is until they start fixing it and feel the difference. It's one of the most overlooked root causes of fatigue, brain fog, and immune problems.
How long until I notice a difference? Bloating and digestive discomfort usually improve within 1–2 weeks. Deeper gut lining repair, better nutrient absorption, and the downstream effects on energy and clarity build over 4–8 weeks of consistent use.
I've tried probiotics before and didn't notice much. Why would this be different? A single-strain probiotic dropped into a damaged, inflamed gut doesn't do much — it's like repainting a wall with a crack in it. These formulas address the lining itself first, then restore the bacterial environment. That's why people who got nothing from probiotics actually feel this one.
Will this help with bloating specifically? Yes. Bloating is almost always a sign of gut inflammation and poor digestion. As the lining heals and absorption improves, most people see significant reduction in bloating within the first two weeks.
Can I take this alongside my other supplements? Yes, and you should. A healthier gut means you actually absorb everything else you're taking. Think of gut repair as the foundation that makes the rest of your supplement protocol work properly.
Do I need to change my diet for this to work? You don't have to overhaul everything. Reducing processed food and alcohol helps, but these formulas are designed to work as part of your daily routine without requiring a complete lifestyle change.

PreBio Fiber 10oz
Your Stomach Is Always Bloated. You're Uncomfortable After Every Meal.
You used to enjoy eating. Now every meal is followed by bloating, gas, or discomfort. You've tried cutting out foods, taking digestive enzymes, probiotics, but nothing really works. Your energy is low. You're not absorbing nutrients properly. You're tired of feeling uncomfortable in your own body. Nobody ever told you it might be your gut lining that's damaged.
- You feel bloated and uncomfortable after most meals.
- Your digestion is slow and inconsistent.
- You're tired all the time because you're not absorbing nutrients properly.


Your Gut Lining Is Damaged. Your Digestion Can't Keep Up.
It's not something that hurts all the time. But it quietly stops you from absorbing nutrition and feeling good.
Every processed meal. Every year of stress. Every inflammatory food. Your gut lining breaks down. Your digestive system can't function properly. Your body can't absorb nutrients. That's why you're bloated, tired, and uncomfortable.
Most digestive products just reduce symptoms. They don't actually heal your gut lining. That's why the bloating comes back when you stop taking them. You're treating the symptom, not the source.
Not a digestive enzyme. Not a probiotic. A compound that actually heals your gut lining and restores your digestive function so you can absorb nutrients and feel good again. When it does, everything changes.
What Most People Notice And When

Built by a board-certified cardiologist with 30+ years of clinical experience, not a marketing team.
Dr. Gladden walked away from medicine to prove biology could be optimized, not just managed. At 72, his biological age tests at that of a man in his early 27. He doesn't recommend these products. He uses them himself every single day.
He snowboards extreme terrain. Mountain bikes. Jumps out of helicopters to go backcountry skiing. Things most people in their 40s have already stopped doing.
Every product in this store is what he takes to keep doing it.

Real Results From Real People
These are actual Gladden Longevity verified customers that have seen successful outcomes by consistently being on the Gladden protocol
My doctor actually mentioned nitric oxide support to me during a routine appointment and i found this through Dr Gladden's podcast. Three months in. Blood pressure is down slightly and i feel way better on the bike. My wife keeps asking why i seem younger lol
Ok so i was fully prepared to return these. took them for about 10 days and thought nothing was happening. then i had a week where i ran out and forgot to reorder and that's when i realized something had actually been working. hard to explain but the best way i can describe it is that my brain just felt... quieter and faster at the same time. been on them 3 months now
Bought these because my buddy who's a doctor wouldn't stop talking about molecular hydrogen. Figured i'd try it. I'm not someone who writes reviews but i'm 58 and i haven't felt this good after a workout since my 40s. Recovery is just faster.
I'll be honest the price made me hesitate for like two weeks. Finally bought them. Wish I hadn't waited. I take one in the morning with water before coffee and I just feel... on. Not wired. Just on. My wife asked what I was taking and she's now on them too lol
I have a really hard time shutting my brain off at night. Like genuinely hard. I've tried magnesium, ashwagandha, melatonin, all of it. The melatonin stopped working years ago and made me groggy anyway. This is completely different. I don't feel like I took something. I just... fall asleep. Like a normal person. I don't know how.
Took this for the first time on a Sunday night after a stressful week and slept 7.5 hours straight. Woke up and actually felt rested which hasn't happened in maybe two years. Ordered a second bottle before the first one was done
I've tried turmeric capsules before and they did absolutely nothing. My trainer told me the bioavailability on regular curcumin is terrible and that's why. Picked up UltraCur Pro kind of reluctantly. About 5 weeks in the knee pain I've had after runs for like two years is noticeably better. Not gone but like... 60% better. I'll take it
Genuinely did not think this would be different from every other curcumin thing I'd tried. I was wrong. I do manual work and I'm 54 and the inflammation in my hands and lower back has been something I just accepted. A month on this and I've had to reconsider that. Still can't fully explain it but something is working
Started taking this about 6 weeks ago. I run 4x a week and the difference in how i feel on mile 4 and 5 vs before is real. Less effort, better breathing. I don't know how else to say it. just easier.
