The fiber gap

There’s a gap in your diet.

If your bathroom schedule is all over the place. If you feel backed up more often than not. If you’re hungry again an hour after you just ate. Your fiber intake may be part of the problem.

Most adults need 25 to 35 grams of fiber a day. But the average American only gets about 14 grams. That gap is the most overlooked piece of feeling good day to do. Easy Mix Fiber helps you close that gap.

90 %

of Americans aren't getting enough daily fiber. 6g per serving covers 21% of your daily value — in an easy-to-enjoy daily ritual.

Easy Mix Fiber is different

Why most fiber powders fall flat

🤢

They clump and turn to sludge.

You stir, and stir, and it still leaves a gritty layer at the bottom of the glass. By day three, the tub is in the back of a cabinet.

🚫

Artificial junk you don't want daily.

The leading fiber brand uses artificial sweeteners (aspartame), artificial flavors, and Yellow 6. Not the thing you want to drink every morning.

😤

They leave you bloated and gassy.

Some fibers ferment too fast and trade one kind of discomfort for another. The whole point was to feel better, not worse.

The benefits

Easy Mix Fiber does more


How it works

Soluble fiber absorbs water in your digestive tract and forms a gentle gel that helps food move through more comfortably.


What it means

Meals sit easier. Your stomach doesn’t feel like a knot after big lunches or late dinners.


How it works

Soluble fiber absorbs water and helps form stools that pass comfortably. Easy Mix Fiber’s two natural fibers do this gently, without the sudden urgency or cramping. And when you’re less backed up, that heavy, sluggish feeling most people don’t realize is coming from their gut starts to ease up.‡


What it means

You go on a schedule you can count on. And when you’re less backed up, the day starts lighter, without the heaviness you’d been carrying. You feel like yourself again.


How it works

Soluble guar fiber forms a gentle gel in your stomach that slows digestion. Slower digestion means you feel full longer and have more stable energy between meals.‡


What it means

Less reaching for a snack at 3pm even though you ate well. More in control of your appetite, instead of chased by it.


How it works

On a GLP-1, you’re eating less, which makes hitting your daily fiber target harder. Easy Mix Fiber adds 6g of clean prebiotic fiber to whatever you’re already drinking. No extra calories. No artificial sweeteners. No grit.‡


What it means

You hit your fiber goal even on smaller portions. You stay regular and comfortable. The daily habit built for the routine you’re already on.


How it works

Prebiotic fiber is food for the beneficial bacteria in your gut microbiome. Easy Mix Fiber’s two fibers ferment slowly in your colon, fueling those bacteria without the gas and bloating that fast-fermenting fibers cause.‡


What it means

A more balanced gut microbiome that supports digestion, immune function, and overall wellbeing. The foundation under everything else.

How it works

Two natural sources of science-backed fiber.

The two fiber sources in Easy Mix Fiber ferment slowly in your gut over time instead of all at once. That is why most people don't get the cramping, gas, or bloating they've had with other fiber supplements.

Both are soluble fibers, clinically studied to support healthy digestion, regularity, and feelings of fullness. They work in your gut, not just through it.

1

Soluble Corn Fiber

A plant-based prebiotic fiber your body can't digest, but your gut bacteria love. Ferments slowly, which means it fuels your microbiome without the gas and bloating most fibers cause.

2

Soluble Guar Fiber

A natural fiber from the guar bean. Gently broken down so it dissolves completely. Forms a gentle gel that helps you feel full between meals and keeps digestion comfortable.

GLP-1 Friendly

Your GLP-1 journey needs fiber.

Smaller meals make hitting your daily fiber target harder. Easy Mix Fiber™ is clean, grain-free, gentle — and one stick pack adds 6g of clean prebiotic fiber to whatever you're already drinking.

Supports satiety — soluble fiber forms a gentle gel that helps you feel full longer.
Supports regularity — gentle two-fiber blend keeps things moving on a smaller appetite..
Clean & simple — No artificial ingredients, or unnecessary filler.

Honest answers

Questions? We've got answers

Three things. First, ingredients: no artificial sweeteners (no aspartame), no artificial flavors, no artificial dyes (no Yellow 6). The flavored options use just 2g of natural cane sugar plus stevia. Second, texture: Easy Mix Fiber uses two natural soluble fibers that dissolve completely, so you don't get the clumpy, gritty layer at the bottom of your glass. Third, the gut response: the two fibers ferment slowly, so most people don't get the gas and bloating they've had with other powders.
The Unflavored version is exactly two ingredients: Soluble Corn Fiber and Soluble Guar Fiber. Nothing else. Sugar-free, no flavors, no dyes, no artificial sweeteners. The Peach Mango and Cucumber Lime versions add natural flavors, 2g of natural cane sugar, and stevia for sweetness. No artificial anything.
Unflavored: Mix 1 heaping spoonful into your favorite hot or cold drink or food. Stir, shake, or blend for 60 seconds. Yes, it works in coffee. Yes, it works in smoothies, tea, juice, water, oatmeal, and yogurt. It dissolves clear and tasteless. Peach Mango and Cucumber Lime: Add 1 heaping scoop to 8 to 10 oz of water.
Most people start to feel the benefits after about two weeks of daily use. If your body isn't used to higher fiber, you may notice some gas or bloating during the first week as your gut microbiome adjusts. That's normal. Start with one scoop, drink plenty of water, and work up gradually.
No, they complement each other. Probiotics are the beneficial bacteria. Prebiotic fiber is what those bacteria eat. Easy Mix Fiber pairs well with every Physician's Choice probiotic, including the 60 Billion Probiotic, Women's Probiotic, and Digestive Enzymes.
