Protein • Fiber • GLP-1 Support
8 Reasons Pure Genius Protein + Fiber Is Your GLP-1's Best Friend
On a GLP-1, your appetite dropped, and so did everything you used to get without thinking about it. Protein, fiber, all of it. Pure Genius Protein + Fiber puts 20g of protein and 5g of fiber in one 3.38 oz shot, small enough to finish on the days you can barely eat.

On a GLP-1 protein and fiber are the first to go.
GLP-1s kill your appetite, so you eat less. The problem is, protein and fiber are more filling than other nutrients. So they're the hardest to get enough of. The usual fixes don't work when you're barely hungry. A full plate of vegetables or fruit is more than you can finish. A chicken breast and a couple of eggs is more than you can get down. Pure Genius Protein + Fiber covers both in one small drink, even on the days you can barely eat.
01
Less food means less fiber too
Everyone talks about the protein. Almost no one warns you about the fiber.
When your appetite drops, the high-fiber foods go first: fruit, vegetables, whole grains, the ones that take the most effort to eat. So you end up short on fiber and short on protein at the same time. Pure Genius closes both gaps in one shot, instead of asking you to solve two separate problems on a day you would rather not think about food at all.
02
Constipation is one of the most reported GLP-1 side effects
If your gut feels stuck, it's not just you.
Constipation is one of the most common complaints people report on GLP-1 medications. Slowed digestion is part of how these drugs work, and fiber is usually the first thing to fall short when your appetite drops. Pure Genius delivers 5g of fiber to help get things moving again. No laxatives, no guesswork, just easier, more regular digestion built into the same shot as your protein.
03
PROTECT YOUR MUSCLE
Prevent lean mass loss from GLP-1s.
As much as 40% of the weight you lose on a GLP-1 can be lean mass, not fat. Protein helps protect it. Each shot contains 20 grams of a high-quality protein blend packed with leucine and all 9 essential amino acids your body can't make on its own. That's what makes it so valuable for muscle.
Why leucine: Leucine is the amino acid that signals your body to build and repair muscle. Pure Genius uses beta-lactoglobulin, the most leucine-rich part of whey, so each shot carries 2.4g. That's more per gram of protein than chicken breast, beef, or salmon.

04
Three sips, not another shake
On a GLP-1, you can't even think about a 16 oz shake. This is 3.38 ounces.
A big shake, a bowl of oatmeal, a plate of vegetables. On a GLP-1, that much volume is not something you skip, it's something you physically can't get down. This is one small shot, finished in three sips, that goes down even when your appetite is gone. Nothing to force, nothing sitting heavy after.
05
Zero sugar. No grit.
The other "easy" fiber is working against you.
Fiber gummies are packed with sugar or sugar alcohols. Fiber powders are gritty and need mixing. On a GLP-1, added sugar and a chalky drink are the last things you want near your stomach. This is 5g of soluble tapioca fiber and 20g of protein, zero sugar and zero fat, in a shot that tastes like juice, not a supplement.

20g protein

06
Feed the bacteria your gut still needs
The trillions of bacteria in your gut control more than digestion.
A GLP-1 changes how much you eat, but your gut bacteria still need feeding to stay balanced. The 5g of fiber in Pure Genius feeds the good bacteria in your microbiome, and a happier gut could mean less bloating, better nutrient absorption from what you do eat, steadier blood sugar, better appetite management, and real support for keeping the weight off long term, not just losing it.
07
Gentle on your stomach
It goes down easy, even on the hard days.
GLP-1 medications can leave your stomach sensitive, especially in the first weeks or after a dose increase. Most protein sources make it worse. Shakes sit heavy. Bars are too dense to finish. Pure Genius drinks like juice: no thickness, no bloat, nothing sitting there afterward. Three sips. Done.

"I spend so much time educating people about protein's critical role in their health — energy, muscle, longevity. But once they understand the need, finding convenient, quality sources becomes the real obstacle. Knowledge without accessible solutions doesn't help. That's what we're changing."

"My mother is 85 and still fully herself - sharp, joyful, and independent. As a scientist, I know that does not happen by accident. Protein is the structural foundation of everything we are built from. As we age, our bodies become less efficient at using the protein we eat, precisely when we need it most. Most people are unknowingly starving their cells of the one nutrient that keeps them resilient, functional, and alive in the fullest sense."
Why Pure Genius beats the alternatives.
More protein and fiber. Fewer calories.
The average protein bar has a whopping 210 calories to only deliver 20g of protein. Pure Genius Protein + Fiber deliver 20g of protein and 5g fiber in just 100 calories. That's the same amount of protein in less than half the calories without the sugar, fat or carb load that comes in most bars.
Built for muscle and gut health.
Leucine signals your muscles to rebuild. Pure Genius Protein + Fiber is rich in it. The added fiber does its own work, supporting regularity and a healthy gut, so the benefits don't stop at muscle. 20g of protein, 5g of fiber, 3.38 fl oz.
Built for busy lives
Protein powder means a shaker bottle, water, two minutes of mixing, and something to clean afterward. A bar means 210 calories and 7g of fat you didn't ask for. Pure Genius Protein + Fiber is 3.38 fl oz, ready to drink. No prep. No cleanup. No trade-offs.
HOW GLP-1 USERS ACTUALLY USE IT
Shot day. Dose increase. Every day in between.
The week you move up a dose
