Experience the best protein bars made with premium ingredients, made-to-order from our kitchen to your door.


Our protein bars are unlike any you will have tried. They are made with smooth peanut butter, Belgian dark chocolate, and 100% Canadian honey to deliver a delicious decadent protein bar.


With our high quality ingredients,  you can always have a convenient source of clean nutrition that you can be confident in choosing. It's made with only 5 ingredients and contains no fillers or artificial sweeteners. We've done many taste tests to find the best tasting and highest quality ingredients and suppliers.


The 25 grams of protein comes from the use of collagen. We chose collagen because it is found in all connective tissue in your body. Adding collagen to your diet can support skin health, increase muscle recovery rates, and reduce joint pain. We have had many consumers report improvements in all these areas but results may vary.


Lastly, our bars require no refrigeration and their durable packaging means that they can last long stints in your emergency kit or camping bag. Odds are you will find a reason to eat them quickly.

"It's nearly impossible

to find a protein bar these days that

doesn't have added oils and fillers.


But Zentein has solved this issue

with a great tasting grab and go.

I'm extremely picky with quality,

but I'm more than happy

to recommend Zentein

to clients and consume them myself!"

"I was amazed by quality of the ingredients in the bars! Every ingredient is something we can pronounce and we know exactly what it is.

I love having them on hand so I can grab one on the go, in between clients, or after my workouts. I also love that I have the option to give one to my son before or after his sports activities. 


It feels good to have a healthy option out there that aligns with my beliefs!!"


"As someone who has tried over a dozen different protein bars I can say that this one has been the best one overall that I have ever had.

I also have a big sweet tooth this hits just the spot while giving me the protein I need. The extra benefit you get from these bars comes from the collagen which I noticed has  given me stronger nails which grow a lot faster. 

- Alexa Paulos, Founder of Western Women in Fitness Club


"Zentein is changing the game with the best protein bars. With only 5 ingredients and such great macros, you really cannot go wrong!

I normally take one to work with me instead of having to make a meal and pack it, so it's such an easy and guilt free alternative.


I've never experienced such amazing customer service either! Honestly don't take my word for it, TRY THESE BARS. I promise you won't be disappointed."

"Without a doubt one of the best protein bars I've tried! I'm able to eat this as a full meal replacement when I'm trying to put on muscle AND when I'm cutting down

for a competition.


This is definitely the best all around bar

on the market."

"Highly recommend this company and their protein bars.


As an athlete myself, I have 1 of these daily and it's the best for a meal replacement

or when you just want a snack!

I also love the fact that they added collagen into these bars.


I've noticed a huge difference in length of my hair and having thin eyebrows made them thicker which is awesome! Best protein bars out there!"

Great for young athletes too!


"After a hard workout and not a lot of time for a lunch break, I eat a Zentein protein bar. It is just what I need to fuel my body and maintain my healthy habits.

Thank you Zentein

Thank you Zentein Nutrition"

Eradicating Polio with the Rotary Club of Fort Erie

Zentein Nutrition partnered with Rotary Club of Fort Erie to provide protein bars to fuel their members, volunteers, and bikers as they raised over $200,000 for the fight against polio. We continue to support their club.

As a founding partner of the Global Polio Eradication Initiative, Rotary International has helped to reduce polio cases by more than 99.9% since 1979. If all efforts stopped today, within 10 years, polio could paralyze as many as 200,000 children per year.
