It's made with only 5 wholesome ingredients and contains no fillers, artificial sweeteners, or fibre syrups. Its 25 grams of protein comes from the use of collagen in our protein bars. Your body's natural collagen production decreases as you age. Adding collagen to your diet can support skin, hair, and nail health, increasing muscle recovery rates, and reducing joint pain.


The bars' classic peanut butter cup flavour is created using peanut butter, 100% Canadian honey, and dark chocolate. We add a little bit of extra texture, energy, and fibre with rolled oats from the prairies of Saskatchewan.

Peanut Butter

High in protein, healthy fats, and nutrients like magnesium and vitamin E, peanut butter is a tasty powerhouse. It strengthens cells, reduces risk of heart disease, and makes you feel satiated and satisfied.


100% Canadian honey contains antibacterial and antioxidant properties while serving as a natural and healthy substitute to sugars or artificial sweeteners. The naturally occurring simple sugars also provides an instant energy boost.

Dark Chocolate

Dark chocolate is packed with iron, magnesium and antioxidants— all crucial for healthy psychological and physiological functions. It contains natural compounds that reduce anxiety, lowers stress levels, and supports healthy skin.


High in fiber and zinc, anti-inflammatory, lowers blood sugar, prevents cardiovascular disease... the list of benefits from eating oats goes on and on. Oats are also a source of complex carbs which helps keep you feeling fueled long after your snack.

That's it.
