Since 2017, we have been building the Grinday brand, which was created out of a specific need - to find effective support in daily professional challenges. Exhausted by intensive work and searching for solutions that truly work, we created a product that thousands of people have come to trust. What makes us happiest is that many of you regularly return to us - this is the best proof that our approach genuinely helps in daily growth.

Our Story

Bartosz Ryłko

We have known each other since childhood, but life took us on different professional paths - Bartek became a programmer, and Kuba a civil engineer. Despite different industries, we faced similar challenges: intense mental work, time pressure, responsibility, and the need to maintain high focus for many hours.

These demands led us to search for ways to better cope with stress and keep our bodies in good shape. We exchanged observations, tested, compared results, and discussed what really works versus what is just a passing trend.

Over time, we developed our own "canon" of proven solutions. We learned to recognize which adaptogens and herbs genuinely support the body and which are just marketing noise. We also understood that simply taking supplements is not enough - the key is combining various elements: from sleep quality to diet, to stress management techniques.

Our Philosophy

Bartosz Ryłko

We believe in the concept of continuous, gradual improvement. It's not about sudden changes or temporary bursts, but about consistent, daily actions that lead to lasting development. It's like building a bridge - every element must be precisely crafted, and the whole is created step by step.

True strength does not lie in individual actions, but in a holistic approach to self-development. It's like a puzzle where every piece matters:

  • Conscious nutrition provides energy for action
  • Regular physical activity strengthens the body and mind
  • Mindfulness practices help maintain balance
  • Rest and recovery allow for full utilization of your potential
  • Natural support from herbs and adaptogens helps the body during increased demands

What Makes Grinday Unique?

Our engineering approach based on analysis and data translates into creating the highest quality products. We use patented ingredients and standardized extracts with scientifically proven effects. The ingredients in our formulas have a proven impact on the body and are carefully selected for functionality. We don't add unnecessary fillers - we focus on pure composition and transparency.

Why Was Grinday Created?

Bartosz Ryłko

Creating our own blends of adaptogens and herbs, we noticed how hard it is to find products that meet our standards. We wanted to ensure that what we consume truly works. After months of experimentation and mutual consultation, we decided to create a line of supplements that we ourselves would want to use.

Our Vision

Bartosz Ryłko

We don't sell magic pills or quick fixes. We share an approach to life where each day is an opportunity for growth. Where striving for excellence is not a burden but a natural part of the journey. Where "giving it your all" does not mean burnout but satisfaction from a job well done.

It reminds us of Bruce Lee, who said: "I do not pray for an easy life, but for the strength to endure a difficult one." His philosophy of continuous development and striving for mastery through daily practice perfectly reflects what we believe in.

We want to support people who:

  • Aspire to grow on their terms
  • Seek natural ways to enhance their abilities
  • Want to find satisfaction in every action
  • Understand that true change takes time and consistency
  • Value authenticity and quality in every aspect of life

Our Promise

  • To maintain full transparency regarding the composition and effects of our supplements
  • To use only ingredients with scientifically proven effects
