FREQUENTLY ASKED QUESTIONS Why use Resilient Nutrition?


Switch On contains some ingredients (e.g., creatine monohydrate) that have effects that accumulate with repeated use, so some of Switch On’s benefits add up over time. This said, while there’s no obvious need to cycle on and off Switch On, it’s worth noting that the longest studies of some of its ingredients have only lasted about 8 weeks (this is true of L-theanine, for instance). These studies have all shown that the ingredients in Switch On have excellent safety profiles. Nevertheless, to be cautious, we recommend that you use Switch On somewhat intermittently. Either of the following work well:

  • Use Switch On on workdays only (e.g., Monday to Friday).
  • Use Switch On daily, but after 8 weeks of use take a 2-week break from using it before introducing it again.


We do what we can to support the health of the environment. We’re responsible in where and how we source our ingredients, we use recyclable and reusable packaging and we avoid using plastic when possible.

We respect and value the natural world. We will be donating a fixed proportion of our profits to the Coalition for Rainforest Nations, a charity that helps governments and communities responsibly manage their tropical rainforests. Rainforests are our planet’s richest areas of biodiversity, and preserving rainforests helps protect against climate change.
