Backed by science
We work closely with our medical advisory board to ensure our boosters are highly effective. We provide complete transparency into our research so you can decide for yourself.

One step further
In addition to being organic and non-gmo project verified, all of our ingredients and finished products undergo a very rigorous five-step lab testing protocol to ensure purity and safety:

  1. We test ingredient integrity. The lab analyzes each ingredient upon delivery to ensure it is exactly what it’s supposed to be and nothing else.
  2. We test microbial counts. Microbial counts, yeast and mould tests are done to ensure safety.
  3. We analyze for pathogens. Pathogen analysis is performed to make sure ingredients contain absolutely no salmonella, escherichia coli, staphylococcus or pseudomonas aeruginose. 
  4. We analyze for pesticides. All ingredients are individually certified organic. Nonetheless, a pesticide analysis is performed as an extra precautionary measure.
  5. A final test. We perform a final microbial, pathogen and gluten analysis on the finished product to ensure nothing was introduced in the manufacturing process.

The best little combo!! The best part ... it works!!. A little boost in the morning and a calm in the evening. Zero side effects from either. They both have been a staple in my routine.
