Congratulations for completing a study with Citruslabs


Sourse's philosophy is that the optimal source of nutrients is real, unadulterated food. To this end, Sourse created vitamin-enriched dark chocolate bites using only wholesome, plant-based ingredients. Self-care should be a pleasurable experience. Chocolate was a natural choice because it's a whole food that possesses inherent properties that make it an ideal vehicle for delivering vitamins.

Study results

Participants experience a significant improvement in most of the outcomes associated with vitamin B12 deficiency. Participants seemed to have improved cognitive functioning and enjoyed using the test product. Hype Bites were also effective at promoting positive changes to vitamin B12 in the blood, hopefully mitigating some adverse outcomes that could come with a vitamin B12 deficiency.

About the product

Vitamin B12 is a critical vitamin for multiple health outcomes. Individuals who consume a vegan or vegetarian diet are likely not getting enough vitamin B12 because it is traditionally found in animal proteins. To fill that void, Sourse has created Hype Bites, a once-a-day chocolate supplement containing vitamin B12 as methylcobalamin, a more digestible form of vitamin B12. To understand the effectiveness of Hype Bites, Sourse decided to run a clinical trial with Citruslabs.
