Congratulations to Parable for completing their clinical trial with Citruslabs

Parable is Effective at Promoting Brain Health Via Psychological, Physiological, and Cognitive Markers

Brain health is multidimensional. Some components of holistic brain health involve optimal physiological and neural functioning, cognitive health, and mental health markers. If one of those areas is deficient, brain health will suffer. To help foster holistic brain health, Parable has developed Daily™, a once-a-day supplement designed to promote brain health via multiple pathways.

To understand the effectiveness of Daily™ on cognitive outcomes, Parable decided to run a clinical trial with Citruslabs. 


About Parable

There's no shortcut to brain health

In order to take care of our brains properly, we must provide them with the support they require. Rather than resorting to quick fixes like caffeine, sugar, nootropics, or sleep aids that only treat the symptoms of an unhealthy brain, we must address the root cause. Our brains play a critical role in everything we do, and it is important to prioritize brain health to maintain a healthy and fulfilling life. Parable wants to make brain care a simple part of our daily routine, just like brushing our teeth.

Parable was created to help more people care for their brains in an easy and effective way. When we feel well, we are better equipped to navigate life's challenges and experiences. Ultimately, their goal is to help people become better humans by prioritizing brain health. Testing their product in a clinical trial was an obvious next step.
