Human Evidence
Human clinical research carries the most weight.
Every decision behind Morning Clarity starts with evidence. We look at the strength of the research and how directly it applies to the specific strain and outcome.
Human clinical research carries the most weight.
Research on the specific strain matters more than evidence from a related strain.
We communicate what the evidence supports — and where it does not.
What does the gut-brain axis mean?
It simply describes how signals travel between your digestive system and your brain. Researchers study this connection to better understand areas such as stress, sleep, and everyday wellbeing.
Your gut and brain are in constant communication. Scientists call this two-way network the gut-brain axis.
The connection is only part of the story.
Not every probiotic strain has been studied for the same outcomes. The research depends on the specific strain, dose, and people studied.
Meet ProbioBrain™
B. longum 1714™ is the strain in Morning Clarity most directly studied in human gut-brain research.
The gut-brain axis is an active area of scientific research. Research on one probiotic strain should not be assumed to apply to all probiotics.
Bifidobacterium longum 1714™ is the strain in Morning Clarity most directly studied in human gut-brain research.
It has been studied in areas including everyday stress response, brain activity, sleep quality, and wellbeing-related outcomes.
These studies inform our approach to everyday stress support and sleep-related wellness.†
A human study examined acute stress response, daily stress, and neurocognitive measures.
A randomized placebo-controlled study examined brain activity during a social stress task using MEG.
An 8-week randomized placebo-controlled study in 89 adults examined sleep quality, daytime functioning, social functioning, and vitality.
What does this mean for Morning Clarity?
These studies help inform how we communicate the role of Bifidobacterium longum 1714™. Evidence from one strain or study does not automatically apply to every person or probiotic product.
Research can be positive, mixed, or inconclusive.
We look at the full body of evidence, including findings that do not support a primary outcome. This helps keep our communication aligned with what the research actually shows.
Morning Clarity combines four named probiotic strains. Each has a different research profile and contributes to the formula in its own way.
The strain in the formula most directly studied in human gut-brain research, including everyday stress response, brain activity, and sleep-related outcomes.†
A well-researched probiotic strain with extensive strain-specific research across digestive and immune wellness.†
A well-studied probiotic strain with extensive research related to digestive and immune wellness.†
A complementary strain included as part of the formula's broader digestive wellness approach.†
Different Evidence. One Formula.
The four strains are not treated as interchangeable. We consider the evidence for each strain separately when evaluating its role in Morning Clarity.
Research is the starting point. We evaluate what it tells us, where it applies, and where its limits are before it informs a formulation or a consumer-facing statement.
We look for human research, with particular attention to evidence on the specific probiotic strain.
We consider the study design, population, strain, dose, outcomes, and limitations.
Evidence helps inform how each strain fits within the broader formula.
Our communication is kept no broader than what the evidence can reasonably support.
A study does not automatically become a product claim. We use evidence to understand what can be responsibly communicated—and what should remain outside the claim.

Published research referenced throughout the Science page is listed below by strain.
Reference Note
Research involving a related strain, species, genus, or multi-strain formulation is identified as such. These studies provide scientific context and do not establish the efficacy of Morning Clarity as a finished product.
Evidence from an exact strain does not necessarily establish that the same outcome will occur with Morning Clarity, as study populations, formulations, doses, durations, and study conditions may differ.
