Bifidobacterium longum 1714 is a particular strain of beneficial bacteria found naturally within the human gut. This specific microorganism, sometimes referred to as 1714™, has undergone extensive scientific investigation. The effects of probiotics are highly strain-specific, meaning that different strains, even within the same species, can have distinct impacts. Therefore, the observed benefits of Bifidobacterium longum 1714 are unique to this particular strain and may not be replicated by other Bifidobacterium longum varieties.
The Gut-Brain Connection
The gut and the brain are in constant communication through the gut-brain axis. This bidirectional pathway involves various systems allowing signals to travel between the digestive tract and the central nervous system. For instance, the vagus nerve acts as a direct neural highway, transmitting information from the gut to the brain and vice versa.
Beyond direct nerve connections, gut bacteria can produce neuroactive compounds, including neurotransmitters like serotonin, dopamine, and gamma-aminobutyric acid (GABA). They can influence signals sent to the brain. This intricate communication network highlights how changes in the gut microbiome can influence brain function and behavior. Probiotic strains that positively affect mental health and brain function through this axis are often referred to as “psychobiotics”.
Mental and Cognitive Effects
Bifidobacterium longum 1714 has been studied for its influences on mental and cognitive well-being in healthy individuals. Research indicates that regular consumption of this strain can reduce self-reported daily stress levels. It also attenuates the physiological response to acute stress, such as social stressors, by reducing cortisol output. This suggests an improved ability to cope with stressful situations.
The strain’s effects extend to mood, with studies showing reductions in anxiety scores following social stress. It can support feelings of calmness and relaxation, and some users have reported an increase in perceived energy and vitality. Furthermore, Bifidobacterium longum 1714 has demonstrated subtle improvements in cognitive functions, particularly visuospatial memory. This includes enhanced frontal midline electroencephalographic mobility, an electrical activity pattern consistent with improved memory.
General Probiotic Functions and Gut Health
Beyond its effects on the brain, Bifidobacterium longum 1714 also contributes to gut health. It supports the integrity of the gut lining, which acts as a barrier protecting the body from harmful substances. Maintaining a robust gut barrier is foundational for digestive wellness.
This bacterium also contributes to a balanced gut microbiome by competing with less desirable microbes for nutrients and adhesion sites. This helps maintain a favorable microbial environment and supports natural digestive processes. A balanced gut microbiome can also aid in general digestive comfort, potentially reducing occasional gas, bloating, and irregular bowel movements.
Safety and Practical Considerations
Bifidobacterium longum 1714 is recognized as safe for consumption by healthy individuals and is well-tolerated. It was isolated from a healthy human gut and proven to survive the harsh environment of the human digestive tract. Most studies have shown its safe use for periods up to one year.
While well-tolerated, some individuals might experience mild, temporary side effects like gas or bloating, especially when first beginning supplementation. These symptoms often subside as the body adjusts. Bifidobacterium longum 1714 is available in supplement form. Look for products that clearly state the specific strain, often indicated by the 1714™ designation, to ensure the intended benefits. As with any new supplement, consulting a healthcare professional is advisable to ensure it is appropriate for individual health needs.
