| **Also Known As** | 2'-FL, 2-fucosyllactose, alpha-L-fucopyranosyl-(1→2)-beta-D-galactopyranosyl-(1→4)-D-glucose, human milk oligosaccharide, HMO, fucosyl-lactose, 2-prime-fucosyllactose | Adenosine 5'-diphosphate precursor, ADO, Adenine riboside, 9-β-D-ribofuranosyladenine, Adenosine nucleoside, ATP metabolite, Cellular energy nucleoside |
| **Overview** | 2'-Fucosyllactose (2'-FL) is a human milk oligosaccharide that acts as a prebiotic by selectively feeding beneficial gut bacteria. It enhances immune function and gut health through direct binding to pathogenic bacteria and promotion of Bifidobacteria growth. | Adenosine is a naturally occurring nucleoside that binds to adenosine receptors (A1, A2A, A2B, A3) throughout the body. It primarily regulates cardiovascular function, sleep-wake cycles, and cellular energy metabolism through cyclic adenosine monophosphate (cAMP) pathways. |
| **Mechanism of Action** | 2'-FL selectively binds to α-1,2-fucosyltransferase receptors on beneficial bacteria like Bifidobacterium longum, promoting their proliferation. It acts as a decoy receptor for pathogenic bacteria, preventing their adhesion to intestinal epithelial cells. The compound stimulates short-chain fatty ac | Adenosine activates four G-protein coupled adenosine receptors (A1, A2A, A2B, A3), with A1 and A2A being most clinically relevant. A1 receptor activation decreases heart rate and atrioventricular conduction, while A2A activation promotes vasodilation and sleep regulation. These actions occur through |
| **Dosage** | Commonly included in infant formulas; dosage varies. Consult a healthcare provider before use. | Typical dosage ranges from 10-30 mg per day in supplement form. Consult a healthcare provider before use. |
| **Safety** | 2'-FL is generally recognized as safe (GRAS) by the FDA with minimal reported side effects. Some individuals may experience mild digestive discomfort, bloating, or gas during initial supplementation. No significant drug interactions are documented, though it may enhance the effectiveness of probioti | Adenosine supplementation may cause flushing, chest discomfort, and transient heart rhythm changes due to its cardiovascular effects. It can interact with methylxanthines like caffeine and theophylline, which block adenosine receptors and reduce its effectiveness. Individuals with asthma should avoi |

## 2'-Fucosyllactose (2'-FL) — Full Health Benefits

- Supports the growth of beneficial gut bacteria, enhancing gut health by increasing Bifidobacteria levels by up to 20%. This fosters a balanced microbiome, crucial for overall wellness. - Strengthens the immune system by modulating immune responses, reducing the risk of infections. This is achieved through the production of short-chain fatty acids. - Enhances cognitive development in infants by mimicking human milk oligosaccharides. This supports brain growth and function. - Reduces inflammation by promoting the production of anti-inflammatory cytokines. This can lead to a decrease in chronic disease risk. - Improves nutrient absorption by enhancing gut barrier function. This ensures that essential vitamins and minerals are efficiently utilized. - Lowers the risk of allergies by promoting immune tolerance. This is particularly beneficial in early childhood development. - Supports cardiovascular health by reducing cholesterol levels. This is achieved through the fermentation process in the colon.

## Adenosine — Full Health Benefits

- Supports cardiovascular health by regulating heart rate and blood flow, reducing the risk of arrhythmias and hypertension. This promotes a healthy heart function. - Enhances sleep quality by modulating neurotransmitters like adenosine, leading to deeper and more restorative sleep. - Supports cellular energy production by facilitating ATP synthesis, which is essential for all cellular processes. - Reduces inflammation by inhibiting pro-inflammatory cytokines, which can alleviate symptoms of chronic inflammatory conditions. - Enhances cognitive function by improving cerebral blood flow, potentially reducing the risk of cognitive decline. - Supports respiratory health by relaxing bronchial muscles, which can improve breathing in conditions like asthma. - Promotes skin health by increasing blood circulation, leading to a more radiant and youthful complexion.
