| Attribute | 2'-Fucosyllactose (2'-FL) | Adrafinil |
|---|---|---|
| **Evidence Score** | 8/10 | 8/10 |
| **Category** | Fermented/Probiotic | Other |
| **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 | 2-[(diphenylmethyl)sulfinyl]acetamide, CRL-40028, Olmifon, diphenylmethylsulfinylacetamide, benzhydrylsulfinylacetamide |
| **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. | Adrafinil is a synthetic eugeroic compound that promotes wakefulness by converting to modafinil in the liver via hydrolysis. It enhances alertness and cognitive function by increasing dopamine, norepinephrine, and orexin levels in the brain. |
| **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 | Adrafinil acts as a prodrug that undergoes hepatic hydrolysis to form modafinil, the active metabolite. Modafinil then inhibits dopamine reuptake transporters (DAT) and blocks GABA release, while simultaneously increasing orexin/hypocretin neurotransmission in the hypothalamus. This dual mechanism e |
| **Dosage** | Commonly included in infant formulas; dosage varies. Consult a healthcare provider before use. | Typical dosage ranges from 300-600 mg per day. Available in capsules and tablets. 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 | Adrafinil may cause elevated liver enzymes due to hepatic metabolism, requiring periodic liver function monitoring with prolonged use. Common side effects include headache, nausea, anxiety, and insomnia, typically dose-dependent. It can interact with hormonal contraceptives by inducing CYP3A4 enzyme |

## 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.
