| **Overview** | Acetyl-L-Carnitine (ALCAR) is an acetylated form of L-carnitine that crosses the blood-brain barrier to enhance cognitive function and cellular energy production. It works by facilitating fatty acid transport into mitochondria while supporting acetylcholine synthesis in the brain. | Affron is a standardized saffron extract containing 3.5% lepticrosalides that supports mood regulation through serotonin pathway modulation. Clinical studies demonstrate up to 50% reduction in depression symptoms and enhanced cognitive function through its antioxidant properties. |
| **Mechanism of Action** | ALCAR functions as a cofactor for carnitine palmitoyltransferase I, facilitating long-chain fatty acid transport across mitochondrial membranes for beta-oxidation and ATP synthesis. In the brain, it donates its acetyl group for acetylcholine synthesis and supports nerve growth factor production. ALC | Affron's lepticrosalides, primarily crocin and safranal, modulate serotonin reuptake inhibition and increase dopamine and norepinephrine levels in synaptic clefts. These bioactive compounds also activate NMDA receptors and inhibit acetylcholinesterase, supporting cognitive function. The extract's an |
| **Dosage** | Typical dosage ranges from 500 to 2,000 mg per day. Consult a healthcare provider before use. | Typical dosage ranges from 28 to 30 mg per day. Consult a healthcare provider before use. |
| **Safety** | ALCAR is generally well-tolerated with mild side effects including nausea, headache, and restlessness at doses above 3g daily. It may interact with anticoagulants like warfarin by enhancing their effects, requiring monitoring. ALCAR can potentially interfere with thyroid hormone function and should  | Affron is generally well-tolerated with mild side effects including nausea, dizziness, and appetite changes reported in less than 5% of users. The extract may interact with antidepressant medications, particularly SSRIs, potentially enhancing serotonergic effects. Contraindicated during pregnancy an |
