| **Evidence Score** | 8/10 | 8/10 |
| **Category** | Compound | Seed |
| **Also Known As** | N-Acetyl-L-carnitine, ALCAR, Acetylcarnitine, LAC, N-Acetylcarnitine, Acetyl-L-carnitine HCl, Levacecarnine acetate | Monodora myristica, West African nutmeg, False nutmeg, Calabash nutmeg, Jamaican nutmeg |
| **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. | African nutmeg (Monodora myristica) contains bioactive compounds including myristicin, eugenol, elemicin, and limonene that demonstrate significant antioxidant, antibacterial, and lipid-modulating activities through modulation of NF-κB and PI3K/Akt/mTOR signaling pathways. In vivo studies show that  |
| **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 | African nutmeg's primary bioactive compounds—myristicin, eugenol, elemicin, and α-phellandrene—exert anti-inflammatory effects by inhibiting NF-κB nuclear translocation and suppressing COX-2 and iNOS enzyme expression, thereby reducing prostaglandin E2 and nitric oxide production. Eugenol and dehydr |
| **Dosage** | Typical dosage ranges from 500 to 2,000 mg per day. Consult a healthcare provider before use. | - Common forms include powdered seeds and concentrated extracts.
- Recommended dosage for extract: 500–1,000 mg daily for cognitive and cardiovascular support.
- Recommended dosage for powdered seeds: 1–2 grams daily for digestive and anti-inflammatory benefits.
- Can be incorporated into culinary d |
| **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  | African nutmeg is generally recognized as safe when consumed in culinary amounts, consistent with its longstanding use in West and Central African cuisines and traditional medicine systems (PMID 22306470, PMID 24995835). However, myristicin in high doses may exhibit psychoactive effects and hepatoto |
