| **Also Known As** | N-Acetyl-L-carnitine, ALCAR, Acetylcarnitine, LAC, N-Acetylcarnitine, Acetyl-L-carnitine HCl, Levacecarnine acetate | Agaricus subrufescens, Himematsutake, Mushroom of the Sun, Royal Sun Agaricus, Cogumelo do Sol, ABM, Princess Matsutake, God's Mushroom |
| **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. | Agaricus blazei mushroom contains beta-glucans that activate immune cells including macrophages and NK cells to enhance immune surveillance. This medicinal mushroom modulates cytokine production to reduce inflammation while providing antioxidant protection through increased cellular antioxidant acti |
| **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 | Beta-glucans in Agaricus blazei bind to complement receptor 3 (CR3) and Dectin-1 receptors on immune cells, triggering activation of macrophages, dendritic cells, and NK cells. These compounds stimulate Th1 immune responses while suppressing excessive Th2 activity, modulating cytokine production inc |
| **Dosage** | Typical dosage ranges from 500 to 2,000 mg per day. Consult a healthcare provider before use. | - Supplements: Take 1,000–2,000 mg of standardized extract daily for immune and metabolic support.
- Powder: Add ½–1 tsp of dual-extracted powder to soups, broths, or tonics.
- Capsules: Use encapsulated extract for consistent dosing, especially in integrative wellness protocols. |
| **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  | Agaricus blazei is generally well-tolerated with mild gastrointestinal upset reported in some users at higher doses. May enhance immune system activity, potentially interfering with immunosuppressive medications used in organ transplant recipients. Limited safety data exists for pregnant or breastfe |

## Acetyl-L-Carnitine (ALCAR) — Full Health Benefits

- Enhances cognitive function and memory by increasing acetylcholine levels in the brain, supporting learning and recall. - Supports energy production and metabolism by transporting fatty acids into mitochondria for efficient ATP generation. - Reduces symptoms of mental fatigue and brain fog, improving alertness and focus throughout the day. - Protects neurons from oxidative stress and age-related decline, potentially lowering the risk of neurodegenerative diseases. - Improves mood and emotional balance by modulating neurotransmitter activity. - Aids in recovery from physical and mental stress by supporting cellular repair mechanisms. - May help manage symptoms of depression and neuropathy, as shown in several clinical studies. - Supports cardiovascular health by improving blood flow and reducing oxidative damage.
