| **Also Known As** | 5'-deoxyadenosylcobalamin, Dibencozide, Coenzyme B12, AdoCbl, Vitamin B12 coenzyme, 5'-deoxy-5'-adenosylcobalamin, Active B12 | Agaricus subrufescens, Himematsutake, Mushroom of the Sun, Royal Sun Agaricus, Cogumelo do Sol, ABM, Princess Matsutake, God's Mushroom |
| **Overview** | Adenosylcobalamin is the mitochondrial form of vitamin B12 that serves as a cofactor for methylmalonyl-CoA mutase in cellular energy production. It directly supports ATP synthesis and maintains myelin sheath integrity through its role in fatty acid metabolism. | 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** | Adenosylcobalamin functions as a cofactor for methylmalonyl-CoA mutase, converting methylmalonyl-CoA to succinyl-CoA in the citric acid cycle for ATP production. It facilitates odd-chain fatty acid metabolism and branched-chain amino acid catabolism, supporting mitochondrial energy synthesis. The co | 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 dosages range from 1,000 mcg to 5,000 mcg daily, often used in sublingual or injectable forms. 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** | Adenosylcobalamin is generally well-tolerated with minimal side effects at doses up to 5mg daily. It may interact with metformin, proton pump inhibitors, and H2 blockers by reducing B12 absorption. Patients with Leber's optic neuropathy should avoid B12 supplements due to potential vision deteriorat | 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 |
