Astragalus (Astragalus membranaceus) vs Cordyceps Militaris

Mechanism

Contains cycloastragenol and astragaloside IV which activate telomerase (hTERT). Adaptogenic — modulates immune function, reduces inflammation, and supports cardiovascular health. Used in traditional Chinese medicine for Qi tonification.

Contraindications

• Autoimmune conditions
• Active cancer (telomerase activation concern)

Mechanism

Cordyceps contains cordycepin (3'-deoxyadenosine) and adenosine, which modulate purinergic signaling. Cordycepin activates AMPK, inhibits mTOR, and modulates adenosine receptors (A1, A2A, A3). It enhances cellular ATP production by upregulating mitochondrial biogenesis genes and improving oxygen utilization efficiency. Cordyceps increases EPO production (erythropoietin) via HIF-1alpha stabilization, enhancing oxygen-carrying capacity. Beta-glucans (1,3/1,6) activate innate immune cells via Dectin-1 and complement receptor 3 (CR3). It also relaxes bronchial smooth muscle and enhances adrenal hormone production.
