11) Lion’s Mane Decreases Inflammation

Lion’s Mane exerts an anti-inflammatory effect by reducing excessive nitric oxide, prostaglandin, reactive oxygen species, and pro-inflammatory factors such as NF-κB (R).

In mice with acute gut inflammation, Lion’s Mane improved symptoms and decreased intestinal bleeding (R).

In rats with brain injury, Lion’s Mane extract reduced infarct volume and decreased the levels of inflammatory cytokines (R).

12) Lion’s Mane Has Antioxidative Qualities

Lion’s Mane possesses anti-oxidative qualities that prevent oxidative stress-related diseases. Consumption of the boiled mushroom can eliminate peroxides and remove harmful iron ions (R).

13) Lion’s Mane Improves Cardiovascular Health and Metabolism

In rats fed a high-fat diet, Lion’s Mane reduced total cholesterol, LDLcholesterol, triglycerides and phospholipids and increased HDL cholesterol (RR).

In ovariectomized mice (a menopause model), Lion’s Mane decreased fat tissue, total cholesterol, and leptin (R).

Cholesterol-lowering effect of Lion’s Mane may be related to increased bacterial short chain fatty acid production in the large intestine, and the accelerated rate of degradation of cholesterol to bile acids (R), or the reduced ability to absorb fat (R).

Lion’s Mane also exerts anti-inflammatory effects on macrophages and prevents or ameliorates fat tissue inflammation associated with obesity (R).
