Benefits of Chaga




Potential Health Benefits

Alternative practitioners believe that Chaga offers numerous health benefits. Among them, Chaga is believed to fight inflammation, lower blood sugar, reduce blood pressure, alleviate arthritis, and even prevent or slow the progression of cancer. Since Chaga Mushroom is an Adaptogen, it helps to bring the body back to balance, reducing oxidative stress and boosting immune function. It also has positive effects on:

  • Nervous System
  • GI Tract
  • Cardiovascular System
  • Endocrine System

Anti – Inflammatory Action:

By having these adaptogenic effects, it helps the body to cope with stress, boost health during the cold and flu season, and fight cancer. Animal and test-tube studies suggest that chaga extract can positively impact immunity by reducing long-term inflammation and fight harmful bacteria and viruses. By promoting the formation of beneficial Cytokines (specialized protein that regulate the immune system), chaga stimulates white blood cells which are essential in fighting off harmful bacteria and viruses.[i][ii]

Anti – Cancer and Antioxidative properties:

Chaga is rich in fiber and essential nutrients like Vitamin D, iron, magnesium, potassium, manganese and calcium. Due to its high melanin and antioxidant content, chaga is found to have a certain anticancer potential where various lab studies on mice[iii] and human liver cells[iv] suggest that its extract prevented cancer growth and reduced tumor size by 60%. High Melanin content in Chaga makes it a potent antioxidant with one of the highest Oxygen Radical Absorbance Capacity (ORAC) food.

Lowers Blood Sugar Levels:

Several animal studies have concluded that Chaga mushroom extracts help in lowering Blood sugar levels by as much as 31%[v] over several weeks. Another recent study in obese, diabetic mice observed that chaga extract reduced blood sugar levels and insulin resistance compared to diabetic mice who did not receive the supplement.[vi]


Chaga extract is also shown to benefit cholesterol levels, thereby reducing the risk of heart diseases. In an eight week study in rats with high cholesterol, chaga extract reduced bad LDL cholesterol, total cholesterol and triglycerides while increasing good cholesterol and antioxidant levels.

Side Effects

Though chaga extracts are well tolerated, human studies on its safety and dosage are very limited. However, it should be noted that chaga extracts could pose risk for people on insulin due to its impact on blood sugar. Also, it contains proteins that prevent blood clotting, therefore people on blood thinning medication need to be extra cautious. Due limited data research, there is no indication for pregnant or lactating women. The safest option is to avoid consumption.
