Chaga ORAC Scores and Melanin Content: Separating Marketing from Molecular Science

Inonotus obliquus, commonly known as Chaga, is a sterile conk that grows primarily on birch trees in subarctic climates. It is frequently marketed as a "superfood" boasting astronomical ORAC (Oxygen Radical Absorbance Capacity) scores. But what does the science actually say?

Understanding the ORAC Score

The ORAC score measures a substance's ability to neutralize free radicals in vitro. Chaga regularly scores among the highest of any natural food, surpassing acai and blueberries. This immense antioxidant power is largely attributed to its Superoxide Dismutase (SOD) content and its high concentration of polyphenols.

The Power of Fungal Melanin

The distinct black exterior of the Chaga conk is composed of extremely high levels of melanin.

• DNA Protection: Fungal melanin has a unique molecular structure that excels at scavenging free radicals and protecting cellular DNA from oxidative stress and UV radiation.
• Skin Health: Regular consumption of dual-extracted Chaga is theorized to support dermal health and elasticity via this melanin-rich profile.

The Betulinic Acid Factor

Because Chaga grows on birch trees, it absorbs betulin from the bark and converts it into betulinic acid, a compound studied for its potent cellular-protective properties.

To reap these benefits, avoid raw Chaga powder. Only a proper dual-extraction can yield the water-soluble antioxidants and the alcohol-soluble betulinic acid.
