How it works

Beta-pinene is volatile and has antimicrobial activity in laboratory studies. It is studied alongside alpha-pinene for potential effects on respiratory function and inflammation. Inhaled beta-pinene contributes to the forest-like scent of pine and rosemary. When ingested as a component of essential oils, it is absorbed and rapidly metabolized. Specific human clinical data on isolated beta-pinene supplementation are limited.

Dosage

No established supplement dose. Beta-pinene is consumed in small amounts as part of foods and essential oils.

When and how to take it
