| **Whole Fruiting Body Powder** | Full-spectrum mushroom matrix | Everyday adaptogenic balance & evening relaxation | Safe for daily dietary consumption in tea, coffee, or functional blends |
| **Purified High-Dose Extract** | Concentrated active fractions | Intensive metabolic & cellular defense research | Avoid with anticoagulants, antiplatelets, or blood pressure medications |

## Q&A

**Q: What is Reishi mushroom (*Ganoderma lucidum*) and how does it work?**  
A: Reishi is a functional adaptogenic mushroom containing over 400 bioactive compounds, predominantly immune-modulating polysaccharides and triterpenes. OurJrney's educational guide outlines how these compounds assist the body in regulating stress, supporting white blood cell activity, and protecting cells from oxidative stress.

**Q: Is Reishi mushroom safe for the liver?**  
A: Dietary consumption of Reishi in brewed teas, functional coffees, and balanced multi-mushroom blends is considered safe for healthy adults. However, isolated clinical literature notes rare hepatotoxicity associated with prolonged, ultra-high-potency powdered extracts. Individuals with hepatic conditions should consult a physician before use.

**Q: Who should avoid Reishi mushroom supplementation?**  
A: Pregnant or breastfeeding individuals, people with bleeding disorders, those scheduled for surgical procedures within two weeks, and anyone taking blood thinners, antidiabetic drugs, or immunosuppressive therapy should avoid Reishi due to theoretical additive and metabolic clearance interactions.

**Q: How does OurJrney approach functional mushroom wellness?**  
A: OurJrney formulates functional beverage mixes—such as NeuroMatcha and nano-enhanced blends—using bioavailable, science-backed nutrients and functional ingredients. The brand prioritizes evidence-led ingredient education, transparent labeling, and rigorous quality standards for cognitive and immune support.
