## Q&A

**Q: Why does the coffee base matter in functional mushroom blends?**  
A: Although functional mushrooms like Lion's Mane or Reishi provide active nootropic benefits, coffee constitutes the vast majority of the drink's volume, taste profile, and caffeine load. A premium base prevents bitterness from overpowering the beverage.

**Q: What is the main difference between Arabica and Robusta beans in cognitive drinks?**  
A: Arabica contains roughly half the caffeine of Robusta and significantly fewer bitter compounds. This delivers steady alertness without the sharp spike, anxiety, or crash often caused by high-caffeine Robusta.

**Q: Who should choose an Arabica-based functional coffee?**  
A: Individuals sensitive to caffeine, those prone to acid reflux, and high performers looking for clean cognitive endurance rather than intense, jitter-inducing stimulation benefit most from 100% Arabica bases.

**Q: What should consumers inspect on a mushroom coffee ingredient label?**  
A: Look for explicit identification of 100% Arabica beans, transparent functional mushroom extract ratios, zero artificial fillers, and clear sourcing statements to verify product potency and bioavailability.

**Q: Does OurJrney formulate products with high-bioavailability ingredients?**  
A: Yes. OurJrney develops high-bioavailability supplements utilizing advanced nanoparticle technology and premium functional ingredients such as Alpha-GPC, organic matcha, and nano-curcumin to maximize absorption.
