2.What is a reasonable caffeine intake?
Oolong tea contains caffeine, and moderate intake can provide alertness. However, it's essential to be mindful of caffeine intake.

However, for individuals sensitive to caffeine, pregnant women, and children, attention should be paid to caffeine intake. The metabolism of caffeine slows down during pregnancy, leading to its accumulation and potential transfer to the baby through the placenta. Therefore, Oolong tea may be burdensome for pregnant women and is not recommended. For children, those under four years old should avoid caffeine, and for children aged four and above, the recommended intake is approximately 1 milligram per 2.5 kilograms of body weight.
3.What are the effects of caffeine?
Caffeine is a compound known as methylxanthine, and it acts as a stimulant. Its primary stimulant effect is due to its binding to adenosine receptors in the brain. Adenosine, a byproduct of energy production (ATP), attaches to receptors throughout the day, causing a feeling of tiredness. Because caffeine structurally resembles adenosine, it can replace adenosine on these receptors, alleviating the feeling of fatigue. Therefore, the beneficial effects of caffeine include alertness, fatigue reduction, and diuretic properties.

Excessive caffeine intake can lead to overstimulation and excitement, affecting the nervous system and causing negative effects such as anxiety and nervousness. It may also result in increased blood pressure and vascular stiffness.

“I’ve had Tieguanyin before but iteaworld stepped it up on quality. Sweet vegetal and creamy notes and covered the entire palate.”

"According to the package, this tea comes from old trees that are older than 100 years old.
Since I have a full-size package of this tea, I decided to try it first, and boy was I taken aback by the incredibly intense peach aroma.
It made me wonder how they achieved such a strong aroma without adding any additional flavorings!
Until the third steep, following the gongfu style, the tea retained this delightful peach fragrance.
After that, the roasted undertones became more prominent, and personally, I enjoyed the tea slightly less.
Nonetheless, it is a tea that I believe will likely become one of my favorites from this selection."
