White tea comes from the young leaves and buds of Camellia sinensis. The leaves go through minimal processing. You can drink it as brewed tea or take it as a concentrated extract in capsules or liquid.
Brewed white tea supplies catechins, a class of antioxidants. These compounds help shield cells from oxidative stress. Many people enjoy 1 to 3 cups a day as part of a general wellness routine. Extract supplements are usually taken with a meal.
Watch the caffeine. Sensitive people may notice insomnia, jitters, or a quicker heart rate, especially above 5 cups a day. The tannins and catechins can also block some non-heme iron absorption. If your iron levels are low or you take iron pills, keep that in mind. Heavy intake might interfere with anticoagulant drugs like warfarin because of its vitamin K and flavonoid content, though the effect is milder than what you see with fish oil.
