There is no clear evidence that green tea capsules are as effective as tea when it comes to weight loss or other health benefits.
Some research suggests that green tea capsules might not be as bioavailable as tea, meaning the body might not absorb all of the beneficial compounds in the capsules.
Additionally, green tea is high in caffeine and can cause nervousness and insomnia if consumed in large amounts.
Tea is a low-calorie beverage and contains antioxidants and other beneficial compounds that might promote weight loss and better health.
