A type of tea unique to Sri Lanka, Ceylon tea is well known for its health benefits. It is known to assist with weight loss through Polyphenols, a type of antioxidant that increases your body's metabolism. Ceylon Tea also boosts your immune system response to pathogens and reduces oxidative stress. The tea also contains a good amount of potassium, which acts as a vasodilator, helping to reduce tension in blood vessels and arteries. Ceylon tea also has a healthy dose of caffeine, which boosts your cognitive ability and attention, yet you can avoid the caffeine crash associated with coffee by drinking it over the course of the day.
