So before you buy green tea online, there are few factors you should consider: Always focus on buying whole leaf green tea. Consider buying a green tea package comprising loose leaves rather than tea bags. Order your green tea from a trusted seller who has significant years of experience and trustworthiness. Tea leaves in the package should contain leaves that are loose and not coiled up. There should be no harmful addition of preservatives on the leaves. The percentage of the vitamins, minerals and the nutritive constituents should be adequate and in proportion. Green tea is, thus, a useful elixir that offers several nutritive values. Drinking it can lead to swift weight loss as well.
