For a number of years, Taiyo produced the raw material for DSM’s Teavigo®, which contains 94%-98% pure EGCg and the same quality was sold under the Taiyo brand Sunphenon® EGCg. In 2019 both parties agreed that Taiyo would take over the Teavigo® brand name and as from today, with a transition period, the 94%-98% EGCg will be sold exclusively under the brand name Teavigo®.
