If you think in antioxidants only, then yes. Green rooibos has higher levels of antioxidants than red rooibos. This month's selection, Perles de Antilles is a uniquely flavoured green rooibos.
Back to basics for a second. Rooibos tea is a herbal tea. It's made from the Rooibos plant that grows in South America. Both green and red rooibos come from the same plant. The difference between the two is in the processing. Red rooibos is oxidized (exposed to oxygen), green rooibos is not. Instead, green rooibos is dried (halted by steaming the leaves) soon after picking so that it doesn't oxidize when exposed.
Halting the oxidation process means locking in the plants natural enzymes. In general though, both types of rooibos are chalk full of healthful properties. In addition to the high antioxidant levels, rooibos is loaded with minerals that support your health like potassium, manganese, fluoride, iron, copper, zinc, magnesium and calcium. The zinc and good levels of alpha hydroxy acid makes rooibos great for healthy and clear skin. rooibos suppressed fasting glucose levels, lowers blood pressure
Drink the kind of rooibos you like better because they both have healthful properties.
