Fluid and phenolic intake of rats fed aqueous rooibos tea extract for a period of 8 weeks.

Treatment	Water/rooibos intake/day/100 g BW (mL)	Total phenolic intake (mg gallic acid equivs/day/100 g BW)	Flavonol intake (mg quercetin equivs/day/100 g BW)	Flavanol intake (mg catechin equivs/day/100 g BW)
Negative control (water)	9.29 ± 0.25^a	ND	ND	ND

RTE + RPO	8.81 ± 0.20^a	7.31 ± 0.17^a	3.83 ± 0.09^a	1.39 ± 0.03^a
RTE + t-BHP	8.99 ±0.32^a	7.45 ± 0.26^a	3.91 ± 0.1^a	1.42 ± 0.05^a

ND: not determined. Calculations of the total phenolic, flavonol, and flavanol intakes were calculated based on the soluble solid intake obtained from the average rooibos consumption per day. Values are mean ± SEM (𝑛=10). Mean followed by different superscript is significantly different at 𝑃<0.05. RTE: aqueous rooibos extract, RPO: red palm oil, t-BHP: tert-butyl hydroperoxide.
