|Green tea smoothies - If you don't want to waste more than 60% of green tea's precious EGCG content, you better don't blend it with too much other stuff|
To assess the effects of different food matrices on the bioavailability of capsulated green tea supplements, Naumovski et al. came up with a systemic absorption test healthy fasted humans.
On three separate days, their four healthy, normal-weight participants (3 males and 1 female aged 18-64 years) had to come to the clinic fasted (10h of fasting minimum). At the laboratory, the participants ingested 500 mg of EGCG given either as
- two capsules (2 × 250 mg) with 100 mL of water only (without any breakfast),
- two capsules (2 × 250 mg) provided with 50 g of Special K breakfast cereal (Kellogg’s, Pagewood, NSW, Australia), or
- in form of 200 mL of full cream milk or EGCG (500 mg) that had been incorporated in 200 g of strawberry sorbet
