Low in Tannins and Free from Caffeine and Oxalic Acid

Caffeine is a naturally occurring stimulant present in both black and green tea. Caffeine use in moderation is typically safe. It may even improve workout performance, focus, and mood. Excessive use, on the other hand, has been related to heart palpitations, increased anxiety, sleep issues, and headaches. As a result, some people prefer to avoid or limit their caffeine intake. Because rooibos tea is caffeine-free by nature, it is an ideal substitute for black or green tea.

Rooibos also has less tannin than black or green tea. Tannins, natural chemicals found in green and black tea, inhibit nutrient absorption, particularly iron absorption. Finally, unlike black tea and, to a lesser extent, green tea, red rooibos contains no oxalic acid. Because excessive oxalic acid consumption increases the danger of kidney stones, rooibos is a suitable alternative for anybody with renal difficulties.
