Possible Interaction: Catechin and Green Tea Extract

supplement:

Catechin

Research Papers that Mention the Interaction

The observed variability in catechin plasma levels might contribute to interindividual variation in benefical and adverse effects of green tea polyphenols.
PloS one  •  2018  |  View Paper
An additional human study with 5 healthy women confirmed that GTE intake sufficiently increased the concentration of gallated catechins , mainly in nonconjugated forms in LDL particles, and reduced the oxidizability of LDL.
Nutrition research  •  2016  |  View Paper
In this regard, green tea polyphenols (GrTPs) have been reported to possess properties that may increase the quality of male and female gametes, mostly via the capability of catechins to reduce ROS production.

Biotransformation of catechins improved the radical scavenging activity of GTE.
The addition of GTE to the enzyme reaction resulted in a significant increase in degallated catechins , including gallic acid, a product of the tannase reaction (314.5-4076.0 µg mL(-1)) and a reduction in epigallocatechin gallate (EGCG).

Plasma catechins concentrations increased following ingestion of the GTE confection.

Besides GTE’s direct radical scavenging properties, pre-incubation with both GTE and catechins protected osteoblasts from CSM-induced damage.
ResultsCo-, pre-, and post-incubation with GTE and catechins significantly reduced ROS formation and thus improved the viability of CSM-treated osteoblasts.

We further hypothesised that Green tea exposure will enhance memory persistence as catechins in green tea are shown to be cognitive enhancers.

Green tea extracts contain a highly variable content of catechins including (-)-epigallocatechin gallate, the major catechin in green tea formulations.

Although green tea extract and black tea extract contain over 1 mM of catechin, incubation with 0.01 mM of catechin was enough to reduce the survival ratio of Kudoa to 20%.

Taken together, these results suggest that catechin present in green tea extract might behave as antithyroid agent and possibly the consumption of green tea at high dose could alter thyroid function adversely.
