Mechanism

High-dose green tea catechins have been reported to inhibit OATP-mediated uptake of statins, modestly raising plasma levels.

What to do

Use a standardised extract at a consistent dose rather than very high intakes.

How to fit both into one day

Green tea extract (EGCG)
morningflexible

Take green tea extract with food to reduce the small risk of liver strain, and keep it an hour from any iron dose.

Statin
eveningflexible

Cholesterol synthesis peaks overnight, so most statins are dosed in the evening. Avoid grapefruit, which raises drug levels.

Putting Green tea extract (EGCG) in the morning and Statin in the evening satisfies the 0-hour separation without disrupting either one's absorption window.
