Will the green tea extract in my Protein Powder affect my sleep?

If you are worried about the naturally-occurring caffeine content of green tea extract, note that 1 serving contributes roughly 5mg of caffeine, which is almost negligible. That said, if you want to make sure your Protein Powder is entirely caffeine free, we recommend any of our blends except the Lean Whey Protein and the Lean Plant Protein.
