Thank you for your reply.
The shelf life is normally valid for the unopened period.
Your shelf life is 2 years in a capsule which means you have already opened our matcha packages. Therefore, our shelf life has little to do with your shelf life.
I’m not sure what nutrient is effective for 2 years or not. I believe you need to check it yourself.
However, I believe I can state on our specification sheet issued for you that it is “safe for human consumption for 2 years”
