This formula's own materials state this directly, worth restating clearly: individual milligram amounts per ingredient are not disclosed in the marketing materials reviewed for this formula.
All six ingredients are named specifically — Ginkgo Biloba, Bacopa Monnieri, L-Theanine, Vitamin B12, Phosphatidylserine, Rhodiola Rosea — but individual per-ingredient milligram amounts are not stated in the materials reviewed.
Naming six ingredients is a starting point, but it's a different thing than disclosing exact potency — this formula's own materials are direct that you should always check the supplement facts panel on the bottle you actually receive.
