Noo Day v.2 (version 2) is the updated rendition of the original Noo Day formula. The logo on the Noo Day bottles was and continues to read: "Constant Improvement," and version 2 is a testament to this mission. Noo Day v.2 contains 4x the Noopept and nearly twice as much Aniracetam as the original - nootropics used for both their own cognitive supporting potential as well as their ability to "amplify" other supplements and limit tolerance build-up. Version 2 has dropped the NAL-Tyrosine and retained the Sulbutiamine found in the predecessor.
