Hi Jennifer, thank you. Qualia NAD+ is designed to work beneath the surface (it's a cellular health supplement), so its primary purpose is not to deliver results you'd feel. That said, “energy” (i..e, having more energy, feeling more energetic. etc.) is the theme we most commonly get as anecdotal feedback. A more balanced mood (i.e., less moody or irritable, more calm. etc.), sleep (i..e, needing a bit less, feeling better rested, etc.) and general well-being are other areas that can be experienced. But keep in mind that everyone is unique and results vary from person to person. Please reach out to our Customer Support team at support@neurohacker.com for assistance with your account.
