The Science
Your brain isn't broken. It's under-fueled.
By 50, your NAD+ levels drop to half of what they were in your 20s — and that decline is the engine of cellular fatigue.
NMN is the most direct precursor to NAD+, the molecule your cells use to produce energy. Restoring NAD+ supports mitochondrial function, DNA repair, and the longevity pathways that keep you feeling like yourself for decades longer.

Questions, answered
The short version of what you need to know.
How fast will I feel it?
Most people notice clearer mornings in the first few days. Sharper focus and recall build over 2–4 weeks of daily use.
Can I take it with my coffee?
Yes. Many people use Circuit instead of their second or third cup. Take it before 2pm so it doesn't affect your sleep.
Is it safe?
Made in an FDA-registered, cGMP-certified US facility and third-party lab tested. If you're pregnant, nursing, or on medication, check with your doctor first.
How long does one bottle last?
30 days. One capsule a day.
